Also the attitude to countermeasures related to information or driver support system was studied. A random sample of 3041 persons was drawn from the national register of vehicle owners. The response rate was 62%. The most common countermeasures were to stop to take a walk (54%), turn on the radio\/stereo (52%), open a window (47%), drink coffee (45%) and to ask passengers to engage in conversation (35%). Logistic regression analysis showed that counteracting sleepiness with a nap (a presumably efficient method) was practiced by those with experience of sleep\u2010related crashes or of driving during severe sleepiness, as well as by professional drivers, males and drivers aged 46\u201364\u2003years. The most endorsed means of information to the driver about sleepiness was in\u2010car monitoring of driving performance providing drivers with information on bad or unsafe driving. This preference was related to experience of sleepy driving, not being a professional driver and male gender. Four clusters of behaviours were identified: alertness\u2010enhancing <jats:italic>activity<\/jats:italic> while driving (A), <jats:italic>stopping<\/jats:italic> the car (S), taking a <jats:italic>nap<\/jats:italic> (N) and ingesting coffee or other sources of <jats:italic>caffeine<\/jats:italic> (C) (energy drinks, caffeine tablets). The participants were grouped according to their use of any of the four categories of countermeasures. The most common cluster was those who used activity, as well as stopping and drinking caffeine.<\/jats:p>","DOI":"10.1111\/j.1365-2869.2008.00633.x","type":"journal-article","created":{"date-parts":[[2008,2,12]],"date-time":"2008-02-12T06:27:57Z","timestamp":1202797677000},"page":"16-22","source":"Crossref","is-referenced-by-count":64,"title":["Driver sleepiness and individual differences in preferences for countermeasures"],"prefix":"10.1111","volume":"17","author":[{"given":"ANNA","family":"ANUND","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G\u00d6RAN","family":"KECKLUND","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"BJ\u00d6RN","family":"PETERS","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TORBJ\u00d6RN","family":"\u00c5KERSTEDT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2008,2,11]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.3109\/07420529709001149"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2869.2001.00248.x"},{"key":"e_1_2_6_4_1","volume-title":"VTI Meddelande 933","author":"Anund A.","year":"2002"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1037\/11772-000"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/00140137908924702"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1080\/00140139308967981"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/001872089403600210"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0001-4575(97)00032-8"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0001-4575(00)00013-0"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1136\/ip.7.3.194"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-008043357-8\/50012-1"},{"key":"e_1_2_6_13_1","article-title":"Pilot test of fatigue management technologies","author":"Dinges D.","journal-title":"US Transportation Research Record, 2005"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1467-7687.2006.00579.x"},{"key":"e_1_2_6_15_1","first-page":"175","article-title":"Fatigue in industry","volume":"36","author":"Grandjean E.","year":"1979","journal-title":"Br.
