In this paper, we present a new approach to evaluate the performance of road and tunnel lighting based on luminance measurements. Combined with the abilities of an ILMD used in a moving vehicle, our proposal allows us to focus on other angles of observation of road more suitable for urban driving. Our first results show that changing angle of observation has an influence on average luminance of road surface and on associated uniformities.

Road lighting measurements are performed capturing low luminances and high luminances in the same image. It is known as High Dynamic Range (HDR) imagery and the technique used here is based on four synchronous CMOS cameras, each dedicated to one luminance range. After geometric and photometric calibration, an image processing algorithm constructs the final 20-bit HDR image. Then threshold increment and visual adaption models are computed to evaluate glare dynamically along a route. For each model, we discuss about the different parameters and their validity in moving situation.
