摘要

Current IES standards refer to pedestrian lighting in terms ofnminimum vertical illuminance 1.5 m above pavement level. Analysis isnmade to find the vertical illuminance 1.5m above pavement level facingnoncoming traffic for typical street lighting configurations. Three types ofncalculation grids were used to simulate pedestrians on the side walk,non the street and on the median. Streets with and without median arenstudied with various streetlighting layouts such as staggered, andnalong both sides of the street. It was found that in most cases thenvertical illuminance on a two way street peaks on one side of the streetnwhile, it is minimal on the other side of the street at the same lateralnaxis. Plan diagrams of streets showing the locations of verticalnilluminance greater than 1 foot-candle and less than 0.2 foot-candle arenpresented.
