Abstract
This article is focused on dynamics of the computer simulation module SigmaEva in connection with an unidirectional flow under periodic boundary conditions. The module SigmaEva realizes the discrete-continuous stochastic pedestrian dynamics model that is shortly presented here. A fundamental diagram (speed-density dependance) is an input for the model. Simulated specific flow rates are considered versus input ones for different diagrams. A sensitivity of the model to input diagrams is shown and discussed.

Notes
- 1.
Here and below under “obstacle” we mean only nonmovable obstacles (walls, furniture). People are never called “obstacle”. There is unified coordinate system, and all data are given in this system.
- 2.
We assume that free movement speed is random normal distributed value with some mathematical expectation and dispersion [13].
- 3.
Mainly with value >0,9.
- 4.
All the other initial data were the same for all simulation experiments, including the model parameters. Here we do not discus them and only present values \(k_P=9\), \(k_W=2\), \(k_S=40\).
