Race track modeler. Developing an Iterative Design Workflow Combining a Game Engine and Parametric Design

Abstract

This paper documents the continuing development and testing of a novel digital work flow established and implemented for the design and redevelopment of formula one racing tracks. The Race Track Modeler (RTM) tool uses a game engine to simulate driving around proposed track designs. Performance data from the simulation is combined with real data acquired from analysis of vehicle mounted accident data recorders (ADRs). The output of the tool is a graphical representation of simulated stopping positions of vehicles that have lost control and left the track. This information directly informs the design of motor racing facilities, the zoning of spectator facilities, position and specification of crash barriers (if required), and surface material selection for the run-off zones (the area where vehicles are expected to stop after losing control and leaving the track). The RTM can suggest further design changes to the track geometry which are then fed back into the game engine. The project involves methods of binding analysis of design directly to geometry together with input from interactive controls. The RTM has been developed and tested during the redevelopment of Silverstone race track in the United Kingdom (figure 1) this paper documents the current state of the tool and concludes with proposed future developments.
