The use of daytime running lights DRL in The Netherlands : methods of analysis to link data to accidents and a description of the use of DRL in The Netherlands from November 1, 1989 to October 31, 1990.

During the period November 1989 to October 1990, monthly measurements were carried out to study the use of daytime running lights (DRL) by motor-vehicles at 26 different locations in The Netherlands (See also C 55). An important conclusion is that light intensity appears to be the principal variable (for a large group of drivers) explaining variations in the measured use of DRL. Furthermore, recommendations are given on the basis of the analysis of the first twelve months of measurement.
