现代有轨电车最小发车间隔及相关指标研究

最小发车间隔是确定现代有轨电车开行密度和运输能力的参数。现代有轨电车作为一种新型的中低运量的地面快速轨道交通系统,其最小发车间隔的确定与地铁、BRT(快速公交)等其他交通方式均有所差异。通过对道路交叉口、列车停站、列车折返及区间长度等影响因素分析,研究了现代有轨电车最小合理发车间隔,并对其运输能力与车辆配属进行了探讨,为现代有轨电车规划建设提供决策参考。

智能交通(以下可简称ITS)产业在我国是正在成长的幼稚产业，且具有跨地 区、跨行业、跨部门的复合产业的性质.针对这一产业特征，创建并设计智能产业化基地建设模式，不能照搬照抄现有科技园区的范本；在借鉴已有园区模式的基础上，必须结合ITS产业的特点和我国ITS产业的现状，进行制度创新和理论创新.因此，如何研究设计“小基地、多功能、强辐射”的墓地运作模式，探索出一条投入少、效益高、带动面宽、运作灵活的园区建设的道路，必须学习和借鉴有关产业集群理论和产业化基地理论，这不仅可以丰富高新技术科技园区建设的理论和实践，而且对指导创建我国智能交通产业化基地具有重要的现实意义.

Reflections on energy issues in China

Energy, which has a bearing on both economic and national security, is of importance and a major constraining factor to the economic and social development of China. The article analyses the current worldenergy status and development trend from the perspectives of resources, production and consumption and in thecontext of its implications on the environment and economic and social development, and explores opportunitiesand challenges for China's energy development. With a focus on the strategy of energy development in China,the author proposes a new energy development approach with Chinese characteristics whose main elementsare: energy-saving, high-efficiency, diversified development, environment protection, technology guidance andinternational cooperation. In other words, China is striving to build a reliable energy production, circulationand consumption system that is efficient, technologically advanced, low polluting and ecologically friendly. Along-term development strategy with priority on energy conservation, efficient utilization of primary energyand advanced electricity system is expounded in the paper. The author also describes the prospect of energytechnology development and stresses the implementation of energy strategy by further improving energy policyand related mechanisms, strengthening macro-management and the essential role of the market in resourceallocation so as to ensure the economic and social development of China through reliable energy supply.     

The cumulative effect of nuisances from road transportation in residential sectors on the Island of Montreal – Identification of the most exposed groups and areas

Air pollution and road traffic noise are considered to be the two most important nuisances that could negatively affect the quality of life. A prolonged exposure to high concentrations of these pollutants could conduct to various health problems. Studies in environmental equity have often considered these nuisances individually whenever it comes from the same source. The main objective of this paper is to determine if the 15 years of age, those aged 65 and over, visible minorities and low income individuals located in a portion of the Island of Montreal are overrepresented in city blocks characterized by having among the highest levels of transportation-related air pollutants (i.e., ambient concentrations of NO₂ and road traffic noise in decibels (dB(A)). The results show that low-income individuals and, to a lesser extent, visible minorities, are significantly overrepresented in city blocks characterized by the higher levels of NO₂ and road traffic noise in dB(A). Multinomial logistic regression analysis confirms these results, and also shows that young people under 15 years are under-represented in the most polluted areas. However, contrary to the previous bivariate results, people aged 65 and over are negatively and significantly associated with the likelihood of their living in a city block located in an advantaged area after controlling for the independent effects of the other explanatory variables. Moreover, visible minorities are significantly overrepresented in advantaged areas. Considering the observed results, some solutions are identified to reduce road traffic noise and air pollution in the city blocks localized near major traffic arteries.
