Workers performing mobile highway construction and maintenance operations have traffic moving only a few feet from their work area. Maintenance zone fatalities represent about 10% of all work zone fatalities. Maintenance operations typically consist of mobile operations over a short period. Examples include sweeping, surface patching, and line painting. This study evaluates benefits and limitations of using a truck-mounted radar speed sign (RSS) during mobile maintenance operations by examining four case studies.
This study examined truck-mounted radar speed sign (RSS) displays to help decrease vehicle speed and variability through continuously moving and intermittent mobile work operations.
