Nissan developing system to prevent wrong-way driving

The incidence of drivers going the wrong way up expressway ramps in Japan is apparently high enough to merit a specific effort to combat its occurrence. Nissan is working on a system that combines GPS location, a map database and an advanced telematic computer system to warn drivers if they attempt to go the wrong way. Senior citizens are frequently at the wheel in such wrong-way accidents, and with Japan's ever-growing elder population, it's a forward-looking decision to begin the wrong-way prevention system, though it's burdened with the ungainly title of 'IT-Assisted Road Information System'. Other features of the new system being co-developed with West Nippon Expressway (West NEXCO), include systems to warn drivers of unintended speed changes on ramps and downhill stretches to help further reduce accidents and congestion.
