In Paris and other cities, street lights stay on at night even though they could be dimmed when there are fewer people about (to reduce their carbon footprints and light pollution) or brightened for specific events (e.g. around stadiums on match nights). This intelligent street lighting system in particular needs to cater to soft transport (walking, cycling, etc.).
One approach could involve fitting sensors and meters on street lights but trials so far have shown that these systems require heavy investment and furnish comparatively unreliable results. This challenge will consider other approaches, such as using geo-statistics from a mobile operator.
How to provide intelligent lighting in the streets of Paris by analysing urban travel data.
The existing maps showing activity on the streets of Paris at night are only based on noise produced by motor vehicles, whereas light grading also needs to accommodate soft transport (walking and cycling, principally).
The experiment field covers a selection of Parisian neighbourhoods and other places such as the area skirting Jean Bouin stadium, the esplanade in front of Notre Dame cathedral, and Place de la Nation. In these neighbourhoods, the goal will be to plot out time-based lighting grading scenarios catering to different points in a same group of streets, using the analysis of urban travel data. This map’s scenarios will for example need to encompass variations on a weekly and seasonal basis, as well as one-off events (White Night festivals, etc.).
This challenge will interest any company that operates urban infrastructure – such as EDF (France’s legacy electricity utility) or Bouygues Energies & Services (which manages and maintains street lights in Paris via its subsidiary Evesa) – and wants to sharpen its competitive edge by providing a wider choice of urban services and connected objects including upgradable dynamic lighting.
Cities such as Paris are broaching these issues to reduce light pollution and power consumption. This challenge should provide the city with a new night-time map including soft transport.
SFR is keen on a solution to manage street furniture in general, and street lighting in particular, that taps into the geo-statistics expertise it has developed by using radio-mobile data.
BYES (BOUYGUES ENERGIES & SERVICES) / EVESA
BYES (BOUYGUES ENERGIES & SERVICES) / EVESA will supply georeferenced data pertaining to street lighting facilities in the experiment area. The selection will be representative of Parisian streets and sights
SFR will provide travel-related data from mobile devices (technical data from GSM antennas) for a representative sample (approx. 30% of the population), covering uninterrupted periods (24/7) in France (locals and foreigners)
