四路停车控制交叉口通行能力计算

基于实际调查和观测分析,采用冲突技术法建立了机非混合交通流条件下四路停车控制交叉口机动车流的通行能力计算模型,进一步提出了422型和444型四路停车控制交叉口共用车道和拓宽路口通行能力的计算方法。通过对比冲突技术法推荐模型计算通行能力与典型交叉口观测通行能力和车队分析法计算通行能力,验证了通行能力计算模型的有效性。此外,探讨了行人流和非机动车流对机动车流通行能力的影响。最后,计算分析给出了422型和444型四路停车控制交叉口行人和自行车流量与交叉口机动车流通行能力的回归关系式,为四路停车控制交叉口通行能力的确定提供参考。

Capacities of Vehicular Movements at All-way stop-controlled Intersections

Based on the field observation,the conflict technique method was utilized to build the capacity model for solving the capacities of vehicular movements under the mixed traffic conditions at all-way stop-controlled(AWSC) intersections.Furthermore,the methodology was presented to estimate the capacities of shared lanes and flared approaches at AWSC intersections with the configurations of 422 and 444.Then,the observed capacities at several typical intersections and capacities produced by motorcade analysis method were compared with the results of the proposed model that verified the effectiveness of the methodology.In addition,the impact of non-motorized movements to the capacities of vehicular movements was explored.At last,the relationships between the volumes of non-motorized movements and the capacities of vehicular movements at AWSC intersections with the configurations of 422 and 444 were analyzed.The methodology can provide a quite valuable reference for determining the capacities of AWSC intersections.
