PEDESTRIAN COMPOSITE INDEX
STUDY BACKGROUND 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. • Pedestrian Generator − Measures areas that generate pedestrian activity • Pedestrian Deterrent − Measures areas that deter pedestrian activity 3
STUDY BACKGROUND 4
PEDESTRIAN COMPOSITE INDEX PEDESTRIAN GENERATOR - DATA USED • Transit Stops • High Schools • Public Parks • College and Universities • Public Libraries • Walkable Businesses • Elementary Schools • Communities of Concern • Middle Schools 5
PEDESTRIAN COMPOSITE INDEX TRANSIT STOPS 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 DATA EXAMPLE 10 transit boarding's per day. 6
PEDESTRIAN COMPOSITE INDEX PARKS AND LIBRARIES 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 DATA EXAMPLE 7
PEDESTRIAN COMPOSITE INDEX SCHOOLS AND COLLEGES & UNIVERSITIES Middle schools, high schools, and college & university had two categories : • Area Within ¼ Mile – 1 pt • Area Within 1 Mile – 0.5 pts Elementary schools had two categories : • Area Within ¼ Mile – 1 pt • Area Within ½ Mile – 0.5 pts DATA EXAMPLE 8
PEDESTRIAN COMPOSITE INDEX WALKABLE BUSINESSES 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. 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 DATA EXAMPLE in a TAZ – 0.5 pts 9
PEDESTRIAN COMPOSITE INDEX COMMUNITIES OF CONCERN 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. 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 DATA EXAMPLE • Low Density in Block Group – 0.25 pts 10
PEDESTRIAN COMPOSITE INDEX GENERATOR MAP Once all scores were joined to a single road network layer, the total score was added and then averaged. SECTION OF GENERATOR MAP 11
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 12
PEDESTRIAN COMPOSITE INDEX PEDESTRIAN & BICYCLE CRASHES 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 . 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 DATA EXAMPLE • Low Density of Crashes in TAZ – 0.25 pts 13
PEDESTRIAN COMPOSITE INDEX LACK OF SIDEWALK 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. Categories included: • Roadways with Little or No Sidewalk Coverage – 1 pt • Roadways with Partial Sidewalk Coverage – 0.5 pts • Roadways with Full Sidewalk DATA EXAMPLE Coverage – 0 pts 14
PEDESTRIAN COMPOSITE INDEX PHYSICAL BARRIERS The Barrier score was determined using natural and man-made barriers in the region. This includes rivers, major roadways and highways, and railroad tracks. Determination of score: • Road Segments that Intersect with Barrier – 1 pt • Road Segments that do not Intersect with Barrier – 0 pts DATA EXAMPLE 15
PEDESTRIAN COMPOSITE INDEX NUMBER OF LANES AND TRAFFIC VOLUME Road segments were placed into three Traffic volume was based on Annual categories based on their number of Average Daily Traffic Counts (AADT). lanes. Categories included: Categories included: • Road Segments with • Roads with AADT Greater than 5 or More Lanes – 1 pt 15,000 – 1 pt • Road Segments with • Roads with AADT Between 5,000 3 or 4 Lanes – 0.5 pts and 14,999 – 0.5 pts • Road Segments with • Roads with AADT Less than 4,999 1 or 2 Lanes – 0 pts or No Data – 0 pts 16
PEDESTRIAN COMPOSITE INDEX DETERRENT MAP Once all scores were joined to a single road network layer, the total score was added and then averaged. SECTION OF DETERRENT MAP 17
PEDESTRIAN COMPOSITE INDEX FINAL MAP To determine the final PCI, the generator scores and deterrent scores for each road section were combined and averaged together, ensuring they hold the same weight. SECTION OF FINAL MAP 18
