An approximative analysis of the Hydrodynamic Theory on traffic flow and formulation of a traffic simulation model.

An approximative analysis is introduced to the Hydrodynamic Theory. For an analysis of traffic phenomena in the time- distance space, waves which have continuous property over the space are approximated by some discrete dislocations (referred to as quasi shock waves), the behaviour of which is similar to that of shock waves. The graphic construction successive computation of the queue tail trajectory and a procedure are presented.
