JAMAR Technologies hand-held Traffic Data Collectors are known around the world as the easiest way to collect intersection data for quick analysis. Don't waste another minute manually transcribing numbers or typing them into a spreadsheet. Our hand-held data collectors do the tedious work for you, and data can be easily downloaded to a computer. These devices are easy to use, accurate and reliable. They will save you time and money.

 

Introduced in 2009, the TDC Ultra is the single most powerful hand-held traffic data collector in the world today. Not only does it do the most common of all manual traffic data studies - turning movements - it does an additional nine studies, making it the most versatile traffic data collection tool currently available. The biggest changes in the Ultra from the previous model (TDC-12) are the addition of a USB Port for downloading, the ability to collect Roundabout Movement Data and the ability to record data in Video Mode.

 

TDC-ULTRA w/ Video Mode

 

The easiest way to collect intersection data for quick analysis.

How the TDC Ultra Works

The  TDC Ultra is simple to use. An OFF/ON switch on top of the unit is used to turn it on and off. A 4-line by 20-character display helps you select the proper entries. All options are clearly displayed, with the currently selected option shown with a blinking highlight. The bottom lines of the display explain the option that is high­lighted.

 

Two buttons are all that are used to move from menu to menu, and to select from the options shown on the display. The TAB key is used to cycle through the options while the DO key is used to select an option. If you move the highlight too far and over-shoot the desired option, just keep pressing the TAB key until it is re-selected.

Turning Movements

The TDC Ultra is designed to make collecting turning movement data easy and accurate. The buttons are arranged to simulate a standard intersection. There are 16 buttons, with 12  normally used for the left, through, and right movements from each of the four approach directions. The additional four buttons are user-defined; they can be used for bicycles, pedestrians, or whatever you want.

Since the TDC Ultra looks like an intersection, doing a count is very intuitive. If a car makes a left turn from an approach, you simply push the button that shows a left turn from that direction. The TDC Ultra keeps track of everything else for you. At the end of every time interval, the data is automatically stored, so there is no need for technicians to take their eyes off the intersection to write down numbers.

While you record turning movements, you also have the option to classify the vehicles  recorded in up to three separate classes using the TDC Ultra's 'Bank' buttons. Trucks and other heavy vehicles can be stored separate from passenger vehicles, and percentage breakdowns can be determined.

In addition to the standard 3-class turning movement studies done by the TDC Ultra, you can also do enhanced turning movement studies 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.

Multiple studies can be stored in the TDC Ultra. For each study, the unit stores the date and time, the number of intervals used, a site code, and the data. At any convenient time, you can transfer the data to your computer through the USB port to our PETRAPro Software, which allows you to easily read, edit and store the data, as well as print reports, without ever having to manually enter data.

Easy Editing and Data Processing

The familiar spreadsheet style makes processing your data easy.

You can view and edit your data before printing, open multiple files at one time and move data from one file to another using standard Windows Cut, Copy and Paste commands. This makes it easy to compare or combine data between multiple files.

Turning Movement data can be processed for anywhere from one group of data up to 14 separate groups. With this ability, you can provide turning movements for all classes of vehicles in the Federal Highway Administration’s classification scheme.

Approach Wizard & Intersection Design

Once your Turning Movement data has been downloaded from the TDC Ultra to PETRAPro, you have many options for editing the data.

The new Approach Wizard allows you to quickly and easily modify the approach information for a file. With the Approach Wizard, you can create a 3 or 5 legged intersection with one click of the mouse. The wizard will automatically add or delete entire approaches, along with all references to the approach. In addition, you can use the Approach Wizard to delete sets of movements, change the order of approaches and rotate the data.

The Intersection Design allows you to configure the lanes of traffic approaching the intersection, giving

people viewing the data a clear view of the location where the data was collected. In addition, you can also add graphical icons and text information to the design.

Access Aerial Views & Include Digital Photos

Using your computer's Internet connection, any files that have GPS coordinates saved as part of their header can be used to directly access the Google Earth and Bing Maps mapping applications. With one click of the mouse, you can bring up an aerial view of the file's location, and map various other information.

In a unique feature available only in PETRAPro, the program allows you to attach digital photographs to your data file. This lets you give people a better sense of the data they are seeing by showing exactly how the intersection looks in real life.

The digital photos could be line-of-sight photos, or even aerial photos to give a bird’s eye view of the intersection. Whichever format you choose, the photos can be included with the reports you generate.

Roundabout Turning Movements

Modern Roundabouts are one of the more popular new developments in traffic engineering and are being installed at an ever increasing number of locations.

The TDC Ultra is designed to make roundabout movement data collection simple and accurate. The buttons are arranged to simulate the standard approaches to an intersection, which makes collecting the data intuitive. The actual recording of the data is very simple. Watch a vehicle as it approaches and track it as it moves through the roundabout.

For example, if it makes a right movement, press the right movement key for the approach it came from. If it makes a through movement, press the through movement key.

Stop Sign Delay

Are people complaining about how long they have to wait at a stop sign? The TDC Ultra lets you 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.  This is a simple study to understand. You press one key when a vehicle stops at the end of the queue, and you press another key when a vehicle (not necessarily the same one) crosses the stop bar. The TDC Ultra accurately measures the times when you press each key.

The analysis software then can calculate how long it takes each vehicle to progress through the queue and enter the intersection. The software also calculates the number of cars in the queue at all times.

Signalized Intersection Delay

Doing a Signalized Intersection Delay study is actually like doing two studies at once.

First, you are recording every vehicle that comes to the intersection from a specific approach as either having Stopped (the light is red or the light is green but a queue exists) or gone Through (the light is green and no queue exists). You only record a vehicle once - it is either Stopped or Through.

Second, while you are recording the approach vehicles the TDC Ultra will beep at a designated interval you have selected (between 10 and 16 seconds). When the beep occurs, you enter the number of vehicles in the queue at that exact moment.

These two procedures, taken together, provide enough information to give measurements of the delay.

Multi-direction Gap

Is there adequate time for pedestrians to cross a street? Does side street traffic have enough opportunities to cross over a main route? Will the traffic generated by a proposed new business have adequate time to make a left hand turn into or out of the driveway? A gap study helps you find out.

The TDC Ultra allows you to easily measure traffic gaps in up to two directions using just two buttons.

While you're recording the gaps for two directions, the Ultra will also automatically track and store combined gap information.

You can also record vehicle volumes while tracking gaps to get a complete picture of traffic patterns.

Spot Speed with Classification

Not sure if a full speed/class study is needed with an automatic traffic data recorder? The TDC Ultra can be used to get a quick snap shot of vehicle speeds.

The procedure implemented in the TDC Ultra is based on accurately measuring the time it takes a vehicle to travel over a known distance. You press one button when the vehicle passes over the start line you designate and then press another button when the same vehicle passes over the end line you designate, which is usually 100-200 feet away.

If you want to classify vehicles, rather than just pressing the same key when the vehicle crosses the end line you can press any of the 1 through 13 keys to classify it.

Vehicle Classification

Is heavy truck traffic slowing down traffic flow?

Perform a quick classification study to find out.

With the TDC Ultra, you can do three types of classification studies: one, Vehicle Classification using the Federal Highway Administration’s vehicle classification system (scheme F); two, Vehicle Classification using your own scheme; or three, any type of classification study you invent.

The first two involve assigning a vehicle type to each button. The FHWA scheme F uses 13 different classes of vehicles, based on the number of axles and the spacing of axles while User-defined classification schemes can have criteria other than axle number and spacing. The last type of study can have any kind of classification criteria, and count any type of event. It doesn’t have to be vehicles, or even traffic related for that matter.

Bicycle Classification

As the expansion of the country’s bicycle infrastructure accelerates, there has been a growing need for counting and classifying bicycle use. Much of this counting has been done with pen and paper, which often involves tedious transcribing.  Now there is a better way.

The JAMAR TDC Ultra hand-held data collector allows you to collect your data electronically, then download and produce reports in a matter of minutes.

With the TDC Ultra’s Bicycle Classification study you can define up to 48 separate categories of data types. The categories can be any type of data you wish to quantify, such as gender, age, helmet usage, sidewalk riding, wrong way riding, bicycles on buses, and more. The TDC Ultra also allows you to record full turning movements of bicyclists in up to 14 separate categories.

Saturation Flow Rate

How much are environmental factors impacting traffic flow at an intersection?

Don't rely on estimates to find the answer.

The TDC Ultra allows you to directly measure actual saturation flow rates, and also collect data for signal timings, arrival types, headways and lost time.

To collect the data, you wait for the signal to turn red, and watch for vehicles to come to a full stop in the queue. As they do, you press the Vehicle Stops key for the lane you are recording. When the signal turns green, you press the Green key and as each vehicle crosses the stop bar, you press the Vehicle Goes key. When the signal changes phases, you press the Yellow and Red keys, then repeat.

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.

Video Mode

An increasingly popular way to do turning movements and other traffic studies is to video record the location in question then later count the traffic while watching the video playback. The new Video Mode selection of the TDC Ultra is designed to let you do this in an efficient manner.

By using the special Video Mode now available you can compress (or extend) the time needed to do a count by running the video faster (or slower) than real time. You can also take breaks during your counting without disrupting how the data is stored.

This is accomplished by giving you control over the data interval timing, rather than having it be controlled strictly by the Ultra’s interval clock, as was the case in earlier versions of the Ultra’s firmware. You can now hit a key combination on the Ultra to immediately advance to the next time interval and continue counting without having to wait for the clock to count down.

With the Video mode you can complete a study in a fraction of the time it would take to do it in real time.

In addition to standard turning movement studies, the Video Mode of the Ultra also supports Roundabout, Vehicle Classification and Multi-direction Gap studies. All studies can be processed with JAMAR’s PETRAPro software.
