| 摘 要： | 为评价农村公路安保设施的有效性,提出了速度、行车轨迹、生理、交通事故以及满意度等5个评价指标,并对其适用性进行了分析;结合实际观测数据,举例说明速度和行车轨迹指标的应用.分析表明:速度和行车轨迹指标可在较短的时间内对部分微观层面的农村公路安保设施的有效性进行评价;生理、交通事故以及满意度指标均可用于微观和宏观两个层面的安保设施有效性评价,但在应用的过程中均有一定的限制性.

| Abstract: | In order to evaluate the validity of safety facilities in rural highways,five indices including speed,driving trajectory,physiology,traffic accidents and Satisfaction were proposed and the applicabilities were analyzed.Using field investigation datum,two analysis examples were given to illustrate the application of speed index and driving trajectory index.The results show that speed index and driving trajectory index can be used to evaluate the validity of some micro-level safety facilities in rural highways in a short time.Physiology index,traffic accidents index and satisfaction index can be used to evaluate the validity of safety facilities from macroscopic and microcosmic levels,but there are some limitations in application. |
