Traac Jams
The ow of vehicular traac has been studied in many diierent ways. After an introduction, we will give overview of several models for the ow on single lane road: a uid dynamics theory, a approach based on the dynamics of individual vehicles and a model using a cellular automata. The latter model will be used to study to ow in two dimensions representing the traac in a city with crossings and tra...
متن کاملDeterministic models for traffic jams
We study several deterministic one-dimensional traffic models. For integer positions and velocities we find the typical high and low density phases separated by a simple transition. If positions and velocities are continuous variables the model shows self-organized criticality driven by the slowest car.
متن کاملTiger moth jams bat sonar.
In response to sonar-guided attacking bats, some tiger moths make ultrasonic clicks of their own. The lepidopteran sounds have previously been shown to alert bats to some moths' toxic chemistry and also to startle bats unaccustomed to sonic prey. The moth sounds could also interfere with, or "jam," bat sonar, but evidence for such jamming has been inconclusive. Using ultrasonic recording and hi...
متن کاملTraffic jams: dynamics and control.
This introductory paper reviews the current state-of-the-art scientific methods used for modelling, analysing and controlling the dynamics of vehicular traffic. Possible mechanisms underlying traffic jam formation and propagation are presented from a dynamical viewpoint. Stable and unstable motions are described that may give the skeleton of traffic dynamics, and the effects of driver behaviour...
