Road lighting design is a complicated system engineering with many quality indexes.A set of road lighting design scheme evaluation method based on analytic hierarchy process（AHP）is established.Through analyzing the evolution indexes of the road lighting system

the weights of evolution indexes is set up.By using each normalized evolution index values

the comprehensive evaluation value of the road lighting design scheme can be calculated and used for decision making.Through analytical comparison of the road lighting design scheme with LED light and high pressure sodium lamps as light sources for example

the conclusion is drawn that the 150W LED lighting system has better illumination quality than the 250W high pressure sodium lamp under the same road condition and lights arrangement.The LED lighting system has obvious energy saving advantage.
