30.10 Countermeasures for Improving Accessibility for Vision-Impaired Pedestrians at Roundabouts Compared to pedestrians with no vision impairments, pedestrians who have vision impairments typically have longer wait times at roundabouts because they are unable to take...
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 Build 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...
