Dynamic Traffic Light Control System Using Wireless Sensor Network

We have calculated the vehicle priority based on vehicle
weight, length, and carbon emission rate. And also given
higher priority to those vehicles which have higher passenger
capacity. Lengthy vehicles for instance buses are given high
priority because of their higher passenger capacity. They can
accommodate more passengers than small vehicles like cars,
and bikes.
• We’ve generated a formula to prioritize the length considering the vehicle priority and the number of vehicles
up to a certain distance.
• The green signal timing of each lane will be calculated
based on the required time for passing the different types
of vehicles in each lane. Then using the wireless sensor,
control the duration of the traffic light and determine the
phase.
• Our proposed DTLCS also handles emergency vehicles.
When an EV (emergency vehicle) enters a lane, we have
developed a method to pass the EV as soon as possible
by changing the lane priority. The system has the ability
to resume the previous operation in an efficient way
