16 Impact of the Road Diet on the Lawrence Corridor Increased motorist delay while traveling the Lawrence Corridor Depending on the time of day, travel times between Ashland Ave. and Western Ave. may increase by 3-9 mins. Current travel times for westbound evening rush hour: Western Ave. to Kedzie Ave. - 5:65 Ashland Ave. to Western Ave. 3:52 Increased motorist delay in turning off/onto Lawrence Ave and crossing Lawrence Ave. Queue Lengths will increase at traffic signals, with the heaviest at PM westbound rush hour. During peak hours, traffic will backup through side streets. Increased potential of cut-through traffic by cars and delivery vans. Traffic calming elements (speed humps) exist on numerous side streets. Corridor Impacts

17 Streetscape Changes to Mitigate Negative Impacts of the Road Diet Traffic signal timings will be adjusted to provide greater efficiency for through-traffic on Lawrence Ave. All signals 85 seconds Ped crossings between ft/second A center turn lane is being provided so that turning cars do not interrupt the flow through traffic and to facilitate cars turning onto Lawrence.

22 Traffic flow expected to remain about the same by: Making right turn bays into shared rightthrough lanes (11 parking stalls lost). Increased length of left turn storage bays on Lawrence by 90 ft. Addition of left turn signals for eastbound and westbound traffic on Lawrence. Adjustment to traffic signal timing to allow for longer greens on Lawrence. Enlargement of Intersection at Damen Ave.
