This study examined the history, current situation, and characteristics of mobility management (MM) in Japan and quantitatively analyzed the effectiveness of MM in Japan by extending a previous meta-analysis to include data until 2003. The most frequently used MM method...

Surveying the recent trend toward e-commerce and computerization in the trucking industry, this paper establishes a framework for analyzing the impact of information and communication technology on road freight transportation in terms of commerce, logistics and fleet ma...

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...
