Traffic jams

In this project, traffic simulation according to the cellular automaton of the Nagel-Schreckenberg model (1992) with different boundary conditions. The sudden occurrence of traffic jams is successfully realised as well as boundary induced phases and phase transitions are observed in the Asymmetric Simple Exclusion Process. The extension to the Velocity Dependent Randomization model leads to metastabile high flow states and hysteresis of the flow. The impact of speed limits on the probability of the formation of traffic jams is investigated.

I present the investigation involving two extensions of the cellular automaton based NagelSchreckenberg model, the Velocity-Dependent-Randomisation (VDR) model, and the two-lane model for symmetric and asymmetric lane changing rule sets. The study of the VDR model outlines a potential method in extending the lifetime of a metastable state and consequently postponing an inevitable traffic jam by orders of magnitude. The two lane model produces a so called "critical" and "sub-critical" flow which combined cause the collapse of flow at a critical density.

Telecommuting: will it change the world? Telecommuting will have major effects in the worlds of work and family life. However, its biggest effect will be in the area of individual freedom, responsibility, and time management. Work and workplaces will alter dramatically. Offices may become smaller, as fewer desks are needed. There will be greater need for highbandwidth connections to link the office and the home, and even homes to other homes, as other employees and supervisors also begin working at home.
