Traffic conflict techniques, which analyze the safety situations from the aspect of more observable traffic events than crashes, are the most prominent techniques to date. This study provides a comprehensive review of previous research on traffic conflict techniques, striving to find answers to the following open questions: What is a traffic conflict? How to collect the traffic conflict data? And what is the ground to claim that traffic conflicts can be valid surrogates for crashes? The strengths and weaknesses of available answers to these questions are assessed based on methodological and empirical grounds. Directions for the future research are identified and outlined. It is believed that following recommended future directions may offer convincing answers to identified open questions.<\/jats:p>","DOI":"10.1139\/cjce-2013-0558","type":"journal-article","created":{"date-parts":[[2014,5,28]],"date-time":"2014-05-28T21:34:30Z","timestamp":1401312870000},"page":"633-641","source":"Crossref","is-referenced-by-count":253,"title":["Traffic conflict techniques for road safety analysis: open questions and some insights"],"prefix":"10.1139","volume":"41","author":[{"given":"Lai","family":"Zheng","sequence":"first","affiliation":[{"name":"School of Transportation Science and Engineering, Harbin Institute of Technology, 202 Haihe Road, Nangang District, Harbin, Heilongjiang, China."},{"name":"Department of Civil and Environmental Engineering, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karim","family":"Ismail","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Carleton University, 1125 Colonel By Drive, Ottawa, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianghai","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Transportation Science and Engineering, Harbin Institute of Technology, 202 Haihe Road, Nangang District, Harbin, Heilongjiang, China."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1080\/15389588.2011.621472"},{"key":"refg2\/ref2","unstructured":"Allen, B.L., Shin, B.T., and Cooper, P.J. 1978.
