At present, the conventional way to sequence aircraft in the terminal area is to follow the first-come, first-served rule. Even though such sequencing is considered fair to all airlines and is associated with no increase in the workload of air traffic controllers, it is...

Abstract The objective of this paper is to develop a refined gravity model for the quantitative assessment of competitive hub status of cities between 2000 and 2012 from the perspective of international air traffic movements. Its focus of attention is Europe and Asia, w...

This paper examines international air passenger and cargo flows within and among Asia, Europe, and America, and the degree of air traffic density for major cities worldwide, using a basic gravity model composed of GDP, population, distance, and several dummy variables. ...

An algorithm is proposed for digital-to-analog conversion. The conversion starts with the most significant bit. This algorithm can be implemented using unity-gain buffers and thus permits high-speed data conversion. Switched-capacitor D/A and A/D converter architectures...

In northern countries, we sometimes encounterheavy snow fall and it causes low visible condition. In thiscircumstance, we have difficulty to keep the driving lane.For the purpose of safety driving, we develop the vehiclenavigation system with Ultra High Frequency (UHF) ...

In recent years, to cope with low carbon society and diversification of individual mobility, new kinds of vehicles have received a lot of attention to expand our mobility. This paper proposes a new concept of vehicle named portable personal vehicle. The proposed portabl...

To realize environmentally sustainable transport (EST), it becomes more and more important to reduce the environmental load from the transport sector while maintaining the level of mobility. Because mobility policies often conflict with environmental ones, policy decisi...

This paper examines international air traffic flows from, to and within East and Southeast Asia, and in turn the hub status of cities over the years from 1982 to 2012. Its focus of attention is the effects of new international airports and integrator's hubs on the mobil...

Probe vehicles provide some of the most useful data for road traffic monitoring because they can acquire wide-ranging and spatiotemporally detailed information at a relatively low cost compared with traditional fixed-point observation. However, current GPS-equipped prob...
