MOTOR VEHICLE ACCIDENTS IN RELATION TO GEOMETRIC, AND TRAFFIC FEATURES OF HIGHWAY INTERSECTIONS: VOLUME III--APPENDICES

This volume, the third of a three-volume final report, provides supporting data regarding the study area, sampling and data-collection methods, analysis methods and data-processing techniques, and study results obtained in Volume II. The executive summary for managers is presented in Volume I, and the overall study results are analyzed in Volume II. A relatively detailed on-scene inventory of the geometry, other design features, and traffic counts for 558 intersections coupled with police reports on the 4372 accidents that occurred there during the three-year study period were used in the analysis. Forty-one accidents were studied in detail by a multidisciplinary team to determine causal factors and to evaluate the effects of federal safety standards on intersection-accident incidence and severity. Six intersection design features were demonstrably accident related--sight-distance obstruction, street-name signs, left-turn storage lanes, raised-marker delineation, bus-loading zones, and routing and multiphase signalization. Accident countermeasures based on the influence of these six factors are recommended.
