【Abstract】 Research is made on the bus driving condition and the road codition in Shanghai.With the introduction of the concept of the coverage rate,frequency of section in traffic and equal probability sampling method,a testroute which can highly improve coverage rate is chosen.Investigations are carried out on bus lines and data are collected.Based on the method of short trip,principal composition analysis and clustering theory,an actual bus drivingcycle for Shanghai is constructed.更多还原
