Traffic Engineering in the Palm of Your Hand

The TDC-12 is the single most powerful hand-held traffic data collector in the world today. Not only does it provide all the features of our DB-400 data collector, it adds to them, creating the most versatile traffic data collection tool currently available.

At any convenient time, you can transfer the data to your computer through the serial port to our PETRAPro software. The PETRAPro software allows you to easily read, edit and store the data, as well as print a variety of reports and graphs, without ever having to manually enter data.

Enhanced Turning Movements  - With the DB-400 you can collect turning movement data for up to three separate classes. But, what if you need to know turning movement volumes for a full range of classifications? The TDC-12 answers this by giving 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.

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-12 allows you to directly measure actual saturation flow rates, and also collect data for signal timings, arrival types and lost time.

Travel Time and Delay - Use with a vehicle installed transmission sensor to record travel time and delay data. Identify problem areas where excessive delays occur and optimize signal timings accordingly. Also compare before and after results when making changes to timings. (Requires our PC-Travel software.)

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-12’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-12 and your own program.
