Standard Turning Movement Studies

NOTE: This chapter deals with data collection for Standard Turning Move-

ment studies, in which vehicles can be classiﬁed by up to three different

groups using the Bank 1 and Bank 2 keys located near the top of the TDC

Ultra. For information on Enhanced Turning Movement studies, in which

vehicles can be classiﬁed by up to fourteen different groups using the 14

yellow keys located near the bottom of TDC Ultra, refer to chapter 4.

The TDC Ultra is designed to make turning movement data collection simple

and accurate. The buttons are arranged to simulate a standard intersection,

which makes collecting the data intuitive. 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 buses, trucks, bicycles, pedestrians, or whatever you want.

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.

The TDC Ultra can also double or triple the number of movements counted

from 16 to 32 or 48 by using the unit’s two BANK keys in conjunction with
