On the speed reduction potential of pilot vehicle use in work zones
Debnath, Ashim Kumar, Blackman, Ross, & Haworth, Narelle (2016) On the speed reduction potential of pilot vehicle use in work zones. Road and Transport Research: A Journal of Australian and New Zealand Research and Practice, 25(1), pp. 18-30.
Despite significant research efforts to understand the speed reduction potentials of work zone interventions, little is known about the reductions achievable by the use of pilot vehicles. This paper innovatively examines the speed reduction potential of pilot vehicle in a Queensland rural highway work zone. Analysis of five days’ speed data showed that pilot vehicle reduced mean speeds at the treatment location, but not downstream. The proportion of speeding vehicles was also reduced, particularly those travelling at 10 km/h or more above the posted limit. Motorists were more likely to speed during the day, under a 40 km/h limit and when traffic volumes were higher. While it is commonly believed that pilot vehicle controls the speeds of all following vehicles, results of this study showed that pilot car had greater effects on reducing speeds of vehicles following it closely than those which are far behind in a traffic stream. To maximize these benefits, it is necessary to ensure that the pilot vehicle itself is not speeding.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
