Problems solved by technology

After the network in the traditional IT architecture is deployed and launched according to business needs, if the business needs change, it is very cumbersome to re-modify the configuration on the corresponding network devices (routers, switches, firewalls)

Embodiment Construction

[0021] Such as figure 2 As shown, the present invention discloses a software-defined network-based regional traffic signal control system, which includes an S-TSN application layer (S-TSN Application Layer), an S-TSN controller (S-TSN Controller Layer) and an S-TSN In the TSN signal layer (S-TSN Infrastructure Layer), the S-TSN controller is connected to the S-TSN application layer through the S-TSN northbound interface (S-TSN Northbound Interface). In addition, the S-TSN controller is also connected through the S-TSN southbound interface. The interface (S-TSN Southbound Interface) is connected to the S-TSN signal layer.

[0022] Among them, the S-TSN application layer runs on the application server and is used to deploy various regional traffic signal control algorithms. Appropriate traffic signal control parameters (including period, green signal ratio and phase, etc.), so as to achieve the goal of adaptive and coordinated control of the traffic network. In theory, a...

Abstract

The invention relates to a regional traffic signal control system based on software defined networking. The system isolates a signal plane from a control plane, simplifies configuration, management and optimization and consequently realizes centralized management and control of traffic signal control equipment, thus, reliability and safety of the whole signal network are promoted, and compatibility and flexibility of the regional traffic signal control system are improved. By abstraction, a uniform programming interface of the traffic signal network is realized, a regional traffic signal control algorithm can be realized more quickly, and creative application is accelerated; through an OpenSignal protocol, on the one hand, hardware requirement and cost of the traffic signal control equipment itself are reduced, and on the other hand, a closed equipment provider ecology is broken, construction and maintenance cost is reduced, and an orderly competitive market environment is formed.

Description

technical field [0001] The invention relates to an intelligent traffic technology, in particular to a software-defined network-based regional traffic signal control system. Background technique [0002] Traffic congestion is a common problem faced by many major cities in the world. As the main means of alleviating traffic congestion, traffic signal optimization control has experienced the development process of point, line and area. At present, regional traffic signal control has become the main traffic signal optimization control method adopted by cities. With the expansion of city scale and the refined management of traffic, there are more and more traffic signal control devices in urban areas, such as expressway ramp lights, tidal lane lights, variable directional lane lights, etc., composed of traffic signal network (Transportation Signal Networking, TSN) is getting bigger and bigger. [0003] While facing the challenges brought by the increasingly complex traffic sign...
