In 2006, bottlenecks were costing truckers $8 billion annually. Today the duration, extent and intensity of congestion are higher than ever before. Trade traffic is expected to increase by 85% between 2003 and 2020. In the same time period domestic freight is expected to increase by 70%. Expenditures for new capacity are at 4% of what is needed. Therefore, adding more capacity is not a viable strategy for addressing congestion. The key lies in better management of the existing network to process the traffic safely and more efficiently. One of the key bottlenecks in the transportation system is the signalized intersection. A better management of traffic at signalized intersections can significantly improve mobility and safety of trucks and all motorists.

This research proposes to develop a next generation intersection control system called Autonomous Control of Urban TrAffic (ACUTA) for operation of isolated intersections. This approach can be extended for control and operation of a corridor and eventually a network of intersections. ACUTA can result in less congestion delay, fewer stops for trucks as well as all vehicles, decrease in fuel wastage, reduction in emissions and safety benefits. The benefits of ACUTA will increase significantly with the expected increase in freight traffic on the traffic network. Lesser delay and increased travel time reliability directly translates into huge economic savings for the freight companies, customers and the society. In addition, ACUTA can provide real-time optimal route guidance to the trucks resulting in fewer stops and lesser delay for freight traffic. This would also reduce the delay caused to the other vehicles and result in significant reduction in emissions and fuel consumption.
