Recent Research and Development on Advanced Technologies of High-Speed Railways in Japan

Summary This report outlines the rolling stock of “Shinkansen” and conventional “narrow-gauge” railways, and reviews the research and development to put railway vehicles into revenue service from the viewpoint of rolling stock dynamics in Japan.     

Evacuated tube transport technologies （ET3）^tm： a maximum value global transportation network for passengers and cargo

Evacuated Tube Transport Technologies(ET3) offers the potential for more than an order of magnitude improvement in transportation efficiency,speed,cost,and effectiveness.An ET3 network may be optimized to sustainably displace most global transportation by car,ship,truck,train,and jet aircraft.To do this,ET3 standards should adhere to certain key principals:maximum value through efficiency,reliability,and simplicity;equal consideration for passenger and cargo loads;optimum size;high speed/high frequency oper...     

A time series analysis of monthly ridership for an urban rail rapid transit line

This paper presents two time series regression models, one in linear form and the other in logarithmic form, to estimate the monthly ridership of a single urban rail rapid transit line. The model was calibrated for a time period of about six and a half years (from 1978–1984) based on ridership data provided by a transit authority, gasoline prices provided by a state energy department, and other data.The major findings from these models are: (1) seasonal variations of ridership are –6.26%, or –6.20% for the summer period, and 4.77%, or 4.62% for the October period; (2) ridership loss due to a station closure is 2.46% or 2.41%; and (3) elasticities of monthly ridership are –0.233 or –0.245 with respect to real fare, 0.113 or 0.112 with respect to real gasoline price, and 0.167 or 0.185 with respect to real bridge tolls for the competing automobile trips. Such route specific application results of this inexpensive approach provide significant implications for policymaking of individual programs in pricing, train operation, budgeting, system changes, etc., as they are in the case reported herein and would be in many other cities.     

基于模糊神经网络的桥梁诊断辅助系统研究

以桥梁的表观检测数据及无破损检测试验结果为依据,结合专家对系列桥梁的诊断评价结果,利用神经网络、模糊评判等信息处理技术开发了一套用于管理的桥梁诊断辅助系统。该系统可以帮助桥梁管理人员从大量的检测数据中,综合评价桥梁的老化状况。以现场检测得到的数据为例,详细地阐述了系统中桥梁老化评价功能的推理过程,并通过几座桥的检测实例验证了系统的可靠性。系统已在中国和日本的部分地区使用,提高了桥梁的管理工作效率。
