30.6 Guide Signing at Roundabouts Many motorists remain unfamiliar with roundabouts and how they are supposed to navigate them. Installing signs that provide clear guidance on the direction of travel is imperative. For multilane roundabouts, signs need to contain...
30.4 Increasing Driver Yielding Rates at Roundabouts Many motorists overlook pedestrians as they enter roundabouts because they place their focus on evaluating gaps between upstream vehicles. Motorists exiting roundabouts accelerate, making it more difficult to stop...
30.2 Reducing Vehicle Speeds Approaching Roundabouts Lowering the speed of vehicles approaching roundabouts improves yielding behavior, heightens motorist awareness of pedestrians and bicyclists, and mitigates crash severity. Designers can leverage several strategies...
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...
