Determining of black spot location in Purbalingga Regency using road geometric approach

Traffic accidents are still one of the serious problems faced by Indonesian Government. Based on traffic accident data from Corps Republic Indonesia number in 2020 is 100,028 incidents and deaths due to 23,529 people. caused several factors such as vehicles, human error road users, conditions environment. Road geometry factor that contributes high value risk accidents. One effort reduce identification handling black spot location. The purpose this research was determine locations using geometric facilities. Thus, location can be predicted before incidence a occurs through weighting parameter geometric. Research conducted arterial collector roads Purbalingga. Six parameters used locations, namely vehicle speed, lane width, shoulder pavement median drop-off (difference elevation between edge). Weighting intervals for geometrics 1 5 with interval 1. As result study, there differences ranking based equivalent method approach. further coefficient each combined equipment
