Accident risk analysis of road geometric components using functional worthiness approach

The geometric design of the road should be based on criteria and requirements contained in guidelines. However, limitations natural conditions considerations during make not ideal according to Deviations from guidelines may indicate that is standard has potential accident risk. This study intends analyze risk accidents aspect road. purpose this find out how level due approach used analysis functional worthiness where each component compared with field data collection method was carried by measuring components road, which included horizontal vertical alignments. location national roads Jambi Province area a total length 1.095 km. For purposes, divided into 82 segments. analytical multiple regression various statistical parameters related these results. modeling results show coefficients for variable alignment, combination alignment are 0.248, 0.349, 1.170, respectively. While constant equation model 3.366. greatest value contribution variables coefficient 1.170. tests relationship between strong linear
