SCENARIO
Multi-Issue Scenario File Manager and Plugin
SCENARIO is the function in TEAPAC Complete
for creating and managing
multi-variable, multi-issue scenario analyses for any other TEAPAC application, as well as
for any third-party program for which TEAPAC can create data files. The
key to the value of SCENARIO is that all of the data files for the
multi-variable analyses are maintained without any duplication of data, this
duplication being the typical downfall for the more common use of the SaveAs
function to save multiple data files for multiple scenarios. When SaveAs
is used, most of the data in each of the files is a duplicate of every other
file, causing undue burdens on the user to make subsequent changes in every file
when input data values are changed due to identified errors or changing
assumptions. With SCENARIO, a single data file is maintained for the data
which doesn’t change between analyses, while separate data files are created and
maintained automatically for the values which change between scenarios. In any TEAPAC
application using the defined scenario structure, the appropriate
files are used automatically to save and retrieve data from the designated
scenario cases, making the management of the entire data effort simple and easy,
regardless of the complexity of the analysis or the number of conditions being
analyzed.
Scenario definitions can be conceptually simple with something as mundane as
three volume conditions for a single intersection, or almost arbitrarily complex
with multiple independent issues (up to five), each of which vary arbitrary,
user-defined sets of mutually-exclusive data variables, with as many as 25
conditions for each defined issue. Any time a change is made to a given
scenario, either in input values or results to be passed to another function, the
change is saved in the proper condition files for easy retrieval by the next
function and/or at a later date by the same function.
SCENARIO has the ability to manage data for any TEAPAC application function, including
signal analysis, traffic impact analysis, count analysis and progression
analysis. Since it also directly
manages exported data, it
thereby allows for the indirect management of data files for HCS, NOSTOP,
TRANSYT, TSPPD, PASSER-II, SYNCHRO, NETSIM/CORSIM, to take advantage
of the benefits each of these programs offer.
