In recent years, with the rapid growth of my country's urbanization and the number of motor vehicles, the current urban traffic congestion has become a travel "habit", and it has also brought a series of new problems to the traffic management in various places. How to alleviate it? This "habit" requires a new understanding of the current urban traffic.
"Growth" is an inevitable trend. Therefore, in the face of the situation and challenges, the method of using solar studs to control traffic signals reasonably has become the most practical and effective method in the current intelligent transportation environment. On a certain basis, this method tends to use the way of traffic diversion to alleviate the urban road traffic congestion under the new normal, which has become a hot opportunity and challenge.
Modern solar studs traffic signal control is a real-time networked control system for regional solar studs traffic signals that integrates modern computer, communication and control technology, which can realize real-time control of intersection traffic signal solar studs, regional coordinated control, central and local optimization. control.
If referring to the definition and division of the three development stages of urban intelligent transportation, then the traffic signal control can also be roughly defined and divided into three stages: traffic signal control 1.0, traffic signal control 2.0, and traffic signal control 3.0.
Traffic Signal Control 1.0
This stage is the initial stage of the entire solar studs traffic signal control industry. The overall function is simple, the traffic signal control system has been established, and the relevant signal lighting standards have been established, but the system is closed and the function is not strong. Each intersection signal is for individual combat. , information cannot be shared, cannot be networked.
Traffic Signal Control 2.0
At this stage, according to the use of the previous equipment, the accumulation of technology and the continuous update of hardware conditions and technologies, the signal market has entered the era of information exchange, and the system networking information communication has become a necessary condition for the signal, and remote control is popular. , the control platform was born.
Traffic Signal Control 3.0
With the process of urbanization and the increase in the number of motor vehicles, the road conditions have become more and more complex, and the networked signal machines have been unable to undertake the task of traffic sorting. On the basis of , it broke through a series of problems, realized the modern functions such as sensing real-time control, main road coordination and regional coordination, automatic adjustment of timing information according to traffic flow, and completed data interaction with electronic police, traffic guidance and other systems, truly realizing The prosperity of traffic data interoperability.
