The Study Of Overall Bus Comfort And Its Impact On Modal Split

As the economic growth of China, the existing level of public transportation service cannot satisfy the increasing public demand. As an important part of urban public transportation, it plays a significant role to improve the quality of people’s travelling, the urban public transport service and the happiness of citizen. In this paper, the interest will chiefly be laid in how to improve bus comfort so that it can attract more people to regard buses as their first choice when they want to go out, This paper provides a comprehensive review of the different ways to predict the bus comfort, in addition to the variable experimental techniques used. It was found some environment parameters like noise, vibration, thermal comfort and the acceleration would affect the passengers’ experience. By comparing the subjective views of bus passengers to objective physical parameters, a combined bus comfort model was established. At last, using a discrete choice modeling approach, it proves that better OBC standard could improve the modal split in Chinese cities. The main content of this paper are as follows:(1)This paper provides a comprehensive review of some kinds of traffic mode in current and summarizes the advantages and disadvantages of them. It found that the interest will chiefly be laid in how to improve bus comfort if we want it solve traffic problem.(2) In the overall bus comfort model, both the measurement of objective physical parameters and subjective questionnaire survey were conducted to gather the practical environment date, as well as to distribute questionnaires on board city buses during the same trips. By comparing the subjective views of bus passengers to objective physical parameters, a combined bus comfort model was established.(3)An effective approach integrated the comfort model, measuring instrument and the driver monitor was established to calculate the concrete value of passengers’ perceived bus comfort.A. Hardware design: The design of S3C2440A, memory unit,3.5inch LCD, temperature and humidity sensor SHT11、 audio card UDA1341TS、acceleration sensor ADXL345, power unit.B. Software design:The porting, configuration, compiling of Boot Loader and Linux kernel; Make a file system which could support QT; The design of GUI.(4) It attempts to identify factors that influence modal split for journeys, using a discrete choice modeling approach to calculate the modal split. It proves that the better OBC standard could improve the modal split in Chinese cities.
