Integrating human psychology into car-following models for accurate response prediction: a realistic approach
… other hand, kinematic data was taken from the NGSIM dataset. The measured behavior and relevant kinematic data were then utilized in the new car-following model, which outperformed the baseline model in performance indexes. Therefore, our research presents a new mathematical model that …

A Study on Use of Wide-Area Persistent Video Data for Modeling Traffic Characteristics
… microscopic traffic data. Even datasets like the NGSIM data are restricted in either time or space. Trajectory data of all vehicles over a wide area during an extended period of time can provide new insight into microscopic models. Persistent wide-area imagery provides a source for this data. This …

Development of A Trajectory Population Data and its Application in CAV Research
… prediction algorithm is conducted using the NGSIM I80 database. A frame-by-frame learning method is developed to join the identified missing trajectories. This data analytics approach preserves the naturalistic property of the trajectory, which was a concern of previous traffic-flow …

A comparison of driving characteristics and environmental characteristics using factor analysis and k-means clustering algorithm
The dissertation aims to classify drivers based on driving and environmental behaviors. The research determined significant factors using factor analysis, identified different driver types using k-means clustering, and studied how the same drivers map in each classification domain. The research …
