Remedial Safety Treatment of Accident-Prone Locations

Martha Leni Siregar, Tuti Alawiyah, Tri Tjahjono



prone locations refer to locations having or susceptible to having, a greater
than average number of accidents which are represented by outstanding figures
of repetitive accident occurrences along the roads. Any appropriate application
of remedial safety treatments will require ­an in-depth study to find the
accident causations and the possible contributing factors. The present study
adopts the combined approach of Systems Theory which proposes that accidents
are the result of maladjustments in the interaction between the components of
complex systems, and the Causal Accident Theory which tries to find the real
causes of accidents by probing the events leading to each accident in detail.
The case study was conducted at Gringsing Roundabout in Central Java and the
intersecting roads, the data of which reveal a high frequency of
accidents.  The data were analyzed using cross tabulations to produce
first-hierarchy and second-hierarchy accident causations. Results indicate that
geometric features, as the predominant factors, lack compliance with the
standards. The remedial safety treatment therefore focuses on geometric
redesigning of the roundabout in compliance with geometric standards and
traffic demand. A major change, in conjunction with other hazard reduction
schemes along the roads, is also proposed to the existing roundabout. The
proposed changes are expected to mitigate or remove the possible accident
causes, thus reducing accident occurrences.
