SimPRAcc - Simulation for the Prevention of Road Accidents PDF Drucken

Project type: Master Project

Students: 5

 

Abstract:

3D car driving simulations can improve traffic safety. However, creating them requires an extraordinary amount of work. In this project, we looked into streamlining the production workflow of virtual worlds for driver training. This concerns in particular road networks and facades.

 

 

Description:

Virtual reality simulations can be used to train drivers to cope with dangerous situations that would lead to injury or even be fatal in real life. On top of that, simulations can be employed to study human behavior; one may even test different options for architecture of roads or the signalling in the simulator.

However, the production of such VR worlds is a costly endeavor, with a dozen designers and programmers easily spending several months on rebuilding only a portion of a city's road network. Similar problems occur in game development, the production of 3D navigation aids, and architecture previsualization.

Together with a Bremen-based company we looked into ways of improving the production workflow, eventually focusing on the XML-based description language CityGML. It can be employed as a common data container to be used by such diverse organizations as cadaster offices, telecommunication companies, and real-estate agencies. Thus, a 3D city model can be shared by a number of stakeholders, lowering the overall production costs.

We developed support software to integrate CityGML with our partner company's VR system. This meant to take care of the highly complex XML schema, understand the proprietary, grown Unix-based VR system and its file formats, convert highly incongruent geometry data structures and organize texture image files into different layouts.
