The CONTRACTOR shall make any corrections required by the ENGINEER, file with him two corrected copies and furnish such other copies as may be needed. The ENGINEER'S approval of such drawings or schedules shall not relieve the CONTRACTOR from responsibility for deviations from drawings or specifications, unless he has in writing called the ENGINEER'S attention to such deviations at the time of submission, nor shall it relieve him from responsibility for 'errors of any sort in shop drawings or schedules. It shall be the CONTRAC- TOR'S responsibility to fully and completely review all shop drawings to ascertain their effect on his ability to perform the required contract work in accordance with the plans and specifications and within the contract time. Such review by the ENGINEER shall be for the sole purpose of determining the sufficiency of said drawings or schedules to result in finished improvements in conformity with the plans and specifications, and shall not relieve the CONTRACTOR of his duty as an independent contractor as previously set forth, it being expressly understood and agreed that the ENGINEER does not assume any duty to pass upon the propriety or adequacy of such drawings or schedules, or any means or methods reflected thereby, in relation to the safety of either person or property' during CONTRACTOR'S performance hereunder. 2.13 PRELIMINARY APPROVAL.

The CONTRACTOR further agrees that the OWNER may make such changes and alterations as the OWNER may see fit, in the line, grade, form, dimensions, plans or materials for the work herein contemplated, or any part thereof, either before or after the beginning of the construction, without affecting the validity of this contract and the accompanying Performance and Payment Bonds. If such ehange~ or alterations diminish the quantity of the work to be done, they shall not constitute the bn*i* for a claim for damages, or anticipated profits on the work that may be dispensed with, except ~s provided for unit price items under Section 5 "Measurement and Pay- ment." If the amount of work is increased, and the work can fairly be classified under the speCi- fications, such increase shall be paid for according to the quantity actually done and at the unit price, if any, established for such work under this contract, except as provided for unit price items under Section 5 "Measurement and Payment;" otherwise, such additional work shall be paid for ~ provided under Extra Work. In case the OWNER shall make such changes or alterations as shall make usele,~..s any work already done or material already furnished or used in said work, then the OWNER shall recompense the CONTRACTOR for any material or labor so used, ~nd for ~ny actual loss occasioned by such change, due to actual expenses incurred in preparation for the work as originally planned. 3.

This agreement, including the specifications, plans and estimate, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and material to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. Where payment is based on the unit price method, the CONTRACTOR agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in case the actual quantity of any major item should become as much as 207~ more than, or 20% less than the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 20% of the estimated quantity. A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices.

In consideration of the furnishing of all the necessary labor, equipment and material, and the completion of all work by the CONTRACTOR, and on the completion of all work and of the delivery of all material embraced in this Contract in full conformity with the specifications and stipulations herein contained, the OWNER agrees to pay the CONTRACTOR the prices set forth in the Proposal hereto attached, which has been made a part of this contract. The CONTRACTOR hereby agrees to receive such prices in full for furnishing all material and all labor required for the aforesaid work, also for all expense incurred by him, and for well and truly performing the same and the whole thereof in the manner and according to this Agreement. 5.04 PARTIAL PAYMLNTS. On or before the 10th day of each ,,onth, the CONTRACTOR shall prepare and submit to the ENGINEER for approval or modification a statement showing as completely as practicable the total value of the work done by the CONTRACTOR up to and including the last day of the preceding month: said statement shall also include the value of ail sound materials delivered on the site of the work that are to be fabricated into the work. The OWNER shall then pay the CONTRACTOR on or before the 15th day of the current month the total amount o~ the approved statement, less 10 per cent of the amount thereof. which 10 per cent shall be retained until final payment, and further less all prbvious payments and all further sums that may be retained by the OWNER under the terms of this Agreement. It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the CONTRACTOR, the OWNER may-upon written recommendation of tbe ENGINEER-pay a reasonable and equitable portion of the retained percentage to the CONTRACTOR~ or the CONTRACTOR at the OWNER'S option, may be relieved of the obligation to fu!ly complete the work and, thereupon, the CON- TRACTOR shall receive payment of the balance due him under tile contract subject only to the conditions stated under "Final Payment." 5.05 USE OF COMPLETED PORTIONS. Tile OWNER shall have the right to take possession of and use any completed or partially completed portions of the work, notwithstanding the time for completing the entire work or such portions may not have expired but such taking possession and use shall not be deemed an acceptance of any work not completed in accordance with the Contract Documents. If such prior use increases the cost of or delays the work, the CONTRACTOR shall be entitled to such extra compensation, or extension of time, or both, as the ENGINEER may determine. The CONTRACTOR shall notify the ENGINEER when, in the CONTRACTOR'S opinion. the contract is "substantially completed" and when so notifying the ENGINEER, the CONTRAC- TOR shall furnish to the ENGINEER in writing a detailed list of unfinished work. The ENGINEER will review the CONTRACTOR'S list of unfinished work and will add thereto such items as the CONTRACTOR has failed to include. The "substantial completion" of the structure or facility shall not excuse the CONTRACTOR from performing all of the work undertaken, whether of a minor or major nature, and thereby completing the structure or facility in accordance with the Contract Documents. 5.06 FINAL COMPLETION AND ACCEPTANCE. Within ten (101 days after the CON- TRACTOR has given the ENGINEER written notice that the work has been completed, or substantially completed, the ENGINEER and the OWNER shall inspect the work and within said time, if the work be found to be completed or substantially completed in accordance with the Contract Documents, the ENGINEER shall issue to the OWNER and tile CONTRACTOR his Certificate of Completion, and thereupon it shall be the duty of the OWNER within ten (10) days to issue a Certificate of Acceptance of the work to the CONTRACTOR or to advise the CONTRAC- TOR in writing of the reason for non-acceptance. 5.07 FINAL PAYMENT. Upon tile issuance of the Certificate of Completion, the ENGI- NEER shall proceed to make final measurements and prepare final statement of the value of all work performed and materials furnished under the terms of the Agreement and shall certify same to the OWNER, who shall pay to the CONTRACTOR on or after the 30th day, and before the 35th day, after the date of the Certificate of Completion, the balance due the CONTRACTOR under the terms of this Agreement, provided he has fully performed his contractual obligations under the terms of this contract: and said payment shall become due in any event upon said performance by the CONTRACTOR. Neither the Certificate of Acceptance nor the final payment. nor any provision in the Contract Documents, shall relieve the CONTRACTOR of the obligation for fulfillment of any warranty which may be required. 5.08 PAYMENTS WITHHELD. The OWNER may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: G-10 (a) Defective .ork not remedied. (b) Claims filed or reasonable evidence indicating probable filing of claims. (c) Failure of the CONTRACTOR to make payments properly to sub- contractors or for material or labor. (d) Damage to another contractor. (e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount. (f) Reasonable indication that the work will not be completed within the contract time. When the above grounds are removed or the CONTRACTOR provides a Surety Bond ~tisfactory to the OWNER, which will protect the OWNER in the amount withheld, payment ~hall be made for amounts withheld because of them. 5.09 DELAYED PAYMENTS. Should the OWNER fail to make payment to the CONTRAC- TOR of the sum named in any partial or final statement, when payment is due, then the OWNER ·hall pay to the CONTRACTOR, in addition to the sum shown as due by such statement, interest thereon at the rate of six (6) per cent per annum, unless otherwise specified, from date due as provided under "Partial Payments" and "Final Payments," until fully paid, which shall fully liquidate any injury to the CONTRACTOR growing out of such delay in payment, but the right is expressly reserved to the CONTRACTOR in the event payments be not promptly made, as provided under "Partial Payments," to at any time thereafter treat the contract as abandoned by the OWNER and recover compensation, as provided under "Abandonment of Contract," unless such payments are withheld in accordance with the provisions of "Payments Withheld." 6. EXTRA WORK AND CLAIMS 6.01 CHANGE ORDERS: Without invalidating this Agreement, the OWNER may, at any time or from time to time, order additions, deletions or revisions to the work; such changes will be authorized by Change Order to be prepared by the ENGINEER for execution by the OWNER and the CONTRACTOR. The Change Order shall set forth the basis for any change ira contract price, as hereinafter set forth for Extra Work, and any change in contract time which may result from the change. In the event the CONTRACTOR shall refuse to execute a Change Order which has been prepared by the ENGINEER and executed by the OWNER, the ENGINEER may in writing instruct the CONTRACTOR to proceed with the work as set forth in the Change Order and the CONTRACTOR may make claim against the OWNER for Extra Work involved therein, as herein- after provided. 6.02 MINOR CHANGES: The ENGINEER may authorize minor changes in the work not incon~stant with the overall intent of the Contract Documents and not involving an increase in Contract Price. If the CONTRACTOR believes that any minor change or alteration authorized by the ENGINEER involves Extra Work and entitles him to an increase in the Contract Price, the CONTRACTOR shall make written request to the ENGINEER for a written Field Order. In such case, the CONTRACTOR by copy of his communication to the ENGINEER or otherwise in writing shall advise the OWNER of his request to the ENGINEER fbr a written Field Order and that the work involved may result in an increase in the Contract Price. Any request by the CONTRACTOR for a change in Contract Price shall be made prior to beginning the work covered by the proposed change. ~6.03 EXTRA WORK: It is agreed that the basis of compensation to the CONTRACTOR for work either added or deleted by a Change Order or for which a claim for Extra Work is made shall be determined by one or more of the following methods: Method/A)--By agreed unit prices; or Method (B)--By agreed lump sum; or Method (C)--If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced, then the CONTRACTOR shall be paid the "actual field cost" of the work, plus fifteen (15) percent. In the event said Extra Work be performed and paid for under Method (C), then the pro- visions of this paragraph shall :apply and the "actual field cost" is hereby defined to include the cost to the CONTRACTOR of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such Extra Work, plus actual transportation charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating expenses, also all necessary incidental expenses incurred directly on account of such Extra Work, including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation, and all other insurance as may be required by any law or ordinance, or directed by the OWNER, or by them agreed to. The ENGINEER may direct the form in which accounts of the "actual field cost" shall be kept and the records of these accounts shall be made available to the ENGINEER. The ENGINEER or OWNER may also specify in writing, before the work commences, .the method of doing the work and the type and kind of machinery and equip- mznt to be used; otherwise these matters shall be determined by the CONTRACTOR. Unless otherwise agreed upon, the prices for the use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified, of the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of America. Where practicable the terms and prices for the use of machinery and equipment shall be incorporated in the Written Extra Work Order. The fifteen (15%) per cent of the "actual field cost" to be paid the CONTRAC- TOR shall cover and compensate him for his profit, overhead, general superintendence and field office expense, and all other elements of cost and expense not embraced within the "actual field cost" as herein defined, save that where the CONTRACTOR'S Camp or Field Office must be maintained primarily on account of such Extra Work; then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for Extra Work of any kind will be allowed unless ordered in writing by the ENGINEER. In case any orders or instructions, either oral or written, appear to the CONTRAC- TOR to involve Extra Work for which he should receive compensation or an adjustment in the construction time, he shall make written request to the ENGINEER for written order authorizing such Extra Work. Should a difference of opinion arise as to what does or does not constitute Extra Work, or as to the payment therefor, and the ENGINEER insists upon its performance, 'the CONTRACTOR shall proceed with the work after making written request for written order and shall keep an accurate account of the "actual field cost" thereof, as provided under Method (C). The CONTRACTOR will thereby preserve the right to submit the matter of payment to arbitration, as hereinbelow provided. 6.04 TIME OF FILING CLAIMS. It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the CONTRACTOR shall be in writing and filed with the ENGINEER within thirty (30) days after the ENGINEER has given any directions, order or instruction to which the CONTRACTOR desires to take exception. The ENGINEER shall reply within thirty (30) days to such written ~xceptions by the CONTRACTOR and render his final decision-.in writing. In case the CONTRACTOR should appeal from the ENGINEER'S decision, any demand for arbitration shall be filed with the ENGINEER and the OWNER in writing within ten (10) days after the date of delivery to CONTRACTOR of the ENGINEER'S final decision. It is further agreed that final acceptance of the work by the OWNER and the acceptance by the CONTRACTOR of the final payment shall be a bar to any claims by either party, except where noted otherwise in the Contract Documents. 6.05 ARBITRATION. All questions of dispute under this Agreement shall be submitted to arbitration at the request of either party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named in writing by each party, and the third chosen G-12 by the two arbiters so aslected; or it' the arbiters fail to select · third within ten (10) days, be ~hal] be aborn by · District Judge ~wing the County in which the re·jot portion of the project is located, unless otherwise specified. Should the party demanding ·rbitration fail to name an arbiter within ten (10} d·ys of the demand, his ri{bt to ·rbitr·te shall lapse, and the decision of the ENGINEER shall be final and binding on him. Should the other party fail to choose an arbiter within ttm {10} days, the ENGINEER shall appoint such arbiter. Should either perty refuse or neglect to supply the arbiters with any papers or information demanded in writing, the arbitm are empowered by both parties to take ex parte proeec~inss. The arbiters shall net with promptness. The decision of any two shall be binding on both imrties to the contract. The decision of the arbiters upon any question submitted to ·rbitration under this contract shall be aeondition precedent to any ri~ht of legal action. The decision of the arbiter or arbiters may be fried in court to entry it into ~feet. The arbiters, if they deem the ease demands it, are authorized to ·ward the party whose contention is sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and Jf the appeal was taken without reasonable cause, they may aw·rd d·mages for any delay oecuioned thereby. The arbiters shall fix their own compensation, unless otherw, ise provided by qreement, and shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters must be re·de in writing. 7. ABANDONMENT OF CONTRACT 7.01 ABANDONMENT BY CONTRACTOR. In ease the CONTRACTOR should ·bandon and fall or refuse to resume work ~rithin ten (10) days niter written notification from the OV,~EE, or the ENGINEER, or if the CONTRACTOR fails to comply with the orders of the ENGINEER, when such orders are eonslstent swith the Contract Documents, then, and in that case, where perform·nee and payment bonds exist, the Sureties on these bonds shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the CONTRACTOR. After receiving said notice of abandonment the CONTRACTOR shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under contract for the work, may be held for use on the work by the OWNER or the Surety on the perform·nee bond, or another contractor in completion of the work; and the CONTRACTOR shall not receive any rental or credit therefor (except when used in connection with Extr· Work, where eredit shall be allowed as provided for under Section 6, Extrs Work and Cl·ims), it being understood that the use of such equipment and materials will ultimately reduce the eust to complete the work and be reflected in the final settlement. Where there is no performance bond provided or in ease the Surety should fail to commence compliance with the notice for eompletion hereinbefore provided for, within ten (10) days after service of such notice, then the OWNER may provide for completion of the work in either of the following elective manners: 7.01.1 The OWNER may thereupon employ such force of men and use such machinery, equipment, tools, materials and supplies as said OWNER may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, tools, materials and supplies to said CONTRACTOR, and expense so charged shall be deducted and paid by the OWNER out of such moneys es may be due, or that may thereafter at any time become due to the CONTRAC- TOR under and by virtue of this Agreement. In case such expense is less than the sum which would have been payable under this contract, ff the same had been completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been completed by said ~ONTRACTOR, then the CONTRACTOR and/or his Surety shall pay the amount of such excess to the OWNER; or 7.01.2 The OWNER under sealed bids, after five (5) days notice published one or more times in a newspaper having general circulation in the county of the location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which ·re provided in this contract. In case any increase in cost to the O~,~NER under the new eontract as compared to what would have been the cost under this contract, such increase shall be charged to the CONTRACTOR and the Surety shall be and remain bound therefor. However, should the cost to complete any such new contract prove to be less than what would have been the cost to complete under this contract, the CONTRACTOR and/or his Surety shall be credited therewith. When the work shall have been substantially completed the CONTRACTOR and his Surety shall be so notified sad Certificates of Completion and Acceptance, as provided in Paragraph 5.0(; hereinabove, dlall be issued. A complete itemized statement of the contract accounts, certified by the ENGINEER as being correct, shall then be prepared and delivered to the CONTRACTOP. and his Surety, whereupon the CONTRACTOR and~or his Surety, or the 01A~ER as the case may be, shall pay the balance due as reflected by said statement, within fifteen (15) days after the date of such Certificate of Completion. in the event the statement of accounts shows that the cost to complete the work is less than that which would have been the coat to the OWNER had the work been completed by the CONTRACTOR under the terms of this contract; or when the CONTRACTOR and'or his Surety shall pay the balance shown to be due by them to the OWNER, then all machinery, equipmem, tools, materials or supplies left on the site of the work shall be turned over to the CONTRACTOR and/or his Surety. Should the cost to complete the work exceed the contract price, and the CONTRACTOR and/or his Surety fail to pay the amount due the OWNER within the time designated hereinabove, and there remains any machinery, equipment, tools, materials or supplie~ on the site of the work, notice thereof, together with an itemized list of such equipment and materials, shall be mailed to the CONTRACTOR and his Surety at the respective addresse~ designated in this contract, provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held the risk of the CONTRACTOR and his Surety subject only to the duty of the 09,~EE to e×erci.~(- ordinary care to protect such property. After fifteen (15) days from the date of said notice the OWNER may sell such machinery, equipment, tools, materials or supplies and apply the net sur, derived from such sale to the credit of the CONTRACTOR and his Surety. Such sale may be made at either public or private sale, with or without notice, as the OWNER may elect. The shall release any machinery, equipment, tools; materials, or supplies, which remain on the wot':. and belong to persons other than the CONTRACTOR or his Surety, to their proper The books on all operations provided herein shall be open to the CONTRACTOR and his Sure:~. 7.02 ABANDONMENT BY OWNER. In case the O'i~ER shall fail to comply witl~ the terms of this contract, and should fail or refuse to comply with said terms within ten (10) after written notification b.¥ the CONTRACTOR, then the CONTRACTOR may suspend or wholly abandon the work, and may remove therefrom all machinery, tools and equipmeat, and all materials on the site of work that have not been included in payments to the CONTRACTOR and have not been wrought into the work. And thereupon the ENGINEER shall make an estimate of the total amount earned by the CONTRACTOR, which estimate shall include the value of work actually completed by said CONTRACTOR (at the prices stated in ,he attached proposed where unit prices are used), the value of all partially completed work at a fair and equi:abl~ price, and the amount of all Extra Work performed at the prices agreed upon, or provided for bi,' the terms of this contract, and a reasonable sum to cover the cost of any provisions made by tht CONTRACTOR to carry the whole work to completion and which cannot be utilized. The ENGINEER shall then make a final statement of the balance due the CONTRACTOR by deducting from the above estimate ali previous payments by the OV~ER and all other sums that may bf. retained by the OWNER under the terms of this Aereement and shall certify same to the OWNER who shall pay to the CONTRACTOR on or before thirty (30) days after the date of the notification by the CONTRACTOR the balance shown by said final statement as due the CONTRACTOR, under the terms of this Agreement.

(NOTE THAT THE EXTERNAL INPUT WHICN WOULD OTHERWISE BE USED TO CALL SPLIT ~"'MA¥ NOW INSTEAD BE USED IN COMBINATION WITH THE OTHER CYCLE CALL INPUTS Tu ~ALL CYCLES 5 THRU 8). COORDINATORS OFFERING ONLY FOUR (4) CYCLES, OFFERING FOUR (4) SPLITS AND FOUR (4) OFFSETS PER CYCLE MAY 8E All ACCEPTABLE SUBSTITUTE, BUT THE PROVISION OF SUCH WILL REQUIRE THE APPROVAl OF THE AGENCY. The coordination program provided in these timers .shall include the following features: A. Cycle length adjustable at least from 30 to 255 seconds, with timing and offset adjustments either in seconds or percent of cycle. B. The ability to associate the sequence of each of the four (4) left turn phases SEPARATELY FOR EACH DIAL AND SPLIT FROM THE KEYBOA~n to be: l) normal "leading" sequence (preceedlng the opposing thru phase); 2) "trailing" sequence (following the opposing thru phase); 3) to occur TWICE PER CYCLE, BOTH "LEADING" AND "TRAILING"; 4) to be OMITTED during a particular dial and split, with the calls from Its detector Input being Internally switched to the compatible thru phase In the other ring when and only when the left turn phase is thus being omitted. The ability to associate the desired type(s) of left turn operation with each dial and split combination from the keyboard shall be available for both Internal time base and external conventional hard wire system operation. The program shall also Include the capability to select these functions for "free" operation. For each controller phase there shall be two (2) force-off points provided and available for use In each coordination cycle, such that left turn phases on both streets may be brought up twice per cycle (both "leading" and "trailing") or such that the main and side street phases may be brought up and forced off twice per background cycle. THE COORDINATION PROGRAM SHALL BE OF A TYPE WHEREIN THE SET-UP OF THE -12- Ho "YIELD" ANb "FORCE OFF" POINTS HILL REQUIRL THE ENTRY OF NO MORE THAfI THREE (3) NUMERIC VALUES' IN EACH SPLIT FOR EACH TIME A PHASE l~ PROGRAMMED TO COME UP IN THE BACKGROUND CYCLE. NOTE THAT COORDINATORS EMPLOYING CIRCUIT AND INTERVAL TYPE CONTROL AND TIMINC SCHEMES WILL NOT 8E ACCEPTABlF. For dual ring and diamond interchange operation, the coordinator shall provide separate and independently adjustable "yield" points. or equivalent, for the major street phase In each ring. such that the termination point of each main street phase may be controlled with adequate precision during "lagging" left turn phase operation. The internal coordination program shall be of such a design that the controller may be operated in either semi-actuated (major street becomes non-detector extendable and rests In walk) or full-actuated mode when in coordination, as individually selected by the operator for each dial and split combination from the front panel. This design shall include activation of the pedestrian recycle function at appropriate points in the background cycle. The coordination program shall feature automatic calculation and implementation of the maximum width of the "permlsslve" period during which late side street calls may still be serviced within any given background cycle. Where time remaining in the background cycle permits, the coordinator program shall allow the side street phases to be re-serviced more than once In a given coordination cycle. This shall include automatic internal computation of the points at which each phases' vehicle and (separately) pedestrian omits shall be applied an appropriate number of seconds before the occurance of that phase's primary force-off (latching) point, to insure that no phase will be timing its minimum or pedestrian intervals when Its primary force-off occurs. The second (auxiliary) force-off shall be a non-latching pulse gated to the respective phase on. The coordinator program shall Internally provide all appropriate provisions for operation of the Call to Non-actuated, Maximum Inhibit, and Pedestrian Recycle functions on a per dial and split basis during coordination control, BOTH BY THE INTERI~AL TBC AND WHEN OPEILATING AS A HARD WIRE SECONOARY.

The scheduled night flash shall be generated either tnternai or external to the timer, and blink the load switch driver inputs independently of the cabinet (conflict monitor) flash circuitry. It shall be possible to front-panel or switch program any non -13- conflJctt.~ arrangement of amber or reo flashing movements and to program exclusive left turn and pedestrian indications to be dark during scheduled flash operation. Suitable circuitry shall be provided to permit the red monitor enable input to the confltct monitor to be deactivated during scheduled flash where requisite. Transfer between colors (stop-and-go) and scheduled night flash operation shall be in a~cordance with the intent of the MUTCO. METHOD OF INTERNAL TBC REFERENCE SYNC PULSE GENERATION. The Internal Time Base Coordinator shall internally generate the reference sync pulse from which the local offset is calculated either by the method of computation forward from a user programmable reference time of day. or by the method of generating each new cycle's first sync pulse at the time of day the new cycle Is called for ("event dependant" mode) AS SELECTEO BY THE OPERATOR ON THE FRONT PANEL. IN OROER TO INSURE EXACT CORRESPONDENCE 8ETNEEN THE "MASTER" SYNC PULSES ANO THE SYSTEM'S TIME-OF-DAY CLOCKt A SYNC PULSE SHALL Bf GENERATEO AT ANY TIME THE TIME-OF-OAY CLOCK SHONS A POINT IN TINF kNICN IS AN EXACT NUMBER OF CYCLE LENGTHS AT OR AFTER THE APPLZCASLF RESYNC TIME. METHOOS WHEREIN CYCLE COUNTERS USEO TO GENERATE SYNC PULSES ONLY UPDATE AT THE REFERENCE TIME OF. DAY WILL ROT 8F ACCEPTABLE. L. BACKGROUND CYCLE TIMER DISPLAY Suitable means shall be provided such that the count-up of the local background cycle timer may be observed in dynamic or realtime operation on the front panel display. M. COORDINATION PROGRAH INITIALIZATION Suitable means shall be provided within the coordination program such that a manual command may be entered from the keyboard to relnitlalize all coordination timings and entries to an appropriately Inactive or default value, such that the desired program may be subsequently entered without the necessity of Individually deleting unused values or entries. Preferrably, when establishing its offset from an Internal sync pulse, the coordinator should reference only the leading edge of the sync pulse, Irrespective of its width. For applicatlons where only an external sync reference Is avai)able from non-time base or other unlike types of control equipment ("color-circuit slave-off" systems), as delivered it shall be possible for the coordinator to establish its offset from an externally input sync pulse while the Internal TOO clock and event schedule remains available for the selection of all other schedulable commands. Including: Cycle, Offset. Spltt. Max II. Free, and Flash. -14- PRETIMED L TROLLER EMULATION The coordination program shall be of such a design that It may be programmed from the front panel to .precisely ·emulate the operation of a pretimed controller for applications where no detection is provided.
