New Additions and Features

McTrans' latest software development, HCST7F is being
tested now. In addition to the integration with TRANSYT-7F
(featured in the last newsletter), this version will include the
new Interchanges module implementing the recently approved
Highway Capacity Manual (HCM) Chapter 26 procedures for
Interchange Ramp Terminals.

The new methodology covers the analysis of eight interchange
types, including, Single-Point Urban Interchange (SPUI);
Diamond Interchange (CUDI, CDI, TUDI); Partial CloverleafA
- 4 Quadrants (Parclo A 4Q); Partial CloverleafA 2 Quadrants
(Parclo A 2Q); Partial Cloverleaf B 4 Quadrants (Parclo B
4Q); Partial Cloverleaf B 2 Quadrants (Parclo B 2Q); Partial
CloverleafAB 2 Quadrants (Parclo AB 2Q); and Partial
CloverleafAB 4 Quadrants (Parclo AB 4Q).

The analysis is based on the procedures for signalized intersections,
but adds several components to account for the unique relationship
between signals controlling the ramps at interchanges.

Turn Radius: Adjusts saturation flow rate for the effects of
turning movement geometry on vehicle headway.
Lane Utilization: Adjusts the saturation flow rate for uneven
lane distribution due to downstream turn proportions.
Downstream Queue: Provides for additional lost time caused
by the blocking of upstream movements by the queue.
Demand Starvation: Provides for additional lost time created
when signal timing inhibits the downstream demand.
Traffic Pressure: Adjusts the saturation flow rate for the
reduction in headway created with higher demand flows.

The measures of effectiveness are computed for the various
origin-destination (O-D) pairs to completely describe operations
through both intersections. Level of Service (LOS) is provided
for each O-D and is based on control delay in seconds per
vehicle (like in Signalized Intersections), but with modified
LOS thresholds to account for the vehicle traveling through two
intersections. There are also two additional provisions for LOS F.
If either the volume-to-capacity ratio or the queue storage ratio
exceeds 1.0, the LOS is F.

HCS+ registered users will receive the new HCST7F product
automatically when released. TRANSYT-7F and HCS2000

Visual TEAPAC Gets Addition of SCENARIO

Visual TEAPAC is now available with
SCENARIO, a powerful program to create
and manage the multi-scenario analyses
often conducted with any of the 13 other
TEAPAC programs.


SCENARIO is a new Visual TEAPAC
program that can create multi-scenario data
files either from scratch or from data files of
earlier versions of TEAPAC. Users can:

select from pre-defined typical scenario
customize a pre-defined scenario
structure, or
create completely unique scenario

SCENARIO also functions as a plugin for
all other Visual TEAPAC programs so that
every program automatically understands
the SCENARIO file structure. The primary
advantage of using SCENARIO is that all
the scenario data is saved without dangers
of duplicated data which often occur when
scenarios are managed by the typical use of

SCENARIO can easily define single-issue or
multi-issue conditions, and any data dialog
can be assigned or re-assigned to any Issue
for as many as five independent, mutually-
exclusive Issues. For example, a simple
single-issue scenario is multiple volume
conditions for one or more intersections for
which capacity analysis, intersection design
and/or signal timing optimization would
be needed with SIGNAL2000. Initially, the
VOLUME dialog could be assigned to the
Issue named "Volume Conditions" and up to
25 different Conditions could be named and
saved with unique volumes.

Later, additional data like
could be added to the defined Issue for each
condition, and/or additional Conditions
could be added. Other examples of a single-
issue analysis are multiple years of traffic
count data for TURNS or WARRANTS, or
multiple years or zones of land use for SITE's
projected traffic estimation.

Multi-issue scenarios could be combinations
of any of these, where the variation of one
variable is independent of the others, such
as changing volumes based on the time-of-
day and/or day-of-week while independently
changing intersection geometrics depending
on differing funding possibilities.

Why Is SCENARIO So Important?

Multi-scenario analyses are endemic to
traffic engineering analyses. Everyone
does these types of analyses all the time.
So why is SCENARIO such a significant
breakthrough? The answer lies in the
way that most multi-scenario analyses
are currently conducted versus how it
is handled with SCENARIO, and the
ramifications these differences have on the

The most common way to create a multi-
scenario analysis with ANY program is to
open the data file from the first analysis,
change the data that defines the second
scenario, and use the File-SaveAs menu to
save the conditions under a different file
name. This is easily done for any number of
conditions which are analyzed, and is often
extended as the project proceeds to consider
scenarios not originally anticipated.

The problem with this approach is that
typically 90% or more of the data saved in
each file is exactly the same, and if any of
that data changes during the course of the
analysis, it must be changed in every file.
This is a time-consuming and tedious effort
that is frequently omitted due to lack of
time, budget or motivation. This is where
the SaveAs approach breaks down and is
often the root cause of numerous problems
later on in the project, sometimes even in a
debilitating way.

Enter SCENARIO: for data which does
not change from case to case, SCENARIO
only saves one copy of that data, so if it
changes, the change is saved immediately
and only once. It is changed quickly,
easily and without hesitation, keeping the
entire database for all the project analyses
internally consistent for any subsequent

Exploit The Power of SCENARIO for Third-
Party Software

While SCENARIO is easily seen as
indispensable for most any Visual TEAPAC
analysis, due to the connection of TEAPAC
to many other 3rd-party programs, use of
these other programs can also gain a huge
advantage from the multi-scenario data
management offered by SCENARIO.

For example, while in TRANSYT or
CORSIM, SaveAs is typically used to create
multiple data files with different analysis
volumes and thus huge amounts of duplicate
data for all other data entries. Creating
duplicate-free data for PRETRANSYT or
PRENETSIM is trivial with SCENARIO,
and because of the seamless sharing of
data files among all Visual TEAPAC
programs, the same data is easily used by
SIGNAL2000 for HCM-compliant capacity
analyses and timing/phasing optimizations,
as well as to compute saturation flow rates
needed by TRANSYT and CORSIM.
Other 3rd-party programs like Synchro, TS/
PP-Draft and PASSER-II are easily added to
the multi-scenario analysis by the immediate
seamless compatibility of PRESYNCHRO,
