Abstract

A comparison was made on a one-fortieth scale model bridge of a conventional cut-off street lighting system mounted at a height of 25 ft and a spacing of 100 ft with a system comprising lanterns sending their main beams transversely across the road and mounted at a height of 12 ft and a spacing of 50 ft. The results indicate that the transverse system of lighting may be at least as effectives as the conventional system in revealing cars when the light flux on the road is the same.
