Research On Evaluation Of Road Traffic Operations Based On Floating Car For Shenzhen

With the modernization of cities, traffic congestion has been becoming an insurmountable problem in the development of cities. In the situation of that, quantize and evaluate the city traffic reasonably and apply this method in the formulating traffic plan, evaluating the measures that ease traffic congestion and guiding citizens travel reasonably have become a hot issue among urban traffic planning designers. And make it own contribution to the sustainable development and promoting social harmony.meanwhile the development of modern space information technology also make it possible to evaluate the situation of traffic fastly and timely.In our country, with the development of economy, the situation of urban traffic is change rapidly. Considering the different space structures between cities, it is different to copy the traffic evaluate system of other city. Here, with the increasing of vehicle possessing, traffic has become heavier and heavier in time and regions. With the situation of this, it is important for urban traffic planning designers to formulate an algorithm and a system, which can evaluate the situation and publish to public.In this project, It mainly consider the scientificalness and practicability and try to formulate and build an algorithm and a system which fit the situation of ShenZhen. And present a solution which contains data acquisition, data transportation, data calculation and announcement.(1) The research of indicator system and algorithmOn the basic of the researching of traffic object, evaluate scale and evaluate algorithm, contrapose the need of ShenZhen traffic control and serve combination the feature of urban traffic and the development of smart traffic, build the ShenZhen traffic evaluation and indication system to evaluate the traffic congestion in Shenzhen. Meanwhile raise the conception of time-based comprehensive traffic indication. Build a model based on distant, time and traffic indication and raise a new algorithm for traffic indication.(2) System development and publish of evaluationIn order to build a application system, here, we build the algorithm for traffic indicator and publish system, which contain the function of data receive, data processing, indicator calculation and website publish. With the help of this system, citizens can get the traffic information immediately. While policy maker can have an assisted assessment of road planning, building and efficiency evaluation.In this paper the structure is as below:The first section is the introduction. The introduction mainly introduce the oriental of the research project, the research background and the oversea and domestic research status and summarize the main idea in this paper.The second section is the study of traffic evaluation system. On the basic of the researching of traffic object, evaluate scale and evaluate algorithm, analysis need of traffic and discuss the need from different group and the indicator of traffic evaluation.The third section is the study of traffic evaluation indicator model, which is based on the traffic evaluation indicator system. In this section we also discuss the research of the algorithm of evaluation indicator and reliability demonstration.The fourth section is the introduction of system and its application. According to the evaluation indication and model, here. It develops the algorithm of traffic evaluation indicator and publish system, which including the design of the system, logic structure, processing and the case about the system and its publish.The fifth section is the conclusion and perspective. In this section It do a summarize about this paper and present the problem needed further studied.
