Celeration (speed change) behaviour of drivers has been posited to be the best predictor of their traffic accident involvement. The origins of this behaviour, however, have not been specified. A model is therefore introduced, where celeration is partly due to the individual disposition of the driver (i.e., driving style), and partly to the environment (road layout, rules and traffic density). Three measurement problems for celeration were studied; the effect of traffic density, of regular versus irregular routes, and weight of the vehicle (loaded/unloaded) on celeration behaviour. Two small samples of truck drivers in Sweden were measured for several months each. There was a strong effect of vehicle load, with behaviour being more cautious with increased weight. Driving on different roads also yielded differences in behaviour, although the design used did not permit conclusions about what caused these. Traffic volume was not found to have any reliable effect on celeration.
驾驶员的加速度（速度变化）行为被认为是其交通事故参与度的最佳预测指标。然而，这种行为的起源尚未明确。因此引入了一个模型，其中加速度部分归因于驾驶员的个人特质（即驾驶风格），部分归因于环境（道路布局、规则和交通密度）。研究了加速度的三个测量问题；交通密度、常规路线与非常规路线以及车辆重量（满载/空载）对加速度行为的影响。对瑞典的两个卡车司机小样本分别进行了数月的测量。车辆负载有很强的影响，随着重量增加行为会更加谨慎。在不同道路上行驶也会产生行为差异，尽管所采用的设计无法得出关于造成这些差异原因的结论。未发现交通流量对加速度有任何可靠影响。
