Microscopic Simulation Model for Mixed Traffic of Connected Automated Vehicles and Conventional Vehicles on Freeways
This study developed mixed-traffic simulation models of connected automated vehicles (CAVs) and manually-driven vehicles (MDVs) at the full-spectrum of mixed penetration rates on a freeway segment by incorporating the car-following and lane-changing models via a conditional linkage to investigate …

Incident-Related Travel Time Estimation Using a Cellular Automata Model
… analysis, queuing theory and cellular automata models, were initially considered, however, the first two macroscopic models were indicated to underestimate travel time by previous literature. A microscopic simulation model based on cellular automata was developed to attain the goal. The model …

Calibration of a FOSIM Model for a Section of the N2 Freeway in Cape Town: Weaving Section at an Off-Ramp
… the vehicle used and road geometry. Traffic models must account for this variation in behaviour to properly analyse this complex reality. Typically, the variation is modelled by distinguishing between different ‘vehicle-driver combinations', whose behaviour is established by the settings of …
