Traffic signal control system based on remote hosting

Abstract

The invention provides a traffic signal control system based on remote hosting, belonging to the field of intelligent traffic control and management. The system structure comprises a field apparatus part, a remote communication part and a remote hosting center part, wherein the field apparatus part comprises a crossroad traffic signal system and a local traffic data gateway; the remote hosting center part comprises a hosting center signal control system and a hosting center traffic data gateway; the remote communication part is based on the internet and the remote communication connection is realized by the local traffic data gateway and the hosting center traffic data gateway through the internet. The invention realizes the management and the sharing of remote traffic signal control resources by means of the internet based on the virtual machine technology, and realizes the fusion and the sharing of multiple intelligent traffic system data by being compatible with communication protocols of multiple intelligent traffic control systems, thereby realizing the remote real-time coordination control on multi-city and multi-region traffic signals by means of the center traffic control system.

Description

technical field [0001] The invention relates to a traffic signal control system based on remote trusteeship, which belongs to the field of intelligent traffic control and management. Background technique [0002] With the continuous deepening of my country's reform and opening up, the urbanization process is accelerating, and the urban traffic demand is increasing rapidly. The contradiction between the limited traffic resources and the rapidly growing traffic demand has led to a series of problems. Road traffic congestion and its derivative environmental pollution, energy consumption, and frequent traffic accidents have become key issues affecting the normal operation and sustainable development of cities. [0003] As an effective means to solve the problem of urban traffic congestion, the intelligent traffic signal control system has played an important role in regulating the traffic order at intersections, ensuring the safety of intersections, and improving the traffic cap...

AI Technical Summary

Problems solved by technology

Taking the SCOOT system as an example, its software cost is about 1 million yuan, plus the hardware system and supporting central computer room, power distribution, communication and post-maintenance costs, its construction and operation costs are several million yuan, which is very expensive for small and medium-sized cities. It is not a small investment, and a set of SCOOT system can theoretically control thousands of intersections, and its capacity is far greater than the traffic control needs of small and medium cities, which will inevitably cause unnecessary waste

On the other hand, due to the complex technology of the traffic signal control system, the development and debugging of application functions are highly professional, and the system maintenance is difficult. It requires specialized traffic engineering and control professional technicians as technical support to tap the potential performance of the signal control system. There is a serious shortage of talents in this field in our country

Because of this, although some small and medium-sized cities have established traffic signal control systems, they cannot give full play to their effects, and the application effect is not good. The road traffic signal control system can only work in a single-point state. When there are emergencies such as large-scale security tasks and large-scale activities, it is impossible to realize centralized control of signal lights in the command center.
