Research on technology of realizing real-time traffic light control system using PHP

With the development of cities and increasingly busy traffic, traffic lights have become an indispensable part of urban transportation. In view of the common problems of existing traffic light systems, such as vehicle congestion, traffic congestion, etc., this paper proposes a real-time traffic light control system based on PHP, aiming to optimize the management of traffic lights, improve traffic efficiency, reduce traffic congestion and Security issues occur.

First of all, we need to understand how traffic lights work. In traditional traffic light systems, signal timing is controlled based on a preset plan, and signal timing is not adjusted based on actual traffic conditions. This results in the signal lights being too long during peak traffic periods and not being enough during off-peak periods, resulting in traffic jams or a waste of time.

To address this problem, we propose a new real-time traffic light control system. Our system mainly consists of three parts: sensors, signal light controllers and web front-ends. The sensor is responsible for monitoring the data and transmitting it to the signal light controller, which adjusts the signal light time based on real-time data and sends the updated control information to the signal light. The web front-end provides real-time traffic status display, signal light control settings and adjustments.

More specifically, our system needs to be installed on the signal lights at each intersection. We need to use sensors to monitor the number of vehicles on the road, as well as their speed and density. We use ultrasonic sensors or infrared sensors to monitor the number of vehicles and cameras to obtain vehicle speed and density. This data is then transferred to the signal light controller.

The signal light controller uses an algorithm developed based on PHP to analyze the data transmitted by the sensor and adjust the signal light time according to real-time traffic conditions. Because our system adjusts signal timing in real time, traffic conditions can be significantly improved. At the same time, the safety of pedestrians and vehicles also needs to be considered during this process.

The Web front-end is the user interface of the system. Users can set and adjust the signal light controller in the Web interface. The web front-end also provides a display of the traffic status on the page, including the number of vehicles at the intersection, speed and traffic congestion. This can help users better understand the traffic situation and adjust the status of the signal lights in a timely manner.

In summary, our system implements a real-time traffic light control system based on PHP technology. It mainly uses sensors to monitor data and transmit it to the signal light controller. The controller adjusts the signal light time based on real-time data and sends updates. control information to the signal light. Our system displays real-time traffic status through a web interface and provides users with convenient functions to set and adjust signal lights. In the future, we will continue to improve and optimize the system so that it can play a greater role in practical applications and improve the efficiency and safety of urban transportation.
