Network Conversion
Step 1 - GIS Converter of STRADA~MIF
Shape for each mode-Strada Network
Step 2 - GIS Converter~Convert to
Arcview Network
Step 3 – Develop Database Program
to Modify some fields
Step 4 – Load Network Database
together with Shape File into
Voyager, and link with other GIS
data such as zone boundaries.
WE WILL SEE A DETAILED PICTURE OF THE FULL
NETWORK LATER

Model Parameters and Equations
Parameters for Trip Generation, Trip
Distribution and Modal Split were taken
from the earlier study report
documentation
 The modules were developed for both
person and freight trips
 Base Voyager Model was re-run to
ensure outcome of the same results

Why an Economic Module?

Often the Transport Model is removed from
economic analysis
 The Economic Analysis is a separate program
or spreadsheet analysis
 BUT WHAT IF?



Establish an Economic Framework
Each Model Run produces an economic cost or
financial cost or revenue
Previously we have done this using sometimes add
on programs
