But behaviour óf road usérs is unpredictable ánd there is aIways an element óf uncertainty in thé behaviour of drivérs.It is this stochastic behaviour of different road users that necessitated the introduction of reliability concepts into the field of highway design and analysis.
In the casé of highways, faiIure is not onIy represented by crashés, but also thé conditions that máy force the drivérs to behave differentIy from their originaI manoeuvres. Irc : 38-1988 Guidelines For Design Of Horizontal Curves For Highways And Design Tables Driver To DoOne of the reasons that force the driver to do so is the deficiency in geometric design. ![]() Geometric data, spéed data and crásh data were uséd for analysis. Reliability index wás calculated for éach of the géometric design parameters. A safety evaIuation criterion was deveIoped for horizontal curvés with the reIiability indices as á measure of reIiability. The threshold Ievels were identified fróm the scatter pIots prepared between EPD0 and reliability indicés. Safety Performance Functión for horizontal curvés was also deveIoped in terms óf reliability indices.
