Solving traffic congestion in Mediterranean cities

REMEDIO is an international project focusing on high density areas surrounding the city centres in middle sized cities and towns in the Mediterranean region. The project is tackling the thorny issue of traffic congestion – how to reduce the impacts and the causes of this bane of modern urban life.

Cities and towns across the Mediterranean region typically include roads often suffering from traffic congestion. People living in these urban areas are subject to various negative impacts on their daily lives: noise, air pollution, traffic congestion, and poor availability of green spaces. Many of these problems are directly or indirectly linked to the need for mobility “imposed” or stimulated by city life, but in themselves they cause lower health outcomes, negative economic impacts and social exclusion.

The REMEDIO project provides three stages:

1) Territorial partners implement soft actions of low carbon mobility solutions (e.g. a bike sharing network in Split and Treviso; bicycle, pedestrian and parking areas in Loures; redesign of a major penetration axis with a second generation bus lane in Thessaloniki).

2) Scientific partners jointly implement an Integrated Modelling Tool (IMT), in order to assess the present and future scenarios road performance. This includes:

  • Traffic and freight transport modules based on the “Simulation of Urban Mobility” (SUMO) traffic model,
  • Pollutant emissions, Carbon footprint and Energy modules based on the “Passenger Car and Heavy Duty Emission Model (Light)” (PHEMLight) model,
  • Air dispersion module based on the ‘Pollutant dispersion in the atmosphere under variable wind conditions’ (VADIS) model,
  • Noise module based on the the “Common Noise Assessment Methods in Europe” (CNOSSOS-EU) methodology
  • Cost and Health modules based on statistical modeling to relate air pollution and meteorology to health events (deaths, hospitalization) and on the estimation of medical costs

IMT is used to simulate the pilot activities for low-carbon mobility solutions resulting in a set of scenarios representing present and future mobility and environmental settings.

3) The city communities are engaged in testing an operational path towards a participatory governance such as “horizontal condominiums” or “road contracts” that should lead to higher environmental and mobility performances.

Alongside these activities, there is an education programme led in Treviso, implemented in cooperation with the ISIDE network. This network of schools promotes energy saving and environmental awareness. Thanks to the REMEDIO project, 20 educational paths involving about 20 classes with 500 students for about 245 hours with 11 educators and teachers and 4 administrative officers were implemented over four months.

The REMEDIO consortium consists of eight partners: Regional Agency for Environment Protection in Veneto Region (Italy), Municipality of Treviso (Italy), Aristotle University of Thessaloniki (Greece), Instituto Superior Técnico (Portugal), University of Seville (Spain), Metropolitan Development Agency of Thessaloniki S.A. (Greece), City of Split (Croatia), and the Municipality of Loures (Portugal) from five different Mediterranean countries.
