Previous studies have observed positive effects of in-vehicle crash warning systems in passenger car drivers. Although heavy-truck drivers are generally more experienced, driver-related errors are still the leading factors contributing to heavy-truck-related rear-end crashes. <\/jats:p><\/jats:sec><jats:sec><jats:title>Method:<\/jats:title><jats:p> Data from a 10-month naturalistic driving study were used. Participants were 18 professional heavy-truck drivers who received warnings during the last 8 months of the study (treatment period) but not during the first 2 months (baseline period). Time headway and driver\u2019s brake reaction time were extracted and compared with condition variables, including one between-subjects variable (driver shift) and five within-subjects variables (treatment condition, roadway types, traffic density, wiper state, and trailer configuration). <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> The presence of warnings resulted in a 0.28-s increase of mean time headway with dense on-road traffic and a 0.20-s increase with wipers on. Drivers also responded to the forward conflicts significantly faster (by 0.26 s, a 15% enhancement) in the treatment condition compared with responses in the baseline condition. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> Positive effects on heavy-truck drivers\u2019 following performance were observed with the warning system. <\/jats:p><\/jats:sec><jats:sec><jats:title>Application:<\/jats:title><jats:p> The installation of such in-vehicle crash warning systems can help heavy-truck drivers keep longer headway distances in challenging situations and respond quicker to potential traffic conflicts, therefore possibly increasing heavy-truck longitudinal driving safety. <\/jats:p><\/jats:sec>","DOI":"10.1177\/0018720812439412","type":"journal-article","created":{"date-parts":[[2012,3,23]],"date-time":"2012-03-23T03:24:14Z","timestamp":1332473054000},"page":"687-697","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":46,"title":["Heavy-Truck Drivers\u2019 Following Behavior With Intervention of an Integrated, In-Vehicle Crash Warning System"],"prefix":"10.1177","volume":"54","author":[{"given":"Shan","family":"Bao","sequence":"first","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor"}]},{"given":"David J.","family":"LeBlanc","sequence":"additional","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor"}]},{"given":"James R.","family":"Sayer","sequence":"additional","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor"}]},{"given":"Carol","family":"Flannagan","sequence":"additional","affiliation":[{"name":"University of Michigan Transportation Research Institute, Ann Arbor"}]}],"member":"179","published-online":{"date-parts":[[2012,3,21]]},"reference":[{"key":"bibr1-0018720812439412","doi-asserted-by":"publisher","DOI":"10.1016\/S0001-4575(03)00040-X"},{"key":"bibr2-0018720812439412","doi-asserted-by":"publisher","DOI":"10.1518\/0018720024497925"},{"key":"bibr3-0018720812439412","volume-title":"Underride in rear-end fatal truck crashes","author":"Blower D.","year":"1999"},{"key":"bibr4-0018720812439412","doi-asserted-by":"publisher","DOI":"10.1016\/0001-4575(93)90025-R"},{"key":"bibr5-0018720812439412","doi-asserted-by":"publisher","DOI":"10.1016\/S0001-4575(99)00014-7"},{"key":"bibr6-0018720812439412","doi-asserted-by":"publisher","DOI":"10.1518\/001872097778543930"},{"key":"bibr7-0018720812439412","volume-title":"Automotive collision avoidance system field operational test: Methodology and results","author":"Ervin R.","year":"2005"},{"key":"bibr8-0018720812439412","unstructured":"Federal Motor Carrier Safety Administration.
