The Study On Chongqing Intelligent Transportation System Facilities Constructing Technical Specification

At present the theory and the method of Intelligent Transportation System (ITS) is not very complete and comprehensive. There is not specification about guiding intelligent traffic projects facility constructing,so ITS projects's function and parameter do not suit the actual situation,.The ITS projects's facility,function is too good to suiting the actual situation;or the low rank ITS projects's facility,function do not suit the actual situation,what all results in a mass of waste,To solve this problem, this paper proposes building Chongqing City Intelligent Transportation System Facilities Constructing Technical Specification, and partitioning ITS into three rank depending on ITS facilities and ITS functions according to traffic demand,And this paper also provides the method of partitioning ITS and the detail function,parameter of each ITS rank.This paper first chapter introduces the application,technology of intelligent transportation facilities for referencing traffic planning .It discusses how to choose the traffic key parameters from the traffic parameters at the basis on the reflecting current traffic conditions in Chapter two.It solves how to choose ITS project by fuzzy analytic hierarchy based on the key parameters in Chapter three.It provides how to select ITS project class in Chapter four.At last,it put forwards partitioning ITS into three ranks depending on ITS facilities and ITS functions in ITS projects by analysing lots of data.And, it also provides the detail information of ITS project for each rank.This papar is about Traffic Information Collection System,Dynamic Traffic Information Distribution System,Traffic Monitoring System,Traffic Incident Detection System,Traffic Forecasting System,Traffic Control System,Traffic Guidance System.By researching Chongqing City Intelligent Transportation System Facilities Constructing Technical Specification, the paper puts forward the specification and requirment for ITS project constructing.The research solves how to construct ITS facilities in process of ITS construct. Reducing the cost, speeding up the intelligent transportation construct, improving the traffic control level, and catabaticing traffic jam will come true.
