FURTHER INVESTIGATION OF TRAFFIC OPERATIONS ON TWO-LANE, TWO-WAY RURAL HIGHWAYS: RESEARCH SUMMARY. FINAL REPORT

This report summarizes the work of three separate research projects. In the first project, a microscopic simulation model was developed to evaluate the performnce of a climbing lane. The model was used to determine an "optimum" length and location of a climbing lane on a specific upgrade and also to determine general guidelines for the most cost-effective location of climbing lanes when various upgrades are considered. In the second project refinements were made to the input and output routines of the model. The model was then modified to count potentially hazardous maneuvers and combine them into a single potential hazard index. Also, a macroscopic model for traffic analysis on rural roads was constructed. Finally, the third project was directed toward evaluating the acceleration capability of five-axle trucks along grades of a gradient from minus 7 percent to plus 7 percent. An analytical model was developed to evaluate truck acceleration performance.
