Adaptive Traffic Congestion Control Approach with Emergency Vehicle Protocol

Traffic Congestion and an overabundance of cars on the streets are common sights in most of the major Indian cities. Smart road dividers can be expensive to install and maintain, especially compared to traditional concrete barriers or other passive safety measures. This cost may be prohibitive for some cities or regions. Smart road dividers use advanced technologies such as sensors, cameras, and communication systems to detect and respond to changing traffic conditions. This technical complexity can pose challenges for maintenance and repair. This initiative serves as an example of a method for managing traffic signals based on the volume of traffic and the presence of pedestrians. Python Language is used to count the quantity of cars using image processing. Data from both of these devices are sent to the Raspberry Pi. Raspberry Pi 3 used in this system because the execution of output is much accurate and faster compared to other microcontroller. The system received a signal from emergency vehicles based on Radio frequency (RF) transmission, and the Raspberry Pi microprocessor was used to change the sequence back to the regular sequence before the emergency mode was triggered by the system. This strategy will reduce collisions that frequently happen at traffic signal intersections where other cars gathered to give an emergency vehicle a special route. The traffic light management system for emergency vehicles in this project effectively analyzed and applied wireless communication, or radio frequency (RF) transmission. The project's prototype operates on a frequency of 434 MHz, switching to emergency mode when a traffic light is passed by an emergency vehicle and back to regular mode when the emergency mode was not activated. The vehicle counts and the detection of the ambulance of the proposed system is monitored in cloud. In the future, this prototype system can be enhanced by implementing in highways by extending the moving length of the divider.
