30.8 Accommodations for Bicyclists at Roundabouts Roundabouts have lower crash rates than conventional intersections, but they can see more bicycle crashes than four-legged intersections. Applying one or more of the following countermeasures will enhance bicyclist...
28.16 Pedestrian Rail Crossing Safety Design features and/or warning devices at rail crossings need to provide pedestrians enough warning of approaching trains, force the pedestrian to look for trains, or prevent crossings entirely. Table 28.5 lists design guidelines...
28.14 Design Challenges for Older Pedestrians Older pedestrians sometimes have physical, cognitive, or age-related impairments that prevent them from crossing streets at the same speeds as younger pedestrians. The tend to have longer start-up/reaction times, walk...
28.12 Influence of the Built Environment on Pedestrian Crossing Safety Many features of the built environment influence the likelihood of pedestrian-vehicle crashes. Table 28.4 lists some of these factors, their impact on pedestrian crash potential, and...
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,...
