    Abstract
  • The traffic flow modelling was established by shock wave simulation method. It is showed that a shock wave speed distribution in red light period at a plane intersection satisfies a normal assumption, as well as Poisson assumption. Based on completely jammed model, the wave speed increases as an exponential function of the traffic flow quantity. Traffic behavior parameter value may change 0 02~0 30 across the interrupted surface. The non-completely jammed model can calculate a control traffic quantity at upstream entrance of a bottleneck. 4 tabs, 8 refs.
