论文摘要
这项研究评估了在连续流相交(CFI)上行人自行车交叉替代方案的性能。此外,还对CFI交叉类型进行了比较与旨在提供等效体积与容量比率的标准交叉点。测试了三个CFI交叉替代方案,即传统,偏移和中间框架十字路口。总共通过合并两种自行车路径类型和两种右转控制类型来生成12种替代方案。这些方案是根据停止延迟和停站数来通过微观仿真分析的。 仿真结果表明,偏移交叉的替代性造成了所有用户类(包括电动流量)的最小停止延迟。传统的穿越产生了大多数路线类型的最少停靠点。根据交叉路口的特定起源死亡模式,中间块交叉点可以被视为对偏移或传统交叉的补充。在大多数情况下,独家自行车路径的性能要比共享使用路径更好。与等效标准交叉点相比,相对于停止延迟,汇总结果显示出所有CFI交叉类型的显着改善,但是对于大多数研究的途径,标准交叉点具有相等或更少的停止次数。关于对车辆运动的影响,偏移越过偏移产生了主要交叉路口的最低体积与容量之比。未来的研究包括纳入行人自行车的安全性,舒适性以及这些交叉替代方案对其他车辆性能措施的相对影响。
This study evaluated the performance of pedestrian-bicycle crossing alternatives at Continuous Flow Intersections (CFI). Further, a comparison was also performed of CFI crossing types against a standard intersection designed to provide an equivalent volume-to-capacity ratio. Three CFI crossing alternatives were tested, namely Traditional, Offset, and Midblock crossings. In total, 12 alternative scenarios were generated by incorporating two bicycle path types and two right-turn control types. These scenarios were analyzed through microsimulation on the basis of stopped delay and number of stops. Simulation results revealed that the Offset crossing alternative incurred the least stopped delay for all user classes, including motorized traffic. The Traditional crossing generated the least number of stops for most route types. The Midblock crossing can be considered as a supplement to either the Offset or Traditional crossing depending on the specific origin-destination patterns at the intersection. The exclusive bicycle path performed better than the shared-use path in most cases. When compared with an equivalent standard intersection, aggregated results showed significant improvement for all CFI crossing types with respect to stopped delay, but the standard intersection had an equal or fewer number of stops for most routes investigated. Regarding the effect on vehicular movement, the lowest volume-to-capacity ratio of the main intersection was incurred by the Offset crossing. Future research includes incorporating pedestrian-bicycle safety, comfort, and the relative effects of these crossing alternatives on additional vehicular performance measures.
