Thermal control of heavy vehicles - System design and impact on tunnel projects

Abstract

This master thesis examines the possibility of implementing a thermal control for heavy vehicles on the north side of the new undersea tunnel of Rogfast. The safety aspect is the reason for implementing, and it will be the first of its kind in Norway if built. An automatic control is wanted, without the presence of personnel, which is not the standard for similar controls in other mountainous countries. It was therefore developed flowcharts describing different possible ways to execute such a control. These flowcharts served as a base when general solutions later were made for the different alternatives, including plans over signing and marking necessary. These general solutions were made such that other similar projects also can make use of them, and therefore only need small changes according to the projects parameters. Based on these general solutions, the area for the Rogfast project was examined, and the solutions most fitting to the project was chosen for further work. These solutions were modelled and further narrowed down to two final proposals that also include plans for signing and marking of the area. The software s used to make the different designs was AutoCAD and Novapoint. Finally, a small economic analysis was conducted. This to examine the possible positive impacts a control of this kind could have on a project.
