Developing Models of Road Tunnels with Petri Nets

Abstract

This thesis aimed to develop a mathematical model using a Petri net to simulate the traffic flow inside the road tunnel. The purpose was to create a single-lane tunnel that could simulate the flow while also including an event, which slows down a vehicle to cause congestion. The program uses modules to divided the tunnel into smaller segments and compute the vehicle distance inside these segments. Three different simulations using four tunnel segments yield an expected outcome, except for higher vehicle numbers due to the tunnel segment being too long. The program is still not usable and requires further development before put into practice.
