EXISTING TRAFFIC VOLUMES Peak hour turning movement counts were conducted on Tuesday, April 12, 2016 at the three study intersections. The counts were conducted from 7:00-9:30 AM and from 2:00-6:00 PM in order to include the peak commute hours of the day and nearby school traffic. Counts were grown by 1% per year to reflect Existing Year 2018 Conditions. Figure 3 shows the results of morning and afternoon peak hour turning movement counts conducted at the three intersections. The numbers shown in Figure 3 represent the highest one- hour time period within the morning and afternoon counts. The detailed traffic count sheets are provided in Appendix B. EXISTING TRAFFIC CAPACITY CONDITIONS Each study intersection is measured in terms of its level of service (LOS), which reflects the overall performance of an intersection. Tables 1 and 2 describe the service levels for signalized and unsignalized intersections, respectively. The performance of signalized intersections is measured by comparing the volume of vehicle traffic through an intersection to the capacity of that intersection. The performance of unsignalized intersections is measured in terms of the average delay faced by vehicles using the intersection. Table 3 shows the performance of the three intersections under Existing Conditions during the morning and afternoon time periods. As shown in Table 3, two of the three study intersections currently operate at LOS B or better during both the morning and afternoon peak hours. The intersection of Mabury Street & 17th Street currently operates at LOS A during the morning peak hour and LOS F during the afternoon peak hour, primarily because of the delays experienced by Mabury Street traffic attempting to enter 17th Street. Appendix C contains the detailed capacity calculation worksheets. 61-67
