Road geometric design is strictly related to the level of a road traffic accident. Numerous
accidents are caused by the inappropriate design of road geometric. This study aimed to
determine the relationship model of road geometric parameters and accident rate. Jember–
Banyuwangi national road was chosen as a location of the study. Five independent
variables named the radius of bend, the degree of curvature, super-elevation, widening of
the curve, and side freedom were used. Meanwhile, there are three dependent variables …
