Embodiment Construction

[0038] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] The evaluation of the real-time road conditions in the intelligent transportation system firstly describes the influence and change of the coverage rate of the urban road system by the amount of different samples selected, the repetition rate of the same unit road section, whether the sample vehicle is on the road, and various state parameters. Re-analysis illustrates the real-time performance of the system when realizing real-time road conditions. Finally, the real-time road condition performance of the GID-based system is compared from the aspects of vehicle load balance on the same road segment and the average driving speed, driving time, fuel consumption, and engine load of vehicles at the same time period and at the same starting point with or without the GID induction system Evaluate.

Abstract

The invention discloses an intelligent traffic solution scheme based on a GID. According to the intelligent traffic solution scheme, a GID terminal is used as a movement speed meter to collect various static and dynamic information such as the speed and the operating state of vehicles, network plate numbers and various positioning technologies are combined, a quick and safe information transmission method depending on an ubiquitous network is used for achieving real-time road condition. According to the technical scheme for solving the technical problems, the achievement of the GID mainly comprises three parts: the first part is a multimode multi-homing and multi-state AP terminal, the second part is the networking mode of the network, the third part is a cloud service platform, and exchange and sharing of the service are conducted. The multimode and multi-homing characteristic of the GID system terminal is achieved through the inherent communication mode and bridging module of the GID system terminal. According to the intelligent traffic solution scheme based on the GID, the mode of 'end-tube-cloud' (namely 'communicating, sensing, computing terminal +network+ cloud computing center platform') is used for establishing a collaborative intelligent traffic three-layer network system.

Description

technical field [0001] The invention relates to the field of intelligent transportation systems, in particular to a GID-based intelligent transportation solution. Background technique [0002] At present, the intelligent transportation system provides vehicles with ubiquitous access network, real-time road condition information, multimedia services, auxiliary control, etc. Roadside facilities and vehicles are connected through sensor equipment such as on-board sensors, buried coils, and video detection systems to realize the collection of vehicle surrounding information and road condition information. Then the processor and data server process the collected information in a timely manner, and then release real-time road condition information through roadside facilities (WiMAX base stations, 3G base stations, WIFI access points, satellites, etc.), provide access services for vehicles, and guide vehicles to choose optimal driving path. [0003] The core of intelligent transp...
