Abstract:
The operational strategies improving traffic conditions on congested freeways include
reducing excessive demand, targeting resources to alleviate accident hot spots, providing
traveler information, and controlling traffic on ramps. Macroscopic traffic models represent
traffic as a compressible fluid in terms of flow, density and speed. Our macroscopic
model of choice is the discretized Lighthill-Whitham-Richards conservation law, known
as Cell Transmission Model (CTM).Aurora Road Network Modeler is a set of tools for
operational planning and management of travel corridors (road networks comprised
of freeways and surrounding arterials) and analysis of their performance. The talk will
focus on the properties and behavior of CTM as nonlinear dynamical system; discuss
how these properties can be used in the state estimation and ramp flow control; and
