Noise and air pollution monitoring for more efficient mobility
The Nice Côte d'Azur Metropolis supports the evolution of air pollution and noise pollution in certain areas and frequented axes of its territory. Companies are sometimes found concentrated in employment basins, while workers' homes are concentrated in cities like Nice or on the coast. For example, nearly 8000 commute to work in Carros, one of the main work centers of the Metropolis. 82% of these workers use their personal car; around 30% live in Nice and 50% live within a perimeter of less than 15 minutes by car to get to their work. The road serving Carros is totally congested with very high air and noise pollution markers. The Metropolis would thus be interested in improving the data in its possession, that is to say recovering the available data, consolidating, homogenizing and making this data interoperability in order to lead to improvement areas.
The goal would be to improve the quality of life of its inhabitants by reducing this pollution linked in particular to road traffic, and this, by offering alternatives (alternative roads, improvement of the public transport offer or alternative solutions). The data model that would be produced could be replicable on the scale of other territories due to its quality and standardization. This model could become the "standard data format" for the analysis of these noise and air pollution.
Data Sets description
The Nice Côte d'Azur Metropolis already has FIWARE data models and in partnership with the Mediterranean Institute for Environmental Risk and Sustainable Development (Université Côte d'Azur - IMREDD) have developed the TIP "Territory Information Platform". These data models will be usable within the framework of GreenMov, being available in Open Data or via the Université Côte d'Azur - IMREDD TIP. In order to improve this available data, Université Côte d'Azur - IMREDD, representing the Metropolis within the framework of the project, has the possibility of adding sensors in the Metropolis and crossing the data collected by these sensors with other data sources.
To date, the available data are at least the following: noise pollution (via the Auditorium of Nice Côte d'Azur), air pollution (via ATMOSUD), sunshine, wind speed by zone , rainfall, risks (flood, fire, land movements, seismic, avalanche and storm), land use density, places of residence (main and secondary residences), employment areas with their accessibility (in distance and time), congestion matrices (with road flows of personal cars and public transport), multimodal accessibility indices, etc. As part of the project, the consortium (Université Côte d'Azur - IMREDD - NCA) is considering the collection of unstructured data by applying Artificial Intelligence to extract and analyze image streams to generate specific metadata, to improve the analysis of traffic within a 15-minute perimeter by car from the Carros Industrial Zone.
European Data Portal relevance
In order to arrive at a standardized data model, a study of the data relevant to the project should be carried out. Thus, basic air and noise pollution data should be used. These can be crossed with road traffic, possible polluting points (factories, stadiums, etc.), public transport offers (stops, lines, timetables, stations), mobility offers (cycle paths, rental of bicycles, self-service, carpooling, etc…) the places of residence of the inhabitants, etc… Consideration will be given to the use of natural risk data. On the other hand, this standard data model must be usable by different route planners. Finally, in the event that sensors must be added in certain areas, support for the installation of the sensor and its positioning could be provided in order to obtain optimal data.
Required mobility services
By crossing pollution data, places of residence / work and mobility, improvement axis could be found at the Metropolitan level. Examples of application can be the calculation of better routes for traffic in the city (faster route with less pollution and noise) or better management of traffic around schools where parents drop off children at the front of the school. Interoperability is a goal to the territory ambition, and GreenMov will allow us to reach it. Bigger than our ambition, the methodology output of the project can support other regions to follow the same path.
