Title:
Reduced Visibility due to Fog on the Highway: A Synthesis of Highway Practice (Summary and Conclusions only)
Abstract:
This document reproduces the Summary and Conclusions of "NCHRP Synthesis of Highway Practice 228: Reduced Visibility Due to Fog on the Highway." The synthesis describes the forecasting and detection of fog, as well as countermeasures that are used by state and local transportation agencies to dissipate fog and to warn motorists during reduced visibility conditions. The presence of fog has often resulted in serious collisions due to reduced visibility. The publication presents a generalized background on the causes of fog, fog forecasting and detection methods, and how fog affects the roadway and the driver. The various countermeasures practiced by transportation agencies that are described herein range from techniques to dissipate fog to a variety of warning systems to alert drivers to adverse conditions.
