Outline of Final Research Achievements

Although various control schemes of traffic signals have been developed, they could not adapt to unpredictable changes in the amount of traffic. To tackle this problem, we here propose an autonomous decentralized control scheme of traffic signals on the basis of physics consideration of the inter-limb coordination of quadrupeds. More specifically, impulses given by red signals or preceding cars are calculated at each traffic signal by using optimal velocity model, and traffic signals are switched so that the impulses are reduced. We performed simulations with changing number of cars, and the results showed that the proposed control scheme works properly under all conditions examined.
