Research On Passenger Flow Measurement Method Of Urban Bus Station Based On Bus IC Card Data

The problem of urban traffic congestion is a hot topic of concern to all sectors of society,and it is also an important issue that cannot be ignored in urban public transportation planning.With the increase in the number of private cars in recent years,the traffic congestion problem is extremely serious.Improve the sharing rate of public transportation in the main city,and vigorously support residents to take public transportation to help alleviate urban traffic congestion.Therefore,the development of public transportation systems has become the only way for many cities to ease traffic pressure.Due to the lack of data,traditional bus operation management relies mainly on the personal experience of managers,so that the bus supply is difficult to meet the dynamic changes in actual demand.Repeated,continuous,and systematic investigations are also difficult to achieve through traditional questionnaire methods.Therefore,this paper takes the bus IC card data as the research object,and mines the information contained in the IC card data to establish a model algorithm to analyze the bus passenger flow.In order to accurately obtain the public transportation information of urban residents and provide data support for traditional public transportation planning,this paper analyzes the current situation of urban public transportation development at home and abroad,and fully studies the data structure and data analysis process of public transportation IC card.The card database performs data extraction and processing,obtains the actual required data fields,performs cluster analysis through the sorted IC card data to obtain the intermediate value of the credit card time record,and uses the IC card data to establish with the bus station scheduling information and the bus GPS data respectively.Contact,through the database query function to match the time to determine the passenger's boarding position.The passenger trip probability is judged by the two methods of the passenger travel chain and the bus passenger travel behavior probability model.The model is modified based on the three factors of station attraction intensity,land use property and transfer coefficient based on the passenger travel behavior probability model method.And get the OD of the entire line passengers.Combined with the example,the travel characteristics of the passengers in Harbin are used to calculate the transfer threshold of the bus passengers,so as to judge the passenger's transfer behavior,and analyze the passenger flow characteristics of the bus through the OD quantity and the passenger flow rate of the boarding and unloading station,and operate the bus for the bus.Management provides data support and reference.
