IL <br />A special Christmas season traffic count was conducted during <br />the peak hour at the intersection of Main and Town and Country (Fashion <br />Square Entrance) to determine what changes occurred during peak shopping <br />periods. The surprising results showed that typical Christmas and <br />non -Christmas peak hourly intersection volume (5:00 PM - 6:00 PM) was <br />the same (2,535 vph during Christmas compared to 2,566 vph during the <br />non -Christmas season). <br />Intersection Capacity Analysis <br />An intersection capacity analysis was conducted utilizing PM <br />peak hour turning movement counts collected at all signalized inter- <br />sections. Appendix II -A shows the existing number of approach lanes at <br />each signalized intersection along with the PM peak hour traffic volume. <br />This information was used as the basis for the capacity analysis using <br />an Intersection Capacity Utilization (ICU) technique to report thejLevel <br />of Service. In order to calibrate the ICU analysis to the actual <br />driving characteristics of motorists encountered in the study area, a <br />special study of lane capacities was undertaken. <br />The results indicate the following lane capacities per hour of <br />green time at signalized intersections: <br />Lane Designation <br />Single Left Turn Lane <br />Dual Left Turn Lanes <br />Thru Lane (including right <br />turns) <br />Ca acit <br />1600 <br />2750 (1500 one lane, <br />1250 2nd lane) <br />1700 <br />* These are actual flow rates observed at the four approaches on the <br />intersection of Main/La Veta. The flow rate is expressed in terms of <br />vehicles per hour of green signal time. <br />775D-218 <br />
