Abstract: In order to study the impact of non-motor vehicle violations on motor vehicle traffic efficiency at signalized intersections, the non-motor vehicle traffic behaviors are analyzed. An actual intersection is selected as study object, the main violation behaviors of on selected intersection are analyzed by using the linear regression model. For traffic light violation behavior of non-motor vehicles, the violation rate is modeled by using logistic model, and the results are analyzed. At the signal controlled intersection, non-motor vehicle violations affect the normal motor vehicles, and time is delayed. The delay time of motor vehicle under non-motor vehicle violations is modeled, based on the existing violation rate, the delay time of motor vehicle under different violation rate is analyzed. It can been see that the larger the violation rate value, the longer the delay time of motor vehicle will be. For the impact of non-motor vehicle violations on motor vehicles, some improvement suggestions in road design are provided, and public awareness of laws and regulations is strengthened.

Key words: violation behavior, non-motor vehicle, linear regression model, operation efficiency
