As part of the Mobility in Transition initiative, IDDRI, in collaboration with C-Ways, has developed a data science-based tool to support local authorities in implementing low-emission mobility zones, in their discussions and consultations with stakeholders to enable informed decision-making and greater certainty in terms of expected impact. This methodological approach has been tested in two cities, Strasbourg and Lyon, to demonstrate the tool’s potential.
The tool developed by IDDRI in collaboration with C-Ways consultancy is principally based on the use of the SIV (Système d’Immatriculation des Véhicules – French Vehicle Registration System) database (of which C-Ways owns the operating licence), in addition to INSEE surveys and analyses by SDES (Statistical Data and Studies Department of the Ministry of Ecological Transition).
The proposed approach aims to:
Facilitate dialogue and consultation between local authorities and stakeholders by providing an objective description of requirements and limitations that are specific to different trades and types of businesses;
Differentiate, target, scale or condition support proposals (economic, technical, transformational…) according to business categories or fleet size;
Evaluate the impact of measures taken from an economic, social and environmental perspective, justifying temporary or definitive exemptions if necessary by estimating the anticipated effects on air quality;
Monitor and compare the implementationschedule with the fleet renewal rate.
The ultimate objective is to inform and justify public authority decision-making.
