Improving Intersection design Practices KYSPR 09-380

OBJECTIVES: The obj ective of this project is to develop a process for a complete and systematic evaluation of intersection design altematives. The aitematives should address operational and safety effici ency for all roadway users. Intersection alternatives should consider both geometric design and operational elements, such as number of lanes, auxilial)' lanes, lane usage, and traffic control. The traffic control options should evaluate the use of sign, traffic signal, and roundabout options and detenn ine the most appropriate control for the palticular location. This will allow for a more appropriate and properly customized design for each section and avoid the use of "standard or typical" designs. Moreover, this approach will provide a properly justified and documented decision process based on sound engineering judgment that cou ld become palt of the design file for the project.
