Developing Models of Road Tunnels with Petri Nets

Abstract

According to the survey about 50% of human deaths occurred due to road accidents among which some of the extreme accidents happened in tunnels. Norway is well known for its highest road tunnels length with nearly 900 road tunnels on both national and country side. The department of Norwegian Public Roads Administration has therefore decided to do a research study on different traffic accidents based upon police reported accidents. This thesis focus on an important aspect of the tunnel safety by developing model of road tunnels with modular petri nets to explore the traffic capabilities. A novel control and sensor scheme has been implemented with the Petri net model to insure safe, control and secure traffic in road tunnels. GPenSIM is a Petri net based simulator tool that offers significant benefits to model structures. The purpose of the proposed work is to provide a cost effective measures to improved tunnel traffic security. The proposed work has been analyzed, evaluated and presented in a structured way. Future research directions are also discussed in the end.
