IHOP3 – Economically consistent simulation of travel behavior with MATSim

Projekt:

IHOP3 - simulering med MatSim av resbeteende som är ekonomiskt konsistent

Sammanfattning:
The IHOP project series aims at building Sweden’s next generation strategic transportation model system.
IHOP1 investigated the feasibility of deploying a dynamic and disaggregate network simulation package. IHOP2
developed a technical framework for integrating travel demand models and network assignment packages through
the MATSim technology. IHOP3 moves on to ensure an economically consistent analysis of the travel behavior
simulated in such a system.
The concrete challenge addressed by IHOP3 is as follows. Sweden’s national travel demand model Sampers
is static (i.e. it does not model time-of-day) and aggregate (i.e. it models representative person groups but no
individual travelers). The person/network simulation system MATSim is, on the other hand, dynamic (full days
are simulated second-by-second) and disaggregate (individual synthetic travelers interact in a simulated network
environment).
Given these different resolutions of time and travel demand, different utility functions are used in Sampers
and MATSim, which in turn leads to different models of travel experience, leading ultimately to different cost-
benefit analysis results. The objective of IHOP3 is to devise a simulation method that allows for the economically
consistent integration of Sampers and MATSim, resulting in the specification of a common, fully dynamic and
person-centric, utility function in both Sampers and MATSim. The proposed solution, which is already partially
implemented in Sampers/MATSim, is demonstrated in a small simulation setting, with the objective to indicate
its scalability and readiness for implementation in a production version of the IHOP system.
