| Outline of Final Research Achievements |
Inefficient setting of traffic signal cycles is one of the main causes of congestion. GreenWave is a method for controlling traffic signals which allows one-way traffic to pass through a series of intersections without stopping cars at red lights. There are still two problems with GreenWave. It blocks the crossing traffic, and it forms congestion at entry and exit to the roads with GreenWave.
We propose GreenSwirl for controlling traffic signals, in combination with a route guidance method GreenDrive. GreenSwirl controls traffic signals for a smooth flow of traffic by making signals turn green when cars arrive, and thus allowing cars to run without stopping on circular routes throughout the city. GreenDrive is a navigation system for optimizing the overall control of the city's traffic. We conducted simulation with the road network of Manhattan Island in New York, and confirmed advantages by our method over existing methods in average travel time, fuel consumption, etc.
