Frequently Asked Questions
How is PETRAPro different from PETRA for Windows?
PETRAPro is a completely new program that provides greater reliability and performance, while retaining the style and ease of operation that PETRA users have come to
appreciate. It offers new features and improvements to features found in PETRA.
With what operating systems is the program compatible?
PETRAPro is compatible with all Windows Operating Systems 98 or higher, including Windows 98, Windows 2000, Windows ME, Windows NT, Windows XP, Windows Vista
and Windows 7.
My computer does not have a serial port for download. What can I do?
Most older JAMAR equipment that interfaces with a computer use a serial (Com) port to do so. However, if you do not have a serial port on your computer (or there is a conflict
with another device), you can use a USB port by using a USB to Serial Adapter. These devices allow serial peripherals, like JAMAR equipment, to interface with a USB port. Full
details.
When I run the program it asks me to check my preferences and when I hit OK I get the following error: 'An error occurred in PETRA module SETTINGS_SAVE'. What's
wrong?
This error is typically related to a security setting in either the Windows Vista or 7 operating system. More details...
How do I find the version number or serial number of the program I am using?
To locate the version or serial number, click on the Help menu and select About PETRAPro.
I am having trouble downloading or processing my data and I need to send in the temp file (jamar.jcd) and I don’t know how to do this.
The default location of the .jcd file "JAMAR.JCD" is C:\Program Files\JAMAR\Petrapro, however you can change the location where they are downloaded to so you may need to
check that particular setting. You can check where the .jcd files are downloading to by opening PETRAPro and going to File=>Aquire=>JAMAR.
This will bring up the download screen. On that screen there is a field that says “Sending Temporary file to:…” and there is a data path listed. This is where your .jcd file is going
each time you download.
To email the .jcd file to us at JAMAR just compose an email in your email client and use the attach function within the email client and simply browse to the specified location
and select the file JAMAR.JCD and email it to support@jamartech.com. Be sure to put your Name and contact info as well as a brief description of what exactly is happening
and any error messages your receiving.
***IMPORTANT***
The .JCD file is re-written each time you download, so if you need a JCD file from counter x, but have downloaded Y and Z since then, you would need to “re-dump” counter x to
have the JCD file be correct.
What is the PHF? How is it calculated?
PHF stands for Peak Hour Factor, a number which represents the relationship between the peak hour volume and the maximum rate of flow within the hour. Full details.
The In and Out totals on the intersection plot appear to be reversed. Are they?
No. The In and Out listing of the Intersection plot are always in reference to the intersection itself. Full details.
When I attempt to use the program, I get an error message regarding 'access rights' either when just starting the program or trying to open files. Why is that?
In most cases, this is related to the permissions you have been assigned as a user on your computer. Full details.
In gap studies, the bins used are 2-3, 4-5, 6-7, etc. How does the program treat gaps that fall between whole numbers, like 3.2, 5.5, 7.8 etc?
PETRAPro truncates, rather than rounds, any fraction of a second from the end of the value, so 3.2 would be recorded as 3, 5.5 recorded 5 and 7.8 recorded as 7. Full details.
My gap studies wont show any combined gaps? I did a gap study and now when I look at the data there is all zeros for my combined gap, what has caused this?
The primary reason this would happen was if the Turning Movement Board that collected that data was set for only two data tiers, rather than the three that are needed to collect
combined gap. There is no way to fix data already collected with this issue. But we can fix the board so it does not happen again.
Turn the board on and go to Utilities, then options, then Tiers. 2 Tiers will probably be blinking, select 3 tiers and hit ok. Now the third tier will be active and you will get your
combined gap when you do your next gap study.
How does the Save Print Defaults button in the print Setup work?
The Save Print Defaults button is designed to allow you to save a specific set of print setup defaults to be applied to new files that are created. Full details.
The Print and Preview buttons in the print setup are not active (grayed out) and can't be clicked. Why?
This generally occurs if no 'groups' have been selected yet in the Combine Groups field. You must select at least one group in order to produce a report. The Print and Preview
buttons will not be active until at least one group is selected.
An error saying I am not licensed to process counts appears when I try to open a data file. I have been using the software for years, why is this message appearing?
This error message typically occurs when a file gets corrupted. Generally there is no way at this point to recover these lost files, other than going to backup copies. To check
that this is the issue, try to open several other files you have. If one or just a handful give the error, but others open fine, then the files are corrupted.
To guard against more files getting corrupted you will want to make a new folder for your traffic count files that is NOT inside the folder that contains the corrupted files. Then
take all your good files and copy them to this new folder and then delete the old folder that contains the corrupted files.
Many times you can also see the effect of corruption in a files size, many times a corrupt file will read as 0 or 1 KB.
