New and Improved Features in PETRAPro
| IMPROVED Peak Information |
The improved peak information provides more information and presents it in an easier to understand format. Unlike
PETRA for Windows, the entire peak hour of data is shown in the peak report, and peak hour factors (PHFs) are
provided for every movement. Peak volumes can also be analyzed by group, with the percentage of each group (like
trucks) shown for every movement.
The first line of the analysis says ‘Peak Hour From’ and lists the start and end time that was picked for the analysis. It
also lists whether one or more peaks are being looked for in this time period. The second line lists whether the analysis
is for the Entire Intersection or By Approach and lists the actual starting time of the peak hour.
The next four lines list the actual volumes for the peak hour, with the high interval volume of each column in bold. This
is followed by each movement's total volume for the peak hour, and what percentage it is of the approach.
The next line list the PHF, or Peak Hour Factor, for each column of data. Following the PHF information is optional
group breakdown information. If this option is selected, this area will show the peak volumes on a group by group
basis, as well as a percentage breakdown.
In addition to the spreadsheet data, the plot of the peak data has also been improved. Multiple groups can be shown in
the plot, and additional labeling has also been added.
