FOREVER (2013 - 2014): Future OpeRational impacts of Electric Vehicles on national European Roads (CEDR Call 2012, Noise)

With changing public attitudes regarding sustainability and energy efficiency, the use of electric vehicles (either hybrid electric or fully electric) on European road networks is increasing. While the main focus of noise-related research has been associated the use of these vehicles in low-speed urban environments, particularly in relation to the safety risks posed to vulnerable road users, little research has been carried out to date on the potential noise impacts of electric vehicles on roads, which fall under the jurisdiction of National Road Administrations (NRAs), namely motorways and other primary routes. As part of research funded under the CEDR Transnational Road Research Program Call 2012 on Noise, the FOREVER project aims to address the issues on NRA roads by providing data and information focusing on three issues: (1) the identification of the noise emission levels from electric vehicles (powertrain and rolling noise components) at speeds representative of NRA roads, including the impacts of added alert sounds and the development of input data for the CNOSSOS-EU noise model, (2) the noise emission from low-noise tires and tires used with electric vehicles, and (3) an estimation of the noise impacts of electric vehicles and low-noise tires on NRA roads, based on different fleet compositions and different take-up rates of electric vehicles.

This project is funded under the CEDR Transnational Research Programme, Call 2012 “Noise – Integrating strategic noise management into the operation and maintenance of national road networks"”. For more information see the project webpage: http://forever.fehrl.org/
