关于智能运输系统的关键理论——综合路段行程时间预测的研究

行程时间预测是智能运输系统研究的一个重要问题。为此,建立了许多算法,有历史趋势方法、非参数回归模型、时间序列方法、神经网络、卡尔曼滤波、交通模拟和动态交通分配模型等。然而,在变化的交通状况和任意时段的条件下,这些方法和模型都不能取得令人满意的预测结果。在总结这些已有的预测方法和模型的基础上,提出了一种综合模型。     

面向对象的桥梁CAD建模分析

在桥梁设计过程中,将大量复杂而繁琐的设计计算、图表查询等任务交给计算机去完成,是桥梁CAD系统要完成的主要工作之一。过去,这种CAD系统的开发均采用面向过程的建模方法,用这种方法所得到的程序提供的一个面向工程的桥梁设计计算程序,不仅可读性差,更致命的是条件稍做更改,程序便要做相当大的变动,且可扩充性及可维护性差。将20世纪90年代的设计方法——面向对象技术应用于这类系统之上,是桥梁CAD系统今后发展的方向之一。适应这一发展要求,进行桥梁CAD系统面向对象的建模方法研究具有重要的意义。     

Price effects of airlines frequent flyer programs: The case of the dominant firm in Chile

Frequent flyer programs create a switching cost for the consumer and allow firms to obtain rents, for example, by exploiting the principal agent problem existing between the employee who travel and purchases the ticket and the employer paying for that ticket. In Chile LAN is the dominant airline in domestic markets and the only one that has a frequent flyer program (FFP); it faces some competition from two small carriers. Using a unique dataset for Chile, collected by ourselves from airlines websites in 2011 and 2012, we estimate the impact of the dominant airline FFP. For this purpose, we compare for each route the fares between airlines and between weekday trips (that accumulate full miles and are mainly for business purposes) and weekend trips (that accumulate less than full miles and are mainly for leisure purposes). The results show that the differential premium LAN is able to charge for weekday trips due to the FFP is around 35%. Three particularities of the Chilean market help the econometric identification: there is only one hub for all airlines (the capital city of Santiago), there is no business class in domestic flights, and none of the airlines is a low-cost carrier.     

基于乘客寻路行为的城市轨道交通车站导向标识序化设置研究

为实现轨道交通车站内客流快速疏散,避免因乘客滞留造成站内乘客出行效率低以及大客流压力导致的安全隐患等问题,本文对目前国内导向标识的设置原则及功能进行描述,依托大数据等信息化技术分析行人寻路行为机理及出行特征与导向标识序化设置间的关系,研究导向标识的序化设置,依据行人在不同交通设施的步行速度及信息处理时间,并提出在站内停顿点数量较多的通道、楼梯口及闸机处设置导向标识的位置,进而对导向标识的设置进行人性化和合理化的优化设置,对轨道车站内停顿点位置进行导向标识的合理布设,以快速引导行人进行出行决策,减少停顿点数量。     

The influence of employer ridesharing programs on employee mode choice

Employer ridesharing programs and employee mode choice were analyzed using Southern California data. Problems in estimating the costs and benefits of employer ridesharing programs were identified. Surveyed firms used a wide variety of information to estimate employee mode split internally. Virtually all surveyed firms offered free or subsidized parking to some or all of their employees. Few responding firms estimated the cost of providing employee parking accurately, if at all. Despite these significant data limitations, factors influencing firm choice of employer ridesharing program components were identified. The influence of employer ridesharing programs on employee mode choice was modeled using weighted least squares logit regression analysis. Firm size was foung to be the single most important variable identified in the analysis. Larger firms were more likely to offer ridesharing incentives to their empolyees, and to report direct employer benefits from ridesharing. Alternative work hours hindered the formation of ridesharing arrangements in some cases. Relatively few firms promoted ridesharing on a purely voluntary basis. A private market for employer ridesharing services was found to exist, however. Personalized matching assistance may be a critical factor in developing more effective employer ridesharing programs. Parking pricing and supply control measures probably would have a larger impact on employee mode split overall. Parking management faces severe obstacles in implementation, some of which might be overcome through the more extensive provision of ridesharing services, such as personalized matching assistance. to employees at specific employment sites by their employers.
