The forced vortex equation, based on the cross-stream inclination of a flow surface as it passes through bend, is common approach to estimating debris velocities. Here, we present preliminary results study superelevation and correction factor k , used adapt equation flows, data from Illgraben torrent in Switzerland. definition radius curvature, calculation velocities, not found exercise large i...

With the increased presence of trucks on roundabouts, the issue of overturning has become a concern. Although some geometric, vehicle, and loading factors have been connected to rollover, the safety performance of roundabouts built on high-speed roads is not well understoo...
