| Abstract | Considerable researches have been carried out in the recent years for the roads safety with descriptive statistical analysis in Thailand. However, there is sill lack of analysis to find how each of the causative factors together affects the accident. As far as the author is aware, there has not been any research about the prediction model of accident for the highways of Thailand. Hence this research intends to add to this gap and hence interpret the problem of road safety. The Poison and Negative Binomial regression models were developed incorporating available geometric data, month, exposure etc. The explanatory variables used were Average Annual Daily Traffic (AADT), length of road section, Heavy vehicle (HV) percent, month, median, availability of shoulder, number of access, intersections, curves per km, amount of rain fall. Maximum Likelihood method was used with Statistical Package for the Social Sciences (SPSS) for the estimation of parameters. Poisson regression models were selected for the accident, injury and property damage with the total explained variation (RD²) 0.30%, 0.33%, 0.30% respectively while Negative Binomial regression model was selected for the prediction of fatality with RD² 0.19%. The developed models were used in the identification of hazardous locations. The road sections with high number of traffic volume, absence of shoulder, large number of access per km were found to be hazardous. |
