Prioritizing of Access Management Rebuild Research — Taking the National Highway G205 Jiangsu Section as an Example

With the rapid economic development on both sides of the National Highway of G205, Jiang Su, China, traffic volume and congestion continually increase. As the safety and performance of these roads is a major concern, transportation system should be evaluated on an ongoing basis to ensure that people and goods can be moved as efficiently and safely as possible. In all kinds of security measures, access management techniques have been proved the most successful in improving the safety and efficiency of arterial roads. To determine which roads of the National Highway of G205 can most benefit by the implementation of access management techniques, a prioritization process was developed to guide decision makers in the implementation process. Recommendations were given in the form of decision steps distinguish existing or future road segments between access densities, signal intersection spacing, traffic accidents, access environments 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. Utilizing the results of the research, decision makers can better determine which sections of roadway could benefit from controlling and rebuilding of driveway access.
