A Variational Formulation of Kinematic Waves: Bottleneck Properties and Examples

This paper has introduced recipes used to solve complex Kinematic Wave (KW) problems with precision and simplicity. The techniques are especially useful for inhomogeneous KW problems with multiple moving bottlenecks. They can be used even if the bottlenecks change the character of the road as they move through it. The new methods are now being applied to complex real-life problems with combinations of gradual, moving, and time-dependent bottlenecks. They can help improve hybrid (discrete/continuous) models of traffic flow, where trucks and other slow vehicles are modeled as underpowered discrete particles that can both generate queues and be slowed by them. The hybrid models that include lane changing are currently being implemented and the initial tests with real data re very encouraging. These models, for example, appear to explain the strange observations of moving bottlenecks, and the detailed merge bottleneck phenomena. The new methods can also be used to simulate intermittent bus lanes and HOV lanes.
