![]() ![]() This section describes different Aimsun tools which can be used for verification and validation, and provides guidelines or examples relating to the calibration of behavioural models and dynamic traffic assignment algorithms. In Section 5.5 we turn to the subject of calibration and validation of Aimsun models. We cover three different methods for tackling the problem, based on dynamic user equilibrium (DUE) and stochastic route choice models with and without memory. Solving the dynamic traffic assignment problem using Aimsun is the focus of Section 5.4. Section 5.3 outlines the logic of the microscopic and mesoscopic simulation processes along with information about the behavioural models at each level. Section 5.1 provides an overview of the project development process covering model building, verification, calibration and validation, and analysis of outputs. ![]() The introductory section provides background information together with a discussion of the development principles behind Aimsun: integration, modularity, scalability, interoperability, and extensibility. The main topics discussed are the modelling of section dynamics using microscopic and mesoscopic approaches, and algorithms for solving the dynamic traffic assignment problem. Part of the book series (ISOR, volume 145) Abstract This chapter is dedicated to the Aimsun transport simulation software, with particular emphasis on its dynamic simulation capabilities. ![]()
