##  4.1 Installing STEAM Software

The STEAM software has an installation program that installs the proper
files on a user's hard drive in order to run the program. The install
package is a regular Windows Install-Shield program that is used in the
majority of Windows software and is familiar to most Windows users.
Close all other programs before beginning the installation process in
order to avoid any conflicts with shared files. STEAM Release Version
1.0 will only run under Windows 95 or NT operating systems.

To run the install program, the user executes the "Setup" command from
Windows which loads the setup program and prompts the user for specific
information. Initially, the setup program prompts the user to select a
directory for the STEAM program with a default directory "C:/STEAM".
Exhibit 4.1 shows the screen displayed for the STEAM setup. By selecting
the setup button the install package copies the necessary program files
into the proper directory and the necessary windows files into the
windows directory.

height="3.3493055555555555in"}

To run the STEAM program, run the "STEAM.exe" file from the windows
program.

##  4.2 STEAM Program Screen

Exhibit 4.2 presents the STEAM program screen which the software user
works with in order to run a benefit-cost analysis. The main screen is
divided into two large windows: an outline window (on the left) and a
display window (on the right). The software user will make a selection
from the outline window by clicking or double clicking a specific item
which will activate the display window to present information for that
selection. The outline window is changed by making a selection from the
"Edit Menu".

The program screen has five menu categories: File, Edit, Run, Results,
and Help. Exhibit 4.3 shows the full structure of the menu options under
the categories. A brief description of each of the options is provided
below.

> *File/New* -- Creates a new scenario to run the STEAM analysis and
> sets the input parameters to the default values.

##  4.3 Creating, Loading, and Saving Scenarios

The STEAM software uses the term "scenarios" to define the benefit cost
analysis of a given set of transportation system improvements. Users may
decide to change specific assumptions and therefore would want to create
a different scenario to perform a second analysis. The STEAM software
allows users to create multiple scenarios that can be saved, loaded, and
run at later times without going through the entire process of defining
market sectors and adjusting input parameters.

The assumptions, output, and input file locations for each scenario are
stored in a scenario file. Under the "File" menu, the "New", "Load",
"Save", and "Save As" options allow the user to create, load, save, and
save the scenario under a different file name. These options work the
same as similar options in other Windows programs. Standard Windows file
dialog boxes allow the user to locate files in specific directories.
Exhibit 4.4 shows the file dialog box that is displayed when one of the
options is selected.

The default scenario file extension is ".scn". However, the file can be
saved using any extension that the user chooses.

> **Exhibit 4.4 STEAM File Dialog Box**

##  4.4 Defining Market Sectors

The STEAM program analyzes investment decisions by examining individual
market sectors that represent portions of the transportation demand on
the network. Market sectors can represent travel demand by mode, trip
purpose, and time of day, depending on the trip table purpose
categories, modes, and time period breakdowns output by the travel
demand model. Thus, a demand model which produces trip tables for 3 trip
purposes, 3 modes and 3 time periods could potentially result in a
maximum of 27 market sectors, unless some of these potential market
sectors are combined with one another.

Initially, a new market sector is defined by selecting the "Market
Sector" option under the "Edit" menu. A market sector dialog box is
displayed which list the existing market sectors in the current
scenario. The dialog box allows the user to add a new market sector,
delete an existing market sector, modify an existing market sector, or
cancel without any action. The market sector dialog box is shown in
Exhibit 4.5.

> **Exhibit 4.5 Market Sector Dialog Box**

![](media/image5.png){width="4.532638888888889in"
height="3.3993055555555554in"}

Once a market sector is added to the scenario, users select one of the
three tree options in the outline window: "Market Sector Information",
"Network and Trip Table Files", or "Market Sector Other Changes Files"
which will display, respectively, the market sector input screens
displayed in Exhibit 4.6, 4.7, and 4.8. These screens are used to input
market sector information necessary to perform the investment analysis.

> **Exhibit 4.6 Market Sector Information**

![](media/image6.png){width="4.532638888888889in"
height="3.3993055555555554in"}

> **Exhibit 4.7 Market Sector File Locations**

> Files**![](media/image8.png){width="4.532638888888889in"
> height="3.3993055555555554in"}

The "Market Sector Information" screen allows the user to name the
market sector, specify vehicle occupancy and daily-to-annual expansion
factor, and select mode of transportation and speed relationship. Each
input variable is defined below:

> *Market Sector Name.* The market sector name is used simply to keep
> track of individual market sectors and can have up to 28 characters.
>
> *Vehicle Occupancy.* The vehicle occupancy is the average number of
> people per vehicle and is used to estimate the number of vehicle trips
> for a given market sector based on the market sector person trip
> tables. Separate occupancies can be provided for the Base Case and the
> Improvement Case.
>
> *Expansion Factor.* The expansion factor is used to expand the trip
> tables to an annual value. A market sector that represents daily work
> trips may have an expansion factor of 250 to represent all work days
> for a given year.
>
> *Mode of Transportation.* This input option allows the user to select
> one of eight mode choices that include: auto, truck, carpool, local
> bus, express bus, light rail, heavy rail, and other. Modes that are
> not currently defined such as bicycle or walking can be put in the
> "other" categetory.
>
> *Speed Relationship.* Allows the user to select from four speed
> estimation methods. Three use relationships as a function of AWDT/C
> (average weekday daily traffic/capacity). They are the choices Daily,
> Peak, and Off-peak. The fourth method uses the speeds provided by the
> user in the network files.

The "Network and Trip Table Files" screen allows the user to identify
the input file locations for the current market sector, determine
whether or not to run the network analysis, and whether or not to use
travel time estimations for that market sector. Three check boxes are
located at the top of the screen which allow the user to run base or
improvement network analysis (if these boxes are not selected the user
cannot input file names for the network input files). The "Ignore
Network Travel Time Analysis" check box specifies that the market sector
will not use any travel time estimation for calculating benefits. This
option is generally used for transit market sectors for which the user
must provide estimated zone-to-zone travel times in the "Other Changes
File" screen. (If this option is selected, the network input and output
files become inactive).

An explanation of each of the files and options is provided below:

> *Run Network/Don't Run Network Option.* This option allows the user to
> select whether or not to run the highway network analysis. Once a
> network analysis has been performed on a particular network, there is
> no need to re-run the network analysis unless changes to the network
> have been made. The STEAM analysis will run significantly faster if
> the network analysis is not run.
>
> *Network Input File.* This input box provides the location of the
> network file. The format of the file is described in the "Input File"
> section of this report.
>
> *Output File.* This input box provides the location of the network
> output file which is used later in the Trip Table analysis for
> estimating travel time benefits. This file is an intermediate binary
> file that is only used by the STEAM program.
>
> *Trip Table File.* This input box provides the location of the trip
> table file. The trip tables are used in estimating benefits and costs
> occurring on a particular network. The format of the trip table file
> is described in the "Input File" section of this report.
>
> *Centroid File.* This input box provides the location of the centroid
> file which contains information on the zones specified for the travel
> time analysis. Each zone is identified with the corresponding node
> location. Only one centroid file is necessary and is used in both the
> base and improvement cases. All market sectors require this file.
>
> *Market Sector Output File.* This input box provides the location of
> the market sector output file which contains a summary of the output
> of the market sector which is combined with other market sectors to
> produce a summary analysis. Each market sector requires a unique
> market sector output file name.

##  4.5 Changing Parameter Values

The STEAM benefit-cost analysis uses a number of different parameters
such as value of time, emission rates, and accident costs to perform the
investment analysis. The program has default values for these input
parameters; however, software users should change the input values to
reflect the specific year of analysis and the specific location or
situation. Appendix D discusses methodology that can be used to update
emission factors. All default values in STEAM are based on typical U.S.
metropolitan values; they are provided for use in testing the software
only, and should not be used for a specific analysis without a thorough
review of reasonableness. Sources of these values are described in
Appendix C. All parameter values can be changed by the user, and are
saved in the scenario input file. However, the default values included
with the software cannot be changed by the STEAM user. Therefore, to
avoid having to change parameters for each scenario, it is recommended
that the user develop an initial "generic"scenario file with local
parameters, and use this file as a base to be modified for each new
scenario.

To change input parameter values, the user must first select the "Model
Parameters" option from the "Edit" menu. This changes the information in
the outline window and displays a list of parameter names as shown in
Exhibit 4.9. The user needs to click or double click a particular item
from the outline window to show the parameter information in the display
window. In Exhibit 4.9, the "In-Vehicle Value of Time" parameter has
been selected, displaying the values by mode. The user can change these
values by overwriting the existing value. New values are saved when the
scenario file is saved.

> **Exhibit 4.9 Model Parameters ( In-Vehicle Value of Time)**

![](media/image9.png){width="4.532638888888889in"
height="3.3993055555555554in"}

A restore default button is provided in the top right corner of the
display window which will restore the parameters on the current screen
to their default values. A list of the model parameters is provided
below and full descriptions of each parameter are provided in Appendix
B: Glossary of Terms.

### Model Parameters

-   Value of Time

-   In-Vehicle (auto, truck, carpool, local bus, express bus, light
    rail, heavy rail, and other)

-   Out-of-Vehicle (auto, truck, carpool, local bus, express bus, light
    rail, heavy rail, and other)

-   Discount Rate

-   Cost Per Gallon of Fuel (auto, truck)

-   Fuel Consumption Rates

-   Auto and Truck Fuel Consumption Rates (13 MPH categories)

-   Transit Fuel Consumption Rates (local bus, express bus, light rail,
    heavy rail)

-   Non-Fuel Highway User Costs Per Vehicle Mile (auto, truck)

-   Emission Costs Per Ton (HC, CO, NOx, PM10)

-   HC Emission Rates Per Vehicle Mile

-   Auto and Truck HC Emission Rates (13 MPH categories)

-   Transit HC Emission Rates (bus, rail)

-   CO Emission Rates Per Vehicle Mile

-   Auto and Truck CO Emission Rates (13 MPH categories)

-   NOx Emission Rates Per Vehicle Mile

-   Auto and Truck Nox Emission Rates (13 MPH categories)

-   Transit Nox Emission Rates (bus, rail)

-   PM10 Emission Rates Per Vehicle Mile

-   Auto and Truck PM10 Rates (13 MPH categories)

-   Transit PM10 Rates (bus, rail)

-   Cost Per Accident (internal and external fatality, injury, and
    property-damage-only)

-   Emissions Per Cold Start (auto and truck HC, CO, NOx, PM10)

-   Cold Start Per Vehicle Trip (auto, truck)

-   Fatal Accident Rates (auto and truck by highway class, bus, rail)

-   Noise Damage Costs (auto and truck by highway class, bus, rail)

-   Other Mileage Based External Costs (auto and truck by highway class,
    bus, rail)

-   Non-Mileage Based External Costs

-   Transit Agency Unit Costs (\$/vehicle mile, \$/vehicle hour, \$/peak
    vehicle). Note that bus fuel costs must be included in these costs,
    because STEAM does not calculate fuel consumption *costs* separately
    on the basis of bus VMT, although it does so for fuel consumption
    itself (in gallons) and for energy equivalents and carbon dioxide
    emissions.

Examples of non-mileage based external costs include noise, travel
delay, and fugitive dust during construction. Also, the STEAM user can
use the parameters for other mileage-based external costs to account
other external costs.

##  4.6 Specifying Improvement Costs

Capital cost values are necessary in calculating a benefit-cost ratio
for the proposed improvements. The software user enters the capital
costs, the midpoint of construction, year of opening, useful life, and
salvage value for all improvements being analyzed. STEAM allows each
scenario up to 5 different capital investments.

To enter improvement cost information, the software user must select the
"Improvement Cost" option from the "Edit" menu. The user then selects
"Capital Cost Items" from the outline window. Exhibit 4.10 shows the
Improvement Cost screen which is used to enter the capital cost
information.

> **Exhibit 4.10 Improvement Cost Screen**

![](media/image10.png){width="4.532638888888889in"
height="3.3993055555555554in"}

The following information is entered for up to 5 items:

> *Capital Costs.* This is the full cost of the capital improvement,
> which includes any engineering studies, right-of-way acquisition and
> all construction expenditures. Alternatively, engineering and
> right-of-way costs can be treated as separate capital cost items. For
> multiyear projects, capital costs include all expenditures made from
> start to completion. This variable is in dollars.
>
> *Midpoint of Construction.* This is the year that falls in the mid
> point of the construction period. For single year construction
> projects the midpoint of construction would be the same as the year of
> opening.
>
> *Year of Opening.* This is the year that the improvement project is
> planned to be completed and opened for use.
>
> *Useful Life.* Useful life is the estimated number of years that a
> project can be used without requiring major reconstruction of the
> facility.
>
> *Salvage Value.* This is the remaining value of the investment at the
> end of its useful life.
>
> *External Cost of Construction.* The external costs to transportation
> users or non-users that occur as a result of the construction process.

If no capital cost items are specified in the scenario, a benefit
analysis is performed that estimates the benefit or costs to highway and
transit users.

Other changes in operating and maintenance costs are specified in the
second capital cost item screen displayed in Exhibit 4.11. These costs
would represent the annual cost of operating and maintaining a new
highway if the improvement was to construct a new highway. Also, it
could include any transit or other modal costs (e.g., bikeways or travel
demand management operations) not covered elsewhere.

> **Exhibit 4.11 Other Operating and Maintenance Cost Screen**
>
> ![](media/image11.png){width="4.532638888888889in"
> height="3.3993055555555554in"}

##  4.7 Transit Service Changes

For the transit modes (local bus, express bus, light rail and heavy
rail), the STEAM benefit-cost analysis allows the user to input transit
service changes estimated by the user in order to calculate changes in
transit costs, and other impacts such as fuel consumption and carbon
dioxide and pollutant emissions changes. There are three types of
transit service changes that can be specified: Transit VMT, Transit
Vehicle Hours, and Transit Peak Vehicles. Exhibit 4.12 shows one of the
three screens to enter the transit service changes.

To display the transit service changes screens, the user needs to select
the "Transit Service Changes" option from the "Edit" menu and then
select either "Transit Vehicle Miles", "Transit Vehicle Hours", or "Peak
Vehicles" from the outline window.

The user may input only the vehicle mile changes, or both vehicle mile
and vehicle hour changes, or all three transit service changes (vehicle
miles, vehicle hours, and peak vehicles). While more than one type of
change can be specified by the user, the user-provided unit costs
associated with the changes must be additive because all three costs
will be included in the analysis. Note that vehicle mile changes are
also used to estimate fuel consumption, energy, carbon dioxide, and
pollutant emissions changes.

> **Exhibit 4.12 Transit Service Changes**

![](media/image12.png){width="4.532638888888889in"
height="3.3993055555555554in"}

Transit service changes are entered in miles, hours, and vehicles. A
description of the three service changes is provided below:

> *Transit Vehicle Miles.* The total annual change in transit vehicle
> miles that occurs as a result of the highway or transit improvement.
>
> *Transit Vehicle Hours.* The total annual change in transit vehicle
> hours that occurs as a result of the highway or transit improvement.
>
> *Peak Vehicles.* The average change in transit peak vehicles that
> occurs as a result of the highway or transit improvement.

##  4.8 Defining Risk Analysis Input Ranges

To run the risk analysis procedure on the investment scenario, the user
must define ranges for input variables. The input value ranges determine
the high (95 percentile) and low (5 percentile) points for the input
variable and the shape of the distribution curve between the high and
low points. A log normal distribution is used to determine the shape of
the curve for all input variables.

In order to set the risk analysis input ranges, the user must select
"Ranges for Risk Analysis" option under the "Edit" menu. This will
display a list of input variables that risk ranges can be specified in
the outline window. By selecting one of the input variables the risk
input screen is created in the display window.

Exhibit 4.13 shows the Input Variable Risk Analysis screen. The user can
enter the high value for the input variable. Most of the input variables
use a risk factor which is a factor applied to all of the input
variables in that category. An example is the HC emission rates. A
factor of 2.5 means that the high value for all HC emission rates is 2.5
times the average values specified in the Model Parameter screens. This
is applied to all 13 HC emission rates by speed increment. The low value
is calculated by the program based on the log normal distribution and
the high and mid points.

> **Exhibit 4.13 Defining Risk Analysis Ranges**

To graph the curve of the distribution of the input values, the user
must select the "Graph" button. Similar to other input screens, a
"Restore Defaults" button is provided that resets the input variable
risk range to the default values. In addition, at the bottom of the
screen are "Histogram" and "Cumulative" buttons which change the graph
from a histogram to a cumulative distribution curve. The cumulative
distribution curve is shown in Exhibit 4.14.

> **Exhibit 4.14 Cumulative Distribution Curve for Risk**

> **Analysis Ranges**

![](media/image14.png){width="4.532638888888889in"
height="3.3993055555555554in"}

Finally, the number of iterations the risk analysis procedure runs must
be specified. The "Number of Iterations" is the number of times that the
analysis cycles through the benefit cost estimation using different
input values determined by the probability curves and a monte carlo
simulation.

To set the number of iterations for risk analysis, the user must select
"Number of Iterations" in the outline window. Exhibit 4.15 shows the
screen for changing the iteration value. Risk analysis iterations can be
set from 100 - 2000 with the default value at 2000.

> **Exhibit 4.15 Number of Iterations for Risk Analysis**

height="3.3993055555555554in"}

##  4.9 Checking Input Data Files

The STEAM software has a data checking routine that allows the user to
check the formats and valid ranges of the data input files specified in
the current scenario. This provides important information in identifying
where a problem may exist and which file may not be specified correctly.

In order to run the data checking utility, the software user must first
create or load the scenario (.scn) file with the all the market sectors
and input files specified. Once the scenario file is completed, the user
can run the data checking utility by selecting the "Check Data Input
Files" sub-option under "Check Data Input Files" option of the "Run"
menu. The data checking utility may take a minute or two depending on
the number of market sectors specified.

Once the data checking utility has been run, the result log can be
viewed by selecting the "View Data Check Log (for most recent data
check)" sub-option under the "Check Data Input Files" option in the
"Run" menu. The log is for the most recent run of the data check which
will be overwritten when another data check is performed. The Data Check
Log view screen is presented in Exhibit 4.16.

Exhibit 4.17 shows a sample data check log for a scenario that was
specified correctly and for which all the input files are in the proper
format. The log is for a 6 market sector example. Exhibit 4.18 presents
a sample data check log showing the error messages that occur when files
cannot be found, if the input file is not in a correct format, or if the
number of zones in an input file does not match the number of zones
specified in the scenario.

##  4.10 Estimating Run Time

To estimate run time, a scenario must first be defined [and
saved]{.underline} with all the markets sectors included. Once this has
been done, select "Estimate Run Time" from the "Edit" menu. Chose either
"Estimate Run Time Without Risk Analysis" or "Estimate Run Time With
Risk Analysis" depending on which analysis is desired. STEAM calculates
run time based on the number of market sectors, the number of centroids,
and the speed of the computer that is running the model. Exhibit 4.19
shows the message box reporting the run time estimation.

**Exhibit 4.19 Estimating Run Time**

![](media/image17.png){width="4.532638888888889in"
height="3.3993055555555554in"}

Network travel time estimations are the most time consuming process in
the benefit-cost analysis. If the user is re-running a scenario that
does not change previous travel time estimations or if the user has
market sectors that use the same networks, there is no need to repeat
the network travel time estimation procedure. Skipping travel time
estimation will significantly reduce the model run time.

##  4.11 Performing Investment Analysis

To perform an investment analysis, the user must first define the
scenario with all the market sectors included and adjust any parameter
values that may apply to the run. The scenario file needs to be named
prior to running the analysis.

Once the scenario has been properly defined, the user begins the
analysis by selecting the "Run Model" option under the "Run" menu item.
The user then selects the "Run Model Without Risk Analysis" sub-option,
or the "Run Model With Risk Analysis" option. Exhibit 4.20 shows the
progress screen displayed when the program is running.

> **Exhibit 4.20 Running STEAM Analysis**

![](media/image18.png){width="4.532638888888889in"
height="3.3993055555555554in"}

The analysis can be stopped by selecting the "Cancel" button on progress
screen. The gauge on the screen indicates the percentage completion of
the analysis and the remaining time value gives an estimate of the
remaining time until completion.

##  4.12 Viewing Results

Once the benefit-cost analysis has been performed, the software allows
the user to view the output results of the current scenario and the risk
analysis output ranges. The output information is saved to the scenario
file in an ASCII format that can be imported to most applications
including most spreadsheet programs. In addition to output results, the
file contains the input assumptions that were used to produce the
results.

To view the output file of the current scenario the user must select the
"Show Current Scenario Results" option from the "Results" menu item.
Exhibit 4.21 shows the screen that displays the output file for a given
scenario. Scroll bars allow the user to move vertically and horizontally
through the file. The viewer simply displays the contents of the output
file but does not allow the user to edit the file.

> **Exhibit 4.21 Viewing Results**

![](media/image19.png){width="4.532638888888889in"
height="3.3993055555555554in"}

To view the output for selected variables from the risk analysis, the
user must select the "Show Risk Analysis Results" option from the
"Results" menu. This action displays a list of output items in the
outline window. By selecting one of the output items in the outline
window, the range of results for that item is graphed in the display
window.

The top of the screen displays the mean and median values for the output
variable. The right side of the graph presents the probability values.
Similar to the input risk range screens, a "Histogram" and a
"Cumulative" button is provided to allow the user to switch between the
two types of graphs. Exhibit 4.22 shows the non-cumulative graph for the
benefit-cost ratio result and Exhibit 4.23 shows the same output in a
cumulative format.

Exhibit 4.24 presents the full layout of a scenario file.
