Abstract

This invention relates to one city traffic journey time intelligent analysis system, which comprises each road catch identification device in the city traffic internet and intelligent servo with each catch device connected with intelligent servo, wherein, the servo comprises city traffic network topological structure module, car catch identification module, road section even drive time computation module, break judgment module to establish road topological structure and OD matrix relationship; due to number information from catch device, it uses road list to store router topological structure.

Description

(1) Technical field [0001] The invention relates to the field of urban traffic intelligent systems, in particular to an urban traffic travel time analysis system. (2) Background technology [0002] The intelligent transportation system uses advanced information technology and network technology to make full use of the original roads, increase the transportation capacity of the traffic, shorten the transportation time, and save energy. On the other hand, intelligent transportation relies on various advanced control methods and methods to improve driving safety and reliability, greatly reduce the incidence of accidents, reduce casualties and vehicle losses, and also bring social and economic benefits. [0003] On such a complex road network as urban roads, the domestically proposed dynamic path travel time prediction based on the least squares method and fuzzy comprehensive evaluation is only suitable for simple paths and has certain restrictions on traffic conditions, and it ...
