摘要： An improved roadside marker system wherein each individual reflector means is continuously visible by the driver of a vehicle moving along the roads surface at night-time from an angle of 0.degree. to 60.degree. where 0.degree. extends substantially parallelly to a tangent to the road side portion in the region where each respective one of the reflector means 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.

摘要： 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.
