车载控制器和列车管理系统接口监测系统设计

部分城市地铁车载设备由车载控制器（CC）和列车管理系统（TMS）组成.由于TMS常常显示CC通信状态误报警信息,给设备维护带来麻烦,容易延误设备维修时机.为此,提出一种监测地铁CC和TMS通信的监测系统,能实时监测并记录CC和TMS之间的通信信息,并且能够离线图形化解析监测数据,方便设备维护人员找出问题原因.该系统目前已成功应用,并取得了很好的效果.

基于操纵稳定性的某客车空气悬架系统结构改进

针对某空气悬架客车在行驶转向时车身侧倾角过大问题,提出在后空气悬架导向臂尾端添加车身侧倾稳定板的改进方案。对改进前、后空气悬架系统进行了KC分析,结果显示改进后的悬架系统侧倾刚度得到了有效提高。基于刚柔耦合建模方法,建立了改进前、后整车多体动力学模型。仿真结果显示改进后车辆稳态回转时车身侧倾角明显减小,不足转向度也有所改善;整车试验结果验证了仿真结果的正确性和改进方案的可行性。     

不同工作负荷下驾驶员的心生理特征研究

使用动态心电仪作为心生理检测仪器,综合检测驾驶员在不同道路交通环境条件下的心生理反应特征。试验结果表明,驾驶员在不同的道路交通环境条件下具有驾驶工作的心生理负荷特征,不同的驾驶行为和道路交通环境条件对驾驶员造成的心生理驾驶工作负荷不同,这为“人性化”道路交通安全研究提供了理论与实践依据。

Planning,operation, and control of bus transport systems: A literature review

The efficiency of a transport system depends on several elements, such as available technology, governmental policies, the planning process, and control strategies. Indeed, the interaction between these elements is quite complex, leading to intractable decision making problems. The planning process and real-time control strategies have been widely studied in recent years, and there are several practical implementations with promising results. In this paper, we review the literature on Transit Network Planning problems and real-time control strategies suitable to bus transport systems. Our goal is to present a comprehensive review, emphasizing recent studies as well as works not addressed in previous reviews.     

锯齿形过饱和公交优先信号交叉口进口道延误研究

公交优先是缓解城市交通问题的一种有效方法,故提出在过饱和信号交叉口进口道处设置成锯齿形,并设置车道预信号灯。本文基于定数理论的背景和信号交叉口延误理论,在已有延误研究的基础上,对过饱和信号交叉口进口道延误进行分析,推导出相应的进口道延误公式,通过对公交优先方隶实施前后的交通效益评价对比,证明该方案是有效且可行的。     

基于CATIA的公交车骨架建模方法

公交车骨架建模目前尚没有统一的建模方法,建模工具品种繁多,多根据工程师的经验及个人喜好进行建模。CATIA软件具有强大的三维建模能力和智能化的树结构,在车身设计中得到越来越广泛的应用。在CATIA建模过程中,建模方法对于提高建模效率,确保建模的准确性和后期修改的方便性至关重要。本文介绍了基于CATIA的公交车骨架建模方法及快速建模技巧,得到了较高质量的几何模型,模型可修改性较强,建模效率高,为公交车骨架CATIA快速建模提供了方法参考。     

Commercial public bus transport services in Germany: How a market in motion struggles with its regulatory framework

After decades of stagnation, the competitive market for commercial public bus transport services in Germany is beginning to move. Nevertheless, compared to the total market volume, the number of cases where competition is observable remains small. An empirical analysis of competition in the commercial services market as compared to competition in the non-commercial services market confirms that entry barriers do exist. These barriers clearly impede competitive developments in this embryonic market, which relies on the market initiatives of operators to develop. The paper identifies a key entry barrier in the institutional framework: for potential market entrants, the overall uncertainty regarding competitive procedures for commercial services is significantly higher than usual in tendering procedures. This high uncertainty poses the main disadvantage for newcomers as compared to incumbents.
