Intersection signal timing method capable of converting steering function of lanes within single signal cycle

Abstract

The invention discloses an intersection signal timing method capable of converting the steering function of lanes within a single signal cycle. Firstly, conventional signal phase timing is carried out under the condition that the function of the lanes at an intersection is fixed, and the signal cycle C, a phase time T1,a phase time T2 and a phase time T3 are obtained through calculation. Secondly, under the condition that basic verification is satisfied, by improving the saturability of a through lane at the intersection, the purposes of lowering the saturability of a left-turn lane and transferring the time and space resources of the through lane to the left-turn lane are achieved. Finally, the total signal cycle C is reduced by reducing the phase time T2, optimization circular calculation is carried out, service level evaluation is carried out on the calculation result, and therefore effective usage of the time and space resources of the intersection is achieved, and the single average delay of the intersection is reduced. The intersection signal timing method capable of converting the steering function of the lanes within the single signal cycle can effectively verify whether the existing intersection is adaptive to the traffic technology, and flexible transfer the residual time and space resources of one phase to another phase within the single signal cycle.

Description

technical field [0001] The invention relates to the technical field of road traffic control, in particular to an intersection signal timing method for changing lanes and steering functions within a single signal period. Background technique [0002] In order to make full use of the space-time resources at intersections, the remaining space-time resources of a certain phase in a single signal cycle can be flexibly used in another phase, so as to improve the traffic capacity of road intersections and achieve single traffic without increasing the scale of lanes. The steering function of an entrance lane can be flexibly changed within the signal cycle, and the redundant space-time resources can be transferred to the required place to improve traffic efficiency. The applicant applied for a utility model with the application number 201220519142.5 on October 11, 2012, named "Intersection Traffic System with Lane Change and Steering Function within a Single Signal Cycle" (hereinafte...
