Research on the Efflux Angle to Emergency Escape Ramp of Mountain Roads
To resolve heavy-duty trucks side over the boxes, scraping the guardrail and other accidents when driving into the entrance of emergency escape ramp, according to studying on lateral stability of the out-of-control heavy-duty trucks and combining with their mechanical properties, this dissertation analyses the wheelpath’s geometric features when the out-of-control heavy-duty trucks rush into the emergency escape ramp from the main road, results a reasonable range to adapt the efflux angle of emergency escape ramp on our mountain expressways, and provides necessary theoretical references for the selection of the efflux angle on mountain roads.
