Reports

Highway Assignment Report

The highway validation report in HTML format is generated in the following directory: \Scenarios\{SCENARIO_NAME}\Output\HTML.

Transit Assignment Report

Boardings and alightings by route as well as station-level summaries are stored in their respective databases. The user can simply load the List layout files (.llax) in the /listings sub-directory to generate boarding summaries.

DaySim Reports

An established R process is used to automatically execute the summary R scripts and populate the DaySim summary spreadsheets. This process is called from within Visum procedure sequence and executed at the end of the model system run. All these files can all be found in “\Scenarios\{SCENARIO_NAME}\Output\DaySim\Reporting\R_Summary” folder of the scenario directory. The summary script is called “main.R” and can be found in \tools\DaySim_Summaries\. The Daysim reports include spreadsheets summarizing the following:

Usual work location
Usual school location
Vehicle availability
Day Pattern
Escort tour destination
Personal business tour destination
Shop tour destination
Meal tour destination
Social / recreational tour destination
Work-based tour destination
Tour mode
Tour time-of-day
Trip destination
Trip mode
Trip time-of-day

The DaySim summaries are also output in “\Scenarios\{SCENARIO_NAME}\Output\DaySim\Reporting\R_Summary” folder of the scenario directory. All the summaries are *.xlsm spreadsheets that are macro-enabled which updates the calculations and graphs in them automatically each time they are opened. The summaries range from work place distance distribution to tour/trip generation rates to modal shares.

Prior to the running of R summary script, all the spreadsheet templates are copied over to “\Scenarios\{SCENARIO_NAME}\Output\DaySim\Reporting\R_Summary” in the scenario directory from “\tools\DaySim_Summaries\output” in the model directory. These help in the validation of DaySim outputs. The summary R script uses files from NHTS that have been processed in the same format as DaySim output files. The processed NHTS files for Florida that include the add-on survey can be found in “tools\DaySim_Summaries\NHTS”.

All the steps have been fully automated using Visum's Python API.

-The user should also ensure that “R_PATH” key in the catalog is set correctly before running the model. For example, if R 2.15.2 is installed on the system R_PATH should be set to “C:\Program Files\R\R-2.15.2\bin\x64\R.exe”. It is recommended that the 64-bit version of R executable be used since it can then use all the memory available on the system. Otherwise, R is restricted to using a maximum of 4 GB of RAM. The R script run produces a log file called “DSValidationLog.txt” in the same directory that could be looked at to detect any errors encountered during the run.
