对优化速度模型（OVM）、广义力模型（GFM）、全速差模型（FVDM）3种相关跟驰模型的复杂性与适应性进行了研究。采用美国Ⅰ-80高速公路附近30层高楼上所拍摄数字图像，并提取车辆轨迹数据，通过3种不同的标定方式对跟驰模型进行了参数标定，进而从总体、驾驶员间异质性、驾驶员自身异质性3个方面对模型复杂性与应用性进行了对比分析。研究结果表明，OVM，GFM，FVDM 三种模型的应用性和复杂度并不具有一致性，复杂度高的模型在模拟跟驰的应用性上并不一定优于简单模型。研究结果为跟驰行为的建模研究提供了有效信息。

The complexity and applicability of three relative car-following models are investigated and they are the optimal velocity model (OVM),the generalized force model (GFM) and the full velocity difference model (FVDM).The vehicle trajectory data used is collected from the digital pictures obtained at a 30-storey building near Ⅰ-80 freeway.Three different calibrating methods are used to estimate the model parameters and to study the relationships between model complexity and applicability from overall,inter-driver and intra-driver analysis.Results of the three methods of the OVM,GFM and FVDM show that the complexity and applicability are not consistent and the complicated models are not always superior to the simple ones in modeling car-following.The findings of this study can provide useful information for car-following behavior modeling.
