| Research Abstract |
This research established a new approach to evaluating instability risk of multiple car-following vehicles based on microscopic shockwave propagation theory. Macroscopic variables such as traffic flow "q" and density "k" are proved to be transformed into the microscopic variables such as inverse of time headway and that of spacing between vehicles. Speed difference weighted by the spacing between vehicles is proved to be the microscopic shockwave speed and used as the instability risk index of three-vehicle car-following. Numerical analysis showed that the proposed risk evaluation model is capable of describing stability, direction and magnitude of the shockwave within one process.
