The directional trip distribution for the proposed <br />development is based on existing travel patterns, regional daily traffic volumes, and previous <br />studies in the area (see Figure 4: Directional Distribution). The combination of background <br />traffic and trips generated by the proposed development for year 2009 are shown in Figure 5. <br />YEAR 2009 BUILD CONDITIONS <br />To determine how well the existing roadway system will accommodate year 2009 build traffic <br />forecasts, an operations analysis was conducted during the a.m. and p.m. peak hours. Two new <br />intersections were added to this analysis; they include Cleveland Avenue/Proposed Driveway <br />and Cleveland Avenue/U-turn area. The U-turn area was located approximately 100 feet north <br />of the proposed development driveway, where the median will end and it is anticipated that <br />vehicles exiting the site may make a U-turn to access the adjacent regional roadway network. <br />Although it was recommended that the median be extended and appropriate signage be put in <br />place to discourage motorists from making U-turns at this location, the U-turn situation was <br />modeled to determine its impact on the operational characteristics of Cleveland Avenue. <br />Distribution of vehicles to the U-turn movement was determined using a route diversion analysis. <br />Data, from route diversion curves, indicates that iftwo paths are equal in travel time there will be <br />a 50/50 split of vehicles to each competing route. As the difference in travel time increases <br />between competing routes, more vehicles will use the route with the minimum travel time. Once <br />the travel time difference has increased to more than 35 percent, all vehicles will use the <br />minimum travel time route. Because the U-turn provides more than a 35 percent travel time <br />savings over other routes, all trips destined along roadways south of the proposed development <br />were assumed to make a U-turn at this location. <br />Results of the analysis shown in Table 3 indicate that all key intersections will continue to <br />operate at an acceptable LOS D or better under year 2009 build conditions during the a.m. and <br />p.m. peak hours, with existing traffic controls and geometric layout. Based on our knowledge of <br />standard safety practices, driver expectations, and the proposed site layout, the proposed access <br />is not desirable because vehicles exiting the site onto Cleveland Avenue and immediately <br />slowing to make a U-turn along this roadway from the through lane reduces the mobility and <br />safety on Cleveland Avenue. While it is difficult to quantify the safety issues presented by this <br />potential maneuver, it does violate driver expectations and adds unexpected conflicts. <br />
