Contents• Patterns for Growth• Modeling Growth Scenarios• Rural Bicycle Suitability Mapping• Case Study: Houston, Mississippi

• Rural Growth• What to do when it

happens?• How do we plan for

growth?

Patterns for Growth

Method

Patterns for Growth• Current for rural areas

• New development leapfrogs to greenfields

• No pedestrian connections

• Transportation Efficient Growth• New development is

next to old• Pedestrian/bike

connection

Method

Patterns for Growth• Low Density, Single

Use Zoning• Under 7 dwelling

units per acre• No mixed use• Autocentric

• Higher density, multi-use zoning• 7 dwelling units per

acre and over• Mixed use• Pedestrian

Method

Modeling the Scenarios• Current build-out

of growth• Assumes,

greenfield, low density development

• New pattern of growth• Assumes

development in city core, high density

Method

• CommunityViz• ArcGIS based

software• Allows building of

land-use scenarios

• Can measure impacts such as:• Population• Labor force• Dwelling units• Energy use• Tax revenue

Modeling with CommunityViz

Method

• All commercial and residential properties geocoded

• Zoning and natural hazards are mapped

Modeling with CommunityViz

Method

• Current Build Out• CommunityViz

“builds out” using existing zoning as a guide

• Build out maps produced showing households and density based on continuing existing conditions

Modeling with CommunityViz

Method

• New developments conforming to transportation efficient growth principles are placed in model

Modeling with CommunityViz

Method

• New Build Out• Build out

maps produced showing households and density based on continuing existing conditions

Modeling with CommunityViz

Method

• Identify safe and usable roads for rural cycling• Identify

roads that can easily become bikeways

Bicycle Suitability

Method

• Rural Criteria• Shoulder

width• Traffic

volume• Posted

speed limit• Pavement

surface quality

Bicycle Suitability

Method

• Need easily available data• DOT

• Traffic volume• Posted speed

• Google maps• Shoulder

width• Pavement

conditions• GIS

• Road profile
