Lane-Based Traffic State Estimation on Freeways Using Empirical Automated Vehicle Data
Athanasia Karalakou, Felix Rempe, Lisa Kessler, Yunfei Zhang, Klaus Bogenberger TRB, 2024 (presented) Full paper We use the data collected from automated vehicles to estimate the macroscopic traffic conditions in freeway. |

Effects of Dynamic and Stochastic Travel Times on the Operation of Mobility-on-Demand Services
Fynn Wolf, Roman Engelhardt, Yunfei Zhang, Florian Dandl, Klaus Bogenberger IEEE ITSC, 2023 Full paper / bibtex We couple the FleetPy and Aimsun to evaluate the effects of dynamic and stochastic travel time on the operation (routing) of Mobility-On-Demand services. |
|
Data-driven Spatio-Temporal Scaling of Travel Times for AMoD Simulations
Arslan Ali Syed, Yunfei Zhang, Klaus Bogenberger IEEE ITSC, 2023 Full paper / bibtex We introduce a spatio-temporal optimization strategy for scaling the link-level network travel times using the simulated trip data without additional data sources on the network state. |
