How Many Vehicles Do You Need to Store in a Drive Through Lane?
Since my days reviewing site plans in Maple Grove a decade ago, I’ve had a nagging question – how much storage should be provided in a drive through lane? There was an article published in the ITE Journal in 1995, but that is out of date. Mark Stuecheli prepared a study about banks and coffee shops in 2009 that was presented at the ITE Annual Meeting. But nothing comprehensive like ITE’s Parking Generation report.
So we’ve gone ahead and laid the ground work by preparing the 1st Edition of the Drive-Through Queue Generation report. We collected video with our COUNTcams at drive throughs for two days at a minimum of six locations for five different land uses (meaning each land use has at least 12 maximum queue data points). We also incorporated Mark Stuecheli’s data (thanks Mark). We watched 1220 hours of total video (which we did on fast forward in about 120 hours with our PC-TAS software). Then we put the above report together – from start to finish in three weeks (and yes we’re cracking open the beer this afternoon to celebrate).
So what did we find? Here are our recommendations based on the 85th percentile maximum queue lengths.
Recommended Drive Through Vehcile Storage (total vehicles, independent of # of lanes)
- Banks – 8 vehicles (160 feet)
- Car Washes – 7 vehicles (140 feet)
- Coffee Shops – 13 vehicles (260 feet)
- Fast Food Restaurants – 12 vehicles (240 feet)
- Pharmacies – 5 vehicles (100 feet)
