The paper presents the results of the development of a standard driving cyc
le in the urban areas of Hong Kong. On-road speed-time data were collected
by an instrumented diesel vehicle along two fixed routes located in two urb
an districts in Hong Kong. The collected data were analyzed and compared wi
th mandatory driving cycles used elsewhere. It was found that none of these
mandatory cycles could satisfactorily describe the driving characteristics
in Hong Kong. A unique driving cycle was therefore developed for Hong Kong
. The cycle was built up by extracting parts of the on-road speed data such
that the summary statistics of the sample are close to that derived from t
he data population of the test runs. (C) 1999 Elsevier Science Ltd. All rig
