29: Coupling of Concurrent Macroscopic and Microscopic Traffic Flow Models using Hybrid Stochastic and Deterministic Disaggregation

Macroscopic traffic flow models are well suited for the simulation of aggregated effects of collective constraints such as the number of lanes and ramps in highway and freeway networks with a low demand for computer power. However, macroscopic traffic flow models do not readily lend themselves for certain applications. Macroscopic traffic simulators have a poor algorithmic performance in urban networks and they cannot be used to validate effects of upcoming individual control measures such as automated cruise control and merging assistance systems. Obviously microscopic traffic flow models are better suited for such purposes. Past and upcoming research efforts both for integrating motorway and urban control and for integrating individual and collective control measures thus lead to a demand for the coupling of concurrent macroscopic and microscopic traffic flow models.
