title: Traffic accident mapping in Bangkok metropolis: a case study.
abstract: Results from an analysis of traffic accidents from a study of the police records of four police stations in the Bangkok metropolis are presented. The main emphasis in this study was put on the development of a measure for traffic accident density. The traffic flow was estimated at the various study locations by trained experts. By relating the frequency of traffic accidents found in the police records to the independently estimated traffic flow, a measure for traffic accident occurrence, the traffic accident density, was constructed and estimated for the 47 areas in four study locations. The spatial risk structure was estimated and three risk groups were identified. Each area was classified into its associated risk group, and traffic accident maps for the four study locations in the Bangkok metropolis are provided here. The implication for prevention strategies is discussed.
