多岔路口交通秩序管理优化对策

Optimization Countermeasures for Traffic Order Management at Multi-fork Intersections

摘要:

随着城市路网体系的发展变化及交通流量的快速增长，遗留的多岔路口易成为城市交通管理的堵点、乱点。为改善多岔路口的交通秩序、提高通行能力，基于驾驶员行车状态下的视角范围，分别提出了交安设施的优化方法、化繁为简的工程改造对策。近期不具备土建改造条件的多岔路口，可以通过增设地面文字标记、优化标志版面设计、调整信号管控模式等方式提升路径指引服务；具备调整为常规路口条件的节点，可以通过削减相交道路数量、弱化相交道路功能、调整相交道路线型、精细化路口设计的方式，实现交通组织问题的优化与根治。

Abstract:

With the development and change of the urban road network system and the rapid growth of traffic flow, the remained multi-fork intersections are easy to become the congestion and chaos points of urban traffic management. In order to improve the traffic order and improve the traffic capacity of multi-fork intersection, the optimization method of traffic safety facilities and the engineering reconstruction countermeasure to simplify the complexity are put forward respectively based on the driver's field of view in the driving state. For multi-fork intersections that do not have the conditions for civil engineering reconstruction recently, the path guidance service can be improved by adding ground text marks, optimizing the design of the sign layout, and adjusting the signal control mode. Nodes that meet the conditions to be adjusted to regular intersections can achieve the optimization and radical solution of traffic organization problems by reducing the number of intersecting roads, weakening the functions of intersecting roads, adjusting the alignment of intersecting roads, and refining the design of intersections.
