The Effects Of Bike-sharing On Slow Traffic Violation Behavior

The emergence of bike-sharing has significantly increased the number of non-motorized vehicles in urban dwellings,and has a new impact on the behavior and safety of slow-moving traffic.Therefore,it is necessary to analyze and explore the characteristics of the cross-carriage before and after the occurrence of bike-sharing and its influencing factors,reveal the impact of the emergence of bike-sharing,provide theoretical policies for the management of bike-sharing in China,and provide scientific basis for the management of enterprises.Based on the above objectives,based on field research and behavioral modeling,the author investigates the violations and waiting time influencing factors of pedestrians and non-motorized riders after the occurrence of bike-sharing,and compares them with the slow traffic behavior before the occurrence of bike-sharing.The main works are as follows:(1)Sample distribution,violation rate and waiting time comparison before and after the emergence of shared bicycles.The results show that after the emergence of shared bicycles,the bicycle traffic(including shared bicycles)increased by 213.9%,of which the share bicycle traffic accounted for 58.9%of bicycles,while the share of electric bicycles decreased.Compared with before the emergence of shared bicycle,the violation rate of pedestrians and non-motorized vehicles decreased significantly after the emergence of shared bicycle.Among them,after the emergence of shared bicycle,the active violation rate of pedestrians and non-motor vehicles decreased by about 20%,while the compliance violation rate increased slightly(5-12%).(2)Modeling and analysis of irregularities before and after the emergence of shared bicycles.Comparing the differences of pedestrian,bicycle and electric vehicle violations before and after the emergence of shared bicycle,Logistic model results show that:before the emergence of shared bicycle,the violations of private bicycle,electric bicycle and pedestrian are mainly affected by age and waiting time;after the emergence of shared bicycle,generally speaking,due to the increase of the total number of non-motor vehicle trips,slow traffic violations occur.The influence of other people’s crossing behavior is more significant.Specifically,after the emergence of shared bicycles,private bicycle violations are affected by age,the number of non-motorized vehicles in front,waiting time and vehicle flow.The violations of shared bicycles are affected by age,gender,the number of non-motorized vehicles in front and the flow of motor vehicles.The violations of electric bicycles are related to age,the number of non-motorized vehicles in front and the flow of motor vehicles.Behavior is related to gender,the number of non-motor vehicles in front and the flow of motor vehicles.(3)Modeling and analysis of waiting time before and after the emergence of shared bicycles.Based on Cox regression model of survival analysis,the sample of pedestrians and non-motorized vehicles before and after the emergence of shared bicycles were selected respectively,and the influencing factors model of waiting time was constructed.The results show that the probability of violation of traffic rules increases with the increase of waiting time.Before the emergence of shared bicycle,the significant influencing factors of pedestrian waiting tolerance time and violation riskare age and whether there is a car before crossing,bicycle significant influencing factors are whether there is a vehicle and motor vehicle flow before crossing,and electric vehicle significant influencing factors are the number of non-motor vehicles and motor vehicle flow in waiting area.After the emergence of shared bicycle,in general,waiting tolerance and violation risk of slow traffic are more significantly affected by other people’s crossing behavior.Specifically,the significant influencing factors of pedestrian waiting tolerance time and violation risk after the emergence of shared bicycle are gender,age and the number of non-motorized vehicles in waiting area.The significant influencing factors of private bicycle are gender.The significant influencing factors of shared bicycle are whether there are vehicles before crossing,the number of non-motorized vehicles in waiting area and the flow of motor vehicles.
