| Outline of Final Research Achievements |
The keyword of eliminating traffic congestion is "slow-in fast-out". In principle, traffic jams can be shortened by slowly approaching the traffic queue and taking action to quickly get out of the queue. In this research, using the stochastic cellular automaton as the fundamental mathematical model and explicitly incorporating the spatial structure (excluded volume effect) inside the traffic queue which has not been considered in the conventional queuing theory. We have revealed the characteristics of the starting-wave (the chain of reaction). Specifically, the propagation speed of the starting-wave can be characterized by a power function of the density, and in the case where the propagation speed is slow, it is found that the queue is smoothly eliminated by moving from an optimal headway distance.
