1)
For a given country, compute unit vehicle operating
costs (VOC) and speeds function of roughness
using the RED - HDM-III VOC Workbook
or the RED - HDM-4 VOC Workbook or
any other model, and define cubic polynomials
relating unit VOCs and speeds to roughness,
which are essential to the use of the RED -
MAIN Workbook.
Use
the RED - HDM-III VOC Workbook to compute VOCs
and speeds for motorized vehicles, following
the HDM-III relationships, following the steps
below:
a)
Enter the country specific vehicle fleet data
on the Basic Input Data Worksheet.
b)
If necessary, enter the country specific calibration
data on the Calibration Data Worksheet.
c)
Compute the results by pressing the corresponding
button on the Compute Results Worksheet.
d)
Copy the results automatically into the RED
- MAIN Workbook by pressing the corresponding
button on the Compute Results Worksheet. Note
that RED - HDM-III VOC copies all the corresponding
results of the nine possible vehicle types
into RED - MAIN.

Enter the country specific vehicle fleet data
on the Basic Input Data Worksheet
.
b)
If necessary, enter the country specific calibration
data on the Calibration Data Worksheet.
c)
Compute the results by pressing the corresponding
button on the Compute Results Worksheet.
d)
Copy the results automatically into the RED
- MAIN Workbook by pressing the corresponding
button on the Compute Results Worksheet.
Note that RED - HDM-4 VOC copies all the corresponding
results of the nine possible vehicle types
into RED - MAIN.

Other
alternative is to use any other model to compute
VOCs and speeds as a function of roughness,
for motorized and non-motorized vehicles, and
to copy the corresponding cubic polynomial results
manually into the RED - MAIN workbook.
2)
