摘要
针对传统的平面交叉口安全评价方法存在的缺陷,将交通冲突技术和模糊综合评价方法引入其中。通过对交通冲突技术进行简单的介绍,对传统的评价指标进行扩展,建立了适用于平面交叉口的评价指标、评分等级。在其基础上,将交通冲突技术和模糊综合评价方法相结合,建立适用于评价平面交叉口安全的模糊综合评价模型,并结合南京市一个典型的交叉口进行了实例应用。
Aiming at the weakness of traditional evaluation methods, traffic conflict technique and fuzzy synthetic evaluation were introduced into grade crossing safety evaluatiorL Firstly, the traffic conflict techniques were introduced, the evaluation indexes were expanded, and the evaluation indexes and grading scores suitable for evaluating safety of grade intersections were set up. Then, based on it, a fuzzy synthetic evaluation was established by combining traffic conflict technique with fuzzy synthetic evaluation, which was applicable to evaluate grade intersections. The model can provide reference for grade intersection safety evaluatiorL At last, based on a typical crossing in Nanjing, a practice example was applied.
