Design Vehicle WB-67 Turn Radii All ramp terminal intersections are roundabouts designed per chapter 1320 and use of auto turn templates for design vehicle Intersection Radii - Left Intersection Radii - Right Intersection Angle All ramp terminal intersections are roundabouts designed per chapter 1320. Intersection Sight Distance Barriers. The 1990 AASHTO Policy adopted a WB-62 and a WB-67 referred to as Interstate Semitrailer(s). Jack Leisch passed away in 1991 too late to incorporate them into the set of templates. The templates were contained in a 5-ring binder and sold by Jack E. Leisch and Associates directly or by consignment to the Institute of Transportation Engineers.
CadTools (ToolBox) is a software developed for Civil Engineers using AutoCAD or ZWCAD.
Aashto Wb 67 Turning Template
With CadTools you can create your own surface models based on objects in the drawing or import triangles from DWG (other civil software). You can create profiles and cross-sections of multiple surfaces, calculate volumes and plot contours.
Vehicle turning software simulates vehicle turning at low speed and determines vehicle tire tracking and swept paths. Its useful in the design of road intersections, parking lots and other vehicular facilities.
Aashto Wb 67 Truck Dimensions
10 default types of vehicles are supported. Every vehicletype has its own figuration ruled by a combination of segments, the first segment is the truck, the second is either a trailer or a tow bar and so on. You can easily create your own vehicles by copying a existing vehicle and change parameters. You can use up to 4 segments including the truck, that would give you a Triple trailer and we think that would cover most of the common situations.

Single Car Driveway Widths
A single car driveway width should be 10' wide, anything less
than 10 feet will be too narrow to drive or park on comfortably.
12' is often used for added comfort and assuring to get out of your vehicle without stepping on the lawn or landscape.
If the driveway is surrounded by walls over 8' high, then 14' wide is recommended to open the car doors and exit the vehicles without damaging the doors. These specifications will accommodate all cars large or small and full size pick-up trucks & SUV's
8' - 9' wide driveways are not practical and should only be used if there is no other options. People have told me that they only need an 8' wide driveway because they have a small vehicle, but what happens if they buy a new vehicle or sell there home, will the new owners have small cars too?
Driveway Lengths
Rule of Thumb
18 - 20' Long per vehicle
Driveways should allow 20' of length per vehicle. Every 20 feet of driveway will accommodate all cars large or small and full size pick-up trucks & SUV's. This will allow room to walk between vehicles and park far enough from the garage door to allow foot traffic.
Be sure to allow 6-12 feet at your driveway entrance for foot traffic on the sidewalk. The sidewalks are owned by the state and local governments even if there are no sidewalks on your street now, there could be someday, and you don't want to have your cars parked in the way of pedestrians on state or town property.
You will need to check with your local town or state government as to how much sidewalk area they own and allow for sidewalks to be installed if not already in place. Never take the measurement from the street to the garage, but from the sidewalk or property line to the garage.
As a general rule of thumb every vehicle will fit comfortably on 10'W x 20'L area or 3.05m x 6.10m
Of course there are exceptions to every rule, and some might say that 18' long is enough or 16' will work, well these numbers will work in a parking lot that is trying to cram as many cars as possible. But for your home you want your driveway to be comfortable and not crammed like the local malls.
An 18'L x 9'W car stall will work well with a small car but as I mentioned earlier what if you don't have a small car the rest of your life or a visitor has a full sized pick-up truck! He may have trouble parking on 18' x 9'.
Double Wide Driveway Width
Rule of Thumb
20-24' Wide
Ideally 20' wide is a comfortable width for a double car driveway.
20' will allow you to park side by side or serve as a passing lane on a long driveway. A 24' width is needed if you have walls on both sides of where you will be parking, to allow the car doors to open without banging the walls.
- 18' wide is also adequate as a passing lane but 20' is best for parking vehicles side by side.
- 16' is just too narrow for passing and parking and should only be used when there are no other options.
- 15' wide is too narrow for a double wide driveway and too wide for a single car and should not be used as a driveway dimension unless there is a reason.
- 10 - 12 feet wide for a Single Car driveway
- 14 feet wide if Surrounded by Walls
- 18 - 20 feet wide for a Double Wide driveway
- 24 feet wide if Surrounded by Walls
- 30 feet wide for a three car wide driveway/parking area
- 40 feet wide for a four car wide driveway/parking area
- Allow 10' for each each additional desired car width
Turn Around Area
Rule of Thumb
10' x 20' Single
20' x 20' Double
ATurn around is an area in which you can back your car, allowing you to drive forward out of your driveway without having to back down a long driveway or on to a busy street. Turn arounds are single or double car wide (10 or 20 feet) 18-20 feet deep (long) to accommodate additional parking as well as serve as a turn around. 20' x 20' is the rule of thumb for a double There is also a half turn around which will only serve as an area to back the rear end of the vehicle just enough to make the swing, however there is no additional parking on these 10 - 12 feet deep turn arounds. The most important thing to understand about a turn around is that they need to be placed at least 20 feet away from the garage door to make them practical. Most people park vehicles in front of the garage, so in order to back into the turn around you need to allow 20' or more away from the garage door to make it feasible. Minimum turning radius should be 17' Or 34' feet inside dimension. Take a 17' piece of string, nail one end to the ground, and use it as a compass, and you will get your 17' Radius!Which is a comfortable turning radius for most vehicles!
