Experience-Based Park Access Model
Bringing people to parks
and
parks to people.
Experience
Access
Level of Service should consider:
- Experience
- Does the location provide a core experience?
- Opportunities for socializing
- Playground
- Open play
- Walking or riding a bike
- Does the location provide a core experience?
- Access
- How far are citizens from core experiences and how can they access them?
- Network access
- Local variations in access to park experiences
Modeling the Park System
Core Experience
Park Access Points
Raleigh Population
Census Blocks
Route Access
Transportation Network
Level of Service Metrics
Accessibility
1.29 mile network service area
By Census Block:
- Distance to closest park
- Accessible parks per person
- Accessible park acres per person
Level of Service Tools
Network Distance to Parks Tool
Census Block Centroids

Routes to parks within 1.29 mi
Step 1: Generate Routes from Census Blocks to Parks

Goal
Increase LOS by improving bike and pedestrian accessibility

Blocks for Analysis Tool
Census Block Centroids
Parks
Census Block Centroids - Park 1
Step 1: Get Census Block Centroids within 1.29 mi of each park
Census Block Centroids - Park 2
Census Block Centroids - Park 3
Census Block Centroids - Park #
Distance to Park Tool
Census Block Centroid
Transit + Greenway Network
Park Access Points
Closest routes to park
Step 2: Create closest route from each Census Block within 1.29 mi of each park
Prioritization Analysis Tool
Closest routes w/ circuitry scores & ped safety scores
Wake County Vulnerability Data
Parks w/ ranks for circuitry, ped safety, and vulnerability
Step 3: Calculate Criteria and Score Parks
Parks
- Population: 748
- Safety Score: 10th worst
- Population: 3935
- Safety Score: 62nd worst
- Population: 5287
- Circuitry: 4th worst
- Population: 10,059
- Circuitry: 20th worst
Looking forward
- Key driver for park development, land acquisition & capital improvement projects
- Scoring: Rank -> 0-based scores
- Make the model accessible
