摘　　要：在分析主路优先交叉口交通特性的基础上,确定交通流优先等级,引入冲突技术法构建通行能力模型。以442型交叉口为例,给出不同车道布局形式下的通行能力计算模型。通过实例分析,给出了模型中各参数的建议值,并验证了模型的有效性。In this paper, based on the conflict theory, a new theoretical approach has been derived to determinate the capacities of Two-way Stop-controlled（TWSC） intersections, and take the 442 intersection as example. The priority rank of all streams involved has been considered within the new capacity model presented in the paper. The values of parameters in the models are proposed recurring to preliminary investigations of 10 TWSC intersections, and the approach is proved to be effective to determine the capacity of each stream of approaches. In conclusion, the methodology provides a quite valuable reference for determining the capacities of the TWSC intersections.
