QuerPlaner Buck Heilig GbR was founded in 2017 by combining the freelance activities of Sebastian Buck and Michael Heilig. Both work full-time at the Institute of Transport Studies at the Karlsruhe Institute of Technology (KIT) with Prof. Dr.-Ing. Peter Vortisch, focusing on microscopic modeling and simulation of traffic demand and traffic flow. We advise customers from the public sector as well as private customers from the automotive industry. The focus is on data-driven modeling. The aim is to offer customers the entire process from data acquisition to the processed simulation results.
