Resumen: Urban traffic is interesting not only due to its obvious social and economical impact, but also due to its complexity. It is not unusual for drivers to get stuck in a traffic jam that apparently emerged from nowhere. A situation like this is believed to emerge from a sudden change in the driving of some vehicle combined with the reaction time of neighboring drivers. In this way, a perturbation induced by some driver will back propagate through the system possibly affecting vehicles far away. In this article, we study the acceleration behavior of a given driver as one of the possible causes leading to a traffic jam. We based the present study on a previous work that showed theoretically the intrinsic chaotic nature of the traffic in cities, and we extend those results to a broader range of accelerations and deceleration ratios. In this way, our simulations suggest that high deceleration/acceleration ratios may be at the root of emergent traffic jams.
