Abstract

This invention relates to a traffic information process system used in city high-speed roads composed of an outer field system and an internal field system, among which, the outer field includes optical-end devices and a master control computer the internal system is made up of an information process system, optical-end devices are connected with an outer field signal collection device and connected to form a ring net in a ring topological structure, the master control computer is connected with the optical-end devices and connected to the information process unit to finish signal analysis and strategy control.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to the collection, transmission and processing of information, in particular to the collection, transmission and processing of traffic information, in particular to a traffic information processing system for urban expressways. Background technique: [0002] In the prior art, the traffic information processing system is widely used in the intelligent traffic system. Australia's SCAT control system adopts a hierarchical information processing system, which is divided into central processing unit-regional processing unit-signal processing unit. The processing method is not real-time simulation, but feedback according to pre-categorization. The SCOOT system in the UK uses an online computing information processing system. The system processes the information collected at each point in real time and provides an adaptive control scheme. However, these traffic information processing systems in t...
