Purpose Develop mechanism to match
commuters to others with similar origin and destination

Method Data Collection Data Formatting Matching Output

Data Collection Ideally, data would be collected through
an internet application. Users would input their origin/destination
O-D data was not available, so we used a DAP File
Matched addresses from residential neighborhood (U-District) to addresses in commercial area (Downtown)

Data Formatting Origins from U-District into Origin
layer Destinations from Downtown into
Destination layer Unique ID called “LINK” matches
Origin to Destination Join Origins and Destinations Dissolve based on LINK to new O-D
layer

Data Formatting O-D layer – multipoint layer Each feature contains:
• two points – Origin and Destination• Complete address information for both

Matching Method:
• Build buffer around Origin and Destination (1000 feet)
• Select from O-D layer features with Origins and Destinations within buffers
• Create layer from selected features

Results Matches are output
to new Carpools feature class.
