Time Headway and Platooning Characteristics of Vehicles on Interstate Highways
Mean time headway for platooning vehicles decreased as traffic volume increased. About 18% to 31% of platooning vehicles had a space gap that corresponds to a reaction time of 0.5 second or less, with more than half of these in large platoon of 5 vehicles or more. About 15% to 85% of platooning …

Modeling drivers' acceleration and lane changing behavior
… speed. A probabilistic model, that is based on a time headway threshold, is used to determine the regime the driver belongs to. Heterogeneity across drivers is captured through the headway threshold and reaction time distributions. The parameters of the car-following and free-flow acceleration …

On Statistical Analysis of Vehicle Time-Headways Using Mixed Distribution Models
For decades, vehicle time-headway distribution models have been studied by many researchers and traffic engineers. A good time-headway model can be beneficial to traffic studies and management in many aspects; e.g. with a better understanding of road traffic patterns and road user behaviour, the …

Development and application of dynamic models for predicting transit arrival times
… resulting in the deterioration of schedule/headway adherence and lengthening of passenger wait times. Providing accurate information on transit vehicle arrival times is critical to reduce the negative impacts on transit users. In this study, models for dynamically predicting transit arrival …

A Two-Dimensional Systems Stability Analysis of Vehicle Platoons
… depends on two independent vari- ables such as time t and position within the string k. However, two-dimensional systems describing a vehicle string generically exhibit a singularity at the stability boundary. The existence of this singularity at the stability boundary prevents application of …
