Questions
Question (1)
Dear Colleagues,
Let me invite you to publish the results of your scientific work in a special issue of the journal Sustainability (IF 2.576). The special issue is focused on Environmental Risk Assessment in Transport. A complete overview of the call for papers can be seen at: https://www.mdpi.com/journal/sustainability/special_issues/environmental_risk_assessment_transport
In this Special Issue, the focus will be on the current green transport policy—specifically, sustainable transport aimed at environmental protection that creates social balance and economic sustainability. The content of this Special Issue can be divided according to the types of transport (air, sea, ship, rail, road) or according to other subdivisions into individual and public, and passenger and freight. Intermodal approaches that contribute significantly to reducing the impact of transport on the environment are especially welcome. A key area of current research is the application of SMART solutions throughout the logistics chain, as well as the challenges of intelligent transport systems, which have grown in importance in the last twenty years. We expect a minimum of 20 articles from different European countries in this Special Issue.
