FloeMTITS2011 TRANSP-OR TALK Flötteröd, Gunnar Bierlaire, Michel Metropolis-Hastings sampling of paths 2011 Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS) KU Leuven, Leuven, Belgium June 22, 2011 We consider the previously unsolved problem of sampling paths according to a given distribution from a general network. The problem is difficult because of the combinatorial number of alternatives, which prohibits a complete enumeration of all paths and hence also forbids to compute the normalizing constant of the sampling distribution. The problem is important because the ability to sample from a known distribution introduces mathematical rigor into many applications, including the estimation of choice models with sampling of alternatives that can be formalized as paths in a decision network (most obviously route choice), probabilistic map matching, dynamic traffic assignment, and route guidance.
