Judgment method for section pedestrian crossing signal lamp arrangement

Abstract

The invention discloses a judgment method for section pedestrian crossing signal lamp arrangement and belongs to the field of traffic management and traffic safety. The method comprises the steps: relevant information is first acquired from a section, relevant parameters are extracted, a relational expression between section pedestrian crossing signal lamp arrangement basis values and the extracted parameters is built based on a gathering model, corresponding section pedestrian crossing signal lamp basis values W are calculated by assigning combinations of different values of the relevant parameters, and a pedestrian crossing signal lamp threshold W0 is set according to an assigned section; when the basis value W of a corresponding parameter combination of a certain section is greater than the threshold W0, a pedestrian crossing signal lamp needs to be arranged at the section; otherwise, the arrangement is not needed. According to the judgment method, influences of various road characteristics including motor vehicles and pedestrians, traffic flow and traffic environments on the section pedestrian crossing signal lamp arrangement are considered, the judgment time period is favorably shortened, the judgment efficiency and accuracy are improved, and the section passing efficiency and the pedestrian traffic safety are improved.

Description

technical field [0001] The invention relates to a method for determining the setting of pedestrian crossing signal lamps on road sections, and belongs to the fields of road traffic management and traffic safety. Background technique [0002] Pedestrian traffic is the most commonly used mode of short-distance travel, and it is an important part of urban traffic. Compared with motor vehicles and non-motor vehicles, pedestrians are the largest and most irregular part of traffic flow, and they are the weak in traffic activities. When pedestrians and traffic accidents occur, pedestrians are often the victims. In order to improve the safety of pedestrians crossing the street, setting up pedestrian crossing signal lights is one of the important measures to improve road traffic safety and ensure the smooth flow of roads. However, at present, most domestic studies on signal setting focus on motor vehicles, and mostly ignore the traffic needs of pedestrians, resulting in pedestrians ...

Problems solved by technology

[0003] In the past, the setting of pedestrian crossing signal lights on road sections was mainly based on discrete factors. For example, countries such as the United Kingdom, the United States, and Japan have formulated the setting basis based on pedestrian flow, motor vehicle flow, traffic accidents, and the number of gaps that pedestrians can pass through; domestically, it is mainly based on traffic efficiency, Discrete methods such as traffic capacity, traffic delay, pedestrian flow, etc., China's "Road Traffic Signal Light Setting and Installation Specifications" (2006) and "Pedestrian Crossing Signal Light Control Setting Specifications" (2009) proposed based on peak hour traffic, 12-hour traffic, pedestrian traffic The basis for the setting of pedestrian crossing signal lights for peak hour traffic and continuous 8-hour traffic, this method only needs to meet one of the specific factors to consider setting up pedestrian crossing signal lights for road sections; and the setting of pedestrian crossing signal lights for road sections is a problem involving many factors, such as road Conditions, vehicle composition, pedestrian demand, geometric conditions and other factors, relying on experience alone or relying on a single index cannot meet the requirements of urban traffic planning and management. It can significantly improve the efficiency and credibility of the method for judging the setting method of pedestrian crossing signal lights in road sections if it can meet the requirements of safety and diversity, and can reflect the actual road traffic conditions.
