重庆主城区公交专用道运行保障措施探析

Research of Operation Support for Bus Lane in Metropolitan Area of Chongqing

随着城市机动车保有量不断增加,公交专用道的效果未达预期,无法持续发挥效能。其运营管理如何得到保障,成为公交优先能否有效实现的难题。分析重庆市主城区公交专用道运行效率持续下降的成因,提出“山水分割、中心组团式”的重庆主城区应以智能管控手段保证主干道关键节点处公交畅通,弹性化运行公交专用道的时段及位置,并以基于车路协同的移动违法抓拍系统为保障,提升公交系统运行效率,平衡社会车辆和公交车辆的利益。

With the gradual increase of car ownership,the operational effectiveness of bus lane is limited and under expectation.How to support the effective operation of bus lane becomes a key to removing the obstacle for implementing bus priority.This study summarizes the causes for the effectiveness reduction of bus-only operation,and then proposes that,the cluster-patterned metropolitan area of Chongqing,divided by mountains and rivers,should support the bus-only system with the following strategies to improve the bus priority system and balance the tradeoff between bus and car.First,guarantee the right-of-way of bus at the key nodes along the arterials with implementation of intelligent traffic signal control.Then,perform the operation of bus lane with elastic durations and segments.Finally,implement the V2X-based vehicle-mounted electronic police system for car surveillance to support the two strategies above.
