The performed evaluation consisted of two phases: measurement of the illumination levels of (new) LED system and carrying out the public opinion poll on the subjective visual performance of LED in traffic lights. The results of the measured levels of illumination show that deposition of dirt considerably affects its values. The survey results confirm an overall positive impression on LED performances in traffic lights.


Keywords – LED Traffic Lights, deposition of dirt, public opinion poll.
