Title:

Association of Highway Traffic Volumes with Cold, Snow and Their Interactions

Abstract:

The main objective of this study was to investigate highway traffic volume variations due to severity of cold, amount of snowfall and various combinations of cold and snowfall intensities. Detailed consideration is given to factors such as highway type and location. The study is based on hourly traffic data from 350 permanent traffic counter sites and weather data from 598 weather stations in Alberta, Canada from 1995 to 2005. Results indicate that the impact of cold and snow on traffic volume varies with day of week, hour of day, type of highway and adversity of cold.
