Bus IC Card Traffic Analysis And Public Transport Network Optimization Research Based On Satellite Positioning Technology

The state carries out the city public transport priority development strategy, improve the city public transport service levels, meet the people’s basic travel demand, ease city traffic congestion and pressure on resources and the environment. Chongqing is one of the important center cities in China, the comprehensive transportation hub in southwest area. City area of 82400 square kilometers, the urban core functions of the district resident population of 4900700 people, the city function development area resident population of 3184600 people, iscurrently the administrative jurisdiction China largest, most populous administrative unit, mostwestern economy, the largest total oversize city. With the rapid economic development in recent years, people’s travel demand is increasing,Chongqing motor vehicle retains the quantity is more rapid growth to 20%-30% annual rate of about. By the end of 2013, motor vehicle development zone urban function core area and urban functionretains the quantity already exceeded 900000 units, the average daily new motor vehicles to 380 vehicles, city traffic congestion problems become apparent. Facing serious transportation problemsin Chongqing City, City Hall, traffic committee put development of the public transport system as apriority among priorities, vigorously in the construction of infrastructure construction and improvement.Chongqing public transport group carries the conventional public transport services to expand thearea for the urban function and urban function of the core area of responsibility. By the end of 2013,the total number of Chongqing city bus routes 495,8627 of the total number of vehicles operating vehicles, conventional bus 2013 operation mileage of 862300000 kilometers, passenger volume of 1926920000 person time, average daily passenger capacity of 5300000 passengers. How to solve the problem of how widespread the city bus lines repeated coefficient is high, how to train station express, design class density, both to ensure people travel and convenient, but also to ensure thatthe operation cost of public transport enterprises to save, the best matching of passenger flow andtransportation capacity, long-term study is the bus at all levels of management subject,Production is the core work of public transportation enterprise management, investigation and analysis of passenger flow is the basis of working production. The traditional passenger flow surveymethod is generally rely on manual survey on vehicle, station survey, a random questionnaire survey, understand the origin destination, passenger transfer points, travel time, transfer time, after a week or longer, the survey data back, then the relevant information manually into the computer,the passenger flow analysis. This method is time-consuming and laborious, has not adapted to the urban development and transit enterprises production need to change.With the rapid development of information network technology, bus companies have generally adopted the IC card technology, satellite positioning technology, and relying on wireless, wired network, and realize intelligent scheduling of production, can grasp the vehicle speed, vehicle distance, also can analyze the IC card passengers boarding time, site, the number of statistics.The content of this paper is the implementation of a POS terminal device and IC card on-lineoperation of satellite positioning, access to the IC card passengers boarding time, site, analysis of passenger travel rules, IC card POS machine terminal time only. The realization of the two scaleapplication, at present in Chongqing public transportation group has been extended more than 1000car. Three is the passenger flow analysis technology has been used widely applied to Chongqing each bus enterprises to optimize the production plan and scheduling scheduling, obtained certain result.
