Derivation of a Fundamental Diagram for Urban Traffic Flow
Despite the importance of urban traffic flows, there are only a few theoretical approaches to determine fundamental relationships between macroscopic traffic variables such as the traffic density, the utilization, the average velocity, and the travel time. In the past, empirical measurements have primarily been described by fit functions. Here, we derive expected fundamental relationships from ...
متن کاملThreshold queueing describes the fundamental diagram of uninterrupted traffic
Greenshields [13] captures the empirical relation between speed, flow and density for uninterrupted traffic in the fundamental diagram, see Figure 1. Mathematical models for uninterrupted traffic have been developed and the fundamental diagram in its basic form is now well-understood, see e.g. Newell [29, 30, 31] for a concise exposition. Traffic jams are a major concern for highway operation a...

15 صفحه اولThe Derivation of the Fundamental Superconducting Interaction and the Phase Diagram of Cuprates
We show that an electronic phase separation (EPS) transition described by the Cahn-Hilliard theory yields regions of low free energy forming grains of low and high charge densities. These local differences in the potential energy are studied numerically and used here for the first time as the origin of an attractive interaction that gives rise to local pair formation. The resistivity transition...
