Abstract:
An improved roadside reflector assembly which when mounted alongside a road is continuously visible by retroreflected light by the driver of a vehicle moving along the road at night-time within a viewing angle of from about 0. degree. to 60. degree. relative thereto, where 0. degree. extends substantially parallelly to a tangent to the road in the region where such reflector assembly is located. Also, such driver continuously sees retroreflected light at any given instant of time while approaching and passing a group of the reflector means so employed and so located, the individual such reflector means being longitudinally spaced from one another along such a road.
