Abstract:

The 2009 Manual on Uniform Traffic Control Devices (MUTCD) provides various options for enhancing the conspicuity of traffic signs (Federal Highway Administration 2009). For the purposes of this study, “conspicuity” refers to the quality or state of standing out and attracting attention. MUTCD examples of enhanced conspicuity for signs are shown in figure 1 through figure 6. Improving the conspicuity of signs may have direct and indirect effects on safety, such as increasing compliance with signs, decreasing speeds, reducing crashes, or other possible improvements. Although the MUTCD provides many options for conspicuity treatments, there is little information or research on the effectiveness of conspicuity treatments on driver behavior. There has been some documentation of multiple conspicuity enhancements being made simultaneously; however, there is little information or research on the effectiveness of conspicuity treatments on driver behavior. State departments of transportation (DOTs) may be considering or using other new or trial treatments that may be effective in influencing driver behavior.
