Optimisation of a road construction using 3D visualisation

Abstract

The main purpose of this work presented in this paper, is the possibility to optimisea road construction using visualisation in 3D, in a scale 1:1. With virtual realitytechnology, we can visualise the whole road and the environment around. Therefore thepossibility to control the position of traffic signals, SOS telephone cabs, noise-protectionroad walls, safety exits, tunnels height or eventual bridges during the virtual visit of theroad. In the same time, we can control the visibility of the road by driver, from start till theend of the road. Doing this, we can help architects, technicians and civil engineeringgroup to modify their plans before they start to construct the real road.In this sense, we can contribute to make the work properly from the beginning,instead of doing several interventions to modify the road that are usually done once theroad is over. Of course, the cost of such interventions is very high and in the same timethe traffic is stopped.Concretly, we realised the A5 highway application. Besides the modelisation withtextures and visualisation of the road, we added the interactivity in real time through adriver of a virtual car. This application run very well, presenting a high degree of virtualreality.
