TRAFFIC PROGRESSION ANALYSIS At the City’s request, a traffic progression analysis has been performed for the weekday and Sunday peak hours to determine whether any improvements are necessary to accommodate peak hour queues. The purpose of the progression analysis is to verify the adequacy of the southbound and westbound left turn lanes at Newhope Street and Edinger Avenue and to determine the necessary lengths of turn pockets with storage and appropriate transitions (which adhere to the General Plan roadway classification for Edinger Avenue) at the Project driveways. Each weekday and Sunday peak hour has been simulated 5 times for a 60-minute period using the SimTraffic software. The progression analysis results are based on an average of all 5 simulations for each peak hour.

As shown in Table 4, the following movements are anticipated to experience peak hour queues that exceed the available storage for Opening Year (2019) With Project traffic conditions: •Newhope Street & Edinger Avenue – Southbound left turn lane would experience queues in the weekday AM and PM peak hours only. This lane is currently striped to provide 150-feet of storage, but is striped as a two-way-left-turn lane north of the intersection for approximately 640-feet to W. Regent Drive. •Newhope Street & Edinger Avenue – Westbound left turn lane would experience queues in the weekday AM and PM peak hours only.
