Nissan is about to begin a new phase in its ongoing intelligent transportation system (ITS) project. The idea is that traffic signals can incorporate new technology to help reduce traffic congestion and pedestrian accidents. Using a section of roadway at the company's Kanagawa campus show above, Nissan has fitted new signals and roadside monitors to gather data about traffic flow and pedestrian movements. Some employee cars are actually fitted with data acquisition devices, but they won't need to be as the technology progresses. Rather, the signals themselves will eventually be able to collect all the data in the future.
Of particular interest are things like the length of signal cycles that allow pedestrians to safely cross the street, and the fact that during light traffic times, pedestrians often ignore signals, sometimes with disastrous results. With "smart" traffic lights, the system could offer a walk signal to pedestrians during light traffic for longer periods of time, thus discouraging the practice of jaywalking. There are even implications here for environmental advancements, as signal timing can reduce the idling and stop-and-go situations that add a considerable amount of pollution to the air.
The full release is after the jump.
