Organisational structures and functions in Bus Rapid Transit,and opportunities for private sector participation

Over the past two decades, Bus Rapid Transit (BRT) has become an established transportation technology, which delivers high quality, high capacity transit at much lower cost than rail-based modes. Although initially associated with South America, it is now global with a wide array of implementations in Asia, Africa, North America, Australia, and Europe.     

Development of a probabilistic model to optimize disseminated real‐time bus arrival information for pre‐trip passengers

In the advent of Advanced Traveler Information Systems (ATIS), the total wait time of passengers for buses may be reduced by disseminating real‐time bus arrival times for the next or series of buses to pre‐trip passengers through various media (e.g., internet, mobile phones, and personal digital assistants). A probabilistic model is desirable and developed in this study, while realistic distributions of bus and passenger arrivals are considered. The disseminated bus arrival time is optimized by minimizing the total wait time incurred by pre‐trip passengers, and its impact to the total wait time under both late and early bus arrival conditions is studied. Relations between the optimal disseminated bus arrival time and major model parameters, such as the mean and standard deviation of arrival times for buses and pre‐trip passengers, are investigated. Analytical results are presented based on Normal and Lognormal distributions of bus arrivals and Gumbel distribution of pre‐trip passenger arrivals at a designated stop. The developed methodology can be practically applied to any arrival distributions of buses and passengers.

客车空气压缩机皮带轮断裂失效分析

运用金相显微镜、扫描电镜和能谱仪等分析仪器，研究了某客车空气压缩机皮带轮断裂的原因。结果表明，该空气压缩机的皮带轮辐条与轮毂、轮盘连接处产生应力集中现象，是导致该处出现裂纹并发生疲劳断裂的主要原因。针对以上问题提出了改进建议。

A journey from adversary to partnership bus reform in NSW

This paper continues to debate the importance of understanding in the NSW Bus reform process of the relationship between central agencies, service providers, the academic community, key consultants and contractors within the setting of the transport service organisation framework. Sydney is a modern city with heavy rail, light-rail, monorail and an extensive Harbour, with bus services owned by Government as well as private interests. The paper addresses the case for reforms, the approach taken, competition policy, the subsequent development of partnerships, performance of the regulator, passenger benefits, growth and the differences between Metropolitan/Outer Metropolitan and Regional and Rural bus services.
