Abstract

The objective of this study was to develop the data necessary to produce the turning templates that would represent the minimum turning paths for critical design vehicles. This would include information concerning truck turning radii and offtracking for larger trucks with varying wheelbases operating in Kentucky. In order for the turning templates used for the various design vehicles to be based on the same procedure, data were produced tor design vehicles ranging from a passenger car to a combination truck with a 53 foot trailer. The simulation model used was the Truck Offtracking Model (TOM) and was developed by the California Department of Transportation.

The data obtained from the truck offtracking simulation program show that it can be used to develop turning templates that agree with those developed by AASHTO. The plotting information generated from this study can be used to prepare turning templates that can be used in the design process.
