Results of a recent study indicate that intelligent transport systems (ITS) applications such as eco-driving support and eco-driving coaching have potential to reduce energy consumption and CO2 emissions by about 3-11% on European roads. Dynamic traffic management systems have also been found to be effective tools in reducing emissions and congestion. Hard shoulder running has been estimated to reduce travel times up to 26% in certain conditions and locations and energy consumption and CO2 emissions by 4%. Ramp metering was also found to reduce average travel times by 4-35% in the sites evaluated.

The results are based on a literature study and expert assessments carried out in 2012. The analyses were carried out for iMobility priority applications which are expected to offer most potential to improve safety, reduce congestion, and reduce energy consumption and CO2 emissions. The priority applications and their most likely impacts in Europe have been documented in the iMobility Implementation Road Map published by the Implementation Road Maps Working Group of the iMobility Forum.

iMobility Forum is a group of European private and public ITS stakeholders. The iMobility Forum succeeds the eSafety Forum. Its field of work includes ICT systems for resource-efficient and clean mobility in addition to the latter’s focus on ICT-based safety technologies. The iMobility Forum is a joint platform open for all road stakeholders interested in ICT-based systems and services.
