However, existing speed prediction and\n                    <jats:italic toggle=\"yes\">V<\/jats:italic>\n                    <jats:sub>85<\/jats:sub>\n                    models are unable to do so. This paper proposes a speed decision algorithm that is based on the curvature of the preview trajectory. Firstly, the trajectory point in each preview cross-section within the driver\u2019s sight window is determined; the curvature of the preview trajectory is calculated and used as input data. Secondly, an objective function is selected to set the speed control pattern: minimum travel time; maximum comfort; minimum deviation from the reference speed; or multiple weighted objectives. Thirdly, the speed value for the preview cross-section is solved by optimizing the selected objective function. As the sight window rolls ahead, the target speed can be determined along the traveling distance. Because the trajectory generated within the boundary of the pavement is used by the driver, parameters such as the change in curve radius, deflection angle, lane width, and spiral length can change the driving boundary, which can change the trajectory characteristics and thus affect the target speed. Therefore, the proposed algorithm is able to determine the speed for roads with complex shapes. The field validation and simulation cases demonstrated that the target speed profile of different driving patterns can be obtained for different combinations of trajectory and speed patterns. Thus, the model can simulate diverse real-world driving behaviors and explain the diversity in driving speeds of different drivers.\n                  <\/jats:p>","DOI":"10.1177\/0037549717751633","type":"journal-article","created":{"date-parts":[[2018,1,25]],"date-time":"2018-01-25T09:52:07Z","timestamp":1516873927000},"page":"911-930","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Modeling drivers\u2019 speed choice on roads with complex shapes based on the curvature of the preview trajectory"],"prefix":"10.1177","volume":"94","author":[{"given":"Jin","family":"Xu","sequence":"first","affiliation":[{"name":"College of Traffic and Transportation, Chongqing Jiaotong University, China"}]},{"given":"Jun","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Traffic and Logistics, Southwest JiaoTong University, China"}]},{"given":"Yiming","family":"Shao","sequence":"additional","affiliation":[{"name":"College of Traffic and Transportation, Chongqing Jiaotong University, China"}]}],"member":"179","published-online":{"date-parts":[[2018,1,25]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1080\/00423110600563338"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1080\/00423110701432482"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1504\/IJVD.2004.005320"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.trc.2015.07.009"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1080\/00423110701576130"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2015.2420542"},{"key":"e_1_3_3_8_2","first-page":"1354","article-title":"Development of sensitivity term in car-following model considering practical driving behavior of preventing rear end collision","volume":"6","author":"Chung SB","year":"2005","unstructured":"Chung SB, Song KH, Hong SY, et al.
