The paper deals with microscopic modeling of the traffic flow using cellular automaton in the Tunnel Simulator based on PLC. Model with lane changing logic is implemented in the SCADA visualization screen of the tunnel with unidirectional two-lane traffic. Tunnel Simulator is able to simulate unexpected events in the road tunnel such as fire, so vehicle type is also included in the traffic model to...
This paper deals with models of air pollution inside a tunnel tube. Various gases are emitted by combustion engines. They consist largely of oxides of nitrogen, carbon monoxide, steam and particles (opacity). Since each tunnel is unique, the design of the model must be realized for the particular road tunnel. Data measured in the control center of the tunnel is used to create various models and to...
This paper deals with the evacuation from a road tunnel. We have focused on the possibilities of using technological equipment for evacuation of people. The first part deals with the definition of the evacuation issue. The evacuation of people comes when an accident is found. It consists of informing people in a tunnel and providing possibilities for evacuation. At this moment, the technological equipment...
The application of new technologies on railroad crossings goes along with many questions, which answering should forego the implementation itself. The paper presents basic problems of crossings and the classification of generic railroad crossings according to the European Railway Agency. Therefore the goal of this paper is to present the current state and prospects in the field of railroad crossings...
