Microcontroller PIC based traffic light system with collision detection

摘要

This paper presents research results of the novel system to control traffic lights which is based on the common European model. One of the most important measures for dealing with this problem is to adopt favorable traffic signal control strategy. The main objective of this research is to develop an effective procedure to control the traffic, which tries to reduce possibility of traffic jams. Additionally, the paper proposes a design and implementation of a microcontroller based system to control traffic lights on an intersection. This traffic light system comprises of PIC32MX440F256H Programmable Integrated Circuit microcontroller, crystal oscillator, power section, and diodes emitting light. For the implementation of the intersection traffic control system, the authors have written within the MPLAB X IDE environment a C language program. The developed system has been tested by constructing a prototype that resembles the real application.
