Amarillo Comprehensive Plan 2010

• Amarillo Comprehensive Plan
• “Essential need to safeguard the through traffic function—and capacity and safety—of key arterial and highway corridors”
• Amarillo Downtown Revitalization
• Need for Viable Truck Relief Route for Amarillo

Lessons Learned

• Listen
• Ground Hog Day
• Be Pro-Active

Frank demonstrated the Corridor Visualization Explorer - a new tool developed to easily show the effects of access management decisions on a corridor.

Avoiding the Bypass Blues: Managing Impacts on Small- and Medium-Sized Communities

Impacts of Bypass Highways on Small- and Medium-Size Communities

Florida DOT Project (2011)

Objective:  To gain insights on and make recommendations regarding how to study the possible indirect impacts of new bypass highways on land use and other considerations in Florida

Case Studies

Roundabouts Enhance the Achievement of Access Management Principles

• Maintain Integrity of Arterials
• Balance Mobility and Access
• Improve Safety
• Reduce Congestion
• Extend the life of Infrastructure
•  

Roundabout Operational Characteristics Allow for:

Development of Left-Turn Warrants for Unsignalized Intersections
TTI

Purpose of NCHRP Project 3-91

• Develop objective and clear process for selection of left-turn lanes at unsignalized intersections
• Provide guidance on the design of left-turn lanes

Conclusions

Parting Observations

• Applying AMM principles on newly developing highways will not be that difficult
• Applying AMM principles consistently on existing highways is proving to be a huge challenge, especially for the Appeals Committee
• One of biggest challenges is moving past the “we’ve always allowed two driveways” mindset

Hurdles Yet to Overcome

• The LPA Question – ?
• Developing an Access Management Practice versus an Access Management Policy

Oregon’s Interchange Area Management Plans — A 10-Year Retrospective
Kittleson and Associates

Conclusions

• A powerful planning tool
• Proactively addresses land use, access, and design issues
• Public process and development techniques need to be naturally transparent
• The IAMP can formally or informally be applied to all jurisdictions

Network Planning and Development Strategies for Access Management

The lack of access control along arterial highways has been the largest single factor contributing to the obsolescence of ….an entire generation of new arterial facilities built only a short while ago.

“The ultimate goal of this ambitious program is to transform Abu Dhabi into the sustainable capital of the Arab world.” The Abu Dhabi Department of Transport (DoT) was established in 2006 – combining agencies of Aviation, Maritime, Public Transport and Highways They are creating about 25 manuals – Current Status Change in Framework • Started with Manual (2010) – following TRB AM Manual, like they follow the Green Book, but directed switch to directive language – regulations. • May produce a training manual in the future.

Objectives
• Determine the safety and operational benefits of superstreets for NC motorists
• Fulfill the need for capacity and level of service methodology

NO AUDIO AVAILABLE Outline • How can we incorporate AM and transit needs. • Goal can we improve access plans for all types of transit systems. • Bus Transit o more difficult to achieve access restrictions o access creates unique issues.

Access Management Regulations • Roadway Classification • Access Management Standards • Permitting Retrofit Projects • Cost is borne by the public • Benefits accrue to the public Conclusions • B/C criteria are applicable to retrofit projects • Warrants for permitting should be lower than for retrofit
