Are the traffic signals synchronized?

The Town uses both coordinated and free or tuneless modes. 

During the majority of the day, coordination occurs between signals along our major corridors. Coordination is largely a strategic approach to synchronize signals together to provide smooth flow of traffic in order to reduce travel times, stops and delay along a corridor. 

Free or tuneless mode operation is generally utilized at traffic signals that are isolated and are not in close proximity to other traffic signals. This operation is also utilized in the lowest traffic volume periods between 11pm and 6am to reduce overall intersection delay.
