Presentation Outline

• The following will be provided during this
  presentation
  
• 1) A working knowledge of Access Management
• 2) How to apply Access Management techniques 3)
  What ODOT is doing to support and promote
  Access Management processes and techniques

3
Access Management can provide...

• a more efficient way of dealing with problems
  associated with traffic congestion and safety
  caused by motorists turning at driveways and
  intersections.

4
Access Management

• Access

• Mobility

5
Functional Hierarchy
All highways, roads, and streets form a
hierarchy...
they may serve traffic mobility, land access, or
some combination of the two

Land Use and TransportationThe Connection
Highways provide access to land
Land uses generate trips
Source Florida DOT
To manage traffic both land use and
transportation strategies are needed
7
Access Management and Development
Access Management does not govern the type or
intensity of development Intent - to manage th
e way development accesses the local street
system No substitute for growth management
Preserve the Integrity of the Main flow of
Traffic While Providing Access to Developments
8
Application of Traffic Engineering and Roadway
Design Principles
Limiting the number of conflict points
Separating conflict areas Reducing interfer
ence with through traffic Providing adequate o
n-site circulation and storage.

Access Management Defined
A process to maintain the safety, capacity, and
speed of traffic on the public road system while
providing necessary access to adjacent land
development.
15
The Principles of Access Management
Principle 1 - Limiting the Number of Conflict
Points Principle 2 - Separating Basic Confli
ct Areas Principle 3 - Reducing Interference
With Through Traffic Principle 4 - Providin
g Adequate On-Site Circulation and Storage

Effective Access Management
What to Avoid
What to Implement
28
The Situation in Ohio Prior to 1996

• Inefficient Traffic Flow and Congestion
• Ineffective Driveway Permitting Process
• No Uniform Approach to Access Issues
• Varying Standards and Expectations

29
What ODOT is Doing
Ohio's State Highway Access Management Manual
Common Ground for Permitting Process
Statewide or Local, Comprehensive Program
Set of Uniform Standards, Regulations, and
Criteria Fair and Equitable Treatment for All
Access Categories Applied to State Highway
System (sections outside municipal corporation
limits)

Access Management - Something for Everyone

• Benefits of Access Management
• Developers, ODOT, local governments,
  and general public
  
• Goal is a safer, more efficient roadway system
  for the traveling public.
  
• Awareness of the importance of Access
  Management techniques
  
• Preserving tax payers' investment
• Safety coupled with cost savings make it an
  issue that deserves more attention, emphasis and
  use.
  
• Access Management can create a win-win
  situation for all involved.
