The study of urban shared bike travel characteristics is the premise of sustainable development of shared bike. In this paper, using the form of a questionnaire, the citizens of Fucheng District of Mianyang City were investigated and obtained 98 Valid data. Analysis of travel characteristics is based on survey data, and stud ies the factors affecting the use of shared bicycles, combined with the establishment of travel behavior theory Logit model, with the aid of SPSS Calculate with software. The results showed that women were more likely to choose shared bike trips than men; those who chose shared bikes tended to be younger; those who shared bikes were more favored by students and office workers; those with higher education levels were more likely to choose shared bike trips; and those with higher education levels were the most significantly affected.
As one of the “new four great inventions” in China, shared bicycle has aroused extensive attention of many scholars at home and abroad (Wei, Mo, & Liu, 2018). This paper analyzes the problems of shared bicycle parking, deposit safety and vehicle maintenance, and puts forward concrete solutions from different angles (Wang, Yu, & Dun, 2018). This paper studies the optimal scheduling problem of shared bicycle, analyzes the factors affecting the demand of shared bicycle, and proposes an optimal scheduling scheme based on multi-objective programming (Yu, 2018). Using analytic hierarchy process to screen out the index which has a greater impact on the demand of shared bicycle LM Neural network gets the weight of each index, and gives reasonable suggestions for the forecast of shared bicycle demand (Wang, 2018). Based on the location information of shared bikes and other data, visually revealed the laws of residents’ travel hotspots and spatial and temporal characteristics (Wang, Li, Xu, Ma, & Wei, 2018). Considering the age distribution, the market demand model of shared bikes was established, and the release model of shared bikes was established by Markov chain to determine the number of release points of Shared bikes (Gan, Zhang, Huang, & Hu, 2018). Aiming at the shortage of shared bicycle intelligent parking points in rush hour, a parking point assignment algorithm based on improved genetic algorithm is proposed (Shi, Chen, & Xu, 2019). Based on the analytic hierarchy process (AHP), this paper studies the influence and development of shared bicycle and shared car on urban traffic (Wang, 2019). An ARIMA model was proposed to predict the bicycle demand and status at the station by analyzing the number of bicycles and local population movement data in the Barcelona community (Kaltenbrunner, Meza, Grivolla, et al., 2010). The linear regression model was used to forecast the demand of bicycle in New York City (Singhvi, Singhvi, Frazier, et al., 2015). Based on the historical data of Zhongshan public bicycle system, the influence of scenic spots on travel demand and the ratio of site demand to supply are studied by using multiple linear regression model (Zhou, Wang, Zhong, et al., 2018). The proposal is based on MART Regression and Lasso. The final destination and vehicle duration were predicted by two regression models. Summarizing the literatures, it is found that domestic and foreign scholars pay more attention to the sharing of bicycle policy, the status quo, demand, the number of drop points and optimal dispatching, and lack of exploration of the characteristics of riders (Zhang, Pan, Li, et al., 2016).
Therefore, this paper will study the characteristics of shared bicycle travel from the perspective of traffic planning, in order to analyze the factors affecting the development of shared bicycle. Based on the travel behavior theory, a binomial choice of shared bicycle travel was established Logit based on the survey data, the model parameters were calibrated to determine the significant factors affecting the shared bicycle travel decision.
urbanization rate 77.71% male to female sex ratio 1:1, 60 near the mouth of the elderly over the age of 150,000 people. Large-scale commerce, residential areas, health institutions, schools and other facilities in the region are relatively complete. However, the public transport system in the study area is still not perfect, there are few bus lines, the phenomenon of shared bicycles, and the lack of systematic planning of bicycle lane system. The research on the characteristics of shared bicycle travel is the basis of reasonable launch of shared bicycle and scientific planning of non-motorized road, which can effectively solve urban traffic problems.
Based on the collection of field survey questionnaire, a total of 98 valid data on the use of shared bicycles were obtained from Fucheng District of Mianyang City. The questionnaire contained two types of information: personal characteristics and travel characteristics. Personal characteristics included whether to use shared bicycles, gender, age, education level, occupation type, travel characteristics including riding hot spots, travel purpose, riding duration, frequency of use, and expected drop point. The contents of the questionnaire are shown in
As can be seen from the analysis of the returned questionnaire, i.e. 98 According to gender, among the survey subjects: 45 Male position, 53 Female gender ratio is similar 1:1 (see

Fucheng District of Mianyang City is high 78%, However, there are still a few people who do not choose to use shared bicycles (see
The logit model is a discrete choice model based on utility maximization. This model is quick to solve, and can not only predict in the sample, but also accurately predict the data out of sample. The logit model assumes that the random terms of the utility function are independent of each other and follow the same Gumbel distribution. The main theoretical basis of Logit model is the theory of utility maximization. Random utility theory is the assumption that the traveler is the basic unit of traffic behavior and decision-making, and the traveler always chooses the option with the greatest perceived utility (Jalina, Li Feng., 2017).
The conditions for the traveler n to choose scheme i are as follows
u i n > u j n , i ≠ j ; i , j ∈ A n

In: u i n The utility of choosing scheme i for the traveler n; u j n the utility of choosing scheme j for traveler n; A n For a collection of selection schemes.
Utility is a random variable that is assumed to be a function of the following variables: outgoing individuals, choice characteristics, selected environments; which can be expressed as
u i n = v i n + ε i n
where: v i n Fixed term of the utility function for choosing scheme i for traveler n. ε i n Choose the random term of the utility function of scheme i for the traveler n.
According to the theory of utility maximization, the probability that a walker n chooses scheme i p i n can be expressed as follows
p i n = p r o b ( u i n > u j n , i ≠ j ; i , j ∈ A n ) = p r o b ( v i n + ε i n > v j n + ε j n ) 0 ≤ p i n ≤ 1 , ∑ i ∈ A n n p i n = 1
where: A n For a collection of selection schemes.
The question of “whether to choose a shared bicycle as the mode of travel” is studied by commuters. Only “choose” y = 1 and “do not choose” y = 0. These two dependent variables take values, so the binomial choice model, namely BL model, is selected. For the convenience of parameter estimation and comparison, the utility function of y = 0 is 0 (i.e., the choice limb of the shared bicycle is not selected as the reference choice limb), and the utility function of y = 1 is V ( V = β 0 + β 1 X 1 + β 2 X 2 + ⋯ + β n X n ) .
The probability of y = 1 is
P ( y = 1 ) = exp ( v ) 1 + exp (v)
The probability of y = 0 is
P ( y = 0 ) = 1 1 + exp ( v ) ff
Thus, the model can ultimately be expressed as U = β 0 + β 1 X 1 + β 2 X 2 + ⋯ + β n X n + ε Where β 0 - β n parameter calibration by maximum likelihood and testing its significance are needed.
the development of shared bicycles was developed in the early stage, colleges and universities were selected. Students had earlier exposure to shared bicycles and a wider range. Therefore, the proportion of students who would choose to share bicycles was higher. However, the general education level of employees and public institutions was higher, and they were more likely to accept new things. They also had more access to shared bicycles. The Internet level was also higher, and they preferred to share bicycles.
Binomial selection was established with data from 98 questionnaires Logit whether or not to choose shared bicycle travel as the dependent variable, and whether or not to choose gender, age, education, occupation as the influencing factors for choosing to use shared bicycle.
Based on the survey data and the established model, a binomial logit regression was performed using SPSS software, and the results are shown in
The final model was obtained using SPSS regression with significance less than 0.05, and four variables, namely gender, age, and education, were used as variables in the model. The utility function for the traveler to choose a shared bike can be expressed as U = β 0 + β 1 X 1 + β 2 X 2 + β 3 X 3 + β 4 X 4 According to the calibration results, it is possible to obtain
U = − 1.287 − 0.391 X 1 − 0.240 X 2 + 0.779 X 3 − 0.162 X 4
Controlling for age and education, men were less likely than women to choose sharing bicycles. Women were more likely to choose sharing bicycles. Men were more likely than women to choose faster and shorter travel modes, such as private cars, especially commuting, and men were more likely to arrive at work earlier. Women were more likely to choose more comfortable travel modes. The significance was −0.048, rejecting the null hypothesis that the regression coefficient was 0.
The coefficient of the age variable in the model was estimated to be −0.240, indicating that the older the traveler, the less effective the choice of shared bike, i.e., the less likely the choice of shared bike as a mode of travel. This is also consistent with the actual situation. Sharing a bike requires the use of a mobile phone. Older people are less physically fit and less skilled in the use of smartphones, so they are less likely to use shared bikes than younger people. A significance of 0.037 was used to reject the null hypothesis of a recall coefficient of 0.
The coefficient of educational level in the model was estimated to be 0.779, which showed that the higher the education level of the traveler, the greater the utility of choosing the shared bicycle, that is, the more biased to choose the shared bicycle as the mode of travel. This is also consistent with the actual situation. The group with higher educational level had more opportunity platforms for receiving fresh information; the group with lower educational level did not know the information in time and preferred the choice of traditional transportation.

significance of 0.003 was used to reject the null hypothesis of a recall coefficient of 0.
The coefficient of occupation in the model is −0.162, indicating that students and office workers are more effective than freelancers and self-employed workers in choosing to share bicycles. Students and office workers tend to choose to share bicycles, which is consistent with the actual situation. Among the four variables, the significance values of gender, age, education, and occupation were 0.048, 0.037, 0.003, and 0.044, respectively. The effect of education on the choice of sharing bicycle was the most significant, with a significance value of 0.048 for gender having the least effect.
As a short-distance travel tool, sharing bicycle is mainly used for commuting, entertainment and shopping, and riding hot spots are concentrated in residential and commercial areas, while residents expect to share bicycle in residential and commercial areas, which is consistent with the analysis results of riding hot spots. It is suggested that shared bicycles be mainly put in residential and commercial areas. As a connecting means of transportation, bus stops are also hot spots, and the riding time range is generally 5 - 20 minutes. It can be seen that the shared bicycle parking places cannot be too far apart to stop near the destination, and cannot be too close to each other to cause waste of public space.
According to binary Logit Model building and SPSS, the results show that gender, age, education level and occupation have a significant effect on sharing bicycle travel. Women are more inclined to choose sharing bicycle than men, and age has a negative effect on the effect of sharing bicycle. Educational level has a positive influence on the utility of choosing shared bicycle, which is inseparable from the operation mode of shared bicycle “Internet +” and the characteristics of initiating on campus. The results of this study are of great significance for bike-sharing enterprises to provide the quantity of bikes, delivery stations and urban traffic planning according to the regional population proportion and the distribution of public facilities. At the same time, the reasonable placement of bicycles also provides residents with great convenience.
Because the distribution group of the questionnaire is mainly concentrated in the area with large human flow in Fucheng District of Mianyang City, the area coverage is small, and the amount of collected data is not large and the representativeness is insufficient, the factors affecting the sharing of bicycle travel behavior are not considered comprehensively, therefore, the above conclusions cannot comprehensively reflect the situation of sharing of bicycle travel in China, and there is still further improvement in this paper.
