Traffic operations at an unsignalized intersection <br />with side-street stop control can be described in two ways. First, consideration is given to the overall <br />intersection level of service. This takes into account the total number of vehicles entering the <br />intersection and the capability of the intersection to support these volumes. Second, it is important <br />to consider the delay on the minor approach. Since the mainline does not have to stop, the majority <br />of delay is attributed to the side-street approaches. It is typical of intersections with higher mainline <br />traffic volumes to experience high levels of delay (i.e. poor levels of service) on the side-street <br />approaches, but an acceptable overall intersection level of serv <br />Results of the existing capacity analysis shown in Table 2 indicate that all study intersections <br />currently operate at an acceptable overall LOS C or better during the a.m. and p.m. peak hours, with <br />the existing traffic control, geometric layout, and signal timing. Furthermore, no significant side- <br />street delays were observed. However, relatively minor queuing i <br />westbound left-turn movement at the County Road E/Snelling Avenue West Ramp intersection and <br />the southbound left-turn movement at the County Road E/Old Snelling intersection during the <br />peak hours. These queues occasionally (i.e. approximately 10 to 15 percent of the peak hour) extend <br />beyond their current turn lane storage. It should be noted that there is a planned bridge <br />improvement that is expected to be constructed in the year 2015 which would provide additional <br />turn lane storage at the County Road E/Snelling Avenue ramp terminal intersections. Additional <br />details of the planned bridge improvement are discussed later in this document. <br />Table 2.Existing Peak Hour Capacity Analysis <br />A.M. Peak P.M.

Two development scenarios (i.e. Ñlikely useÒ and Ñmaximum useÒ) were identified. <br />However, for purposes of this study, the Ñmaximum useÒ was analyzed since it provides a <br />conservative estimate of the future conditions. Once fully occupied, the design capacity is expect <br />to support a total of 873 people, which accounts for approximately 203 staff and up to 670 <br />students/classroom seats. <br />
