| 摘要： | The objective of this research was to develop statistical models for defining the relationship between traffic accidents and highway geometric design elements and traffic volumes for interchange ramps and speed-change lanes. The data base used to develop the models consisted of data for interchange ramps and speed-change lanes in the State of Washington and was obtained from the FHWA Highway Safety Information System. The statistical modeling approaches used in the research included Poisson and negative binomial regression. |
