Brian Olson, P.E. - 9 - May 31,2001 <br /> <br />CSAH 5/Dysprosium Street are expected to operate at an acceptable overall LOS D or better <br />during the a.m. and p.m. peak hours, with existing traffic control and geometric layout. The <br />proposed intersection of CSAH 5/Site Access Roadway is expected to operate at an acceptable <br />overall LOS A during the a.m. and p.m. peak hours, with side-street stop control and the <br />geometrics shown in Figure 5. <br /> <br />Table 3 <br />Year 2004 Capacity Analysis <br />Level of Service Results <br /> <br /> Level of Service <br />Intersection A.M.

The overall LOS is shown followed by the worst approach LOS. <br /> <br />Although the key intersections are expected to operate at acceptable levels of service under year <br />2004 conditions, the following suggested improvements are provided for your consideration: <br /> <br />· A westbound left-turn lane and eastbound fight-turn lane are recommended at the <br />intersection of CSAH 5/Site Access Roadway. The installation of turn lanes into the site <br />would reduce conflict between turnin~through traffic and improve safety operationsl <br /> <br />Traffic Impacts and .Calming Issues <br /> <br />Dysprosium Street <br /> <br />The City has expressed concern about the amount of cut-through traffic using Dysprosium Street <br />between CSAH 5 and CSAH 116 (Industry Avenue). Based on existing counts, approximately <br />I80 and 120 motorists currently use Dysprosium Street as an alternate route to/from the south <br />during the a.m. and p.m. peak hours, respectively. <br /> <br />As classified by the City's Transportation Plan, Dysprosium Street is a two-lane collector <br />roadway. Collector roadways, designed to provide access and mobility, are not typically subject <br />to traffic calming measures. Using the existing peak hour counts, it is estimated that Dysprosium <br />Street currently carries 2,500 to 2,900 vehicles a day. In the year 2004, the daily traffic volume <br />is expected to increase to approximately 3,500 vehicleg a day with the construction of the <br />proposed development and background growth. Since the capacity of a two-lane collector <br />roadway is 10,000 vehicles per day, the expected amount of traffic on Dysprosium Street in the <br /> <br />-276- - <br /> <br /> <br />
