28.10 Selecting Beacons for Improving Pedestrian Conspicuity at Crosswalks Pedestrian-activated beacons are critical for alerting motorists that pedestrians are in the crosswalk or preparing to enter the crosswalk. Figure 28.1 is a decision tree for selecting the...
28.8 Improving Pedestrian Visibility and Conspicuity at Crosswalks Several treatments are available to increase motorist awareness of crosswalks, draw attention to pedestrians, and make pedestrians easier to detect. In addition to treatments listed in Table 28.3,...
28.6 Speed-Calming Countermeasures at Crosswalks As vehicle speed increases, motorists have greater difficulty detecting and reacting to pedestrians in their peripheral vision. As higher speeds, braking distance increases as well. Both conditions can increase crash...
28.4 Countermeasures to Reduce Pedestrian Exposure to Vehicles at Crossings Several countermeasures are available to physically protect pedestrians from traffic and reduce the amount of time required to cross a street. Table 28.1 lists design guidelines for three...
28.2 Task Analysis of Pedestrian Crossing in a Multiple Threat Scenario On a four-lane divided highway, a pedestrian who crosses in front of a stopped vehicle is exposed to a higher risk of being struck by a second vehicle traveling in the adjacent lane. Designs can...
21.12 Characteristics of Effective Lighting at Intersections Fixed intersection lighting should enhance intersection visibility while minimizing glare. Select a pole height, luminaire type, and luminaire cutoff that provides sufficient, uniform coverage through the...
