Abstract
Analysis of relation between flow speed and jam condition of automobile traffic flow on an express way is necessary to achieve appropriate traffic flow. As it is very difficult to use large number of measuring points as a road network composes a large-scale system, practical methods of analysis have been carried with the measurement of flow conditions on small number of measuring points on a road. It should be noted, however, that there is an important problem on estimated accuracy due to the nonlinear behavior of traffic flow especially on the tail part of jam condition. This papaer reports a graphical interpolation method to estimate the density field of flow concentration. The traffic flow is expressed as compressive flow, and this model is analyzed by the nonlinear partial differential equation. The results are given by the combination of the characteristic lines method and graphical interpolation method.
