In an effort to improve visual conditions and hence visual performance, lighting engineers have erected fixed lighting installations to (I) raise the general adaptation level of the driver and hence his sensitivity to vision, (II) provide light to reveal objects on the roadway or its surrounds, and (III) delineate the roadway by virtue of the line of luminaires. The effectiveness of this effort, for a certain standard of lighting, is evidenced by the decrease in the number and severity of collisions at night and its viability on a cost/benefit analysis. /Author/TRRL/
