PEOPLE on the STREETS Kelly McGillivray Peoplecount
We set out to find… HOW MANY people WALK on streets?
We wanted to estimate… 24-hour mid-block count 2 sides of the street 2 directions of travel
Across an ENTIRE city!
Im going to tell you… HOW we did it WHAT we created WHY its useful
HOW we did it
We did field work… 7 cities 560 pedestrian counts 60 km of sidewalk
3 COUNT SOURCES: Stationary cameras Mobile camera Manual counts
Stationary cameras – 18 hour counts
Mobile camera – 12 hour counts
Manual counts – 5 min./block/hour
Chicago Pedestrian Counts
WHAT we created
CHALLENGES Economical Universal data sources Apply to ANY city
VARIABLES Tested Local Census Spatial
AADT Road Class Transit Stop One Way LOCAL Variables
CENSUS Variables Population density Employment density Mode Choice
We created a new variable… Pedestrian Density = Daytime Population X% Non-Drivers
Chicago Pedestrian Density
SPATIAL Variables Axial line length Average depth What are spatial variables?
AXIAL Mapping Draw lines of sight 1 km buffer Analyze with software 13 integration variables
Sample Axial Map
AVERAGE DEPTH # steps from one point in system to all other points. A F D B E C A B1 A E1 A D2 A F2 A C3 Avg Depth of A = 9/6 = 1.5
Manhattan Axial Map Showing Average Depth AAAAAAAAAAAAA
Manhattan Estimated Pedestrian Volumes
Pedestrian Model Accuracy
WHY its useful
USES FOR PED MODEL? PLANNING cheap counts ped LOS ped signals ped crossings accident rates COMMERCIAL location analysis retail real estate outdoor ads BIAs
LIMITATIONS Granularity – 1 to 5 blocks Anomalies – tourist areas Seasonality – not adjusted
Pedestrian Paths Modelled Now
Neighbourhood Level Detail
Get to know YOUR PEOPLE on the STREET
