...transponders housed in small gray boxes have been affixed to light poles along several kilometers of local streets ... Vehicles could collaborate with transponders to relay data across long distances to give drivers advance notice about conditions ranging from bad weather to dangerous road conditions to accidents.
How an upcoming Motorola test in Michigan will work:
- Transponder beams out GPS location and color of traffic light to nearby cars.
- Red car uses its GPS data and speed to calculate that it might run light, warns driver.
- Red car sends warning that it might run light; roadside unit relays the warning.
- Blue car receives relayed signal, warns driver that another car might run the light.
