Parking Lot Geometric Design

Parking Lot Geometric Design

Parking Lot Geometric Design

(OP)

Angle parking at 71°
What would be the minimum practical one-way aisle width?
I'm trying to live with 15'

I understand that this can vary from one jurisdiction to another, my concern however is operational! Can cars get in and out of these stalls with a 15' wide aisle with relative ease, and is anyone aware if such tight dimensions have been allowed anywhere before?

Thanks a lot!

RE: Parking Lot Geometric Design

In this area (Anchorage), for 70 degree parking, would be required to have 19' wide aisle (for 9' wide stall) or 18' (for 10' wide stall), except that an employee parking lot could use a 17' wide aisle, and 14'-1" wide aisle for a compact car space. So I'd say 15' sounds awfully tight for everyday traffic, standard vehicles.

CarlB, thanks a lot for your valuable response. As  a result of various comments I received the above parameters were modified as follows:

Stall: 8.5'x18'
Angle: 65°
Aisle: 17'

Still tight! However, was able to document these parameters as acceptable minimums! Based on geometrics and experience would you consider these new parameters as acceptable operationally!

Again thanks a lot for keeping these discussions lively and prompt!
