Nissan testing sensors for driver early warning

Tweet Japan has infrared sensors hanging from street poles relaying information to car navigation equipment so drivers can map out the quickest routes. Nissan is testing the use of those sensors to provide accident danger alerts to drivers

Nissan plans to gather data to see whether the technology would contribute to reducing accidents and change driver behavior. The Tokyo-based automaker said it hopes to offer its vehicle-alert system commercially by 2010.
