Although particle hopping models have been introduced into traffic science in the 1950s, their systematic use has only started recently. Two reasons for this are, that they are advantageous on modern computers, and that recent theoretical developments allow analytical understanding of their properties and therefore more confidence for their use. In principle, particle hopping models fit between microscopic models for driving and fluid-dynamical models for traffic flow. In this sense, they also help closing the conceptual gap between these two. This paper starts out with building connections between particle hopping models and traffic flow theory.
Very simple models of particles hopping on a grid appear too simple to have much similarity to traffic. Yet, some of these models can be proved to gen...
Numerical simulations have shown that the network fundamental diagram (NFD) of a signalized network is significantly affected by the green ratio. An a...
