In this study, I use the estimated figures from ADB than the official police reported fatalities and injuries for the year 2003.1 have applied the adjustment factors to the data given in other years. 

The number of people killed in accidents cannot be directly compared since the individual definition of road accident deaths differ or is underestimated. As defined by the United Nations Economic Commission for Europe, a road death is a victim of a traffic accident who dies at the scene or within 30 days from the date of the accident. However, not all ASEAN countries apply this 30-days definition for instance in Laos, Thailand and the Philippines, died on the spot in Vietnam, within 24 hours of an accident, while other ASEAN countries follow the European criteria of 30 days (see Table 4.2). The fatality figures from Laos, the Philippines, Thailand and Vietnam should be all adjusted to the 30-days definition and multiplied by a factor of more than one. If this is not done, then such non-uniform definitions can considerably affect the level of accident statistics. However, this 30-days correction factor is not used in this study since I already performed the estimated figures from ADB to the data. It is unnecessary to apply more than one correction factor to the data. 

The two-wheeled number is underestimated in some ASEAN countries as many of these vehicles are not registered. Their percentage of the total vehicle fleet in the country may be even higher than is shown in the data. According to the same study from ADB (2004), it found that an additional 465,783 motorcycles were identified and unregistered in Myanmar, which almost doubled the official registered motorbike vehicle fleet.
