Design And Achievement Of Telematics Control Evaluation System Based On Real Data

The core of traditional traffic simulation software is the internal driver model, which is a mathematical model used to simulate the road network elements and their mutual relations. Since the road network elements of most simulation softwares are derived from random distribution, Poisson distribution, binomial distribution and so on, flow rates of transportation derived from such method cannot reflect the real transportation conditions, and this will consequently influence its final simulating results.Working as infrastructure of urban transportation, the condition of the traffic control system directly impact on the real traffic. Bad or unsuitable control system in a certain area will seriously reduce the vehicle speed and road capacity, thus causing huge social economic costs and large damages to body and psychological health as well as environment.The essay in the background of Telematics.Current evaluating methods in traffic control systems mainly rely on field trials which has risk factors, costs much, unrepeatable and with limited effects. Therefore, properly evaluating and finding a suitable traffic control system is becoming a urgent.Telematics has become an important field in intelligent transportation research since its emergence, popularity and developing. It provided a possibility to solve current traffic problems. Combined with simulating telematics platform, it uses real traffic datum to evaluate control strategy and control machine, and then gets results from a simulating software that has evaluating function. Such a system is low cost and high reliable, it may provide a practical platform for the relating study and design in the technology and control system of telematics.Introduces telematics and the simulating technology firstly; then describes concerning content in real datum-based telematics simulating evaluation system and its current situation at home and abroad; and then designs the framework of the system and has achieved some of its goals; lastly in the experiment part, it illustrates the operating effect.
