Slides from the presentation shown at this meeting can <br />be found in the appendix following this traffic study memorandum. <br /> <br />Based on feedback from all stakeholders, several improvement alternatives were eliminated due <br />to cost, constructability or impact to the recently improved school property. The two improvement <br />alternatives that were chosen for further investigation were: <br /> <br />• The potential acquisition of State property west of the north parking area to facilitate <br />providing a traditional four-legged intersection <br />• Combining pedestrian crossings to one central location and providing traffic signal control <br /> <br />These two alternatives can be implemented individually or complementary to one another. The <br />two improvement alternatives are detailed in the following section. <br /> <br />Preferred Improvement Alternatives <br />• The potential acquisition of State property west of the north parking area to facilitate <br />providing a traditional four-legged intersection: <br />o Figure 4 shows the existing property lines and a graphic of how left turns into the <br />pick-up/drop-off and west parking lot access are unable to occur safely at the <br />same time. This has resulted in the closure of the west access during peak <br />school times forcing all access and egress to one location. This has resulted in <br />extensive queuing and delay. <br />o Figure 5 shows a rough concept drawing of what could be implemented with a <br />successful land swap or ac quisition, and a graphic of how it would improve traffic <br />operations and intersection safety. <br />• Combining pedestrian crossings to one central location and providing traffic signal <br />control: <br />o Figure 6 shows how the one centralized pedestrian crossing would replace the <br />two existing crossings and where a pedestrian activated traffic signal system <br />would be located. A raised median could be constructed on the either side of the <br />crossing to further protect pedestrians. The median could only be constructed if <br />the west access is realigned as then eastbound left turns would be restricted at <br />the east access. <br />o The many advantages that come with this alternative include: <br />▪ Placing the pedestrian crossing area where only through movements are <br />being made (currently pedestrians crossing conflict with turning and <br />through vehicles). <br />▪ A protected pedestrian phase for much safer crossing without the need <br />of a crossing guard or traffic control officer. <br />▪ During off-peak times the signal would rest in green for Lake Valentine <br />Road so that vehicular traffic is unaffected. <br />▪ When a pedestrian is present and uses the push button, the signal would <br />provide a red light for vehicles and a WALK sign for pedestrians. The <br />time from pushing the button to receiving the WALK signal should be <br />minimal, and the total pedestrian phase is estimated to be less than 20 <br />seconds. <br /> <br />Two transportation scenarios were analyzed in Synchro/SimTraffic for the study area, including: <br /> <br />• Year 2020 Mid-Block Signal Only <br />• Year 2020 Mid-Block Signal and West Access Realignment <br /> <br />
