Bike/Ped Planning in Metro Atlanta
– The Bicycle: A Plan and Program for its Use as a
Mode of Transportation and Recreation (1973).
– ISTEA (1991)
– Bicycle and Pedestrian Taskforce (1992)
– Atlanta Region Bicycle Transportation
and Pedestrian Walkways Plan(1993).
– Updates: 1995, 2002.
Bike/Ped Planning in Metro Atlanta
– All provided policy direction and included project lists
– Lacked a strategic vision for the prioritization of
federal funds for bike/ped in the Atlanta region.
– Projects recommended did not come together to form
a complete network.
Bike/Ped Planning in Metro Atlanta
– New Plan developed in 2006-2007
– Established a strategic focus to
integrate non-motorized planning
with regionally significant
transportation issues
– Developed a prioritization process
for bike/ped funding assistance

“Livability” Initiatives
Plan Goals and Objectives
• Written to address regionally significant issues,
strengthening the link between bike/ped and
existing regional priorities
Plan Goals and Objectives
Priority Corridors and Centers
• Roadways of the
Regionally Strategic
Transportation
System
Priority Corridors and Centers
• Regionally Significant Nodes
•
•
•
•
•
LCI study sites
Cities with population greater than 5,000
County Seats
Major transit facilities
Major “activity centers”
Priority Corridors and Centers
• Plan recognizes that full bicycle network
includes all streets
How to Measure Performance:
Conditions that Affect Cyclists
•
•
•
•
•
•
Effective Travel Width for Bicyclists
On-Street Parking Encroachments
Volume of Motor Vehicles
Speed of Traffic
Proportion of Heavy Vehicles
Pavement Surface Condition

Performance Measure:
Bicycle Level of Service Model
Bicycle LOS = a1ln(Vol15/L) + a2SPt(1+10.38HV)2 + a3(1/PC5)2
- a4(We)2 + C
Vol15
L
SPt
= volume of directional traffic in 15-minute time period
= total number of through lanes
= effective speed limit (see below)
HV
PC5
We
SPt = 1.12ln(SPP -20) + 0.81
SPP = Posted speed limit
= percentage of heavy vehicles
= FHWA’s five point surface condition rating
= Average effective width of outside through lane
Existing Conditions (2006)
• Bicycle Level of Service
• Study network of 690 miles in 18 counties
• Results for 642 miles
• Distance Weighted Average of
4.54 = Bicycle LOS “E”
Existing Conditions (2006)
Existing Conditions (2006)
•Bicycle Level of Service = “E”
Existing Conditions (2006)
•Bicycle Level of Service = “E”
Existing Conditions (2006)
•Bicycle Level of Service = “E”

Latent Demand Method
•Predicts probability of
non-motorized trips
based on proximity of
generators and
attractors...
if impedance were
removed
Latent Demand Method
• Used 2001 NHTS trip lengths for walking and biking
for:
•
•
•
•
•
Work Trips ( also used for higher ed.)
Shopping
School Trips
Social Recreational Trips
Trips to Access Transit
Existing Conditions (2006)
• Pedestrian Conditions
• Sample analysis of longitudinal conditions
at high demand nodes with
Pedestrian Level of Service Model
• Discussion of challenges of crossings, both at
intersections and mid-block locations
Existing Conditions (2006)
Existing Conditions (2006)
Pedestrian Policy Review
• PEDS Survey 2006- 6 of 13 counties had
standard sidewalk requirements in place
• Remaining counties had variable requirements
• Staff vigilance drives action, rather than policy
Bike Policy Review
• On street facilities may be included overlay
districts or other special cases
• Staff vigilance drives action rather than policy
Existing Conditions (2006)
• Bicycle conditions are very challenging
• Walking conditions are very challenging
• Policies are inconsistent across the region
Needs Assessment
• What level of accommodation is appropriate
on this class of roadway?
Needs Assessment
• Community workshops
to “find the level”
• Bike/Ped Levels of
Service “C” chosen as a
general target;
• Bike Ped LOS “B” for
high activity areas
Needs Assessment
• Recommended strategies for improvement
•
•
•
•
LOS met
Re-striping
Widen shoulder

• Strategically evaluating projects’ contributions
to regional goals requires prioritization based

• Supplement to practices of routine accommodation
and “complete streets”
• Georgia DOT has incorporated bicycle
accommodation into design for roadways of the

Promote bike/ped planning and implement bike/ped
programs
Policy Initiatives and Policy Initiatives

• Changing the mindset of planners engineers,
elected officials, public
• Will lead to better implementation of other policies
• Programs
Going Forward...
