Based On The Bus Electronic Stop Evaluation System Of Urban Road Traffic Condition Is Studied

With the rapid development of the global economy technology, real-time evaluation of urban road traffic status has become an important research direction in the intelligent transportation management system. According to the public transportation has a high rate of coverage in time and space, collecting real-time information of driving bus can provide a basis of real-time evaluation research to urban road traffic status.This paper first analyses and introduces the evaluation index of urban road traffic status, and study the established of the entire evaluation index system, at the same time, introduces and compares four kinds of traffic status evaluation methods. On this account, ensure the cloud model comprehensive evaluation method is used for evaluating urban road traffic status. The bus electronic station board system is detailed introduced in this topic. In addition, introduces collecting principle and gathering technology and preprocessing methods of bus driving information from the bus electronic station board system, analyses abnormal data repair methods in detail, so that data information which are passed through the data pretreatment process turn to be more complete and the degree of accuracy in evaluating the urban road traffic status turn to be higher. Based on the practical survey data of case analysis, the average speed, crowded coefficient and gradient in that cloud model comprehensive evaluation method are selected to be the evaluation indexes. The paper analyses comprehensive evaluation principle and evaluation calculation process, and ultimately establishes a reasonable accurate urban road traffic status evaluation model.Based on bus driving data information in the bus electronic station board system, using Visual Studio2010and SQL2008database designing platform, the paper finally successful compile a program which can obtain real-time evaluation result from urban road traffic status evaluation system.
