Urban high-speed road traffic state judging and issuing system and method thereof

Abstract

The invention relates to an urban high-speed road traffic state judging and issuing system for the urban road traffic management, comprising a real-time information collecting and processing system and an urban high-speed road real-time traffic state judging system. The real-time information collecting and processing system includes an outfield system and an internal field system. The outfield system includes a traffic parameter coil detector, an optical transmitter and receiver, a master control computer and a traffic information message board. The internal field system includes a traffic parameter database, a GIS database, a traffic state processing and issuing server and a plurality of system operating and monitoring terminals; the traffic state processing and issuing server is connected with the traffic parameter server to obtain the traffic data; the data quantity pretreatment, the mainline route vehicle speed calculation and the operation of the traffic state judging process are performed; finally the traffic state is transmitted to the system operating and monitoring terminal connected thereto and is transmitted to the master control computer of outfield system after determination so as to finish issuing the real-time traffic information on the traffic state message board.

Description

technical field [0001] The invention relates to an urban expressway traffic state discrimination and release system and method thereof, in particular to an estimation method of the travel speed of an urban expressway, and belongs to the field of intelligent transportation research. Background technique [0002] Urban road congestion is an important problem affecting the economic development of our country. With the deepening of the urbanization process and the continuous improvement of people's living standards, the urban population and motor vehicles have increased dramatically, and the urban traffic congestion has become increasingly serious. There are currently two main categories of measures to control traffic congestion: the first category is to expand roads to solve the contradiction that road capacity cannot meet traffic demand in terms of quantity; the second category is to coordinate the above-mentioned contradictions through advanced scientific and technological me...

AI Technical Summary

Problems solved by technology

[0008] The traffic state discrimination methods described in the above patent applications are all applied to the traffic state discrimination of intermittent traffic flow on urban ground roads. Intermittent traffic flow is greatly affected by the timing of intersection signals, and the traffic flow state often fluctuates greatly. The state discrimination method is quite different from the indicators and methods used in expressway traffic flow state discrimination.
