Pedestrian Route Choice by Iterated Equilibrium Search
Tobias Kretz, Karsten Lehmann, Ingmar Hofsäß
In vehicular traffic planning it is a long standing problem how to assign demand such on the available model of a road network that an equilibrium with regard to travel time or gen…
Applications of the Dynamic Distance Potential Field Method
Tobias Kretz
Recently the dynamic distance potential field (DDPF) was introduced as a computationally efficient method to make agents in a simulation of pedestrians move rather on the quickest…
Simulation of Pedestrians Crossing a Street
Cornelia Boenisch, Tobias Kretz
The simulation of vehicular traffic as well as pedestrian dynamics meanwhile both have a decades long history. The success of this conference series, PED and others show that the i…
Computation Speed of the F.A.S.T. Model
Tobias Kretz
The F.A.S.T. model for microscopic simulation of pedestrians was formulated with the idea of parallelizability and small computation times in general in mind, but so far it was nev…
The use of dynamic distance potential fields for pedestrian flow around corners
Tobias Kretz
This contribution investigates situations in pedestrian dynamics, where trying to walk the shortest path leads to largely different results than trying to walk the quickest path. A…
Pedestrian Flow at Bottlenecks - Validation and Calibration of Vissim's Social Force Model of Pedestrian Traffic and its Empirical Foundations
Tobias Kretz, Stefan Hengst, Peter Vortisch
In this contribution first results of experiments on pedestrian flow through bottlenecks are presented and then compared to simulation results obtained with the Social Force Model…
Counterflow Extension for the F.A.S.T.-Model
Tobias Kretz, Maike Kaufman, Michael Schreckenberg
The F.A.S.T. (Floor field and Agent based Simulation Tool) model is a microscopic model of pedestrian dynamics, which is discrete in space and time. It was developed in a number of…
The F.A.S.T.-Model
Tobias Kretz, Michael Schreckenberg
A discrete model of pedestrian motion is presented that is implemented in the Floor field- and Agentbased Simulation Tool (F.A.S.T.) which has already been applicated to a variety…
Moore and more and symmetry
Tobias Kretz, Michael Schreckenberg
In any spatially discrete model of pedestrian motion which uses a regular lattice as basis, there is the question of how the symmetry between the different directions of motion can…
