Method to provide simple tool for combination vehicle dimensioning
At the moment, there are 49  High Capacity Transport (HCT) combination vehicles in Finland operating in the public roads in varying road conditions under special permit granted by the traffic safety agency Trafi. Ensuring traffic safety of longer and heavier HCT combination vehicles is essential, when designing, manufacturing or operating the said vehicle combination. Traffic safety of a planned vehicle combination needs to be proved before the combination vehicle can be used in the public roads. Proving can be done by experimental measurements after producing the planned combination vehicle, which can be costly if the vehicle combination is proven not to have required stability. Simulation models can be used to study the stability of combination vehicle in the design phase, but for a transport company the tools and personnel required to operate simulation tools can be too expensive. In this paper we propose a simplified way to provide a model to study the lateral stability of a combination vehicle with spreadsheet calculations.
