Design method for setting signal intersection of staggered approach dedicated for bus

Abstract

The invention provides a design method for signalized intersection of setting staggered bus-only approach. The method comprises the following steps of: a) determining traffic capacity of a signal intersection for setting public transportation lane, and b) designing geometric shape and signal timing of the intersection. By the method provided in the invention, the influence of interaction between buses and social vehicles to the traffic capacity is taken into consideration fully; the traffic capacity of the corresponding intersection can be determined according to the specific traffic condition of the intersection; the character condition of the traffic capacity of the intersection can be reflected more truly; and the reliability is relatively high.

Description

technical field [0001] In the design of signalized intersections, intersection geometry design and signal timing are extremely important components, and intersection capacity calculation is an important basis for geometry design and signal timing. With the promotion of bus-only lanes, the impact of bus-only lanes on intersection capacity cannot be ignored. This method introduces traffic at signalized intersections based on the saturated flow rate method and considers the influence of staggered bus-only entrances in the geometric line optimization and signal timing design methods of signalized intersections with staggered bus-only entrances. The capability method is used to optimize the geometry and signal timing of signalized intersections for staggered bus-only entrances. It provides a basis for traffic engineers to carry out traffic planning and management scientifically and rationally, and belongs to the field of traffic planning and management.

Problems solved by technology

Relevant research abroad mainly focuses on determining the equivalent car conversion coefficients of various types of vehicles, thereby reflecting the impact of buses on the traffic capacity of signalized intersections; domestic research focuses on model correction and the traffic capacity of stops at signalized intersections However, there are few studies on the influence of bus-only lanes on intersection capacity, which cannot meet the needs of geometric line design and signal timing of signalized intersections with staggered bus-only entrance lanes
