Congestion is a common traffic phenomenon also widely investigated, both from macroscopic and microscopic perspectives. Yet, current literature lack a unified evaluation of Car-Following models with naturalistic congestion data. This paper compares the performance of five parametric Car-Following models: IDM, ACC, Gipps, OVM, and FVDM, using a rich naturalistic congestion dataset. The five models in question is found to perform similarly when optimized over the same RMSNE metric. Sub-sequences of Car-Following where models noticeably disagree with driver behavior is noticed and separately investigated. A review of corresponding front-facing and cabin video data reveals distraction and driving with momentum as potential reasons for model-reality difference. We further show that drivers often employ coasting and idle creep under Car-Following in different speed ranges, which existing parametric models fail to capture. Finally, time-series clustering is performed and analysis of result clusters align with empirical findings.
Our findings highlight the necessity to consider vehicle dynamical properties including coasting and idle creep abilities, which drivers take extensive use of under low speed congestions. Future research could integrate such parameters with traditional parametric models to improve congestion modeling performance. We also suggest future research into investigating temporal correlations between clustered blocks to reveal behavioral transition patterns exhibited by drivers in congestions.
