    Collisions within intersections constitute approximately twenty-six percent of all Police-reported crashes each year. Of these crashes, 47 percent occur at intersections controlled by stop signs. About 75% of intersection crashes may be attributed to driver errors, such as failure to observe the traffic control or driver inattention. Calspan is developing an on-board countermeasure system to preve... View full abstract»
