摘要
为了评价道路交通隔离设施的应用效果,选取试验路段观测人机冲突数据,以交通冲突率和通行能力为评价指标,对比分析栅栏式、花池式、钢管式交通隔离设施的应用效果。研究结果表明:无隔离设施相对栅栏式隔离设施降低交通冲突率84%,钢管式隔离设施降低76%,花池式隔离设施降低74%,通行能力明显提高。
In order to evaluate the application effect of road traffic barricade, experimental section hasbeen selected to observe man - vehicle collision and collect data. Then the application effects of trafficbarricade including barrier, flower and pool - and steel pipe were compared and analyzed based on thetraffic conflict rate and traffic capacity. The results have showed that without traffic barricade, the trafficconflict rate can be reduced by 84% than with barrier, by 76% with steel pipe and by 74% with flowerand pool, bringing about an obviously improved traffic capacity.
