Some suspect that global positioning systems, or GPS, technology could be a factor in causing a spike in the occurrence of automobile accidents involving drivers going the wrong way on roads. Reporters asked Fulton Schools Professor Ram Pendyala, a transportation engineer, to explain what some of the latest research on the problem is showing about the impact of GPS devices on road safety. There is data speculating that the technology could possibly misdirect drivers in situations where there is a very short distance between an exit ramp and an access point to another road. But Pendyala says the evidence points more to driver error rather than GPS. Still, he adds, with mor reliance on GPS systems, every effort must be made to improve the technology so it can be as effective and reliable as possible.
