RSAP Release Notes
Changes in Release 150507 include:
- A button has been added to the alternatives control box which will display graphically, the
alternative. This is useful for de bugging the models and making sure objects are located correctly on the road. The graph
is a strip chart meaning that horizontal and vertical curvature are not shown (i.e., everything is straight).
- A series of buttons has
been added to the analysis tab. To see the additional buttons, first select "see settings" and then check "Trajectory Debug".
The dialog box will now expand to include the trajectory debugger options. These options will display each trajectory as the
analysis is performed. This option is useful for debugging trajectories but should not be used to perform complete runs since
doing so would be extremely slow.
- The ADD nd percent trucks used in the analysis is now printed on the results page, at the top of
the feature report and the segment report.
- A bug was fixed which sometimes caused an error in the cross-section definitions when unequal
lanes (e.g., 1 primary and 2 opposing) are modeled.
- The cross-section page was modified such that when you click on a particular cell
(e.g., the segment and alternative) the cross-section graph shown to the right will correspond to the cell selected.
Release 140130 include:
- A risk analysis tool has been added which calculates the risk of observing a given severity over the
life of the project. The user can choose the severity of interest and the risk level for acceptance. Segments and alternatives
that meet the criteria are highlighted in green. The life-time risk is provided for each encroachment as well as for all encroachments
on the segment. A button was added to the Results page which directs the user to the Risk Report. To perform the risk
analysis the user must check the “Risk Analysis” box in the Analysis Settings.
- The former warrant tool was renamed the traffic
sensitivity tool. Segment risks were also added to the traffic sensitivity tool. To perform a traffic sensitivity analysis
the “Traffic Sensitivity Analysis” box on the Analysis Settings must be checked. There are further analysis setting shown to
indicate the number of iterations of AADT and percent truck and the increment to use.
- Two overlapping buttons were added to
the RSAP Controls Dialog while on the TRAFFIC INFORMATION page. One allows the user to enter the percent of trucks only and
RSAP automatically proportions the traffic mix. The other button allows the user to enter the traffic mix manually and then
RSAP calculates the percent trucks from that information.
- The default VSL has been updated to $9,100,000 as per http://www.dot.gov/office-policy/transportation-policy/guidance-treatment-economic-value-statistical-life
box was added on the Results section of the RSAP Controls Dialog that allows the user to either include or exclude terrain related
rollovers from the cost results.
- The severity database given on the Severity Worksheet was updated with several new default
- A bug was fixed which sometimes resulted in the program warning the user that the traffic mix did not add up to 100 percent
when in fact it did.
Changes in Release 130304 include:
- An error message was added when RSAP detects that it will run out of memory.
Formerly the program simply crashed. The new error message provide some suggestions on how to avoid the memory management problem.
have been added to the RSAP Controls Dialog box on the Results tab that allow the user to choose which reports they would like to
print. The list is context sensitive so only the available reports are shown (e.g., if you did not check the traffic sensitivity
analysis button there will be no traffic sensitivity report available, etc.)
- A button has been added to the RSAP Controls Dialog box
on the Settings tab that allows the user to select the default printer.
- The hints box at the bottom of the RSAP Controls Dialog box
has been enlarged and improved. A hint corresponding to any yellow or rose colored cell appears in the box if selected by the
user. The hint will also change based on the next likely step in the process.
- On the Results sheet a user input
cell has been added that allows the user to change the decision benefit-cost ratio. The default value is one but many times
States require a higher benefit-cost ratio in order to initiate a project. This allows the user to insert that number directly
so that the benefit-cost table directly shows the appropriate answer.
- In earlier versions of RSAPv3 the mid-life ADT was used to look
up the base number of expected encroachments. For low ADT situations this can result in inaccuracies since there is a “hump”
in the Copper encroachment data. Thus, if your ADT happens to be at the peak, RSAP will over predict encroachments over the
life. To correct this problem, RSAPv3 now calculates the expected encroachments at the beginning, end and mid-life as well as
seven other equally space periods (i.e., a total of 10) and then averages these to produce the average number of encroachments in
any year during the life.
- A warranting tool feature has been added to the Analysis settings. This allows users to run the same
RSAPv3 problem for a range of AADT values and percent trucks. If the Warrants checkbox is checked the run executes multiple
times for the ranges selected. The results are printed on the Results sheet and a button has been added to the Results tab that
allows these values to be viewed.
- On the Project Information page the “Open Existing Project” button has been improved. A second
dialog appears which allows you to choose the particular worksheets in the existing workbook to import. You can change which
worksheets are imported by checking or unchecking the boxes. You can also choose to erase any existing information in sheets
not being imported or leave the existing information in those sheets.
- The default vehicle types available have been expanded on the
“Traffic Information” page.
- Some of the hazard severities have been updated on the “Severity” worksheet.
- A bug was corrected that
sometimes resulted in the wrong alternative being selected in the Benefit-Cost Report on the Results Worksheet.
Changes in Release
- Some API calls were modified such that the same version of RSAPv3 will support both 32 and 64 bit computers.
The API calls relate to setting the process priority such that RSAPv3 does not go to “sleep” during long analysis runs. While
this solves the 64-bit compatibility problem it makes RSAPv3 incompatible with Excel12 which does not recognize those same API calls.
If you need to use Excel12 (i.e., you are using an old version of Windows) see Tip #4 for version that will run under Excel12.
