The popularity of modern water bikes increases due to the relatively high speed developed with the use of a human muscle power only. For example, the maximum speed of prototypes reaches the value 3 m/s. Similar vehicles can be used not only for recreation and fitness, but also for transportation. To increase their speed and tonnage, we recommend improving the pontoon shape and using electrical power. The underwater part of the pontoon shape was recommended to be similar to the body shape of the fastest fish in order to decrease the wave resistance and total drag. The optimal depth of the movement of corresponding shapes was calculated. The total drag and maximum speeds of the vehicles with the human muscle and electrical power are estimated. Expected success in improving the pontoon shape opens wide prospects for the use of these special-shaped hulls in shipbuilding.

Abstract The Green Corridor concept represents a cornerstone in the development and implementation of integrated and sustainable transport solutions based on trans-nationality, multi-modality and a high involvement of public and private stakeholders, including the political level. Despite the fact that the Green Transport Corridor (GTC) concept is founded on the three dimensions of sustainability with a strong emphasis on environmental aspects, the corridor hubs as well as the whole transport corridors have to find ways to handle and transport dangerous goods by keeping the high sustainability standards. The paper addresses the research questions what kind of economical, ecological and social risks might occur in the context of handling and transportation of dangerous goods in a Green Transport Corridor in the Baltic Sea Region, what consequences they might have on the GTC design and how and with which measures they can be managed. Based on this analysis the development of a comprehensive risk management concept for the handling and transportation of dangerous goods in Green Transport Corridors in the Baltic Sea Region based on Schröder and Prause (2015) will be started. The concept will include practical implications and best practices.

The objective of green logistics has thus far failed. For example, the share of greenhouse gas emissions by the transportation and logistics sector in Europe rose from 16.6% in 1990 to 24.3% in 2012. This article analyzes the reasons behind this failure by drawing on political, economic and business as well as social motivations and examples. At the core of this analysis are the established theorems of the Jevons paradox and the median voter (Black, Downs) in combination with time-distorted preferences of voters and consumers. Adding to the hurdles of green logistics are the problems of short-term political programs and decisions versus long-term business investments in transportation and logistics. Two cases from Germany are outlined regarding this political “meddling through” with a recent 2015 truck toll decision and the support for electric trucks and vehicles. Finally, the article proposes two ways forward: public control and restriction of carbon raw materials (coal, oil), as well as public investment in low-emission transport infrastructure or biofuels as the more feasible and likely alternative.

Abstract The green transport corridor concept represents a cornerstone in the development of integrated and sustainable transport solutions. Important properties of green corridors are their transnational character and their high involvement of large numbers of public and private stakeholders, including political level, requiring sophisticated approaches for implementation, management and governance. The current scientific discussion focusses on Key Performance Indicators (KPI) for monitoring and management of green transport corridor performance emphasizing the operational aspects. The green corridor balanced scorecard approach tried to mitigate the strategic weakness of KPI concept by integrating cooperative and long-term views in order to come closer to a comprehensive green corridor control system. Until now all discussed KPI sets are too small and narrow for a successful implementation of green corridors so there is a need for the development of an user-oriented model for green corridor control systems based on building blocks integrating existing KPI sets. The building block approach for implementation has been successfully used for implementation and simulation in supply chain management. Based on these results the paper will present a holistic control system for successful implementation of green transport corridors based on building blocks integrating recent results about KPIs and balanced scorecards approaches. The research will empirically be verified by empirical results from European green corridor projects.
