I do not have Auto Turn Software. I have ACAD blocks that have several different wheel bases. Is there a standard Wheel Base (WB-67, WB-40, etc... reference AASHTO Chpt 2 pages 30-35) that I can use to check a fire truck entering a proposed fire station i am designing?
I have asked the fire chief to measure his wheel base...just thought there may be a standard WB measurement out of Autoturn or experience on the street.
Thanks!

Yeah, your best bet is the Fire Chief. You can measure the wheelbase, but some trucks have different turning radii for right and left hand turns. Find out the brand and model of the truck and see if you can get the info from the manufacturer. If not there may be another truck manufacturer that has a similar size/model. 字串7

Fire trucks are BACKED in unless through traffic is possible through the building.
