Abstract

The invention discloses a method for judging time accumulation effect of influence of congestion charge canceling on traffic safety. The method comprises the following steps: (1) determining a research area; (2) conducting data acquisition; (3) matching an optimal comparison area; (4) judging the result of the influence of a congestion charge canceling policy on traffic safety; and (5) determiningthe time accumulation effect. According to the method, an area where the policy of canceling congestion charging is implemented is taken as an experimental object, an area where the policy of canceling congestion charging is not implemented is taken as a contrast object, then accident occurrence amounts of the experimental object and the contrast object within a certain period of time are respectively collected, and comparative research based on the proposed method is conducted so as to judge the time accumulation effect of the influence on the traffic safety after canceling the congestion charging policy. Generally, after the policy is canceled, the influence effect on the area does not disappear immediately, a retention effect lasts for a certain time, and the duration of the influenceon regional traffic safety after the congestion charging policy is canceled can be judged more accurately by the method provided by the invention.

Description

technical field

[0001] The invention relates to the technical field of road traffic accident safety, in particular to a method for judging the time cumulative effect of cancellation of congestion charges on traffic safety. Background technique

[0002] In order to reduce road congestion, many countries and regions have begun to implement congestion charging policies, aiming to reduce the number of vehicles entering certain areas during peak hours, improve road operation levels, and reduce the incidence of road accidents. However, the congestion charging policy is not permanently implemented. After changing the travel structure of residents, it will generally be canceled after a certain period of time. Previous studies have believed that after the cancellation of the policy, the impact on the region will disappear immediately. However, after the cancellation of general policies, there will be a cumulative effect for a certain period of time. Contents of the invention [00...
