Background

• Long Range Transportation Plan for the
  Gainesville Urbanized Area
• Urban form scenarios
• First of its kind in Florida

3
Urban Form Scenarios
4
The Process

• Community visioning
• Translate visions into population and employment
  allocations ZDATA
• Evaluate using travel demand model

5
Population Allocation
6
Employment Allocation
7
Lessons Learned

• Manual allocation is tedious and time consuming
• Model was not sensitive
• Are we really capturing the vision?
• Urban form is more than population and employment

8
The Solution
CorPlan

Eastern Planning Initiative

• Thomas-Jefferson Planning District Commission
• Charlottesville-Albemarle (Va.) MPO
• 50 year vision for transportation and land use
• Sustainability accords
• Alternative futures

The 50-Year Vision

• Community Plans
• (How will we live?)

• Regional Plan
• (Where will we live?)

Implementation Strategy (How do we get there?)

How will we live?
TJPDC Sustainability Accords

What makes a place a place?

• Open space
• Types and proximity of activities
• Size and character of buildings
• Size and character of streets
• Internal and external connections
• Location of parking

• Focal point
• Greater mix of uses
• Human scale
• Transportation options
• Better use of open space

Existing Development
790,000 total acres, 160,000 developed
35
Local Comprehensive Plans Assume 2020 Horizon
Most new development in Louisa, Fluvanna, Greene
Plans
Over allocation of commercial and industrial land

36
Dispersed Scenario Business as Usual 2050
Horizon
All new development is suburban development
160,000 existing, 120,000 new, 280,000 total
acres developed
15 of farms and forests lost
37
Nodal Scenario From Workshop
All new development is urban / enhanced suburban
160,000 existing, 60,000 new, 220,000 total acres
developed
5 of farms and forests lost
38
CoreL Scenario From Workshop
Most new development is urban
5 of farms and forests lost
39
CoreM Scenario From Workshop
Variation of CoreL
5 of farms and forests lost

Dispersed Scenario Transportation Improvements
Extend US 29 Bypass
Widen existing roads
41
Dispersed Scenario Transportation Results
1billion invested in by-passes and wider roads,
not transit
16 million miles driven daily
44 of miles driven is congested
42
Nodal Scenarios Transportation Improvements
Urban Transportation Network
Priority Transit
Boulevards
Bus Rapid Transit
Light Rail Transit
43
Urban Transportation Network Mile Grid of
Boulevards
Community elements are combined to build
approximately square mile communities
High frequency bus routes along all boulevards
and most avenues
B
A
C
Avenues are major streets within communities and
connect with boulevards

• Boulevards are spaced mile apart to
• Connect communities
• Define community boundaries
• Distribute traffic, keeping volumes low on each
• Provide convenient transit access

Neighborhood streets are minor community streets
and connect with avenues
44
Boulevard Design Characteristics People Friendly
Streets
Buildings brought to street for enclosure /
interest
Landscaped medians provide crossing refuge
Streetscape
On-street parking protects pedestrians
Bus amenities include shelters and by-pass lanes
45
Boulevard Functions Multimodal Orientation
Max speed 35 mph Max daily volume 30,000 Max
distance to transit half mile
Transit
High frequency bus transit service is provided on
each street. Bus amenities, such as pull-outs
and shelters are provided. Bus priorities, such
as by-pass lanes and traffic signal preemption
are also provided.
Walking and Biking
Sidewalks and bike lanes are incorporated.
Landscaped medians are provided and bulb-outs are
build at each intersection and most mid-block
sections. Buildings are brought to the street.
Travel speeds for cars are 35 mph or less.
46
Urban Transportation Network Reduces Auto Travel
and Congestion
The proximity of activities within communities
promotes walking and transit
B
A
C
The proximity of communities to each other makes
auto trips shorter
The roadway grid makes travel more efficient by
providing more travel paths between communities
47
Nodal Scenario Before Priority Transit
Half billion invested in roads, local transit
12 (vs.16) million miles driven daily
29 (vs. 44) of travel is congested
48
Nodal Scenario With Priority Transit
Half billion invested in roads, local transit,
half billion in priority transit
11 (vs.16) million miles driven daily
25 (vs. 29) of travel is congested
Priority transit not a short term need
