A REEXAMINATION OF THE ANALYSIS OF FREEWAY BOTTLENECKS

Deterministic queuing analysis and linear shock-wave analysis are methods commonly applied to solve traffic bottleneck problems. In deterministic analysis, traffic passing through the bottleneck is treated as a standard queuing problem. In linear shock-wave analysis, traffic is analogous to a fluid flow in which wave representation of the traffic stream models changes in traffic speeds and densities through the bottleneck. This article reviews these two methods of analysis and attempts to explain the large discrepancies between the results produced. In a numerical example the author reveals that there is very little difference in the results of the two methods when the bottleneck problem is set up compatibly.
