Driver error is the cause of 90 percent of all police-reported car crashes in the United States. Currently, U.S. research is focused on countering vehicle collisions. Initially, these could be infrastructure-only systems that rely solely on roadside warning devices to signal drivers. Ultimately, the emerging systems could evolve into cooperative systems that
Traffic lane is the number of lanes of traffic that a traffic engineer plans for bridge or road. It is part of carriageway designated by proper marking and is used to control and guide the driver (typically it is 3.6 m (12 ft). Design lane is the lane designation used by the bridge engineer for live load placement, which 3 m (10 ft). It consists of uniformly distributed load
