Light rail vehicles forced to turn necessarily use multiple travel lanes, and tracks must be designed to accommodate inherent turning constraints. βF = Steering deviation (deg) document.write(' ') Vehicle turning radius varies greatly, depending on streetcar/LRV age and design. The turning geometry of a 60-foot articulated bus is quite similar to a 40-foot bus, the primary difference being the vehicle’s ability to pivot around the center bridge plate.
The turning radius depends heavily on specifications of your vehicle like the vehicle size, the amount of axles, the steering and the wheelbase. 'a0 = Theorectical value for outer steer angle, © Copyright 2000 - 2020, by Engineers Edge, LLC www.engineersedge.com All rights reserved However, the following formulae can be used for estimation purposes: Calculator Preview: Vehicle Turning Circle Equations and Calculators, Theorectical value of the outer steering angle, j = Distance between steering axles (mm) If you are looking into calculating the turning radius of a vehicle, you might want to start with downloading a free demo of AutoTURN. In modern days a computer is used to calculate the exact turning radius of a specific car or truck.
Turning Radius calculation: Introduction This article describes the calculation of the turning radius of a car or bicycle. Transoft Solutions has built its reputation as a leader in the development of quality-enhancing and time-saving CAD software for the engineering community. Ikt = Wheelbase center to center (mm)
American Association of State Highway and Transportation Officials (2014). '16 Batmobile: 128.82: 84.67: 29.39: 34365: 2.342: 2.014: 2.25 '89 Batmobile: 127.93: 83.28: 31.30 Downloads Due to their extended length and capacity, articulated buses are not characteristically employed on smaller streets where fewer riders are likely to accumulate, so tight curb radii are a less significant consideration.

This is achieved by making simple arrangements in the various components of the steering column. ro = Scrub radius (mm) the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road.

A standard three-section LRV centerline turn radius is 82 feet, though streetcars may have a smaller centerline radius between 45 and 60 feet. Transit vehicles typically require an effective turning radius of approximately 20–30 feet, depending on lane width and presence of curbside parking lanes or buffer distance.
