At -grade Undercrossings <br />} <br />Figure 2.6: Lemon St. at Truslow Ave, Fullerton <br />Bicycle Signals Et Detectors at Intersections <br />At -grade undercrossing facilities for <br />pedestrians and bicyclists can be beneficial to <br />a region's bikeway network. Because they <br />require less excavation than roads, they <br />provide time and financial savings. <br />At -grade undercrossings do not require the <br />same amount of elevation change as adjacent <br />roadways because they do not have the same <br />height clearance requirements. As Figure 2.6 <br />demonstrates, the shorter the elevation <br />change (and closer to perfectly flat) the more <br />convenient the path will be. <br />Many traffic signals are not programmed or sensitive enough to <br />detect a bicyclist waiting at an intersection. When this happens, <br />bicyclists can become frustrated and attempt to cross an <br />intersection before the light changes. <br />Two innovative methods for addressing this problem are <br />bicyclist- oriented push buttons or loop detectors. Push buttons <br />work in the same way a pedestrian actuated cross signal does, but <br />it is placed conveniently next to the curb where bicyclists can <br />activate it (without having to dismount their bike) and contains <br />signage that promotes its use (Figure 2.7). <br />Another facility designed to help bicyclists at intersections are <br />conductor loops. As Figure 2.8 demonstrates, pavement <br />markings can be used in conjunction with the detector loop to <br />instruct bicyclists where to wait while at an intersection. <br />These innovative treatments are effectively address the concerns <br />of bicyclists waiting at traffic signals, while also promoting safe <br />and courteous bicycle riding. <br />Ir <br />Figure 2.7: Push - button for <br />Bicyclists <br />Figure 2.8: In- pavement Loop <br />Detector <br />OCTA Commuter Bikeways Strategic Plan 25 <br />
