Case Study

MDOT

Outline

• Project Purpose

• Scope of Project

• Significant Impacts from Katrina

• Major Impacts to Traffic

Summary

• Coordinated effort with City and MDOT accomplished implementation of many of the Access Management recommendations

Common Reasons to Consider Exceptions

• Impacts to the natural environment

• Social or right-of-way impacts

• Preservation of historic or cultural resources

• Sensitivity to context or accommodating community values

• Construction or right-of-way costs

Risk Management Characteristics

• Explicitly addresses uncertainty

• Based on the best available information

• Part of the decision-making process

Traffic Operational Analyses (TOA)

• A TOA will be required for all development projects that are expected to generate 200 or more vehicle trips per day and for which a Traffic Impact Study (TIS) was not completed.

• A TOA will be required for any development project for which changes in land use are intended after the completion of a TIS or TOA, if enough additional vehicle trips are being generated beyond those accounted for in the TIS or TOA, as determined by the County Coordinator.

Proposed Changes & Improvements

• Use the county assessed value as the baseline value for calculating the difference vs. going through a costly and time consuming appraisal process.

• Charge only a percentage of the determined value for changes to residential (less than 10 dwellings) and farm access.

• Charge full amount of determined value for commercial, retail, etc…

• Charge an administrative fee for processing requests.

Outline

• What is a CFI?

• Why consider a CFI?

• Access Management Issues at a CFI

• Potential Access Solutions

• Questions Comments

Potential Access Solutions

• Inter-parcel Access

• Service Roads

• Partial Median Openings

• Right-In Only Driveways

• Right In-Right Out Driveway on CFI Leg

• U Turns

• Purchase Access Rights

• Relocate/Add Driveway

Approach/Methodology

• Educate the Businesses

  • What is Access Management and how can it help?

  • Public Meeting

  • One-on-One meetings with business owners

• Identify opportunities and obstacles

• Identify priorities

• Develop a strategy for implementation and ongoing coordination

Well-designed Modern 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 & Safety Characteristics:

• Driveway and intersection spacing versatility

• Geometric flexibility (properly designed)

• Less queuing

Topics

• New Jersey Jughandle Intersection (NJJI)

• Displaced Left Turn Intersection (DLF)

• Median U-Turn Intersection (MUT)

• Restricted Crossing U-Turn Intersection (RCUT)

Summary

• All unconventional intersection designs are conceived to take advantage of the local traffic pattern

• Their main design objectives are to improve LOS of critical movements, maintain or improve overall safety at main intersection, and generate tolerable delays to non-critical movements

Outline:

• Introduction
• Crash Analysis
• HSM 2010 Predictive Method
• Case Study
• Discussion

Site-specific EB Method

• Combines observed crash frequency with the predictive model estimate
• Reduces effects of regression-to-the-mean
• Both SPF and Crash data must be available

Chapter 12 Predictive Method for Urban and Suburban Arterials

NCHRP 15-35, Geometric Design of Driveways

Many years since comprehensive national guidelines for the geometric design of driveways

• Has been a growing emphasis on …
  
  • access management
  • designing for pedestrians with disabilities.

Issues to Address

The First Steps

• Access Management Champion
• Get buy-in from internal staff and management
• Secure funding for activities (not always required)
• Outreach
• Presentations
• Websites
• One-on-one Interactions

Next Steps (Peoria)

Three Examples from a Developer’s Perspective

• A 15 acre +/- development that was ultimately denied as they could not secure reasonable access to accommodate the site traffic.
• A redevelopment project that was ultimately approved though unable to meet any of the access management standards.
• An approval to allow additional access to support an existing development and improve on-site circulation concerns

Success

Overview of Synthesis Survey

• All 50 state DOTs contacted – Targeted key individuals with access management responsibilities at each state DOT
• 69-question survey was administered online:
• Email distribution to DOT contacts in all 50 states
• ITE Traffic Engineering Council
• ITE Transportation Planning Council
• National Association of County Engineers
• Association of Metropolitan Planning Organizations

Profiles of Contemporary Practices

Market Characteristics

• How much development can be realistically absorbed in this area?
• How will market area be sustained?
• What message will be crafted for key stakeholders?

Measures of Effectiveness

• Safety
• Market Area (Sustainability)
• Walkability
• Natural Environment

Implementation and Integration

• Public Involvement/Information
• Access Controls
• Land Use Controls
• Formative Measures/Revisiting

Design Considerations of a Corridor Retrofit

Outline

• Introduction
• Background
• Data Collection
• Intersection Analysis
• Conclusions & Recommendations

Conclusions & Recommendations

What are the big issues?

• It’s the economy!
• Access to US 72
• New connections
• Safety – truck conflicts
• Growth and traffic congestion
• Tourism/visitors

Tools for implementation

• Zoning
• Subdivision regulations (major street plan)
• Policy decisions
  
  • ALDOT – signals, median openings
  • Local agencies – urban services
• Master Plans and Corridor Management Agreements
  
  • Putting it all together

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.
