Data Analysis Software for Hand-held Data Recorders

PETRAPro is the software for analyzing data gathered with the TDC-12 or DB-400 hand-held data collectors. This program processes data that includes standard Turning Movement, enhanced Turning Movement, Vehicle Classification, Multi-direction Gap, Stop Sign Delay, Signalized Intersection Delay, Spot Speed and Saturation Flow Rate.

A variety of reporting options are available and the data can also be exported into numerous other programs.

Released in 2004, this program replaced the older PETRA for Windows software, which was originally introduced in 1998. PETRAPro offers new features and improvements to the older PETRA for Windows software.

The program allows you to create a variety of reports and graphs. Finished reports can also be saved in Acrobat PDF or Text format for easy electronic transfer. PETRAPro will also read files created with PETRA for Windows and PETRA DOS.

Supported Studies

Standard Turning Movements

Turning Movements are the studies most commonly used with PETRAPro, and as such, the program gives you a great deal of options on how to present your data. Intersections can be done with up to eight separate approaches, with a wide variety of movement directions.

Enhanced Turning Movements

Take your turning movement studies to a new level by classifying a full range of vehicles as they make movements. Up to 14 separate classes of vehicles can be recorded with their turning movements.

Vehicle Classification

Select from FHWA Scheme F or define your own. Up to 3 different directions can be reported separately or combined. Classify by vehicle type, occupancy, number of axles or any other scheme you need.

Multi-direction Gap

Report traffic gaps in 2 directions and combined. Group gaps in 15 two second bins. One extra bin is provided for volume totals.

Signalized Intersection Delay

Report stopped delay and approach volumes at a signalized intersection. Statistical method uses 10 to 16 second samples of intersection queue size.

Stop Sign Delay

Accurately report on vehicle delay at stop sign controlled intersections. Uses real-time data gathered with JAMAR count boards to provide the most accurate measure of intersection delay.

Spot Speed with Classification

Reports speed by class. Define 1 to 13 classes. Input data from a JAMAR board or use your radar/VASCAR data. Each class is reported individually or combined. Several graphs and reports give you immediate analysis of your speed data.

Saturation Flow Rate

Produce reports for not only saturation flow rates, but also signal timings, arrival types and lost time.

Raw Data Collection

Create your own data analysis studies using the time-stamping feature of the raw data collection. In this study, every button you press is assigned a time stamp of when the button press occurred.

PETRAPro software supports the JAMAR TDC-12 and DB-400, as well as the TDC-8, DB-100, IMC-IV and IMC-4.

Features of PETRAPro

Graphical Interface

PETRAPro provides a new Main interface screen that contains shortcut buttons to some of the program's most used features. This graphical interface allows you to quickly and easily access download, file open, and preferences screens, as well several others.

Quick Downloading

Easy point and click selections from PETRAPro's toolbar icons make functions like downloading a count board easy to do. Once you have setup the download screen with the settings desired, simply hook up your board and start downloading.

Familiar File Retrieval

PETRAPro allows fast, easy retrieval of files using a familiar Windows Explorer style. Save your count files to your local or network hard drives. Import and export many different file formats including PETRA for Windows, PETRA DOS, IMC, AAP and ASCII.

View Multiple Files

The program allows you to view multiple files on the screen at the same time in a variety of formats. Compare data collected recently with older files. Quickly move data from one file to another or to any other Windows program that supports standard cut, copy and paste functions.

Plot Data

Plot the data in an intersection form, with each approach broken down by movement. Up to eight approaches can be included in a plot, including diagonal approaches. The data plot can be done for both the overall data and peak hour data of a file, and can list up to 14 separate classes of vehicles.

Graph Data

Show data in a graphical form, using built-in graph formats or by creating your own. The pre-designed Variable Width Graph uses thick and thin lines to represent traffic volumes. You can also create your own custom graphs from any portion of the data in a variety of two-dimensional and three-dimensional formats.

Intersection Design

Design an intersection to look like the actual site of the data collection, with multiple inbound or outbound lanes, turn lanes and center dividers. Graphical icons can also be included on the design. These icons include lane markings, street signs, control devices, data collection locations, or customized ones you create. You can also add text information to the design.

Include Digital Photograph

Show exactly how the intersection looks in real life by including a digital photograph with the report. The digital photo could be a line-of-sight photo, or even an aerial photo to give a bird’s eye view of the intersection. Whichever format you choose, the photo can then be included with the reports you generate.

Customized Reports

Go from data collection to report generation in a matter of seconds. Format your printouts with a graphical logo of your organization, different fonts, sizes, styles and colors to make your reports stand out.
