EFFECTS OF RAIN ON DAILY TRAFFIC VOLUME AND ON DRIVING BEHAVIOUR
EFFECTEN VAN REGEN OP VERKEERSVOLUME EN OP RIJGEDRAG
As part of the project on road and weather conditions, a study was carried out with the aim to investigate the effects of rain on total daily traffic volume, and on driving behavior. With respect to the daily traffic volume, no effect of rain was found. Apparently, rain does not cause a major modality shift towards road traffic. Driving behavior in rain was found to be more cautious than in dry weather. The mean speed and the percentage of short time headways were reduced in rain. Also the percentages of time-to-collisions were reduced in rain. However, since several safety studies reveal a higher accident rate in rain, this adaptation of driving behavior to rain is apparently insufficient to maintain the same level of safety.
