Vehicle Kilometer of Traveled is one of most meaningful indicators to represent road transport in particular area. It is an essential data in order to observe vehicle usage and estimate amount of CO2 emissions from road transport. Especially, in developing cities, estimation of CO2 emission based on VKT is the applicable approach. However, it is not sufficiently available in Thailand. Therefore, in this study, VKT by vehicle types were measured by applying method based on records of odometer and conducting driver’s interview survey in Khon Kaen City, Thailand, as case study. Results revealed that accumulated VKT has high positive relation with vehicle age but annual VKT have high negative relation with vehicle age. Moreover, the study surveyed fuel consumption per distance to develop fuel consumption rate by vehicle type. Results revealed that fuel efficienciess of Sedan and Van & Pickup Truck are higher than twice of Motorcycle.
