Research Of Intelligent Transportation System And Key Technology

The sharp national economic developments has propelled the course of urbanization and motorization, in addition the construction of roads cannot catch up with the abrupt increase of vehicle amounts, thus the traffic problem is made salient anu becomes one of the main hindrances of economic sustainable development.This paper subjects on the national intelligent transportation system. It constructs the research work on the basis of a survey on domestic and alien intelligent transportation systems, and pays special heeds on the theory of integration in system engineering, The main jobs of this paper are as follows:1 It compares the systematic structure of intelligent transportation in terms of both macro and micro ways of information collecting modes, and proposes that micro information collecting mode based on microwave short-distance communication is the one suitable to Chinese situation..2 . Moreover this paper constructs a systematic structure of intelligent transportation on the basis of beacon, on which the paper further demonstrates three analysis perspectives, namely the functional, physical, and software systematic structure.3 . It analyzes the ways of realization in infrared short-distance information collecting mode, microwave short-distance information collecting mode, etc based on beacons, through which the paper makes its root on 5.8 GHz microwave short-distance information collecting mode.4 It works out the formula on mobile vehicle numbers based on beacon and integrated with traffic data..5 The paper elaborates finally the designation of operation center in the particular context of Hunan regional vehicle automatic recognition management system.
