Geometric Treatments for Reducing Passing Accidents at Rural Intersections on Two-Lane Highways. Volume 1. Final Report

摘要

Comprehensive analyses of accident, geometric, traffic control, and volume data collected at 1,028 intersections located in 32 townships in Michigan were conducted to identify passing accident problems at rural intersections on two-lane highways. The feasibility of using geometric design treatments to reduce the number and severity of intersection-related passing accidents was examined through cost-effectiveness evaluations. A set of guidelines is presented for evaluating the appropriateness of using a geometric design treatment for a site-specific passing accident problem. Recommendations are given for using the computerized accident data base to identify major rural intersection accident problems and to explore the effects of alternative countermeasures.
