PEDESTRIAN COMPOSITE INDEX

slide-3
SLIDE 3

The Pedestrian Composite Index (PCI) is a model developed by the Mid-Region Council of Governments (MRCOG), the metropolitan planning organization for the Albuquerque, NM area. Their PCI is an analysis using Geographical Information Systems (GIS) to measure the relationship between where pedestrian activity might be generated and where pedestrians might have difficulty moving about. Put together, this information suggests regional priority areas for investment.

STUDY BACKGROUND

  • Pedestrian Generator

− Measures areas that generate pedestrian activity

  • Pedestrian Deterrent

− Measures areas that deter pedestrian activity

PEDESTRIAN COMPOSITE INDEX

PEDESTRIAN GENERATOR - DATA USED

  • Transit Stops
  • Public Parks
  • Public Libraries
  • Elementary Schools
  • Middle Schools

  • High Schools
  • College and Universities
  • Walkable Businesses
  • Communities of Concern

PEDESTRIAN COMPOSITE INDEX

Transit stops were placed into three categories:

  • Area Within ¼ Mile of a High-Volume

Stop – 1 pt

  • Area Within ½ Mile of a High-Volume

Stop – 0.5 pts

  • Area Within ¼ Mile of a Low-Volume or

No-Data Stop – 0.25 pts

* High-Volume stops are those that average at least 10 transit boarding's per day. 6

PEDESTRIAN COMPOSITE INDEX

Parks and libraries each had one category:

  • Area Within ¼ Mile of a Park – 1 pt
  • Area Within ¼ Mile of a Public Library - 1 pt

PEDESTRIAN COMPOSITE INDEX

Middle schools, high schools, and college & university had two categories:

  • Area Within ¼ Mile – 1 pt
  • Area Within 1 Mile – 0.5 pts

SCHOOLS AND COLLEGES & UNIVERSITIES

Elementary schools had two categories:

  • Area Within ¼ Mile – 1 pt
  • Area Within ½ Mile – 0.5 pts

DATA EXAMPLE

PEDESTRIAN COMPOSITE INDEX

Walkable businesses included categories such as restaurants, retail, convenience, fun, grocery, food, pharmacy, liquor, and personal care that were within a quarter mile of a sidewalk.

WALKABLE BUSINESSES

Categories included:

  • High Density of Walkable Businesses

in a TAZ- 1 pt

  • Medium Density of Walkable Businesses

in a TAZ – 0.75 pts

  • Low Density of Walkable Businesses

in a TAZ – 0.5 pts

DATA EXAMPLE

PEDESTRIAN COMPOSITE INDEX

For this study, we included areas with high populations of youth, elderly, those with Limited English Proficiency, individuals with disabilities, low-income households, and households without a vehicle.

10

COMMUNITIES OF CONCERN

Categories included:

  • High Density in Block Group – 1 pt
  • Medium/High Density in Block Group – 0.75 pts
  • Medium/Low Density in Block Group – 0.5 pts
  • Low Density in Block Group – 0.25 pts

DATA EXAMPLE

PEDESTRIAN COMPOSITE INDEX

PEDESTRIAN DETERRENT - DATA USED

  • Pedestrian and Bicycle Involved Crashes
  • Traffic Volumes
  • Physical Barriers to Active Transportation
  • Number of Lanes on the Roadway
  • Lack of Sidewalk

PEDESTRIAN COMPOSITE INDEX

To determine the crash score, recorded crash locations from 2013-2017 were added as points on the map. The density of points per TAZ was calculated by number of crashes per square mile.

13

PEDESTRIAN & BICYCLE CRASHES

Categories included:

  • High Density of Crashes in a TAZ- 1 pt
  • Medium/High Density of Crashes in

a TAZ – 0.75 pts

  • Medium/Low Density of Crashes in

a TAZ – 0.5 pts

  • Low Density of Crashes in TAZ – 0.25 pts

DATA EXAMPLE

PEDESTRIAN COMPOSITE INDEX

To determine the sidewalk coverage, the total length of sidewalk that was within a 60ft buffer of each road segment was calculated and compared to the total length of the corresponding road.

14

LACK OF SIDEWALK

Categories included:

  • Roadways with Little or No Sidewalk

Coverage – 1 pt

  • Roadways with Partial Sidewalk

Coverage – 0.5 pts

  • Roadways with Full Sidewalk

Coverage – 0 pts

DATA EXAMPLE

PEDESTRIAN COMPOSITE INDEX

The Barrier score was determined using natural and man-made barriers in the region. This includes rivers, major roadways and highways, and railroad tracks.

15

PHYSICAL BARRIERS

Determination of score:

  • Road Segments that Intersect with

Barrier – 1 pt

  • Road Segments that do not Intersect

with Barrier – 0 pts

DATA EXAMPLE

slide-16
SLIDE 16

PEDESTRIAN COMPOSITE INDEX

Road segments were placed into three categories based on their number of

  • lanes. Categories included:
  • Road Segments with

5 or More Lanes – 1 pt

  • Road Segments with

3 or 4 Lanes – 0.5 pts

  • Road Segments with

1 or 2 Lanes – 0 pts

16

NUMBER OF LANES AND TRAFFIC VOLUME

Traffic volume was based on Annual Average Daily Traffic Counts (AADT). Categories included:

  • Roads with AADT Greater than

15,000 – 1 pt

  • Roads with AADT Between 5,000

and 14,999 – 0.5 pts

  • Roads with AADT Less than 4,999
  • r No Data – 0 pts
