In urban scenarios traffic signal controls are the main
mechanism to control vehicular flow at the intersections.
However, traditional systems fail to adjust the timing pattern in
accordance to the time variability. An alternative to such systems
is to develop dynamic systems which will alter the timing patterns
according to the traffic demand. In this paper, an adaptive traffic
signal control system based on car-to-car communication is
designed and developed. This system reduces the waiting time of
the vehicles at the intersection along with the reduction in queue
length. It’s also verified that the proposed solution is collision free
at the intersections. The proposed system is compared with a
classical pre-timed system. The simulations also show that the
data convergence time and the communication delay between
vehicle and traffic signal do not compromise the efficiency of the
system.
