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.
