Establishment of safety and smoothness evaluation method for suitable quasi-2-lane roads

本研究试图建立一套评价方法，以促进准双车道道路的发展。利用微观交通模拟器，建立了一种具体的计算两对向迎面车辆在窄点相遇时的避让次数和判断迎面车辆存在的前景的方法。在此基础上，提出了既要考虑交通畅通等直接影响，又要考虑生活质量等间接影响的综合评价方法。

This research tries to establish the evaluation method for promoting the suitable quasi-2-lane roads. By using microscopic traffic simulator, the method, which specifically can calculate the number of retreats when two opposite oncoming vehicles meet at the narrow point and also can judge the prospect of the existence of an oncoming vehicle, were built. Moreover, not only direct effect such as traffic smoothness but also indirect effect such as QOL, were necessary to consider, total evaluation method considering those effects were built.
