DEVELOPMENT OF A TRAFFIC SIGNAL CONTROL SYSTEM THAT PREDICTS TRAFFIC DEMAND

Tokushima Prefectural Police Headquarters introduced 'The New Signal Control Model Based on Real-time Information' for practical implementation, which the National Police Agency began nationally-funded demonstration tests in the 2004 fiscal year, in order to alleviate traffic congestion. This is the first experimental introduction of this system in Japan. By creating a traffic control system that uses traffic demand prediction technology, signal control parameters can be made to respond to traffic fluctuation. Thus, this system can realize the automation of dynamic and detailed signal control. As a result of the experimental implementation, traffic congestion at main signal controlled (area-controlled) intersections in Tokushima City was reduced by about 22% and travel time was shortened by 10% on average. The economic effect of this has been calculated to be more than 10 million dollars per year. For the covering abstract see ITRD E134653.
