| 摘要： | The main goal of this project is to improve the safety of six-lane divided roadways in the State of Florida by mitigating the high crash rates on these roadways (as compared to four-lane divided roadways). To attain this goal, the overall objective of this project is to evaluate roadway and operational factors influencing the high injury and fatality rates on six-lane divided roadways. Detailed analysis of geometric and traffic data collected from the archives and in the field will be undertaken to establish the correlation between these factors and injury and fatal crashes. The major outcome of this research project is expected to be the development of roadway safety models that can be used by planners, designers, and engineers to improve highway design and maintenance in order to promote safety of six-lane divided roadways. / NOTE: Final rept. / Supplementary Notes: Prepared in cooperation with FAMU/FSU Coll. of Engineering, Tallahassee.
