Abstract
A traffic signal control apparatus acquires position information and travel condition information from vehicles around a construction section of a road in wireless communication, and determines a traffic congestion condition at the positions of those vehicles based on the acquired information. The traffic signal control apparatus then controls traffic signals set up on ends of the construction section in a manner that eases the traffic congestion condition around the construction section based on the determination result of the traffic congestion condition.
