The design of a mountain expressway includes many special road sections, such as the
combination of sharp bends and curved slopes, which may easily cause traffic accidents …

Appropriate speed selection in curve roads is the key of traffic safety during the vehicle's
cornering. Lateral instability induced sideslip and rollover are the two main accident forms in …

As it was found steep slope and sharp curve sections account for 14% of the accident‐prone
sections according to the accidents data in Chongqing. Regular design indices with certain …

The appropriate selection of speed in curve is the key of improving traffic safety. In this
paper, rollover and sideslip in road curves induced by lateral instability due to the excessive …

International crash data indicate that roadside characteristics contribute to more than half of
all roadside accidents involving serious injury or death. Therefore, research on roadside …

Because vehicles often violate the speed limit on curved roads, rollover and sideslip
accidents occur on curved roads frequently. Designing the speed limit value of the curve …

It is often meet in the process of designing the expressway in the mountainous area to
design long steep downgrade section. But the current route design specification doesn't …

Sharp curves are vulnerable sections for rollover accidents. This study was conducted to
investigate the effects of transition curve and superelevation on the critical speed and critical …

Due to limitations of topography and other conditions, the curve sections of mountain
highways are always prone to accidents. In order to improve the safety level of mountainous …

An inferred design speed (IS) is the maximum vehicle speed for which all critical design
speed-related criteria are met at a particular location, which is widely recognized as an …
