A fun, musical ending to the 2012 Access Management Conference.
Would you like to hear those songs again? put a note in the comments.
Here are the lyrics for Access Management – the Musical
I want to get thru (To the tune of Hello Mary Lou)
Passed me by one summer day,
Flashed those big headlights my way
And then I sat in one big traffic jam
I just want to get around
Not be stuck in this downtown
Oh no I hear a screech, slam bam and wham.

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
Development of Left-Turn Warrants for Unsignalized Intersections
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
- Purpose of Tennessees Corridor Management Project
- Project Overview & Process
- The Selected Tool: Corridor Management Agreements (CMAs)
- Reactions-to-Date & Next Steps
- Explaining CMAs to key stakeholders
- Getting CMAs approved
- Implementing the CMAs
- Establishing long-lasting partnerships and processes immune to local and state political changes
- 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 weve always allowed two driveways mindset
Hurdles Yet to Overcome
- The LPA Question ?
- Developing an Access Management Practice versus an Access Management Policy
- Functional Classification System
- Land Use Controls
- Corridor Planning
- Project Design
Where do we go next
- Complete Streets training,
- Expanding adoption to private developers getting permits,
- Training for municipalities
- Benefits of Multimodal system to AM
- Implement Guidelines
- Performance Measures
Oregons Interchange Area Management Plans A 10-Year Retrospective
Kittleson and Associates
- 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
- Review origin of current guidelines for access separation from interchange ramps
- Review recent Virginia study on the relationship between access spacing from interchange ramps and crash rates
- Suggest new standards for the optimum access point spacing
Findings and Recommendations: Access Spacing from Interchange Ramp
Oregon State University
As part of the AMAG project, Karen Dixon used a driving simulator to study the driver perception - reaction time of drivers of different ages.

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.
