Highway Signing for Safety

Report No: 70-R54

Published in 1971

About the report:

Signing that effectively warns the motorist of temporary obstructions on or near a roadway is essential to traffic safety. The general objective of this study was to become familiar with and investigate the suitability of various temporary maintenance signing conditions, with particular attention being given to certain sign combinations and messages, types of warning devices, and a new electronic sign panel for alerting and directing traffic. The effectiveness of the various signing conditions tested was based on observed weaving maneuvers and speeds of vehicles throughout the work area, which was located on a 6-lane rural interstate highway. It is felt that the implementation of the recommendations contained in this report will reduce the accident potential in the operations cited for divided, limited access highways.
