Method for designing signal intersection of bus lanes

Abstract

The invention relates to a method for designing the signal intersection of bus lanes, comprising the following steps of: 1), firstly determining the traffic capacity of the signal intersection of bus lanes; 2), and then designing the intersection geometric line and the signal time proportion. The method improves the original saturated flow rate method and considers the effect of the saturated vehicle head time interval to the intersection traffic capacity when the bus is mixed with the social car on the bus lane; the method is suitable for calculating the traffic capacity of the signal intersection of bus lanes; the method fully considers the effect of the saturated vehicle head time interval to the intersection traffic capacity when the bus is mixed with the social car on the bus lane, can determine the corresponding intersection traffic capacity according to the special traffic of the intersection, and can more actually reflect the feature condition of the traffic capacity at the intersection; and the method has relatively higher reliability.

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 the traffic capacity method of signalized intersections based on the saturated flow rate method and considers the influence of bus-only lanes in the geometric line optimization and signal timing design methods of signalized intersections with bus-only lanes. Setting up the geometric line type and signal timing of signalized intersections for bus-only lanes 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. Background technique [0002] The traffic capacity of a signalized inte...

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, little research has been done on the impact of bus lanes on intersection capacity, which cannot meet the needs of geometric line design and signal timing of signalized intersections with bus lanes
