Working Program Design of a microprocessor system to control traffic lights.

TRAFFIC LIGHT CONTROL SYSTEM USING MICROPROCESSOR

It is also commonplace to alter the control strategy of a traffic light based on the time of day and day of the week. The controller uses input from detectors. Design a microprocessor system to control traffic lights. Detectors can be grouped into three classes: They are however disadvantageous when the signal timing of an intersection would profit from being adapted to the dominant flows changing over the time of the day.

Actual pin connections are listed in Table 1 below. The pins are used to control relay on-off action with the help of relay driver circuits.

Traffic Light Controller Using Microprocessor Aim The main aim of this project is to design a Traffic light controller using microprocessor, interfacing with peripheral device , and program implementing the process.

Many older traffic light installations still use these, and timer-based signals are effective in one way grids where it and detection for non-motorized road users. They are however disadvantageous when the signal timing of an intersection would profit from being adapted to the dominant flows changing over the time of the day. Dynamic Control Dynamic, or actuated, signals are programmed to adjust their timing and phasing to meet changing traffic conditions.

The system adjusts signal phasing and timing to minimize the delay of people going through the intersection. It is also commonplace to alter the control strategy of a traffic light based on the time of day and day of the week, or for other special circumstances such as a major event causing unusual demand at an intersection.

The controller uses input from detectors, which are sensors that inform the controller processor whether vehicles or other road users are present, to adjust signal timing and phasing within the limits set by the controllers programming. It can give more time to an intersection approach that is experiencing heavy traffic, or shorten or even skip a phase that has little or no traffic waiting for a green light.

Detectors can be grouped into three classes: in-pavement detectors, non-intrusive detectors, and detection for non-motorized road users.
