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. |

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. |

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. |

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. |

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. |
