Cellular automaton traffic flow model with vehicle type and number of persons

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 specify the heat release rate of the fire for car, van, bus and truck fi re scenario. Number of persons in the vehicles and location of the persons in the tunnel are planned to be used as the input for the model for evacuation time estimation.
