Selective enforcement, the practice of targeting specific traffic offenses which figure prominently in the crash problems experienced by a community, is an integral part of practically every traffic safety program. The purpose of this report was to summarize the findings of several evaluations of selective enforcement projects and to propose a seri

Verglimit is a calcium chloride based material that is incorporated into bituminous surface mixes to prevent ice and snow from sticking to the pavement. Two test sections were installed and the effectiveness of the Verglimit was evaluated for two winters. There were design and construction problems associated with the specified high density of the

In permafrost areas, the analysis of soil thermal and hydraulic regimes is complicated by phase change effects and by moisture migration. During freezing, mobile soil moisture is drawn toward the freezing front, increasing the available latent heat; therefore, it is critical particularly in unsaturated soils, that moisture transport and soil water

The need for improvement at a rail/highway crossing typically is based on the Expected Accident Rate (EAR) in conjunction with other criteria carrying lesser weight. In recent years new models for assessing the need for improvements have been developed, and in the research reported here five such models selected from a list established from a liter
