How Does Bike Sharing Affect Travel Mode Choice Of Commuters

Since 2016,bike sharing has developed rapidly in Beijing.From the perspective of urban traffic structure,the share of other modes of travel has changed after the emergence of bike sharing.The emergence of bike sharing reduces the share of private car travel,increases the share of green traffic,alleviates traffic congestion and exhaust emissions during commuting period.Sexual problems.This paper explores the impact of bike sharing on travel mode choice,and makes an empirical study on the change of travel mode choice share after the emergence of bike sharing and the change of influencing factors of commuters'travel mode choice.This paper collects the data of commuters'travel choice and individual characteristics in Beijing,compares the distribution of commuters'travel mode share with or without bike sharing scenarios,establishes a travel mode choice model with or without bike sharing scenarios,and interprets the factors affecting travel choice in the model.Different from the previous studies,this paper uses micro-simulation method to retrieve the collected sample data and obtain travel choice data based on the overall population characteristics of Beijing.In addition,this paper divides commuters into groups according to travel distance,and subdivides the impact of bike sharings on travel choice under different distances.This paper obtains 7422 commuter choice data and heterogeneous information through declarative preference survey and micro-simulation,compares the distribution of travel mode share in different distance groups with or without bike sharing scenarios,and explores the alternative complementary relationship between bike sharing and other travel modes.93 942 data of Beijing commuters'travel characteristics were captured by Internet big data.In different distance groups,SP data and API data were used to build utility models of commuters' choice of travel modes based on nested logit model and multiple logit model,which were homogeneous(not different because of commuters'individual characteristics)and different.Under qualitative hypothesis,this paper explores the impact of travel time and travel cost on the choice of travel mode,and under heterogeneity hypothesis,explores the significant influence factors of personal characteristics,travel characteristics,regional characteristics and service characteristics.The results show that:firstly,bike sharing has complementary effect on public transport,especially in the medium and long commuting distance,it can substitute for private car in short and long commuting distance.Secondly,the main function of bike sharing is short distance commuting and connecting with public transport,while gender,age,education level,work flexibility,bicycle ownership,residential location,comfort and safety have significant impact on the choice of bike sharing,bike sharing+public transport.Thirdly,after the emergence of bike sharing,the factors affecting the choice of travel modes in full-distance,short-distance and medium-distance commuting change greatly,while the factors affecting the choice of travel modes in long-distance commuting change slightly.Finally,based on the analysis of the relationship between different modes of travel and the factors affecting commuters'choice of modes of travel,this paper puts forward some suggestions for sharing bicycle enterprises to increase the amount of bicycles put into public transport stations,increase the recycling and utilization of bicycles,and increase cooperation and data sharing with bicycle enterprises for public transport enterprises.The suggestion of sharing is to provide subsidies for sharing bicycle enterprises,to publicize urban traffic data and to standardize bicycle travel and parking.
