Postdoctoral research position in modeling travel behavior using multi-agent systems and activity-...

Job Type: FullTime
Deadline: 31 Aug 2021

Czech Technical University in Prague now offers a new fellowship program, the CTU Global Postdoc Fellowship. This new and attractive two-year fellowship-program offers excellent researchers who have recently completed their PhD the chance to continue their research career at CTU. Fellows receive a two year fellowship and become members of a team led by a mentor.

The topic focuses on modeling of travel behavior using multi-agent systems. This topic belongs to the field of activity-based approach to travel demand analysis. Activity-based modeling treats travel as being derived from the demand for activity participation. The focus is thus not only on modelling traffic, but activity participation of citizens. MATSim - an open-source framework for implementing large-scale agentbased transport simulations – will be used as a primary tool. MATSim is a microsimulation platform implemented as a Java application. It also adopts the activity-based approach to generate and simulate individuals' activities. Agent stands for the individual travelers, and agent behavior refers to an individual's daily activity travel plan and route choice. This topic however includes also data preparation, generation of synthetic population and generating daily plans for each citizen / agent. Additionally, so-called “scoring function”, will be researched. When agents execute their plans, the plans are scored according to their economic utility. In the MATSim software, a co-evolutionary algorithm is used to obtain stochastic user equilibrium. The scoring function is needed for the co-evolutionary optimization to model impact of certain policies and decisions. MATSim has been successfully used in large projects abroad, for example in Switzerland, Germany or the USA. Its application in Czech Republic would help, especially in connection to traditional traffic simulation models, such as PTV VISUM used in the city of Prague.
