Item B: West 11th Transportation Corridor Study

th West 11 Avenue/Danebo Avenue-Willow Creek Road (AM peak hour) th West 11 Avenue/Beltline Road (PM peak hour) th Field observations on the West 11 Avenue corridor were conducted during the PM peak period and correlated with the calculated performance levels. It is apparent that coordinated signal timing within the th urbanized section of the corridor helps to minimize delays and stops for thru-traffic on West 11 Avenue. Along this segment, there were no observed vehicles queues that impacted upstream intersections. th The most congested intersection is the West 11 Avenue/Beltline Road intersection, where vehicles on both the eastbound left turn movement and southbound left turn movement do not clear every cycle during the PM peak hour. Field observations indicate that between ten and 15 vehicles do not clear the signal each cycle during the PM peak hour. It should be noted that the City conditioned a prior development to widen th the north leg of the West 11 Avenue/Beltline Road intersection to allow for future dual southbound left turn lanes. It was also observed that the corridor experiences variations (short surges in peak traffic) in traffic that lead to inconsistent travel times and driver expectations. Therefore, greater congestion and delay are experienced by those drivers that travel the corridor during the higher traffic times. The inconsistencies in corridor travel times and speeds likely contribute to the perception of greater corridor congestion than was determined from the traffic analysis. Travel Time th Vehicle travel time data was collected along West 11 Avenue between Green Hill Road and Chambers Street during the AM (7 AM to 9 AM), Mid-day (11 AM to 1 PM) and PM (4 PM to 6 PM) peak periods. The travel time data was collected in both the eastbound and westbound directions using GPS units. The thth westbound travel time runs began at West 11 Avenue/Chambers Street and ended at West 11 th Avenue/Green Hill Road (4.5 miles). The eastbound runs began at West 11 Avenue/Green Hill Road and th ended at West 13 Avenue/Chambers Street (4.7 miles). This route is longer than the westbound route th because vehicles must turn off of West 11 Avenue and drive a few blocks south to continue east on West th 13 Avenue. During the AM peak period, eleven travel time runs were completed in each direction, and during the PM peak period, eleven travel time runs were completed in each direction. For each of the travel time surveys, the intent of the survey was to match the average vehicle speed of the traffic platoon. Tables 3-5 and 3-6 summarize the average travel time runs in each direction during the AM, Mid-day and PM peak periods. As shown, travel times in both directions are longer during the PM peak hour than during the AM peak hour (volumes are also higher during the PM peak hour). In addition, AM peak hour eastbound travel times are longer than westbound times, and PM peak hour westbound travel times are longer than eastbound times. This is consistent with the relative directional volumes and the fact that the eastbound route is slightly longer. For comparison purposes, travel time runs were also performed during the mid-day peak period. The mid- day westbound travel times were consistent with the AM and PM peak surveys. However, the eastbound travel times were higher than the AM and PM peak periods. th West 11 Avenue Corridor Study September 4, 2009 City of Eugene P07265-003-000 16
