Ranking of alternatives for emergency routing on urban road networks

Autor: Ting Lu, Sten Ruppe, Marko Woelki

Routing on urban road networks for emergency cars is an application of Dijkstra’s algorithm with relevance in everyday-life. Since distances in urban transport are rather short it is computationally possible to calculate many paths and compare them

Risk minimal routes for emergency cars

Autor: Marko Woelki, Ronald Nippold, Michael Bonert, Sten Ruppe

Publikováno v: WIT Transactions on The Built Environment.

The computation of an optimal route for given start and destination in a static transportation network is used in many applications of private route planning. In this work we focus on route planning for emergency cars, such as for example police, fir

The parallel TASEP, fixed particle number and weighted Motzkin paths

Autor: Marko Woelki

In this paper the totally asymmetric exclusion process (TASEP) with parallel update on an open lattice of size $L$ is considered in the maximum-current region. A formal expression for the generating function for the weight of configurations with $N$

Density-feedback control in traffic and transport far from equilibrium

Autor: Marko Woelki

A bottleneck situation in one-lane traffic-flow is typically modelled with a constant demand of entering cars. However, in practice this demand may depend on the density of cars in the bottleneck. The present paper studies a simple bimodal realizatio

Queuing model of a traffic bottleneck with bimodal arrival rate

Autor: Marko Woelki

Publikováno v: International Journal of Modern Physics B. 30:1541001

This paper revisits the problem of tuning the density in a traffic bottleneck by reduction of the arrival rate when the queue length exceeds a certain threshold, studied recently for variants of totally asymmetric simple exclusion process (TASEP) and

Decoherence-induced conductivity in the discrete one-dimensional Anderson model: A novel approach to even-order generalized Lyapunov exponents

Autor: Marko Woelki, Dietrich E. Wolf, O. Újsághy, Matías Zilly

Publikováno v: Physical Review B. 85

A recently proposed statistical model for the effects of decoherence on electron transport manifests a decoherence-driven transition from quantum-coherent localized to Ohmic behavior when applied to the one-dimensional Anderson model. Here we derive

International audience; We consider the totally asymmetric simple exclusion process (TASEP) on a finite lattice with open boundaries. We show, using the recursive structure of the Markov matrix that encodes the dynamics, that there exist two transfer

Exact matrix-product states for parallel dynamics: Open boundaries and excess mass on the ring

Autor: Michael Schreckenberg, Marko Woelki

In this paper it is shown that the steady-state weights of the asymmetric simple exclusion process (ASEP) with open boundaries and parallel update can be written as a product of a scalar pair-factorized and a matrix-product state. This type of state

Headway oscillations and phase transitions for diffusing particles with increased velocity

Autor: Marko Woelki, Michael Schreckenberg

An asymmetric exclusion process with $N$ particles on $L$ sites is considered where particles can move one or two sites per infinitesimal time-step. An exact analysis for N=2 and a mean-field theory in comparison with simulations show even/odd oscill

Phase Transitions and Even/Odd Effects in Asymmetric Exclusion Models

Autor: Marko Woelki, Michael Schreckenberg

Publikováno v: Traffic and Granular Flow ’07 ISBN: 9783540770732

An asymmetric exclusion process with periodic boundary conditions is investigated. During each time-step a randomly chosen particle moves one site and if possible two sites. This dynamics leads to different gap distributions depending on the parity o
