| الوصف: | The investigation of weather effects on traffic intensity is important from a road safety point ofview, because traffic intensity is noted as the first and primary determinant of traffic safety. Nextto traffic safety, weather conditions affect other predominant traffic variables, namely trafficdemand and traffic flow. Therefore the main objective of this study is the identification andcomparison of weather effects on traffic intensity at different site locations. To assess the impactof weather conditions on traffic intensity, the upstream and downstream traffic of four trafficcount locations are considered. The traffic intensity data originate from minute data coming fromsingle inductive loop detectors, collected by the Flemish Traffic Control Center. Data concerningweather events were recorded by the Royal Meteorological Institute of Belgium. The mainmodeling philosophy envisaged in this study to identify and quantify weather effects is the linearregression approach. Most appealing result of this study for policy makers, is the heterogeneityof the weather effects between different traffic count locations, and the homogeneity of theweather effects on upstream and downstream traffic at a certain location. The results alsoindicated that snowfall, rainfall and wind speed have a clear diminishing effect on trafficintensity, while maximum temperature significantly increases traffic intensity. Furthergeneralizations of the findings are possible by studying weather effects on local roads and byshifting the scope towards travel behavior. Simultaneously modeling of weather conditions,traffic intensity rates, collision risk and activity travel behavior is certainly a key challenge forfurther research. |
