| 摘要： | This project investigated the influence of intersection corner radius on pedestrian crashes, rightturn crashes, and right-turn vehicle speed. The corner radius can be unique to each corner at an intersection; therefore, this study assigned crashes to an intersection corner rather than to the entire intersection. This study's findings support the development of a CMF for corner radius. Assuming a baseline condition of 10 ft., the pedestrian CMFs for corner radius for the range of corner radii included in the evaluation went from 1.00 for a 10-ft. radius to 1.59 for a 70-ft. radius. This study also generated a crash prediction equation for pedestrian crashes at signalized intersections. |
