Description

Abstract: Travel demand, traffic flow, network operations and land-use models are typically modeled in a decoupled way, i.e. each of the components is modeled separately assuming the others are fixed. Moreover, the models are often developed by different groups for different contexts, requirement, etc. In this paper we present a prototype of a software framework which allows the user to develop an integrated simulation of a transportation system in a standardized, extensible manner, as well as an implementation of an agent-based planning and network operations micro simulation model using this approach. The project uses an agent-based modeling approach to developing an integrated transportation system model. This allows the model to overcome some of the limitations of traditional aggregated transportation models, particularly with respect to sensitivity to behavioral aspects of the travelers. POLARIS project, then, is intended to develop such an modeling framework and demonstrate the benefits of this approach through the implementation of an integrated travel demand and network operations agent-based micro simulation model. The model is intended to be used in evaluating network operations improvements and I TS implementations from a planning perspective. This paper provides background on the POLARIS modeling framework and details the development of several modules using the framework which form the basis of the planning and operations simulation model.
