Description
Summary:Traffic volumes and congestion continue to increase on arterial roads. Safety and performance on those roads are continual concerns. Transportation systems must be evaluated on an ongoing basis to ensure that people and goods can be moved as efficiently and safely as possible. Safety and performance indices provide a method to numerically measure given data about a system so that comparisons and rankings on safety and performance can be made as objectively as possible. One of the sets of tools that have proved successful in improving the safety and efficiency of arterial roads are access management techniques. To determine which roads can most benefit from access management techniques, a prioritization process was developed to guide decision makers in the implementation process. Recommendations were given in the form of a decision tree classifying existing or future road segments into subcategories based on volume, signal spacing, adjacent land use, and other criteria. The objective of this paper is to document the steps followed to develop a performance index-based prioritization process to target arterial roads that would benefit from the implementation of access management techniques. Using the results of the research, decision makers can better determine which sections of roadway may benefit from controlling driveway access, installing raised medians, providing future planning, or looking to a solution other than access management.
