Adaptive Mesh Generation for Approximation of Traffic Flow Equations
This paper introduces a mesh generating algorithm for solving the traffic flow equation as a conservation law equation. The idea behind the new method is to use the characteristic curves and moving non-oscillatory finite ...
A macro model with consideration of driver's reaction time and distance
Reaction delay of the drivers is an indispensable factor for modeling vehicle movements. In this pa- per, we present an extended car-following model with consideration of the driver’s reaction time and distance. A new ...
