Type Classification of Motorized Vehicles Red Light Running and Their Characteristics Analysis

摘要

In order to study types of motorized vehicles red light running and their characteristics, the concept of critical distance was introduced, combining with the start and end of red light, to classify motorized vehicles red light running into three categories: deliberate and unintentional red light violation at red onset and red light violation at red end. Based on video observation data, the number of motorized vehicles that commit any of the afore-mentioned three types of red light violation was statistically analyzed, and then their characteristics under various traffic control and management conditions were explored using z-test method. The results show that the majority of red light runners at red start are deliberate, while the unintentional red light violators also share some proportion. At the end of red light, there are a few vehicles violating red light as well. Additionally, the rates of red light running are obviously varying between those three classifications of red light running under the conditions of countdown timer, automatic red light camera, green flashing device, different speed limits and peak period.
