According to the mid-term review of the EU White Paper on Transport, short sea shipping is expected to grow at a rate of 59% in metric tonnes, from 2000 to 2020. If we consider that the overall expected growth in freight exchanges is of some 50%, sea transport is one of the most feasible ways to reduce traffic congestion on European roads. High speed vessels are a possible way to compete with road transport on certain routes; however, these ships are highly affected by heavy weather. This paper analyses the weather influence on several short sea shipping routes to be served by fast ships.

The article describes the existing problems of uncertainty in the system of operational redistribution of traffic flows, considers stochastic factors that are different in nature and features of the effect on the transport system, which require consideration in the operational management of traffic flows, as well as the features of their influence on the short-term state of the transport system. A simplified classification of stochastic factors is given, algorithms for the connection of these factors with each other and with indicators that are already taken into account by the management system are given, the nature of the influence is indicated. Statistical data samples are analyzed and the basics of methods for working with them are indicated. For the most common stochastic factors, such as the number of traffic accidents on city road networks and weather and climatic features of the region, methods for generating graphic materials and mathematical approximations are proposed, and formulas for calculating some random variables are recommended, including using limits in the framework of the phase theory of traffic flows. Cartograms with the help of which it is possible to establish stochastic dependences of climatic changes and changes in the ecological state by the example of Mariupol are given. It is proposed for practical use a detailed block diagram of identifying stochastic factors, the formation of information arrays, their analysis and the supply of control signals to the operational management system. The diagram shows a clear differentiation of the primary and secondary stochastic data arrays, and their recommended links to the operational process control system of the transport process are indicated. Using the stated theoretical foundations, it becomes possible to increase the efficiency of the city’s transport system by optimizing the processes of the operational redistribution of traffic flows on the road network and making changes to short-term planning processes. Keywords: stochastic factors, road transport, traffic flow, transport system, transport planning, management, regulation.

Purpose – The purpose of this paper is to analyse the economic benefits of short sea shipping (SSS) in the shape of Motorways of the Sea (MoS) compared to road transport. The study cover a gap in agro-food economics and analyses the economic benefits of sea transport mode compared to road transport in the food trade between Spain and Italy for a specific product: olive oils. Design/methodology/approach – Three different transportation scenarios are considered (road only, road combined with accompanied SSS and road combined with unaccompanied SSS) linking the main olive oil production and consumption areas in Spain and Italy. In each scenario the cost per unit shipped have been calculated. Findings – The results show the road option is about 30 and 34 per cent more costly than the best SSS option available for the exportations from Jaén and Southern Catalonia, respectively. Research limitations/implications – The need of further research is identified, mainly focused in two directions: first, the need for inclusion of new variables to the model (e.g. value of time, seasonality, complexity of the transport chain, potential demand, etc.) to better assess the competitiveness of the sea connection and, second, a study of the environmental impact and socio-economic benefits of SSS implementation for the agri-food sector. Originality/value – The research enriches the current literature on this field and provides a basis for future studies. In particular, it corroborates the strategic decisions taken in the framework of European transport policy demonstrating a greater economic sustainability of SSS, and more specifically MoS, compared to the road transport.

Recent claims about the potential of UK land to support significant biofuels production for transport are bold, if not surprising. British renewable energy policy appears to be focussed on electricity production, at the expense of the heat and transport sectors. However there are environmental and strategic reasons for reducing the carbon intensity of UK road transport. This paper reviews past and recent studies of the feasibility of liquid biofuels production in Britain. Many earlier studies may have underestimated this potential, and the policy context has shifted significantly, but it would still be difficult to meet current UK gasoline needs from arable and set-aside land. In conclusion, a realistic short-term goal may be 2–3% of UK transport fuel needs from domestic resources by 2010.

Field studies on traffic noise-induced annoyance have predominantly used estimated outside noise levels. We intended to complement existing knowledge with exposure–response relationships that are based on precise indoor noise measurements. Acoustic recordings inside the bedrooms of nightly road traffic and annoyance ratings in the following morning were obtained from 40 suburban residents (mean age 29.1 years ± 11.7; 26 females). We derived exposure–response functions for the probability to be “annoyed at least a little” (%LA). Further analyses compared data from the current study with those from two earlier studies on railway and aircraft noise. Annoyance increased with the number of traffic events and the equivalent sound pressure level. The inclusion of non-acoustical factors (such as assessment of road transport) improved the prediction considerably. When comparing the different traffic noise sources, %LA was higher for road than for air traffic at a given LAeq,night, but higher for road and railway than for air traffic at a given number of noise events. Acoustical as well as non-acoustical factors impact short-term annoyance induced by road, railway, and air traffic. Annoyance varies across noise sources, which may be due to differences in acoustical characteristics or in the temporal noise distribution throughout the night.

This paper assesses the role that both vehicle emissions and fuel standards can play in moderating the projected increase in emission of pollutants from the road transport sector of Association of Southeast Asian Nations (ASEAN) member countries by adopting international best practice as it currently stands. It concludes that much could be done within ASEAN to align with international best practice in terms of vehicle emission regulations in the transport sector. In addition, exploring alternative fuels such as natural gas, ethanol, and biodiesel could also offer substantial benefits in reducing air pollutants and emissions in the short term as member countries develop their refining capabilities to produce ultra-low sulphur fuel. Until then, it is likely that vehicle emission regulations may be held back at the Euro III (3) level. Despite that limitation, improving existing motorcycle emission regulations could provide abatement possibilities, while also improving local ambient conditions. Recognizing that international best practice is limited for motorcycle emission regulations, ASEAN member countries could play a key role in drafting and possibly shaping such emission standards.
