Based on the further research of STCA and F-STCA cellular automata traffic flow model, combined with the actual situation of the symmetric same direction two-lane traffic flow, improved the risk description of vehicle lane-changing in the driving, a more perfect distance constraint rule and cellular automata traffic flow model are proposed, which are more in line with the actual situation of symmetric...
In this paper, a cellular automata (CA) model is extended to simulate the circular movements of Muslim pilgrims performing the Tawaf ritual within the Masjid Al-Haram facility in Makkah. There is scant literature on the implementation of CA in modeling circular motions. Moreover, most of the published studies do not take into account the pedestrian's ability to select the exit route in their models...
Based on the basic symmetric two lane cellular automaton model (STCA), we propose a modified STCA (MSTCA) for mixed traffic flow. In MSTCA, the headway also could be used for lane changing, and then the length for safety criterion would be extended a lot. Lane changing region and first cell for lane changing on the other lane could be located. The situation while there are successive vehicles satisfies...
The railway transportation safety system is a complex dynamic system with spatio-temporal characteristics. However, currently commercial geographical information system (GIS) lacks these capabilities for spatio-temporal analysis and modeling. Cellular automaton (CA) model can provides GIS with a bottom-to-top spatio-temporal modeling frame. The simplicity and flexibility make CA able to simulate a...
The railway transportation safety system is a complex dynamic system with spatio-temporal characteristics. Taking railway line section as the research object, we propose a new cellular automation (CA) model - a safety system model for railway (SSM-R) - to simulate the railway safety. In the proposed CA model, we consider a railway line section as a cell and the neighbouring sections as the neighbors,...
The multi-agent system, which combines the cellular automata model, is of benefit to the simulations of large-scale events. Cars' movements were simulated using cellular automata model and their variability was introduced by superimposing agent. There were two submodels which based on the combined model. The first submodel simulated cars' movement in a park. The other submodel was proposed to simulate...
