Embodiment

[0028] Example: such as figure 1 As shown, an intelligent transportation system based on automobile electronic identification technology includes automobile electronic identification 1, data acquisition unit 2, data processing unit 3 and data application unit 4.

[0029] The automobile electronic identification 1 is correspondingly mounted on the vehicle. The automobile electronic identification 1 stores automobile electronic identification data of the automobile identity and characteristics. These automobile electronic identification data include chip identifiers, vehicle registration information, encoding information, security information, and user information. And vehicle location positioning information and other content. Automotive electronic identification 1 realizes classified collection, precise collection, mass collection, and dynamic collection of vehicle traffic information. Specifically, the automobile electronic identification 1 includes an RFID tag, which has a glob...

Abstract

The invention discloses a road state analysis method based on the automobile electronic identification technology. The method comprises a data collection step, a road section average travel speed calculation step, a road congestion state determination step, a road section average travel time calculation step, a road traffic volume calculation step, a road traffic density calculation step, a road load degree calculation step and a vehicle average delay time calculation step. The method is advantaged in that the method is more economical, more effective, with higher coverage and realizes more comprehensive information collection, more effective support is provided for refined planning and management of urban transportation, through mining calculation and analysis, road state analysis and prediction, traffic service capability evaluation and transportation industry management assistance decision making functions are achieved, advantages of low cost and easy operation are further achieved,and the method is sustainable, dynamic, quantifiable and reproducible.

Description

Technical field [0001] The present invention relates to the fields of driving, traffic management and the like, and is specifically a road state analysis method based on automobile electronic identification technology. Background technique [0002] Traffic information collection refers to the process of acquiring dynamic and static traffic information in the transportation system using various detection techniques. Since static traffic information is relatively stable, it will generally not change in a short period of time. Due to the influence of various external factors, the dynamic information has the characteristics of random changes in the traffic state, which makes the processing and distribution of traffic information a major difficulty. Road traffic information is usually collected through two traffic detection methods: one is a fixed-point detector, and the other is a mobile detector. On the one hand, fixed-point detectors such as coils and video are used to measure th...
