| Abstract | Macro, meso and micro approaches have traditionally grown up independently to provide answers to specific problems in traffic and transportation analysis, however, a proper analysis of complex networks, as in the case of corridor analysis, asks for an integrated combination of the three approaches. Macro travel demand models are usually based on the user equilibrium and are static in nature, while simulation approaches emulate traffic flow dynamics. Mesoscopic approaches are based on simplified flow models with explicit treatment of intersections and allow modeling large networks with high computational efficiency adding the dynamic dimension to strategic planning. Microscopic approaches modeling the individual dynamics of each vehicle by means of car-following, lane changing and other models, consistent with traffic flow theory, incur in higher computational costs but allow a very detailed analysis appropriated for operational planning. A methodology combining macro, meso and micro raises consistency problems on the network representation, the time dependent paths and on achieving dynamic user equilibrium. This paper discusses these problems, proposes a solution based on a combination of computer and traffic modeling and presents computational results to check experimentally the consistency of meso and micro models. |
