February 28, 2020 Page 11 K:\014908-000\Traffic\Traffic Study\Lake Valentine Road Study.docx Year 2019 Existing Conditions The existing conditions establish a baseline from which to compare future traffic operations with. Study intersection turning movement volumes for this scenario were established through actual weekday school AM (7:40-8:40 AM) and PM (3:00-4:00 PM) school peak hour counts taken from video surveillance of the study intersections on Thursday, October 24, 2019. Raw count data is shown in the Appendix. Count data was taken for the following intersections: • Lake Valentine Road & West School Access • Lake Valentine Road & West Parking Access • Lake Valentine Road & East Parking Access • Lake Valentine Road & Bus Parking/Janet Ct • Lake Valentine Road & South Parking Access (counts from Thursday, October 10, 2019) The existing condition was analyzed from actual drone footage for both the AM and PM peak periods. The drone footage identifies issues that Synchro/SimTraffic are unable to show. The West Parking Access was closed using a police vehicle for most of the AM and PM peak time by an officer who was directing traffic. Figure 2 displays the 2019 existing AM peak hour (7:40-8:40) and PM peak hour (3:00-4:00) turning movement volumes for the approximate school peak times. During a majority of the AM and PM peak hour, there were two traffic crossing guards at the west crosswalk location, which could not be reflected in a Synchro analysis. The drone video was observed, and it was calculated that pedestrians had the right of way to cross Lake Valentine Road 43% of the AM peak period and 28% of the PM peak period time at the West School Access intersection. The footage also showed people parking on the street and in the drop- off/pick-up loop which caused obstructions and queuing issues. During the worst few minutes of the PM peak period, over 20 vehicles were queued at the East Parking Access waiting to get out and over 20 vehicles were queued on eastbound Lake Valentine Road as the traffic control officer was directing busses out of the bus lot. The inorganization of traffic during the school peak hours has created driver confusion and the intersections surrounding the school are currently operating poorly and do not provide a safe and efficient way for pedestrians to cross the street. Year 2020 Mid-Block Signal Only Condition To represent the Year 2020 Mid-Block Signal Only Conditions, this scenario assumes the existing lane geometry, access, and traffic control at existing intersections. The new mid-block signal is located between the West Parking Access and East Parking Access, with one lane in each direction of Lake Valentine Road. It was assumed that the West Parking Access would remain blocked off, and therefore any volumes that were able to use the access previously were moved to the east access for modeling purposes. The results of the 2020 Mid-Block Signal Only Condition traffic operations analysis are summarized in Table 1. The mid-block signal was modeled with a 45-second cycle length, giving 24 seconds to the pedestrian phase and 21 seconds to the vehicle phase. It was assumed that during the school peak hours, the pedestrian push button would be constantly pushed and was given the maximum amount of time while optimizing the signal. Figure 7 displays the 2020 Mid-Block Signal Only Traffic Volumes. Trips previously turning in/out of the West Parking Access when it wasn’t blocked off by an officer were redistributed to the East Parking Access. All pedestrians were relocated to the mid-block signal to cross Lake Valentine Road. As Table 1 shows the average delay for each peak hour, it is assumed that the peak 15-minute periods will experience slightly higher delays than shown.
