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. Information to be compiled for this synthesis includes: (1) Examples of local policies, zoning, subdivision, and site plan documents and other local policies that address access management. (2) Feedback from DOTs and selected local agencies on effective practices for the application of cooperative access management. The scope includes: (1) A literature review to document common themes and elements of successful access management ordinances and policies. (2) An initial screening survey of all State DOTs to identify the agencies that have corridor-based access management agreements with local agencies. In addition, those DOTs that have successfully worked with local agencies on access management issues will be asked for local agency details and staff contacts for follow-up. (3) An in-depth survey of selected local agencies will be conducted to collect relevant information and documents. In addition, interviews with representatives will be conducted to ascertain their agency experience and lessons learned from their application of access management. (4) Case examples of access management by local agencies will be developed and provided in the Synthesis. (5) A concise final report of the findings (literature, survey findings, case examples, and information gathered) from this project will be developed. Sample documents obtained during the conduct of this study will be included as appendices. (6) Knowledge gaps and suggestion for research to address those gaps will be identified.
