Description

Accidents on bends in open country result in around 2000 deaths every year,a quarter of all deaths due to road accidents. They are a major safety stake.

While driver error is usually the underlying reason for the accident, thecharacteristics of the road infrastructure also play a significant role in theevents leading up to the accident. Conversely, a consistent road geometry andappropriate signalling ease the task of the driver and dramatically reduce therisk of driver error. Treating side obstacles can also reduce the severity ofinjuries when a vehicle leaves the carriageway on a bend.

This document provides design engineers and planners with all theknowledge they need in a condensed form to improve the safety of bends onmajor rural roads.
