Problems solved by technology

The through bus-only lane reduces the conflict between straight-going buses and social vehicles before the intersection, but for intersections without right-turn special phases, straight-going buses and right-turning social traffic will form conflicts in the intersection

Embodiment Construction

[0029] Below in conjunction with accompanying drawing, the present invention will be further described:

[0030] Since there are many coefficients in the process of calculating the traffic capacity of signalized intersections with through-type bus-only entrance lanes, here is a detailed description of them:

[0031] A. Data survey on the calculation method of traffic capacity at signalized intersections with through-type bus-only entrances

[0032] Through the field investigation of signalized intersections with through-type bus-only entrance lanes, the coefficients required for the calculation of traffic capacity are obtained, and the investigation needs to meet the time period requirements:

[0033] a. Data that can be obtained directly from field surveys

[0034] Including entrance lane slope G, intersection signal period length T, lane width K, effective green light time g in the entrance direction e , right turn green light time g r , the ratio of the time of going str...

Abstract

The invention relates to a design method of a signal intersection provided with a straight-through type bus special entrance lane, comprising the following steps of: (a) firstly determining the traffic capacity of the signal intersection provided with the straight-through type bus special entrance lane; and (b) then designing the geometric linetype and the signal timing of the signal intersection. The design method is used for considering the traffic capacity of the signal intersection influenced by the straight-through type bus special entrance lane and can also be used for evaluating and optimizing the geometric linearity of the signal intersection provided with the straight-through type bus special entrance lane.

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. In this method, in the geometric line optimization and signal timing design method of signalized intersections with through-type bus-only entrances, the method based on the saturated flow rate method is introduced to the traffic at signalized intersections considering the impact of through-type bus-only entrances. The capability method is used to optimize the geometry and signal timing of signalized intersections for through-type 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....
