Synthesis of Information Related to Highway Practices. Topic 50-05. Incorporating Access Management into Local Ordinances and Planning

Managing the access from abutting properties to arterial roadways is a highly effective strategy for reducing crash frequency and improving the operational performance of the roadway. Access management tools that state departments of transportation (DOTs) are using include the use of highway design features (e.g. constructing restrictive medians) and where possible, using their permitting regulations to control driveway locations, spacing, and design. However, DOTs do not have the authority to control local government land use decisions, including zoning and site design ordinances. It is these land use and design decisions that ultimately lead to the location of access points to the adjacent roadways. Some local agencies are recognizing their role in providing safe and efficient roadway access, and are seeking to improve their subdivision, zoning, and site design ordinances to address key access management issues of driveway and intersection location and design. Unfortunately, they are finding limited information in the literature to assist them in addressing these key access management issues. The objective of this synthesis is to document local zoning ordinances, site design regulations, and other practices that support access management. The synthesis will benefit local governments wishing to incorporate access management into their land planning processes. The report will also benefit DOTs in working with local agencies on issues related to access management.
