GM Working On Wi-Fi Direct-Equipped Cars To Detect Pedestrians and Cyclists
cylonlover writes "General Motors is working to expand upon its vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication systems that allow information to be shared between vehicles and infrastructure to provide advance warning of potential road hazards, such as stalled vehicles, slippery roads, road works, intersections, stop signs and the like. The automaker is now looking to add pedestrians and cyclists to the mix using Wi-Fi Direct technology so a car can detect them in low visibility conditions before the driver does."
Why not use heat sensors?
Heat sensors are the wrong technology to use for this. Radar works much better because it can detect cold objects as well, penetrates fog/smoke, and can use the doppler effect to detect if an object is moving. Radar is what the Google Driverless Car uses, and is what most other autonomous vehicles use as well. It is also what most automatic cruise control systems use.
Over the last 4 decades we've employed a variety of engineering improvements like air bags, anti lock brakes, better tires and suspensions, backup cameras, crush zones and so forth. This reduced the accident and death rates through around 1990-1995. Since 1990, those rates have remained almost exactly the same, year on year.
Meanwhile, pedestrian and cyclist deaths have gone up because US road safety consists of "make crashes as survivable as we can for the people in the cars, because we've felt they are inevitable." As a result, the death rates for peds and cyclists is 5-10x that of countries where there are vulnerable user laws. Basically: if you hit a pedestrian or cyclist - you have to prove it was their fault, and if you can't, YOU are assumed at fault. Not the other way around, where we assume it was the fault of the pedestrian or cyclist. Such an injury or death is also a criminal matter.
