Abstract:

With the rapid increase of automobile ownership, Beijing, China is now facing serious challenging issues in regards to traffic congestion and vehicle emissions. On the list of alternative solutions to these issues, it is widely recognized that developing and improving public transportation systems is one of the most feasible and promising strategies due to its high passenger carrying capacity and low pollution on per passenger basis. To implement any viable public transit strategies, a comprehensive evaluation is always necessary, and a crucial component of this evaluation process is to accurately assess emissions and fuel consumption incurred by transit vehicles, which requires the use of driving cycles as the essential element. This paper is intended to develop city-specific driving cycles for transit buses for Beijing. The operational data of 126 buses are collected by using the portable global positioning system for three types of transit lines--bus rapid transit (BRT) line, express line, and regular line. By analyzing the operating characteristics, a methodology for developing driving cycles is proposed based on the parameter of vehicle specific power (VSP) distribution. Then, by applying this methodology, driving cycles for BRT, express, and regular lines are developed accordingly. Finally, the developed driving cycles are evaluated. It is shown from the analysis that the proposed driving cycles are able to reflect the real-world operating characteristics of transit buses better than other driving cycles. Further, the emission factors generated based on the developed driving cycles are found to be 5% lower in average than those predicted by using the default driving cycles in MOVES.
