I <br /> <br />1 <br /> <br />and its associated intersection delay for a signalized and unsignalized intersection is <br />presented below. The delay for unsignalized intersections is lower for each LOS <br />compared to signalized intersections accounts for the fact that people expect a higher <br />level of service when at a stop-controlled intersection. <br /> <br />Table 3: Related LOS to Control Delav <br /> <br /> Signalized Intersection Unsignalized Intersection <br />LOS Control Dela,v per Vehicle (see.)

This is calculated by <br />dividing the total traffic using the facility by the capacity of the facility. This can then <br />determine ifa facility is sufficient to handle the traffic that is expected to be traveling on <br />it. A ratio greater than 1.00 predicts that the facility will be unable to discharge all of the <br />demand arriving on it. Such a situation would result in long queues and extensive delays, <br />or diversion to alternate routes. <br /> <br />Analysis and Mitieation <br /> <br />Each intersection was analyzed by the criteria listed above. Analysis of the 2006 <br />Existing Scenario looks at the operations of thc intersections under existing conditions <br />and volumes. The 2006 and 2016 Build Scenarios look at the traffic operations achieved <br />at the intersections with the first phase of both Developments. The 2016 Full Build <br />Scenario looks at the traffic operations with thc additional single-family homes added to <br />the 2016 Baseline + Phase l. Analysis was also completed for ten years after Full Build <br />resulting in a 2026 Full Build Scenario. If LOS D or worse is experienced, mitigation is <br />necessary to bring intersections within acceptable levels of service, if possible. These <br />scenarios are labeled Mitigated, if required. <br /> <br />Kelly Acres and Rum R:ver Prmme <br /> <br />page 4 of 7 <br /> <br /> Prepared by: <br />Bolton & Monk, Inc <br /> <br /> Traffic bnpact Study <br />I City ofRamsey, Anoka County Minnesota <br /> 53- <br /> <br /> <br />
