(2005) An improved replanning module for agent-based micro simulations of travel behavior. Working paper, 303, Institute for Transport Planning and Systems (IVT), ETH Zurich, Switzerland
An external strategy module for an agent-based micro simulation of trafﬁc systems is presented. It modiﬁes activity durations and departure times of activity plans, which are the agent-based representation of travel demand. The module combines broad search for alternative timing decisions with an optimization procedure of a utility function. The idea is to replace a replanning module that changed timing decisions randomly. Main results are relaxation of the whole simulation system to a better stationary state, and much quicker convergence. The difference in overall performance compared to the previous implementation of the replanning module is one order of magnitude.
