29.8 Seperated Bicycle Lanes Separated bicycle lanes parallel roads but are physically separated from vehicle traffic. Common barriers used for this purpose include curb separations, landscaped medians, flexible delineators, bollards, or other vertical structures....
29.6 Bicycle Lanes Most bicyclists prefer bicycle lanes that are physically separated from through lanes. However, dedicated bicycle lanes that are not physical separated also reduce crash potential, lower the risk of bicycles striking the doors of parked cars, and...
29.4 Markings for Bicycles at Intersections When designing intersections, it is important to attend to potential conflicts between all users — not just motorists. The growing number of large vehicles on roads can imperil bicyclists. Larger vehicles, infotainment...
29.2 Signals and Signal Timing for Bicycles at Intersections Historically, road designs and traffic signal timings have not focused on accommodating bicyclists. With bicyclist numbers increasing, it is critical to ensure bicyclists have enough time to cross...
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...
