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

Economic Procedure
THREE INPUT LOOKUP
TABLES
Key Output File
1.
Linked to Economic Growth for
a Scenario
1.
Link File with Costs appended
for each Link
2.
Vehicle Operating Costs by
Link Class
2.
Economic Summary File,
Economic Cost of Project
3.
Accident Costs
Pilot Program
1.
Creates a File name and
directory for economic costs for a
particular scenario eg

Creation of Economic Curves
Prepared for 11 Vehicle Classes
 HDM4 Relationships incorporated from
REDS (Roads Economic Decision
Model)
 Vehicle Operating Cost calculated for a
specified range of speeds for pre
determined road conditions such as
roughness, gradient and curvature


An Interlude ---The HDM-4
Model, a tool of the World Bank

Analytical tool for engineering and
economic assessment of
- road investments and maintenance
- transport pricing and regulation

Physical and economic relationships derived
from extensive research on road deterioration,
the effects of maintenance activities, and
vehicle operation and user costs

CURRENT STATUS
Economic Cost estimated for each scenario
 With and without Cases from CUBE
Voyager written to CSV Files
 Economic evaluation Spread sheet still not
in Voyager but linked directly to Voyager
output files
 Simply Open Economic Spreadsheet and
Update Links to Produce EIRR for any
scenario
