Problems solved by technology

However, due to the large difference in the travel characteristics of non-motor vehicles and motor vehicles, the phenomenon of non-motor vehicles encroaching on motor vehicle lanes is serious, and the unified scheduling with motor vehicles leads to greater conflicts between motor vehicles and non-motor vehicles. Therefore, non-motor vehicles are analyzed separately and set Appropriate stop line position and appropriate non-motor vehicle early stage in signal control are of vital significance to comprehensively improve intersection traffic capacity and reduce residents' travel time

Embodiment Construction

[0035] The present invention is described further below, and the two-phase intersection non-motor vehicle advances the parking line setting method and comprises the steps:

[0036] 1) Collect the initial signal timing information, road geometry information, traffic flow information and operation information of the intersection signal lights for urban intersections:

[0037] On the road section where the machine is not mixed and the mutual influence is serious, the signal timing status (including cycle duration, phase number, green light time, yellow light time and green light interval time of each phase) and geometric conditions ( Intersection area, length, number of road lanes) real-time monitoring and recording traffic flow information (mainly motor vehicle, non-motor vehicle flow). In this patent example intersection, the initial signal timing information, road information, and traffic flow information can be obtained by field surveys and can also be collected by camera met...

Abstract

The invention discloses a method for arranging a non-motor vehicle stop-in-advance line at a two-phase signal-controlled intersection. According to the method for arranging the non-motor vehicle stop-in-advance line at the two-phase signal-controlled intersection, the feasibility of the arrangement of the stop-in-advance line is judged primarily by inputting the actual geometrical characteristic of the intersection, the flow of motor vehicles and the flow of non-motor according to the characteristics such as the time for the motor vehicles to catch up the non-motor vehicles; a decision rule is set according to the target that the traffic capacity at the intersection is maximized, the fact whether it is suitable to arrange the stop-in-advance line at the intersection is judged through calculation, and the distance between the stop-in-advance line and the intersection and the feasibility that the signals are trigged in advance are calculated; a stop line at the position of an entrance lane of the intersection is re-designed according to the characteristic information of the two-phase intersection, and thus optimization of the motor vehicle and not-motor vehicle comprehensive traffic capacity is achieved.

Description

technical field [0001] The invention belongs to the field of urban signal control intersection planning and design, and is used for two-phase small-scale intersections where the urban motor vehicle flow rate does not exceed 2500pcu / h and the non-motor vehicle flow rate is not less than 800 vehicles / h. Analysis, combined with the reduction of motor vehicle traffic capacity and the increase of non-motor vehicle traffic capacity, sets the discrimination rules, judges the feasibility of setting non-motor vehicle advance at intersections and the relationship between the length of non-motor vehicle advance and the flow of non-motor vehicles, involving a combination of A method for setting the early stop line for non-motorized vehicles at urban two-phase signal-controlled intersections adjusted by the signal timing scheme. Background technique [0002] As an integral part of the urban traffic system, non-motor vehicles play a very important role in the urban traffic system. Non-mo...
