基于事故数据的公路限速标志设置合理性评估研究

Research on Rationality Evaluation of Highway Speed Limit Sign Setting based on Sccident Data

通过分析速度统计指标与事故频数和事故严重程度,从限速值和限速标志的位置两方面,运用扣分思路,计算出各线路限速标志设置的合理性得分。

Through the analysis of velocity statistics index and accident frequency and severity of accidents, values from the speed and speed limit sign position, using deduction method, to calculate the line speed limit signs setting rationality score.
