Traffic control method facilitating signalized intersection skew-crossing of pedestrians

Abstract

The invention discloses a traffic control method facilitating signalized intersection skew-crossing of pedestrians. The method comprises the steps of 1, numbering all pedestrian stopping areas and pedestrian crossings at an intersection according to a certain rule; 2, judging whether the requirement of pedestrian skew-crossing in a certain direction exists at the intersection or not; 3, if the requirement of pedestrian skew-crossing in a certain direction exists at the intersection, adopting a strategy combining the phase sequence setting meeting the requirement of crossing in a certain direction and the crossing mode, otherwise, adopting a pedestrian crossing scheme under the predetermined phase sequence setting condition; 4, setting indication identification for inducing the pedestrians to cross the signalized intersection in a skew mode to direct the pedestrians to cross a street. By means of the method, crossing delay of the pedestrians can be reduced, crossing passage efficiency of the pedestrians is improved, the crossing violation rate of the pedestrians is lowered to a certain extent, and potential safety hazards in pedestrian crossing can be eliminated as much as possible.

Description

technical field [0001] The invention relates to the field of traffic management and control, in particular to a traffic control method for pedestrians to cross a signal intersection obliquely. Background technique [0002] Due to the influence of factors such as urban functional areas and infrastructure layout, the actual crossing demand of pedestrians obliquely crossing signalized intersections is becoming more and more obvious. How to optimize the phase sequence setting of signalized intersections and design the crossing The organization strategy and optimization scheme of the pedestrian crossing at the entrance have important practical significance. [0003] At present, there are few optimization design and delay analysis of pedestrian crossing signalized intersections at home and abroad. The convenience of continuous pedestrian crossing is insufficiently considered, and the integrated design of phase sequence setting and pedestrian crossing organization of signalized int...

Problems solved by technology

Such design deficiencies and defects will lead to: 1) pedestrian crossing delay increases, and the corresponding travel time cost increases; 2) due to the increased waiting time for pedestrians crossing the street, pedestrians may be induced to cross the street illegally, resulting in hidden dangers to traffic safety at intersections; 3) Due to the lack of directional guidance for crossing the street, the order of pedestrian queues in the parking area is chaotic, and the efficiency of pedestrian crossing diagonally across the intersection is low
