TR9501-CS 951108To: Ken Griffin, P.E., City Engineer/Assistant City Manager From: Atul Patel, E.I.T., Graduate Engineer RE: Signal Study - MacArthur and Parkway Blvd. Date: November 8,1995 I have completed a study to determine if a traffic signal is justified at the intersection of MacArthur and Parkway Blvd. The investigation included 24-hour machine vehicle counts, on- site rush hour vehicle counts, and a review of the accident history in the past 2 years. In order to justify the installation of a signal at MacArthur Boulevard and Parkway Boulevard, I performed a traffic signal warrant study, which includes requirements developed by the State of Texas and used consistently across the nation. Vehicles are counted and compared to the following minimum requirements with the 85th percentile speed on the major street greater than 40 mph. Warrant 1:420 vehicles per hour (both directions) for the 8th highest hour on MacArthur Blvd. and 140 vehicles per hour for the 8th highest hour on Parkway Blvd.(one approach only). Warrant 2:630 vehicles per hour (both directions) for the 8th highest hour on MacArthur Blvd. and 70 vehicles per hour for the 8th highest hour on Parkway Blvd. (one approach only). The number of vehicles counted on Parkway Boulevard did not meet the minimum requirements listed for Warrant 1-Minimum Vehicular Volume. The eighth highest hour volume of traffic on Parkway was approximately 56% of that required each hour for Warrant 1. The number of vehicles counted on Parkway Boulevard for the eighth highest hour did meet the minimum requirements listed for Warrant 2-Interruption of Continuous Traffic, but the number of vehicles on the major street did not. The eighth highest hour volume of traffic on MacArthur Boulevard was approximately 99 % of that required each hour for Warrant 2. Since the volume of traffic on the major street for the 8th highest hour is so close to meeting the warrant, I feel that it meets the requirement. The signal warrant study also requires a 12-month accident history review. The minimum criteria for Warrant 6 establishes a threshold of 5 or more accidents within a 12-month period which could have been prevented by signal control. Our police accident reports indicate that over the past 24 months, there has been zero (0) accidents reported to the police at Parkway and MacArthur Blvd. The summary of signal warrant analysis table indicates that the intersection meets Warrants 7,9,11, and 12 with an 85th percentile speed above 40 mph. The intersection was very close to meeting Warrant 2. An existing Level of Service calculation was performed for the intersection in the morning rush hour and also for the evening rush hour. The results showed a LOS F for both the EB & NB left turn movements in the am peak hour. Also, the pm peak hour showed a LOS F for the EB left turn movement. With a signal installed, the LOS for the EB & NB left turn movements would result in a level of service "C" or better, depending on the cycle length and effective green time for each turning movement. Due to the fact that the intersection met several of the warrant requirements, a signal is recommended at the intersection. I have included the warrant analysis, traffic counts, accident reports, and level of service results for your information. ap EXECUTIVE SUMMARY SUMMARY OF SIGNAL WARRANT ANALYSIS MacArthur Blvd. at Parkway Blvd. Warrant Minimum Vehicular Volume !.
