In Indonesia motorcycle (m/c) population now is around 70% from the total motor vehicle ownership. In some big cities, the statistics could be higher. A direct explanation for this, one can say it is due to a twin problem of low public transport performance and of high cost of car ownership, and/or low purchasing power. Many motorcyclists will switch to car drivers, once they get money to own car. Just for an illustration, owning car in Jakarta is a must, otherwise you will even get more costly 'daily transport cost'. In places where no public transport route available, 'ojeg' informal means of public transport i.e. motorcyle is widely available in a row. Accident in motorcyle come next after pedestrians. Other interesting sight, for you who ever visited the country, the brand in the row are mostly Japanese motorcyle ranging the name from Kawasaki, Yamaha, Honda, to name a few. which started to dominate other brand since the late 60's. In 1962, one still could found brand like , Victoria, Dulati, Augusta, HD, BSA, Ariel, BMW, Norton, NSU, Triumph, Harley Davidson, of course, all of which are very rare now adays. Now I am in the position to just start a study on issues of motorcycle use in general, particularly in urban area. The sponsorship is also being sought. If anybody could pin point some studies related to the issues, it will be very helpful. In my mind I would touch a bit on the histrory, m/c manufacturing or supply , m/c ownership modeling, safety and accident record, managing mixed traffic on the road, motorcyle dedicated lane, for example, and finally policy implication on encouraging using m/c both for private and more widely public transport.
