Experimental-Numerical Study of Indexation of Scenic Road Vertical Alignment in China

The vertical alignment design method of road in scenic spots does not evolve enough along the vehicle’s rapid variation. Values maximum longitudinal slope (MLS) and longest length (LSL) applicable to roads used by environmental-friendly vehicle (EFV) are provided. To compensate for this shortage, a multibody dynamic model uphill traving is built, providing static equilibrium state balancing process typical vehicle. MLS LSL values obtained based on through numerical simulation, considering EFV, velocity loss (MVL), ideal (IVL). Field experiments verifying results also carried out Huashan Mountain, Cuihua Mountain National Park, Taiping Forest using two EFV types. research vary from 7.8% 10.2% 200 955 m, respectively, both larger than corresponding current criteria. According verification results, relative errors climbing 0.0104 0.0205, showing model’s accuracy further proving practicality obtained. lay foundation establishing scenic-road method.
