Therefore, the behavior prediction that the driver should perform when the preceding vehicle braking is the key to improve the effectiveness of the warning system. This study was conducted to acquire characteristics in the car-following behavior when confronted by the braking of the preceding vehicle, including the reaction time and operation behavior, and establish a behavior prediction model. A driving experiment on the expressway was conducted using devices, such as millimeter-wave radars and controller area network (CAN) bus data, to acquire 845 segments of car following when the brake lamps of the car ahead are on. Data analysis demonstrates that the mean of time distance of car following, mean of car-following distance, and time-to-collision (TTC) mean are closely related with whether or not the driver slowed the car down. The operation states of the driver were divided into keeping the unchanged state of the degree of accelerator pedal opening, loosening of accelerator pedal without braking, braking, and other special situations with the input variables of car-following distance, speed of driver\u2019s car, relative speed, time distance, and TTC using the support vector machine (SVM) method to build a prediction model for the operation behavior of the driver. The verification result showed that the model predicts driving behavior with an accuracy rate of 80%. It reflects the actual decision-making process of the driver, especially the normal operation of the driver, to loosen the accelerator pedal without braking. This model can help to optimize the algorithm of the rear-end accident warning system and improve intelligent system acceptance.<\/jats:p>","DOI":"10.1186\/s13638-020-1639-2","type":"journal-article","created":{"date-parts":[[2020,1,8]],"date-time":"2020-01-08T16:02:47Z","timestamp":1578499367000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["A driver\u2019s car-following behavior prediction model based on multi-sensors data"],"prefix":"10.1186","volume":"2020","author":[{"given":"Hui","family":"Wang","sequence":"first","affiliation":[]},{"given":"Menglu","family":"Gu","sequence":"additional","affiliation":[]},{"given":"Shengbo","family":"Wu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3531-1215","authenticated-orcid":false,"given":"Chang","family":"Wang","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2020,1,8]]},"reference":[{"key":"1639_CR1","doi-asserted-by":"publisher","first-page":"182","DOI":"10.1016\/j.trc.2016.07.014","volume":"71","author":"Z Zheng","year":"2016","unstructured":"Z.
