Road Traffic Volumes [THA17]

Please see THA12 for data prior to 2014.
1. Vehicle population represents annual average for each year.
2. The totals on this table may vary slightly due to rounding.
3. Vehicle kilometre estimates and average kilometre estimates for motorcycles, tractors and machinery maybe unreliable as minimal odometer data is available for these categories of vehicles.
4. Vehicle kilometre estimates and average kilometre estimates for private cars less than four years old are based on the extrapolated trends of older private cars (private cars less than 4 years are not subject to the NCT).
