• Abstract:
  In California, field maintenance personnel use turntable signs to advise motorists of chain control conditions on rural ; highways and freeways. To do this an operator has to park, exit the vehicle, turn the sign on the shoulder and then ; walk across the freeway to turn the matching sign on the median. This is repeated multiple times for chain control as ; well as for signs indicating icy or snowy conditions. Walking across highways this frequently and in these ; conditions can be hazardous to maintenance personnel. ; Caltrans staff requested a Preliminary Investigation to identify safer and more efficient state practices and tools ; being used to alert travelers to winter weather conditions. We reviewed recent research, national guidance and ; related efforts of other state DOTs to determine: ; • Tools for notifying travelers of chain control requirements and weather conditions. ; • Usage and operation of changeable, dynamic and variable message signs for winter weather notifications. ; • Operation of non-electronic signs.
