• Abstract:
  This project is aimed at determining the effectiveness of variable message signs in controlling traffic on an Interstate highway during periods of hazardous driving conditions such as fog, vehicle accidents, or congestion. ; The effectiveness of the signs is being measured quantitatively by use of accident records, vehicular speeds, and headways. Insufficient data preclude drawing quantitative conclusions; however, based on data available, interviews with the State Police, and visual observation of vehicular operations, it appears that the signs are effective in controlling traffic operation and thereby preventing accidents during periods of reduced visibility due to fog.
