本文对新建城区平面交叉口的交通安全评价方法进行了研究,为新建城区平面交叉口的设计提供了依据。论文结合西安市郭杜教育产业开发区平面交叉口的实际情况,将综合交通冲突率改造为能体现不同交通方式间冲突严重程度的偏向性交通冲突率,再将其输入到灰色聚类模型中,提出了偏向性交通冲突安全评价法。根据此安全评价方法,对西安市郭杜教育产业开发区平面交叉口的交通安全进行了评价,从5个嫌疑交叉口中筛选出较危险的2个交叉口,为开发区的规划及进一步的建设提供了参考依据。
This article has carried on the research to the traffic safety assessment method of the new urban intersection, and provides the basis for the design of the new urban intersection. Combining with the actual situation of plane intersection in Guodu Education Industrial Development Zone of Xi’an, this paper transforms the comprehensive traffic conflict rate into a biased traffic conflict rate that can reflect the severity of the conflict among different modes of transportation, and then inputs it into the gray clustering model , Proposed biased traffic conflict safety assessment method. According to this safety assessment method, the traffic safety of plane intersections in Guodu Education Industrial Development Zone of Xi’an was evaluated, and the more dangerous intersections were screened out from the 5 suspected intersections to provide planning and further construction for the development zones Provided a reference.
