| Abstract: | A practical methodology for constructing a representative driving cycle reflecting the real-world driving conditions is developed for vehicle emissions testing and estimation. The methodology tackles three major tasks, i.e., data collection, route selection and cycle construction. Both car chasing and on-board measurement techniques were employed to collect vehicle speed data. Route selection was based on the records of average annual daily traffic of the road network between major residential areas and commercial/industrial areas. A variety of parameters were employed as the target statistics characterising the driving pattern in the construction of driving cycles. The performance value and speed-acceleration probability distribution were utilised to determine the best synthesised driving cycle. The method is easy to follow and the driving cycles are comparative to other renounced cycles. |
