Figure 5 - A breakdown of all registered vehicles in Hong Kong, showing cars to be the most substantial percentage of registered motor vehicles (Hong Kong Transport Department, 2006).
Unfortunately, the government records and surveys say little on which
vehicles are the most commonly used. Through interviews with transportation vehicle
drivers we determined the use of minibuses, buses, and taxis are immensely greater
than that of private vehicles, with some drivers driving for 20 hours a day. Taxi
drivers have told us they change their tyres every five or six months (See appendices J
through N for interviews with drivers). We also performed direct observation of the
road traffic in Hong Kong (See Figure 6) to determine the level of use of these
vehicles, to substantiate the government data (See Appendix O). Though this is not a
scientifically valid survey due to limitations with time, the data we acquired suggests
private cars should not be disregarded.
