Traffic Access Management

University of Tennessee CTR
Nashville, TN

The planning-related educational objectives of the Traffic Access Management workshop include:

1 - The importance of managing access (30 minutes)
The workshop presents the main purposes of access management: providing access to land development, preserving safety and efficiency of the transportation system, maintaining roadway capacity over time, and providing for a standard method for regulating roadway access. Examples of these principles will demonstrate the benefits of access management.

2 - Land development and access management transportation issues (45 minutes)
The workshop reviews how the land use/transportation cycle affects transportation facility development and use over time. Participants discuss the impact of access management on traffic operations, safety, environment, and economic development. NCHRP (National Cooperative Highway Research Program) reports 348 and 420 are the source documents for access management techniques. Workshop discussion covers the importance of roadway functional classification. The relationship between trip stages and access levels by roadway type are presented.

3 – Access management policy (45 minutes)
In this section, instructors detail the access permits process and discuss access management plans. Attendees learn how to classify improvement techniques, stratify impacts, and finance access improvements. Examples will be provided illustrating how access management and comprehensive planning can work synergistically to create sustainable development patterns.

4 - Legal and regulatory approaches to access management (45 minutes)
The legal framework for access control is presented in the context of property owner’s rights and regulatory power of the state, using Tennessee’s legislative framework as a case study. Deed control and land supply control are presented as management options. The role of major thoroughfare plans, regional planning regulations and local planning regulations in access management are discussed. Information on development cost impacts, driveway regulations and design/operation options is provided.

5 - Access design for roads and streets (60 minutes)
This section presents roadway cross-section design and its influence on access management. The importance of spacing between property access points and its relationship to safety is discussed. Attendees learn about median design alternatives to access control. The advantages and disadvantages of frontage roads are also discussed. The impact of access management on traffic signal operations is thoroughly explained. Several examples illustrate the concepts covered in this section.

6 - Access design for interchanges and intersections (60 minutes)
In this section, attendees learn about intersection design principles and the importance of the intersection functional area to access management. Instructors present guidelines on corner clearance as a tool for site development planning, and explore left-turn and right-turn treatments. Standards from Florida DOT exemplify policies for limited and controlled access facilities. Participants discuss interchange design.

7 - Site access design (30 minutes)
This section demonstrates how the design and arrangement of developments create planning opportunities for enhancing access management. Instructor discusses development access types and give guidance on driveway design. Best practices for site traffic circulation are explained.

8 - Public involvement in access management (45 minutes)
A detailed procedure on generating public involvement in the development of an access management policy is discussed in this section.

A brief summary of the day activities ends the Traffic Access Management workshop.
