Abstract :
Microscopic traffic simulation has proven to be a useful tool for the design and assessment of intelligent transport systems due to its ability to capture the full dynamics of the time dependent phenomena. Dynamic traffic assignment is a useful tool when a global level of dynamic analysis is necessary. Unfortunately analytical tools are not yet mature enough to provide the answers for networks of a sensible size. This paper presents a heuristic procedure based on an origin-destination microscopic simulation using time sliced origin-destination matrices to account for time variations in traffic demand. Paths from origins to destinations are updated in a timely manner depending on changes in link travel times according to changes in traffic conditions. The paper also includes some preliminary results
