Transcript Slide 1

Overview
• Detailed description of
Cost Matrices
– Commuter
– Transportation
– Accessibility
• Steps to building a
simulation and
understanding your
results
Commuter Cost Matrix
• Captures changes to
time per trip for offthe-clock, work-related
trips.
• Calculated through
VHT/Trips
• Think—Would NYC still
be a financial center
without its subway
system?
Transportation Cost Matrix
• Captures the on-theclock business travel
and transport of goods.
• Calculated in two ways:
– Ratio of VMT to VHT
between alternate and
baseline scenarios
– Cost per trip of
commercial truck
deliveries
Accessibility Cost Matrix
• Calculates changes in
access to
intermediate inputs
and consumer goods
• Explains residual bias
toward local
suppliers
• Calculated through
Trips/VHT
Accessibility Cost Matrix
Baseline value
calculated with
REMI dynamic
estimation to
estimate distance
deterrence factors
which are
normalized to 1.
Capturing Mobility Benefits of
Long-Range Plans (1)
• Step 1-Importing
Travel Files
– “maintenance
only” base case
– “maintenance +
capacity
improvement”
alternate case

• Step 3- Understanding
the Results
– Analytical graphs
– Labor productivity?
– Sector sensitivity to
transportation?
– Industrial
composition?
– Cross-regional
benefits?
