A mobile laboratory has been developed as part of an investigation into the relationship between road lighting and accidents. This paper describes the data collection facilities on the vehicle and associated analysis and processing equipment at the base laboratory for the measurement of all the CIE recommended road lighting quality parameters together with illuminance and individual lantern output. All the data acquisition is carried out while the vehicle is travelling through the installation under investigation and if necessary the variation in lighting performance can be examined in great detail.
