Measurement of tyre width and assembly type (single or double tyre)

Data provided by VTI vehicle position surveys is only relevant to the right hand side of a vehicles front wheels. No tyre width or type information is available. As parameters such as wheel paths (centre point of a single or double tyre) are considered important, it was decided to test a new system that could also record tyre width and type. However, measured tyre widths were narrower than expected. Initial thoughts are that this reduction is related to the shape of the tyre footprint. This means that results were not sufficiently accurate enough to distinguish between different sizes of tyres. Although exact tyre widths could not be determined, it was still possible to determine if tyre types were either single or double. In reality, there are large differences between single tyre widths and double tyre total widths. As similar large differences existed in the survey data, distinguishing between single and double tyre configurations was relatively easy. Approximately 30,650 vehicles were recorded and around 2,900 of these (9.5%) were classified as large goods vehicles (LGVs). Forty different types of vehicle were recorded. The percentage split between single and double tyre types was around 64% single and 36% double.
