A two-dimensional multi-class traffic flow model

Jamming transition in a two-dimensional traffic flow model.

Phase transition and critical phenomenon are investigated in the two-dimensional traffic flow numerically and analytically. The one-dimensional lattice hydrodynamic model of traffic is extended to the two-dimensional traffic flow in which there are two types of cars (northbound and eastbound cars). It is shown that the phase transition among the freely moving phase, the coexisting phase, and th...

Toward a Longitudinal, Multi-Dimensional Class Model

Two Dimensional Mixed Traffic Flow Considering the Transit Traffic

Based on the two-dimension cellular automaton traffic flow model (BML model), a mixed traffic flow model of urban traffic that considering the transit traffic is established in this paper by using theDon't block the box rules. We have investigated the influences of the transit traffic ratio, and found that, in most cases, the urban traffic flow exhibited jam phase. Moreover, focusing on the tra...

Probabilistic Multi-class Scene Flow Segmentation for Traffic Scenes

A multi-class traffic scene segmentation approach based on scene flow data is presented. Opposed to many other approaches using color or texture features, our approach is purely based on dense depth and 3D motion information. Using prior knowledge on tracked objects in the scene and the pixel-wise uncertainties of the scene flow data, each pixel is assigned to either a particular moving object ...

A five-vertex model interpretation of one-dimensional traffic flow

Here we solve a discrete one-dimensional traffic flow problem by mapping the allowed sets of car trajectories onto a line representation of the five-vertex model configurations. The fundamental flow diagram, obtained previously in a grand canonical ensemble, is rederived. Fluctuations of the flow are described quantitatively and two critical exponents are defined. The zero-density limit is stud...
