Study of Relationships between Skid Resistance and Traffic Accidents |
| บทคัดย่อ (อังกฤษ) |
One of the key elements of road safety is skid resistance. Particularly slippery surface conditions affect the risk of road accidents. This research aims to study the relationship between road accidents are caused by the friction surfaces. Historical accident data, friction data and traffic volume of road network of department of Highways 19 route and 386.350 km distance. In this analysis, divided total road into small road section 500 meters intervals and a minimum in the friction block. Then calculate the wet accident rate. Regression analyses were use in the analysis. The results are
skid resistance decreased as wet accident rate increased and decreased as skid resistance increased .Then start on the static friction reaches a certain value. Bend have the accident rate highest coefficient of regression (R2) was 0.388, Single carriageway non-event, All the road, Dual carriageway nonevent, and alignment R2 were 0.280, 0.249, 0.230 and 0.122 respectively, and the threshold Investigation level (IL) for Dual carriageway non-event and alignment have IL were 0.30 . All the roads and Single carriageway non-event were 0.35. and bend was 0.40. The results can be used as a guide to determine the detection threshold of the friction surface of the country.
