New and Improved Features in PETRAPro
| NEW TDC Ultra Support |
PETRAPro contains support for the new 'enhanced turning movement' studies that can be performed using the new
TDC Ultra data collector. With this data collector you can record a full range of turning movements for up to 14 separate
classes of vehicles. PETRAPro will provide you with overall totals as well as a breakdown of each class. PETRAPro also
supports the new time-stamp raw data studies that can be done using the TDC Ultra.
The TDC Ultra replaces the older TDC-12 model of traffic data collector. The new TDC Ultra is the single most powerful
hand-held traffic data collector in the world today. Not only does it provide all the features of the old TDC-12, it adds to
them, creating the most versatile traffic data collection tool currently available.
The following studies can be done with the TDC Ultra and processed using PETRAPro:
Enhanced Turning Movements - The TDC Ultra gives you the ability to store turning movements for up to 14
classes of vehicles.
Vehicles can be classified based on the Federal Highway Administration’s standards, or by a user defined scheme of up
to 14 classes. This is accomplished by the addition of 14 class buttons at the bottom of the data collector. You also are
given several options on how to record the data with these keys.
Roundabout Turning Movements - One of the more popular new developments in traffic engineering is the
implementation of modern roundabouts. PETRAPro gives you a way to effectively present roundabout turning
movement data gathered with a TDC Ultra at these types of intersections.
Time-Stamped Raw Data - Is there a specific type of data collection that you would like to do that the data collectors
don’t? Don’t let this stop you from getting your data, just use the TDC Ultra’s time-stamping capability. In this mode,
whenever a key is pressed the unit stores the key number and the exact time it was pressed. Each key press is stored
with a time stamp accurate to one-hundredth (.01) of a second. This raw data can be downloaded and exported into
Excel or other programs for custom analysis. Now you can do literally any type of data collection using a TDC Ultra and
your own program.
Stop Sign Delay - Accurately record queue lengths and vehicle delays at a stop sign controlled intersection. Data can
be collected for one or two lanes using just two or four keys. Can also be used at low volume signalized intersections.
Signalized Intersection Delay - Collect data that can be analyzed for several delay parameters. This data collection
uses well known traffic engineering techniques to gather usable data in a matter of minutes.
Vehicle Classification - Perform classification studies with up to 16 different classes for 1, 2 or 3 directions. Classes
can be user defined or based on FHWA standards.
Spot Speed with Classification - Get a quick snap shot of vehicle speeds without having to install an automatic traffic
recorder. Studies can be for speed only, or speed by vehicle classification.
Multi-direction Gap - Measure traffic gaps in one direction, or two directions with a combined gap. You can also
record vehicle volumes while tracking gaps.
Saturation Flow - Don't rely on estimates when doing analysis. The TDC Ultra allows you to directly measure actual
saturation flow rates, and also collect data for signal timings, arrival types and lost time.
