Franks Redevelopment Traffic Study December 5,2005 Page 2 Forecasting traffic at the subject intersection for 2007 and 2017 with the proposed development in place was accomplished through a two part process. First, traffic at the intersection was increased by applying a growth factor to account for "background" traffic growth. It was assumed that traffic at the intersection will increase by 2% per year. Second, site-generated traffic from the proposed development was added to the calculated background traffic. Site-generated traffic from the proposed development (see Table 2) was distributed to the subject intersection and access points to the proposed development based on existing traffic conditions and location of land uses in the area. Figure 1(See attached sheet) shows the assumed site-generated traffic distribution from the proposed development for the PM peak hour. Table 3 indicates the 2007 and 2017 forecast traffic at the subject intersection with the proposed development in place ("Build" conditions). The traffic operations analysis for the intersection was performed using Synchrol�irnTraffc saitware and the traffic volumes froni Table 3. Traffic signal timing informa�ion for the signal at the intersection was obtained from Ranisey County. The levels of service (LOS) for the individual movements at the intersection and for the intersection as a whole are shown in Table 4. LOS D is considered acceptable for urban intersections such as the subject intersection. Since all the movements and the intersection as a whole are expected to operate at LOS D or better, the subject intersection is expected to operate adequately for all three scenarios investigated. �is addition to level of service, the traffic analysis also examined queues at the intersection. The analysis indicated a queuing concern for the WB Frontage Road approach to Fairview Avenue. For the analysis, the WB Frontage Road approach was assumed to have only one approach lane. For the 2007 Build scenario, the longest queue (95"' percentile queue) on the WB Frontage Road approach is expected to be 319 feet, while, for the 2017 Build scenario, the longest queue on the WB Frontage Road approach is expected to be 365 feet. These queues will reach the north driveway from the Franks site onto the Frontage Road. One way of reducing this queue length is to provide a dedicated right turn lane on the WB Frontage Road approach to Fairview Avenue. If a 100-foot long right turn lane is installed on this approach, the queue for this approach drops to only 105 feet for the 2017 Build scenario, and there is also an improvement to the LOS at the intersection (See Table 4). It appears there is sufficient room to add this right turn lane by widening the existing roadway to the north by about six feet. Site Review The review of the concept site plan for the proposed development resulted in the following traffic related comments: The storage area provided for the bank drive-thru area is too small and could result in vehicles queuing up into the drive aisles, especially the main easdwesi drive aisle. On�y 16 vehicles can be stored in the storage area provided, and at least space for 24 vehicles (need to assume 25-foot length for each vehicle) should be provided. One way of providing more storage space is to turn the bank building 90 degrees counter-clockwise; this puts the drive-thru on the north side of the bank. It does not appear that a bypasslescape lane is being provided for the bank drive-thru area. Having a bypass lane is recommended, since you do not want to trap someone in the drive-thru area that does not want to be there. There are sight line problems for vehicles exiting the site at the full access driveway onto the Frontage Road. Landscaping and the embankment severely limit sight distance to the west from this driveway. This has the potential for a significant safety problem. One way of resolving this
