| 摘 要： | 较大的缘石半径有利于提高路口转弯车辆的车速,但同时使得交叉口范围扩大,车辆在交叉口的清空时间延长,从而导致交叉口通行能力降低。该文通过对典型交叉口的清空时间分析证明,交叉口缘石半径越小,交叉口通行能力越大,最小缘石半径就是最合理的缘石半径。

| Abstract: | The larger curb radius is favorable for enhancing the speed of the vehicles turning at the intersections, but simultaneously makes the range of intersection enlarge and the clearing up time of the vehicles at the intersections lengthen so as to lead the traffic capacity of the intersection decrease. After the analysis of the clearing up time of the typical intersection, the article proves that the smaller the curb radius at the intersection is, the larger the traffic capacity of the intersection is. The min... |
