Measurement systems used in measuring the illuminance of the road

Street lighting is one of the elements of road infrastructure that affects safety. Therefore, the important issue is the verification of the street lighting condition in the context of fulfilling the normative requirements. The currently used method of measuring road illumination with the use of handheld meter is labour-intense and time-consuming, as a result of which the street lighting audit is neglected. An alternative method of measurement is the measurement systems located on the vehicle. The publication presents the methods used in the measuring of the illuminance of road. Attention is paid to the disadvantages of the commonly used static method and an alternative is presented by using mobile systems to measure the lighting condition on the road. Authors presented a change in the concept of measuring systems built over the years, including own concept implemented with the results of pilot studies.
