This document summarizes a road safety audit and crash reduction workshop held in Bandung, Indonesia. It discusses the Road Infrastructure Safety Management (RISM) approach of creating self-explaining roads and forgiving environments to reduce crashes. The crash reduction process involves collecting and analyzing accident data, identifying high-risk sites, conducting inspections, producing reports with countermeasure recommendations, and implementing improvements. Three key crash countermeasures discussed are providing sealed shoulders, delineating road alignments at curves, and marking hazards like narrow bridge walls. The workshop aimed to reduce crashes in Indonesia by applying these road safety principles.

- 8. Road Infrastructure Safety ManagementThe principle on which RISM is based is to provide "self-explaining roads and a forgiving road environment"8
- 9. A self-explaining road ....Giving drivers good information about the road ahead makes the driving task easier, enables drivers to make better choices and reduces the risk of an accident. This is the essence of a self-explaining road. 9

A forgiving road environment is about constructing flatter batters and side slopes, covering drains, marking hazards which cannot be removed, providing safety barriers where there are steep slopes, etc., so that if a vehicle leaves the road or its lane, the risk of a serious or fatal accident is reduced. 10
