Distributed Traffic Signal Control for Maximum Network Throughput (11396S-FM)
For more information on this technology contact:
Traffic signal control is a key element in traffic management that affects the efficiency of urban traffic systems. Most major cities currently employ adaptive traffic signal control systems where the light timing is adjusted based on the current traffic situation.
The invention consists of an algorithm for traffic signal control strategy that requires minimal tuning and scales well with the size of the road network while ensuring satisfactory performance. The algorithm is based in backpressure routing, an approach mainly applied to communication and power networks.
One of the attractive features of this invention is that the algorithm used leads to maximum network throughput without requiring any knowledge about traffic arrival rates. For certain network structures, the algorithm can also be implemented in a distributed manner.
