APPEARANCE OF MOVING LOCAL CLUSTERS OF VEHICLES ON HIGHWAY WITH BOTTLENECKS

As it is well known, a cluster of cars can appear spontaneously on a uniform road. Recently, a theory was devised to explain this phenomenon. This theory is based on Navier-Stokes equations. The effect mentioned is excited when the traffic density passes a critical value, and when an ever-present inner fluctuation randomly grows to a critical value. Here, the disturbance leading to a traffic jam will be a "bottleneck", which shall be any deviation from a uniform road geometry. It can be caused by a car broken down and resting on the hard shoulder that only slightly obstructs the right lane, as well as by a lane closure due to an accident or a construction site, or a local speed limit. The purpose of this work is to investigate the traffic flow development when a bottleneck is present. The authors determine which critical traffic density or flow is needed for the appearance of a traffic jam, how these values are related to the parameters describing the bottleneck, and what is happening after the formation of a traffic jam. The authors also attempt to classify the variety of occurring phenomena.
