Development of a driving cycle for Hong Kong

The paper presents the results of the development of a standard driving cycle 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 urban districts in Hong Kong. The collected data were analyzed and compared with 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 the data population of the test runs.
