Clearview Font in Traffic Signs: Assessing IDOT Experiences and Needs

The Clearview font has many advantages over previous font practices, such as night legibility and lack of smearing effect. Some of the potential concerns include incompatibility with commonly used background sheeting and sight distance. However, experience in other states to date, as well as experimental studies in the lietarture, suggest that the advantages appear to outweigh the concerns. The main objective of this study is to determine Illinois' progress in using the Clearview font and whether its use has proven successful. While most previous in the literature were mostly done in an experimental in setting, this study (R27-75) aims to determine how the implementation of the Clearview font for signs has affected Illinois and its motorists in a real-world context. Accordingly, the study team is examining the implementation of this font from the perspectives of both installers and motorists. This project will also monitor media reports about the Clearview font and/or this research project. The main field research portion of this study will include both intercept and follow-up surveys with motorists who have encountered Clearview signs. An important aspect of this project will be developing questions that adequately query user perceptions. Some questions will be whether motorists notice a difference between Clearview signs and other signs and how eligible Clearview signs are to them. This will be done for illuminated and non-illuminated locations in order to compare motorist reactions. The final task is the final report, which is accompanied by an interim report in April followed by the final report a year later. There will also be quarterly progress reports along with meetings of the panel every four months.
