Abstract:
The phase transitions are investigated in
a continuum speed-gradient model with a static bottleneck
under open boundary conditions. The bottleneck
situation has been studied using two different
approaches—explicit and implicit. The phase diagrams
showing different traffic states are presented. The effect
of strength of bottleneck has been analyzed, and it is
found that the strength parameter has no qualitative
effect in the explicit case while has considerable effect
in the implicit case. Furthermore, the results of both the
approaches are compared, and the consistency between
them is discussed.
