Abstract:

Relationships between truck accidents and selected geometric characteristics of interchanges are examined. Datasets containing information on truck accident at interchanges, traffic exposure and selected geometric characteristics are analyzed with an emphasis on interchange and ramp configurations. Most of the data in the report was obtained from the Washington State DOT, with limited data obtained from Colorado and California. In order to assess the impact of merging and diverging maneuvers on safety, the limits of ramp influence zones expressed in terms of accident frequencies were defined on the main line alignments.
