Lack of space for station plazas is one of the most common public transportation problems. Especially, most of the severe congestion problems occur due to concentration of taxies, buses, and private cars in station plazas. Improving the congestion at these station plazas by site development and traffic management is important for better public transportation environment. This paper, analyzes existing situation and issues of operation for station plazas in Tokyo metropolitan area by questionnaire survey. Finally, future directions of management of station plazas are discussed.
Noting that the CO2 emission from international shipping accounts for 3% of the world and continues to increase, global regulatory framework has been under discussion at International Maritime Organisation. This paper analyses regulatory system design to utilise large abatement potential of shipping, in particular, how to set mandatory standards for efficiency of individual ships. As regards Market-Based Measures, this paper argues the merits of leveraged incentive scheme, as a variation of fuel levy, and the necessity of sector-specific target setting based on the efficiency improvement.
In Thailand, transport sector is the largest energy consuming sector (38%). Road haulage of freight transport accounts for approximately 92% of total domestic freight movements. Accordingly, it is one of the largest contributors to adverse environmental impacts. This study presents one option to reduce energy consumption through modal shift from trailer to intermodal transport involving railway and waterway. It focuses on freight movements between Bangkok and Hat Yai in Thailand. Energy savings are measured by multi-objective optimization model using decision variables consisting of three mode options: trailer only, intermodal-rail and intermodal-waterway. In addition to energy consumption, the objective function also includes time and charge of shipment factor.
The total volume of international air cargo from/to Japan has been decreasing after 2004. The purposes of this paper are to investigate the characteristics of recent air cargo by “Foreign Trade Statistics” and to develop modal split model between marine and air transport. We clarified that one of the decline’s reasons was based on the decreasing import goods. The developed modal split model calibrates logistics cost which involves time, cost, inventory cost and obsolescence cost. We applied the model to several international OD pairs, and it was verified that the model has sufficient applicability.
