With the introduction of the concept of the coverage rate and frequency of section in traffic method, the typical public traffic routes are selected. Investigations are carried out on bus lines and actual operation data are collected. The principal composition analysis and clustering theory are used to construct a driving cycle in this paper. The research shows that it is a feasible method to using...
Based on a large number of experimental data, a simple construction method of driving cycle named fixed step intercept is used to construct the driving cycle of Hefei. In data processing, three definitions of running statuses are defined. The results and errors of different definitions of running statuses are analyzed through 11 characteristic parameters which reflect the road traffic characteristics...
In order to overcome some ignored factors of traditional methods, a new method was applied for the research of driving cycles by the Markov stochastic process in the paper. The driving cycles were divided into 5 different states by maximum likelihood estimation. This associated driving segments with modal events which reflected acceleration variations and finely preserved speed variation characteristics...
