The presented contribution aims to illustrate the pedestrian research history on our faculty. Initial aim was to improve the microscopic properties of cellular models of pedestrian movement, focusing mainly on (experimentally) observed behavior.
A custom variant of the Floor Field model was implemented with incorporated original elements that brought the model closer to the reality. In order...
Density is one of the fundamental quantities for a description of pedestrian dynamics. In the last decade, there is an increasing need to define density better than "the count of pedestrians divided by the size of the detector". Hence this contribution deals with the very promising approach defining pedestrian density using the assumption that every pedestrian is a source of the density...
Despite their simplicity, cellular models are able to capture important phenomena of collective behaviour. In order to obtain higher level of realism, indistinguishable particles in cellular models are replaced by agents having various properties or following different strategies.
Several approaches how to introduce heterogenity into multi-agent cellular systems have been investigated in last...
Agent-based cellular models can be used to simulate the process of evacuation of people from a room. The actions and interactions of heterogeneous agents create collective motion and capture complex phenomena of pedestrian dynamics. This thesis presents a multi-agent cellular model based on floor-field model and is extended by a new strategy for solving conflicts when two or more agents...
This paper deals with a thermodynamical traffic gas model, variance of clearances in traffic data and super random states in traffic theory.
The first part offers an introduction to vehicular headway modelling and its history. Furthermore, it is focused on the aforementioned thermodynamical traffic gas model and its mathematical properties. Relevant functions for clearance distributions are...
The Generalized Inverse Gaussian distribution (GIG) is frequently used in the traffic modeling fields. Its properties for non-negative value of parameter $\alpha$ were presented in previous research [1]. The objective of this paper is to follow up discovered relations and further explore properties of GIG with the negative value of parameter $\alpha$, such as normalization constant and the...
This work challenges one section of the gap acceptance theory related to the analysis of unsignalized intersections. The focus is on the methodology for capacity calculations put forward by Siegloch in 1973 which is still widely used today. Analyzing data from a given intersection in Dresden, it is shown that one of Siegloch’s assumptions– exponential distribution of time clearances on the...
Julia is a relatively new programming language whose popularity among people is growing significantly every year. One of the reasons for that is Julia's type system and multiple-dispatch. These two concepts allow building very complex frameworks for solving different tasks (differential equations, neural networks, ... ) that are easily customizable for non-standard problems. An example is the...
