Book excerpt: During the last several decades, the number of drivers and the number of senior citizens driving on U.S highways has increased significantly along with the number of traffic signs. The median age of the drivers has also increased due to the aging population. Traffic signs provide a plethora of necessary information - directions, guidance, warnings, regulations, and recreation. With today's congestion and higher speed, it's very important to recognize the need for brighter and easier to read signs to increase safety among drivers. In the recent years, there has been innovation in the field of traffic engineering, giving rise to numerous innovations in retro-reflective sheeting materials and fonts. It is important to identify the combination of font and retro-reflective sheeting material, which performs best by increasing the legibility distance between the driver and the sign during both day and night time conditions. The objective of the research was to determine the combination of font (among Clearview 5-W, Series E-Modified and Clearview 5-W-R) and retro-reflective sheeting materials (DG3, Type 4 and Type 1) that produces maximum legibility distance. The objective was also to study the safety benefits of the Clearview font. Both field and computer based tests were carried out to find out which combination of font and retro-reflective material produced maximum legibility distance. From field tests it was found that the Clearview 5-W-R font along with Type 1 reflective material produced the maximum legibility distance in day time conditions, whereas Clearview 5-W-R along with Type 4 reflective material produced the maximum legibility distance at night conditions. It was also seen that while the Type 1 sheeting material performed well during day time, it failed to produce good results during night time. In fact it ended up as the worst performing sheeting material during night time. Based on these observations, it is recommended to use the Clearview 5-W-R in combination with Type 4 retro-reflective sheeting as it showed the most consistent performance compared to all other combinations of fonts and DG3 or Type 1 retro-reflective material.

Book excerpt: Researchers at Texas A & M Transportation Institute completed a study of E-Modified, Enhanced E-Modified, and Clearview 5W for overhead and shoulder-mounted guide signs. The overhead guide signs consisted of three 6-letter, 16-inch tall font words stacked over each other at a standard spacing. The test word was on the middle line and had a leading uppercase letter followed by a combination of lowercase ascender and neutral letters, lowercase descender and neutral letters, or all lowercase neutral letters. The word on the top line was "Paying," and the word on the lower line was "Likely." These words were chosen such that the descender and ascender letters encroached on the test words to evaluate the impact of interline spacing. The shoulder-mounted signs consisted of two-digit numbers. Both the word and number legends were chosen to have similar footprints to minimize the likelihood of guessing based on recognition rather than legibility. Legibility distance data were recorded for each word read; however, the researchers completed the analysis based on the legibility index (LI), which is the legibility distance divided by the legend height. A detailed table of previous research is provided in LI values for cross comparison. Similar to previous research, there were mean LI values in some instances for Enhanced E-Modified and Clearview 5W that were larger than E-Modified; however, none of them were statistically significant. The only statistically significant differences reported were with respect to subject age (e.g., 18-35, and 65+) and day versus night, and at night within Clearview 5W with respect to legend type. The mean LI were 68.9 and 45.2 for 18-35 versus 65+ participants in the daytime condition, respectively, and 50.2 and 36.4 for 18-35 versus 65+ participants in the nighttime condition, respectively. It was shown that the cost to implement Clearview 5W would be more expensive than E-Modified, so it was recommended that future research focus on evaluating Clearview 5WR.

The signs were always on the farsides of the intersection but could be either on the right or left side. Intersections of three levels of compplexity were used. A repeated measures design was used. The implications for driving safety were discussed in the context of visual information processing workload, divided attention and multitasking.

This report describes the concept of driver expectancy in the context of the driving task, and provides examples of expectancy and expectancy violations. It includes a procedure for identifying general and specific expectancy violations to enable engineers to develop remedial treatments to deal with expectancy problems.
