() Control of Variable Speeds in Temporary Traffic Control Zones (Work Zones) using Changeable Message Signs with Radar. 74th Armual Meeting Transportation Research Board GEORGE L.E., HOFFSTETTER D.K. & WAGNER D.R. ( Variable) Message Fog Hazard Warning Signs to Control Vehicle Operating C Characteristics.   In order to analyze the effectiveness of the CV-VSL application, a connected vehicle testing platform was established based on a driving simulator, and characteristics of the drivers’ speed adjustments after receiving warnings were analyzed with respect to different levels of visibility (i.e., no fog, slight fog, and heavy fog).Cited by: 5. With bespoke Vehicle Activated Hazard Warning Signs, we can provide the right signage for all road speeds and locations. With our Variable Message Signs (VMS) – a single sign can serve multiple functions – ideal for areas with continuously changing conditions or multiple hazards. Examples include physical barriers between the driver and passenger compartments that protect taxi drivers from an attack by a passenger, divided highways that isolate motorists from the risk of colliding with oncoming vehicles, and vehicle safety features such anti-lock braking systems, back-up cameras and lane departure warning systems.

  One of four sign conditions (variable message sign only, in-vehicle unit only, both variable message signs and in-vehicle unit, and none) was randomly assigned to each subject. For each sign condition, two types of weather conditions (fog and no fog) and two types of incidents (presence of snowplows and no snowplows) were incorporated. The message should be printed in black or red letters on a white background, or white letters on a black background. Additional safety symbols may be included in the message area. Warning signs represent a hazard level between caution and danger. “Warning” indicates a hazardous situation which, if not avoided, could result in death or. Advisory speed--The recommended speed for vehicles operating on a section of highway based on the highway design, operating characteristics and conditions.
