A Better Alternative to the Traditional Plastic Approach Turning Templates operate in any CAD environment and are used by transportation and traffic engineers in the design of roadway facilities involving vehicle access evaluations. Turning Templates can be used for projects such as: roundabouts, intersections, loading bays, gas stations, parking lots and industrial/commercial facilities. Created using AutoTURN for maximum reliability Produced using AutoTURN ® software, Turning Templates adhere to selected regional transportation agency design standards from North America (AASHTO, CALTRANS, TAC), South America, Europe, and Asia Pacific.

Contents. Usage The term turning radius is a technical term that has become popular automotive jargon. In the jargon sense, it is commonly used to mean the full diameter of the smallest circle, but in technical usage the turning radius still is used to denote the radius. The less ambiguous term turning circle avoids the mistaken jargon use of the word 'radius'.
As an example, refers to a curb-to-curb turning circle of a 2008 Cadillac CTS as 35.5 feet (10.82 m). But the terminology is not yet settled.
AutoChannel.com refers to turning radius of the same car as 35.5 feet (10.82 m). It is often used as a term rather than a. For example, a vehicle with a very small turning circle may be described as having a 'tight turning radius'. Curb to curb Two different measurements can be quoted for a vehicle. A curb or curb-to-curb turning circle will show the straight-line distance from one side of the circle to the other, through the center.
The name 'curb-to-curb' indicates that a street would have to be this wide before this car can make a u-turn and not hit a street curb with a wheel. If you took the street curb and built it higher, as high as the car, and tried to make a u-turn in the street, parts of the car (bumper) would hit the wall. The name wall or wall-to-wall turning circle denotes how far apart the two walls would have to be to allow a u-turn without scraping the walls. One can find these two ways of measuring the turning circle used in auto specifications, for example, a van might be listed as having a turning circle (in meters) of 12.1(C)/12.4(W).
A notable exception in this description is of vehicles that are capable of around their central axis, such as certain and as they do not follow a circular path as they turn. In this case the vehicle is referred to as a ' turning radius' vehicle. Some used in the have a 'round' mode which allows them to spin around their by allowing inverse rotation of their front and rear wheel sets, effectively giving them 'zero' turning radius.

Section 7: Minimum Designs for Truck and Bus Turns Overview This section contains the following information on minimum designs for truck and bus turns:. application. channelization. alternatives to simple curvature. urban Intersections. rural Intersections.
Application There are no firm guidelines governing the selection of the type of large vehicle to be used as a design vehicle. Factors that influence design vehicle selection are as follows:. the type and frequency of use by large vehicles. consequences of encroachment into other lanes or the roadside. availability of right-of-way. Functional class of intersecting routes and location (urban versus rural) affect this selection in a general sense. Project-specific traffic data, specifically the frequency of use by the various design vehicle classes, is often the most important consideration in the selection process.
The Transportation Planning and Programming Division (TPP) may be contacted to obtain volume data for the various vehicle classes. Minimum turning path templates for single unit trucks or buses, semi‑trailer combinations with wheelbases of 40, 50 and 62 ft 12.2, 15.24 and 18.9 m, and double-trailer combination with wheelbase of 67 ft 20.43 m are shown in Figures 7-1, 7-2, 7-3, 7-4, 7-5, and 7-6 respectively. The AASHTO publication A Policy on Geometric Design of Highways and Streets provides additional information on turning paths and turning radii of these and other vehicles.

Channelization Where the inner edges of pavement for right turns at intersections are designed to accommodate semi‑trailer combinations or where the design permits passenger vehicles to turn at 15 mph 20 km/h or more (i.e., 50 ft 15 m or more radius), the pavement area at the intersection may become excessively large for proper control of traffic. In these cases, channelizing islands should be used to more effectively control, direct, and/or divide traffic paths.
Physically, islands should be at least 50 ft 2 4.5 m 2 in urban and 75 ft 2 7.0 m 2 for rural conditions (100 ft 2 9.0 m 2 preferable for both) in size and may range from a painted to a curbed area. Alternatives to Simple Curvature To accommodate the longest vehicles, off-tracking characteristics in combination with the large (simple curve) radius that must be used results in a wide pavement area. In this regard, three‑centered compound curves, or offset simple curves in combination with tapers, are preferred since they more closely fit the paths of vehicles. Table 7-2 shows minimum edge of pavement designs for right turns to accommodate various design vehicles for turn angles varying from 60 to 120 degrees. (US Customary).
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? 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'. 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. A Turn 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.
. Glossary. Have you ever got caught midway through a u-turn only to find out the vehicle you are driving forces you to perform an unwanted three-point-turn because the vehicles turning circle is larger than you expected. The turning circle is the measure of how easy the car will be to park or to perform a U-turn.

The term “turning circle” refers to the minimum arc a vehicle will turn through with the steering wheel turned to the full lock position. The turning circle is usually measured kerb to kerb in metres using the front outside tyre. Sometimes only the radius is given, so for the diameter, multiply the radius by two.
Usually, the smaller the vehicle, the smaller the turning circle; however front wheel drive cars are usually the ones worse off when it comes to a turning circle as the front wheels are unable to turn as much as the front wheels on rear wheel driven cars. Four wheel drives are notorious for having large turning circles, particularly the Toyota Hilux, which has a turning circle diameter of over 12.2m. It is built for the wide open spaces, obviously! If we compare that with the new Suzuki Swift, which has a turning circle of 9.4m, you can see which of the two will be easier to park at the shopping mall, and easier to swing through a u-turn.We hope that helps answer the question ‘What is What is a Turning Circle?’!
