摘要
以公路三支无信号交叉口为研究对象、以预测事故数和实际事故数的经验贝尔估计期望值为评价指标、以交通事故预测模型为基础、以均值度量方程为标准,对公路三支无信号交叉口的安全服务水平进行了探索性分级研究。为我国公路交叉口安全分析与评价、预防与治理的实践提供强有力的理论指导与新的方法支持。
The article studied for highway three-leg un-signalized intersections,based on accident prediction models the empirical Bayesian expected number of forecasting accidents and the actual accidents was the evaluation indicator.The mean measurement equation was the criterion,the article carried out an 2exploratory research in the level of service of safety for highway three-leg un-signalized intersections.This method will provide a strong theoretical guidance and a new technique for highway intersections safety analysis,evaluation,prevention and management.
