European cities are facing major challenges related to high levels of traffic congestion. Current solutions to regulate traffic are mainly based on stable speed limits defined by the current regulation which came into force on 2 January 2021, and which will be enforced from July 2021. However, this model does not adapt to unforeseen circumstances such as adverse weather conditions, high levels of air pollution or mass events. The Barcelona City Council and the Municipal Institute of Information Technology (IMI) are participating in the European CELESTE project (dynamiC spEed Limits compliancE for optimiSed Traffic managEment) in order to provide the city's traffic managers with the means to establish and guarantee the basis for compliance with dynamic speed limits according to current and predicted situations.
CELESTE is a project funded by the European Institute of Innovation and Technology (EIT) of EIT Urban Mobility. The project will analyse the current synergies between dynamic speed limits and the ISA (Intelligent Speed Assistant), and will therefore look for both technological solutions, especially in terms of telecommunications, and evaluation tools to support traffic management in this regard. Functional prototypes will also be developed alongside cities to solve the challenge of dynamic speed limitation. The combined results will provide the necessary technological and organisational certainty for the adoption of dynamic speed limitation and the enforcement thereof.
