SELECTION OF TRAFFIC CONTROLS FOR SEVERE WEATHER CONDITIONS

This manual provides guidelines for the selection of traffic controls to reduce the hazards created by severe weather conditions to travel on limited-access highways. The guidelines emphasize the need to determine the severity of the hazard and to estimate the level of investment that is warranted prior to implementation of a control to counter the hazard. The criteria to be applied to assure that the basic functions of traffic control are achieved are provided as an aid in the selection or design of traffic control measures. Analytical techniques are described in procedural format, along with worksheets, for use by traffic engineers in quantifying the extent of the accident or delay hazard created by extreme weather conditions. A methodology for selection of the most appropriate traffic control is presented based on estimating the level of effectiveness that must be achieved by a control in order to be cost effective. Summary descriptions of traffic controls implemented by the States under various adverse weather conditions, and a comprehensive annotated bibliography are provided in appendices to the report. /Author/
