Smart vs conventional motorways: environmental impact assessment under realistic traffic conditions
2020
Abstract This research aims at assessing the environmental impacts exerted by a smart motorway compared to those of a traditional motorway. The study has global policy implications: it takes into account the impacts due to the construction and maintenance of the infrastructure and the environmental effects produced by the traffic emissions, taking into account smart technologies and truck platooning regulation. Through a classical LCA approach, 1 km-long smart motorway with 2 m-high embankment was assumed as the functional unit for the analysis. A realistic traffic condition has been considered. A comparison between environmental effects produced by the use of virgin material and by Reclaim…
Mobile Mapping System: case study of the Messina-Palermo motorway layout
2009
This paper presents the first results of the MMS (Mobile Mapping System) survey on the geometry of the A20 italian motorway Messina-Palermo. The layout parameters are the essential data for an effective management of a single or a road network. In particular these parameters are essential for applying the Design Consistency methodology to proposed or existing road infrastructures; through this methodology the road manager can make sure that the road characteristics are adjusted to the driving behaviour of motorists by analysing the relationship between horizontal and vertical alignment and the design and operating speed. Both the difficult finding of the road design schemes, particularly in…
Natural assets in the right-of-way of A-4 Motorway in the Góra Świętej Anny Landscape Park, Opole Region
2014
Construction of the A-4 Motorway section in the Opole Region begun in Summer 1997. Very soon vigorous resistance of ecological NGOs was encountered. The bone of contention was the section of motorway that passes through the Góra Świętej Anny Landscape Park and verges the natural reserve of strict protection Ligota Dolna where rare species of thermophilic plants are sheltered. Between 2011 and 2013 a detailed mycological, geobotanical, floristic and fauna research took place within the right-of-way of the A-4 Motorway section crossing the Góra Świętej Anny Landscape Park in the Opole Region. The survey revealed several rare and protected species of fungi, plants and animals along the road, i…
Evaluating the safety of platooned heavy vehicles: A case study
2016
In the right lane of motorways with trucks' overtaking prohibition is very common the formation of platoons of heavy vehicles. Although this traffic controls strategies can increase the capacity of passing lane, in the right lane may occur increases of rear-end collisions. The purpose of this research was to evaluate the safety of the platooned heavy vehicles by means a closed-form stream model. The case study of the Italian motorway A22 was examined. The sampling of platoons was performed in four observation sections.In the research have been investigated platoons with 2/20 heavy vehicles for each platoon. Many traffic parameters have been evaluated: frequencies of the number of platoons, …
Autoroutes et dynamique du tourisme
2006
The widening of the motorway network in France, during the nineties, gives the opportunity to analyze the relationships between accessibility and tourism. The A 39 skirts the foothills of the Jura and improve its accessibility although it does not penetrate into the mountains. From this example, we wished to evaluate the impact of such an infrastructure on the tourism activity in the Jura. The adopted method involves following the development of tourism starting from multiple sources provided by national statistics, traffic surveys carried out before and after the opening of the A 39, and the interviews of the people in charge for tourism in the Jura. The interest of these investigations is…
Starzec wąskolistny Senecio inaequidens D.C. w pasie autostrady koło Brzegu na Śląsku Opolskim
2018
The paper presents the vegetation types with invasive Senecio inaequidens along the road verges in the Opole Silesia. The large population of this South-African species was located in the second half of June 2018 in the green belt (central reservation) along the A4 motorway (motorway section Brzeg – Opole).
Nowe stanowiska interesujących halofitów wzdłuż autostrady A-4 na Śląsku Opolskim
2018
The paper presents new sites of interesting synanthropic plants in the Opole Silesia. Three halophilous species,Plantago coronopus L. Spergularia marina (L.) Besser and Cochlearia officinalis L. were found on road verges of motorway A4 within the section Brzeg – Prądy. All species were observed with very large population sizes. They can thrive because of de-icing of the motorway surface with the application of sodium chloride spray.
Competitiveness of short sea shipping: the case of olive oil industry
2016
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. …
Limits and perspectives of sea shipping of agro-food products in the Mediterranean basin. The role of Sicily
2011
In the process of the Euro-Mediterranean integration , and in prospect of the realization of the free trade area (FTA), motorways of the sea are one of the most ambitious initiatives. The agro food sector is worrying us in order to realize the free trade area. It offers many opportunities for the strong complementarity among the coastal countries’agriculture, that could see the countries of the Southern and Northern work together in a spirit of complementarity and cooperation. Sicily, in the middle of Mediterranean basin, is only marginally concerned by the agro food trade and by direct maritime trade between the two sides, due to the inadequacy of port logistics infrastructures. These, wit…
An stated preference analysis of Spanish freight forwarders modal choice on the south-west Europe Motorway of the Sea
2011
Abstract This paper aims to contribute towards the design of effective freight transport policy by means of empirical analysis. In order to do so, a stated preference survey is undertaken to model the modal choice between door-to-door road transport and short sea shipping in the Motorway of the Sea of south-west Europe. The proposed analysis will provide policymakers with the necessary tool to identify the critical areas that should be addressed by future policy action in order to boost short sea shipping on Spain's Mediterranean coast. By applying the proposed method, we will be able to obtain estimates of the subjective values of transport attributes – value of time, value of reliability …
