Integrating macro and micro simulation in transportation planning and traffic management projects

Abstract

Traffic simulations are the basis for solving complex traffic problems. Conceptual level of simulation depends on the project goals. In traffic management problems, the most common approach is microsimulation with the perception unit of a single vehicle and precise drivers behaviour simulation. On the other hand, the simulation of traffic flow characteristics and the changes in vehicle routes demands for macrosimulation approach based on global relations of traffic flow parameters. In projects where transport demand forecasts are needed, macrosimulation models are important input data sources for microsimulation. In this paper we present methodology for joint use of macro and micro simulation on a case study of Stepa Stepanović estate in Belgrade. Strengths and weaknesses of this approach are emphasized in discussion and conclusions.
