seconds of corridor delay. The second lane allows eastbound vehicles to get through <br /> the Owens Drive and Willow Road intersection and the Owens Drive at Iron Horse Trail <br /> intersections sooner. This is the result of the stopped vehicles being closer to the limit <br /> line when they wait for the green light. This project, however, is estimated to cost more <br /> than $1 million to construct. Staff does not recommend constructing the additional <br /> eastbound travel lane. While this construction would reduce the travel time for <br /> eastbound motorists by approximately 20 seconds during the PM peak hour between <br /> Willow Road and Owens Drive, there are other alternatives that can take advantage of <br /> evolving technology to provide some travel time savings at a lower cost and with fewer <br /> potential impacts on pedestrians and cyclists in the area. <br /> Alternatives (1, 2, & 3) <br /> Alternative 1 (coordinate Owens Drive signals focusing on vehicle progression) showed <br /> a 13 second reduction in corridor delay bringing the total down to 121 seconds of <br /> corridor delay. Implementing a new traffic signal timing program with our existing <br /> software does not have a monetary cost, but Alternative l's focus on vehicle <br /> progression does have the drawback of a significant increase in pedestrian delay. The <br /> average pedestrian would have to wait an additional 33 seconds. Implementing a signal <br /> timing plan that focuses on vehicle progression will increase the average pedestrian <br /> delay at the Iron Horse Trail Crossing from 54 seconds to of 87 seconds of delay. <br /> Previous operational observations from staff identified that even the 54 seconds of <br /> existing delay is not tolerated by pedestrians and many pedestrians push the pedestrian <br /> button, wait for a while, but get frustrated with the slow response of the pedestrian <br /> crossing and decide to cross against the light. This results in a reduction in safety, as <br /> the pedestrian is deciding to cross when the vehicle traffic signal is green. <br /> Alternatives 2 and 3 were both focused on ways to coordinate the Owens Drive traffic <br /> signals without creating the <br /> increase in pedestrian delay.
