Cimulation Bus Mobility- · Only 20% of corridor traffic would be eligible for Does not significantly circulator bus w/a maximum 2% impact on the reduce congestion in corridor. corridor. · Circulator buses would be required to travel in corridor w/general purpose traffic resulting in little benefit. · No transit provider B. Express Bus Mobility- · No transit provider Does not significantly · Express Bus requires additional facilities along reduce congestion in corridor (Park & Ride & separate lanes), corridor, resulting in excessive cost w/respect to trips reduced · Express buses would be required to travel in corridor w/general-purpose traffic resulting in little benefit. · Express Bus has no centralized origins or destinations that would result in significant ridership. · Special Events Busing does not reduce peak period congestion in corridor. C. Commuter Rail Mobility- · Mobility 2020 indicates that rail does not Does not significantly adequately address congestion in this corridor. reduce congestion in · No high-density commercial/residential links that corridor, would significantly reduce congestion. · Future rail element will be considered separately with respect to other corridors and regional benefits.

Even w/an reduce congestion in aggressive TSM Program only a 5% increase in corridor, corridor capacity would be expected. · Bottleneck improvements have already been implemented. E. Transportation Demand Mobility- · Some TDM improvements are in baseline model Management (TDM) Does not significantly representing a 5% regional reduction. reduce congestion in · Mobility 2020 indicates that TDM does not corridor, adequately address congest[on in corridor. · The corridor would require a 40% reduction regionally to accommodate 2020 traffic. Typically a max. of 8% is attributed to TDM elements. Freewa~//HOV/Express Lanes Outside SH 114/SH 121 Corridor Options 2A.
