For any vehicle not in the active class, you must also press one of the

class keys.

In Simultaneous mode, you hold down one of the 14 class keys while

you record the movement. When you release the class key, the active

class automatically reverts back to the default setting.

In Latched mode, you press the class key but do not have to hold it

down while pressing the turning movement key. Pressing the class key

automatically changes the Active Class. However, the active class does

not revert back to a preset default so you must press the class key each

time a different class makes a movement.

While you are recording your data, the last key combination you pressed

is shown on the third line. The class is shown ﬁrst, followed by the move-

ment number. The number in parentheses keeps track of the number of

times you pressed the same combination in a row.

Ending the Study

The Enhanced Turning Movement study data is stored on a vehicle-

by-vehicle basis, divided into one-minute intervals. Once you have

collected enough data, turn the TDC Ultra off.

Remember, the only way to stop a study is to turn the power off.
