The process of hydraulic fracturing for recovery of oil and natural gas uses large amounts of fresh water and produces a comparable amount of wastewater, much of which is typically transported by truck. Truck transport of water is an expensive and energy-intensive process with significant external costs including roads damages, and pollution. The integrated development plan (IDP) is the industr...
Extended abstract 1- Introduction Forest is a sustainable ecosystem with a high balance, and is characterized by non-eroded soils and sediment-free water. Forest roads serve as the largest construction activities and a component added to the forests which are required for the accessibility to forests and forest resources, logging, transportation, conservation, tourism, etc. However, these...
Redesigning of the traffic system on highways, streets and avenues is quite important, when aspects such as network plan, geometric design, traffic control, operation, regulation and enforcement of roads are considered as a unified system. The ‘highways’, which should primarily consider transport function for intercity connections, and ‘streets and avenues’, which should also involve the variou...
Emerging countries currently have the highest growth rates in transport energy consumption and straightforward greenhouse gas emissions. In recent years many policy approaches in EU countries have been implemented to cope with problems in transport sector. The core objective of this paper is to derive lessons learned from different EU policies for road passenger transport which can also be impl...
This study set out to establish that land transport system in the country of destination, determines the turn-around time, capacity utilisation of port infrastructure, facilities and cargo-handling equipment and general port performance. Of particular interest, is the contribution of road transport infrastructures and system to the magnitude of turn-around time, port performance and general eco...
People with disabilities have the same fundamental right to access mainstream services in the community (education, health-care, employment, social services and social protection) as any other citizen. Inclusive transport is a critical element in a comprehensive strategy of mainstreaming people with disabilities in developing countries. A freely accessible society without any physical obstacles...
There is a strong imbalance in EU transport mode share. In addition issues like road congestion, noise, accident rate and especially pollutant emissions result not only in external costs to society but also in high logistical costs to customers of transport services. The present paper proposes an assessment model to evaluate final internal and external costs of transport chains served by road a...
One of the major obstacles in the process of national development, is the disruption in regional balance construct. As has been noted in some studies the existence of regional inequity leads to domination of some regions to surrounding regions and causing political and economic challenges in developing countries. And given that transportation is one of the components of region, undoubtedly equi...
One important step to achieve a sustainable transportation system is to control the impact and evaluate the effect of various influencing factors toward three dimensions of sustainability. Within this context, diverse analytical approaches have been developed to assess the sustainability level of various transportation systems, however, sustainability evaluation based on fuzzy multiple criteria...
AIM The changes of the hypothalamic pituitary adrenal (HPA) axis response to a long distance transportation results in increase of adrenocorticotropic hormone (ACTH) and cortisol levels. The purpose of the study was to quantify the level of short-term road transport stress on circulating ACTH and cortisol concentrations, related to the effect of previous handling and transport experience of hor...
