Problems solved by technology

These interactive behaviors lead to increased traffic delays for pedestrians and motor vehicles, and even further escalate to human-vehicle traffic accidents when avoidance fails, causing personal casualties and economic losses

Embodiment Construction

[0054] The technical solution adopted by the present invention will be further described below in combination with schematic diagrams.

[0055] The preferred embodiment relates to a pedestrian-specific phase setting method at two-phase signal-controlled intersections. The method is based on human-vehicle interaction behavior. In two-phase signalized intersections, usually right-turning vehicles are not controlled by signals. When pedestrians pass, vehicles turning left will pass at the same time. Pedestrians will continue to interact with turning vehicles during the passage of the green light phase. Each entrance has 3 pedestrian-vehicle interaction areas. Taking the intersection of four entrances as an example, there are a total of 12 human-vehicle interaction areas. For details, see figure 1 . Different types of human-vehicle interaction behaviors will be generated in each human-vehicle interaction area.

[0056] The principles for analyzing human-vehicle interaction behav...

Abstract

The invention provides a special phase setting method for controlling pedestrians at intersections by a two-phase signal. The method determines whether the special pedestrian phase is set at the intersection based on total delay of traffic participants. According to the special phase setting method disclosed by the invention, the pedestrians and motor vehicles can pass through the intersections under the condition that the per capita possession of road space-time resources is relatively fair while the passing efficiency is ensured, so that the efficiency and the fairness of the pedestrians andvehicles passing through the intersections are ensured.

Description

technical field [0001] The invention relates to the field of intelligent transportation systems, in particular to a method for setting special phases for pedestrians at intersections controlled by two-phase signals. Background technique [0002] In recent years, China has advocated motor vehicles to avoid pedestrians, which has changed the conditions for human-vehicle interaction, and the setting conditions for pedestrian-only phases have also changed accordingly. In my country, since the "Road Traffic Safety Law" (hereinafter referred to as the "New Traffic Regulations") was revised on January 1, 2013, turning vehicles must give way to normal pedestrians at intersections. This regulation further ensures the safety of pedestrians at signalized intersections, and also leads to a significant change in the behavior pattern of human-vehicle interaction, which affects the delays when human-vehicle interaction occurs. In some cities, the obedience rate of motor vehicles has not r...
