Embodiment Construction

[0009] refer to figure 1 , the specific working principle of this method is introduced as follows.

[0010] Step 1: This method is based on the collection and arrangement of pedestrian traffic accident data and the investigation of pedestrian traffic flow. First of all, the accident responsibility certificates of the traffic police brigade were collected, and the traffic accident liability certificates involving vehicles colliding with pedestrians were screened out, and the data of pedestrian traffic accidents were screened. Accidents, accidents with no pedestrian casualties and only property damage are not recorded; (2) accidents with only driver casualties and the number of people are not recorded; (3) pedestrian traffic accidents that occur on roadways and intersections are recorded; (4 ) Pedestrian traffic accidents in the community, and pedestrian traffic accidents in closed areas such as vegetable markets and driving schools are not included in the research scope; (5) A...

Abstract

The invention discloses a traffic safety research method based on pedestrian traffic behaviors, and the method comprises the steps: 1, enabling an information collection unit to collect pedestrian traffic accident data and the pedestrian traffic flow, and transmitting the data and the flow to a decision-making unit, and enabling the decision-making unit to screen the information, remove useless information, and reserve reliable information with a large reference value; step 2, in a decision-making unit, utilizing the collected pedestrian traffic accident data and the pedestrian traffic flow data obtained by investigation, and utilizing a chi-square goodness of fit test method and a dominance ratio model to research the influence of the pedestrian facing the traffic flow compared with the pedestrian backing on the traffic flow on the pedestrian safety; besides, based on the pedestrian traffic accident data and the pedestrian traffic flow data, researching the safety of pedestrians when crossing the street at intersections of urban roads and highways, road zebra crossings and road sections without zebra crossings by using a variance analysis method, and finally, proposing suggestions for improving the pedestrian traffic safety according to safety analysis results of the pedestrians under different traffic behaviors.

Description

technical field [0001] The invention relates to the field of highway traffic safety, in particular to a traffic safety research method based on pedestrian traffic behavior. Background technique [0002] Pedestrians, as the main group of road users, participate in the road traffic system to a great extent. In my country, there is a mixed traffic mode of vehicles and pedestrians on most roads, and due to the large population of our country and the large demand for traffic travel, the risk of collision accidents between vehicles and pedestrians has increased to a certain extent. Pedestrians on the road are most likely to be injured by collisions with moving vehicles, so traffic accidents involving vehicles hitting pedestrians are a major problem. Among the traffic accidents that occurred across the country in 2019, there were 53,558 traffic accidents in which vehicles collided with pedestrians, 17,473 people were killed, and 45,495 people were injured, accounting for 21.6% and...
