Title: Advanced Modelling of Traffic Flow Dynamics and the Need for Wide Area Detection
Abstract The ITS program established in the early 90s was mainly motivated by the need for advanced traffic management to address growing traffic congestion in street and highway networks. In spite of advances in technology since then, optimal control of oversaturated intersections, arterials and freeways continues to be a major challenge requiring progress both in basic and applied research. However, effective optimal control requires realistic modeling of traffic flow dynamics. In this regard no major advances can be reported in several decades.To be sure, traffic control software available in practice continues to rely on simplistic one dimensional flow modeling developed in the 50s and 60s. In this presentation this modeling is briefly reviewed along with an advanced continuum alternative pointing to the need for wide area detection for data collection and model validation. Advances in this detection technology along with applications in traffic management are also presented.
