The Travel Characteristics And Spectral Analysis Of Bus Passengers

In recent years,with the continuous growth of China's national economy,the gradual improvement of the level of motorization,urban private car ownership has also increased significantly.With the increasing pressure of urban traffic and environment,the development of public transport is an important measure to solve the problem of urban traffic in recent years.In order to develop public transport,improve the level of service and share o f public transport,it is necessary to understand the characteristics of urban public transport passengers,analyze the mode of bus passenger travel,and grasp the characteristics of passenger transport.Analysis of travel characteristics of passengers,first of all we need to get the travel datas of bus passengers.The traditional bus investigation method is very difficult to ge t the real-time,comprehensive bus travel datas,and with the development of intelligent transportation system is becoming more and more mature,IC card automatic charging system and vehicle GPS system is widely used in many domestic city,and it provides comprehensive and accurate data support for the analysis of travel characteristics of bus passengers.There are problems with missing datas in Public traffic information system Such as a ticket bus system billing system is missing passengers on the site,get off the station,get off time and transfer site records.So this paper carries on the research on the passenger trajectory co nstruction,And try to analysis the bus passenger travel characteristics basis on travel trajectory.This paper first introduces the static data of IC card data,GPS data and bus lines of one bus system,analysis of bus data problems,And preprocess the bus data to solve the data errors,inconsistent format,bus IC card system and GPS system between the two time is not uniform and so on,finally build bus trip trajectory of the passenger above allThe methods of Application data fusion,which proposed methods based on matching of passengers get on site to determine.Based on a single card passengers,taking into account the passengers the continuity and regularity of multi-day trips,we come up with four assumptions,and get off and establish site judgment model to inference transit passengers get off the site,finally according to the manual with survey data,test the passengers on and off the site the results accuracy.Inferred passengers up and down the station on the basis the transfer of passengers from the perspective of both time and space analysis,a method of bus transfer identification based on six factors such as direct coefficient and detour coefficient.Finally the method example,and compare to the time point of recognition methods found that the more comprehensiveIn passenger travel trajectory after the building is completed,extraction of urban passengers travel for three months(OTD)data.From different particle size on the stud y of urban public transport passenger flow for temporal and spatia l statistical analysis,showed in the form of maps,analysis the various features of transit.Finally in a visual way to show the urban public transport passenger flow at the bus station,the public transportation network of distribution,as well as the city's regional distribution of OD,which provides the basis for transit planning and operations.the paper established the fine operation strategy of public transport on the basis of the subdivision of the public transport market,and provides the basis for the improvement of the level of public transport service and the share of public transport.
