To ensure that the Drive-Thru Director accounts only for complete and valid drive-thru transactions,
DTD loop activations at your menu board and pickup window must meet certain criteria. These criteria help DTD
provide exceptions for unusual events such as when a vehicle travels through your drive-thru without stopping, or when a vehicle unexpectedly leaves your drive-thru queue. These validating criteria include roll-up delays, roll-off delays, and a minimum total-time. Read below for a further explanation about roll-on and roll-off delays, minimum total-time, and to discover what we mean by "complete and valid" drive-thru events.
Roll-Up Delays and Defaults
A roll-up delay is the minimum amount of time before vehicle detection is considered valid.
For example, if a vehicle is detected at your menu board or pickup window but the vehicle is not continually
detected for the minimum time-requirement, the vehicle is not considered a valid detection, and its time will not
appear on your reports.
Roll-up delays are configurable for each segment of your drive-thru and are determined by your brand.
The DTD has set roll-up delay defaults for both your menu board and pickup window. The DTD roll-up delay defaults are as follows:
Roll-Off Delays and Defaults
A roll-off delay is the minimum amount of time before vehicle detection is considered complete. Roll-off delays are designed to aid in sensor continuity. If a vehicle detection quickly starts and stops, or "flickers” for less than the configured amount of time, the original vehicle detection continues as a single event and not as two individual events.
Roll-off delays are configurable for each segment of your drive-thru and are determined by your brand.
The DTD has set roll-up delay defaults for both your menu board and pickup window. The DTD roll-up delay defaults are as follows:
Minimum Total-Time and Default
A complete and valid Drive-Thru Director drive-thru event requires BOTH a complete and valid menu board event
AND a complete and valid pickup window event. The combined total-time of the completed menu board and pickup window events MUST meet a minimum total-time. If your combined menu board and pickup window total-time does not meet the minimum total-time, the drive-thru event is not considered complete and valid, and will not appear on your reports as a completed drive-thru event.
The minimum total-time is calculated by combining your complete and valid menu board event time and your
complete and valid pickup window time. The default DTD minimum total-time is as follows:
Complete and Valid Events
A complete and valid Drive-Thru Director drive-thru event is comprised of other complete and valid events. For example, you must have a complete and valid menu board event and a complete and valid pickup window event to have a complete and valid drive-thru event. The chart below explains what is necessary to have a complete and valid event for each segment of your drive-thru.
Your total number of complete and valid drive-thru events for your day-part and overall day is depicted on your day-part and all-day tiles as shown in the image below.
