Effects of Traffic Calming Measures on Pedestrians and Motorist Behavior


Quiz Questions

1. The speed hump is an elongated hump with a circular-arc cross-section or flat-top, rising to a height of 76 mm (3 in) above the normal pavement surface and having a length of 3.7 m to 6.7 m (12 ft to 22 ft) in the direction of vehicular travel.
True
False
2. Raised crosswalks elevate pedestrians above the surface of the roadway and can make them more visible to motorists. Raised crosswalks cause motorists to slow at the most critical location, where pedestrians cross. They are generally designed to keep pedestrians at one level so that there is no need for curb ramps.
True
False
3. The purpose of a ____________________________is to reduce the width of vehicle travel way at an intersection or a mid-block pedestrian crossing. It shortens the street crossing distance for pedestrians, may slow vehicle speeds, and provide pedestrians and motorists with an improved view of one another, thereby reducing the risk of a motor vehicle-pedestrian collision.
Crosswalks
Bulbouts
4. Vehicles slow down as they pass over a speed hump this is represented in _________________.

5. _________________________ refers to the time that a pedestrian waits, after arriving at the curb, before he or she starts to cross the roadway.
Start Time
Wait time
6. Percentage of pedestrians who crossed in the crosswalk, before and after treatment is represented in ___________________.

7. Raised crosswalks are intended to slow vehicles down by forcing drivers to go up, across the crosswalk, and then back down again. The effect on vehicles is similar to that of a speed hump. It was hypothesized that raised crosswalks would lower vehicle speeds.
True
False
8. At the two raised crosswalks in Durham, automated traffic counters were used to measure the speeds of all vehicles, in both directions, at the crossing and about 30 m (100 ft) upstream from the crossing. The sample sizes at each site ranged from about 1,800 to 2,600.
True
False
9. Average pedestrian wait time, before and after treatment is represented in __________________________.
