Abstract—The paper discussed the developmentprocedure of headlamp photometric performance and the evaluation mothod of roadscene illumination. It has defined the development procedure of photometricperformance of headlamp.And also, according to safty and comfort of road sceneillumination，we have researched the assessmentof illumination performance in term of road range，pedestrian detection，nearbyillumination，homogeneous，dazzle ,etc.Regulate the technical requirement,performance parameter and test method forroad scene illumination .It has formed the rating system for road sceneillumination of headlamp at last.It ensures that the headlamp meet theindustrical trend and customer’s requirement.

Keywords-component; headlamp，illumination performance，roadscene，pedestrian detection
