Motorcycles take a majority in road vehicle fleet of Vietnam, but there is no data on the number in current traffic circulation. This study presents a methodology to calculate this quantity (Mcir). Until now, in all existing works, the numbers of registered motorcycles are used instead of Mcir in ignoring the fact that after several years many vehicles have been excluded out of circulation. The use of correct Mcir could lead to better and more economical transport solutions. The paper also investigates the violations related to motorcycle driver license and shows that the level of such violations is serious. Furthermore, the paper shows methods to calculate the average use life, number of current users, and rate of users per one motorcycle. Especially, the short use life shows one sign for bad technical quality of existing vehicles. Last but not least, the paper presents a prediction of motorcycle number until 2020.
