Evaluation of Pedestrian Hybrid Beacons on Arizona Highways
| 项目名称： | Evaluation of Pedestrian Hybrid Beacons on Arizona Highways |
| 摘要： | A pedestrian hybrid beacon (PHB) is a device that warns and controls vehicle traffic to assist pedestrians crossing a roadway at an uncontrolled but marked crosswalk. Some Arizona local public agencies, such as the Cities of Tucson and Phoenix, have installed several PHBs within their jurisdictions, and the Arizona Department of Transportation (ADOT) has installed a few beacons at various locations on state highways. National research has reported on the effectiveness of PHBs in reducing crashes, injuries, and fatalities due to motor vehicle collisions with pedestrians and bicyclists (Fitzpatrick 2010). However, there has not been any evaluation with state-specific data to understand the impacts of PHBs on public safety in Arizona or other states. The objectives of this research are to examine the safety impact of PHBs on Arizona�s state highway system through the following tasks: (1) Evaluate the effectiveness of the highway PHBs in terms of reducing the number or severity of motor vehicle-involved collisions with pedestrians and bicyclists. This would use an expanded data sample from PHBs at similar sites across multiple jurisdictions. (2) Evaluate the degree of pedestrian/bicyclist compliance with the beacon/crosswalk combination and how that compliance impacts overall PHB effectiveness. (3) Explore the feasibility of optimal location recommendations for PHBs with respect to geography, signalized intersections, etc. (4) Review ADOT�s existing guidelines for installing PHBs on state highways and recommend modifications as needed. |
