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

本研究试图建立一套适合推广准双车道道路的评价方法。利用微观交通模拟器，建立了专门计算两辆迎面而来的车辆在窄点相遇时的后退次数以及判断迎面而来的车辆存在的前景的方法。此外，不仅要考虑交通畅通等直接影响，还要考虑生活质量等间接影响，建立了考虑这些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.
