ABSTRACT: Hairpin curve is an
accident prone location. The number of accidents on curve 1,5 to 4 times much
more than on straight road. This study aimed to evaluate the geometric
conditions on some curve that is reviewed by applicable geometric rules, to
determine the characteristics of the accidents, to determine the relationship
of modeling the causes of accidents, to determine the main factors causing
traffic accidents, and provide troubleshooting recommendations. The analysis
that is carried out are analysis of geometric condition evaluation, accident
characteristics analysis, and cross tabulation analysis. Based on the
evaluation of the geometric conditions, on all of the third curves there are
not reach the technical standards because under minimum curve radius and the
value of SMS of sample vehicle variety more than SS curve calculation speed
limit nearly reach 50%. Based on the characteristics of accidents, on the third
curves showed that the dominant factor causing accidents is human factor (70%).
The results of study relationship between curve radius and degree of fatality
indicate the value of R Square 0,859, meanwhile relationship between speed and
degree of fatality indicate the value of R Square 0,91. The sum of the analysis
showed the main factor causing traffic accidents is human factor specificly to
the speed factor and then continued by curve radius factor. Several attempts
types of treatment that can be applied is to install speed limit signs in some
specific locations, make rumble strips before entering the hairpin curves.
