Examining the Effects of a Signless Roadway: Holographic Traffic Control Devices and their Potential for Replacing Traditional Post-Mounted Traffic Control Devices
In this research, the behavior of subjects as they drive on a road containing only traffic control devices (TCD) of holographic nature is evaluated. Subjects participating in the experiment were asked to drive three different scenarios in a full-scale driving simulator. The three different scenarios (A, B, and C) had the same rural two-lane highway geometry. The only difference across scenarios was the TCD included. Scenario A included no regulatory or warning signs. Scenario B included traditional post-mounted regulatory and warning signs. Finally, Scenario C did not include physical signs but relied on holographic-style traffic control devices. To understand the driver behavior, the speed profiles of drivers across all three scenarios were evaluated in order to assess if the use of holographic-style traffic control devices has the potential for replacing post-mounted signs. An analysis of the average speeds at critical points across eight curves within the scenarios suggests that virtual TCD signage could encourage driving behaviors that are similar to those observed in a traditionally signed environment. In accordance with the objective of the research presented, it was determined that in-vehicle-displayed TCD have the potential to replace post-mounted signs. However, more testing is required under an expanded number of scenarios that include different types of regulatory and warnings signs as well as guidance signs.
