The Smart City Campaign's Goals

Address Public Concerns around Poor Air Quality

Parisians were becoming increasingly concerned about air pollution resulting from heavy vehicle traffic in historical public squares. Air and climate pollution topped public concerns for 4 years in a row in annual Commission for Sustainable Development surveys.

Create Clean Public Spaces Celebrating Historical Architecture

The Parisian campaign sought to establish new pollution-free open spaces and travel routes for pedestrians, bikers, and cyclists, while also highlighting the historic architecture of emblematic city squares.

Reduce Traffic Congestion & Improve Urban Planning

Parisian officials sought to measure the impact of road traffic, stop lights, and bus and metro stations on dynamic pollution throughout the day to inform city planning efforts and optimize traffic movement.

The Solution

01

Pollution Sensors Installed Across Iconic Squares

The City of Paris’ campaign launched a large-scale experiment by partnering with Cisco to install a network of noise, traffic, and air quality sensors in Paris’ busiest traffic square - la Place de la Nation. Cisco deployed and maintained the connected sensor network, ensuring continuous data collection on a 24/7 basis.

02

Incorporating BreezoMeter’s Air Quality Analytics

Cisco turned to BreezoMeter to enhance their ability to track local air quality changes and make Parisians more aware of the health risks.

 

To make the campaign’s air pollution coverage more granular, BreezoMeter advised Cisco on optimal sensor placement to bridge spatial gaps and combined its environmental forecasts with data captured by Cisco’s sensor network to analyze air quality in and around each square.

03

Live Air Quality Reporting & Insights

Using BreezoMeter’s data integration and AI-driven air quality analysis, the campaign was able to provide Parisians with actionable health-focused recommendations in real-time, providing an accurate image of personalized pollution exposure and determining health risk with a 0-100 score.

 

The data and insights empowered Parisians to involve air quality tracking in daily decision-making. Campaign agents installed touch screens at bus stations, displaying updated visualizations of live pollution data. Parisians were encouraged to adopt a more health-conscious routine, favoring lower-impact public transportation to minimize vehicle use.

04

Urban Planning With Open Public Participation

Cisco’s sensor network allowed the City of Paris to initiate a nearly-year-long shared diagnosis process where citizens could track air quality along with government officials. Open to the general public. Individuals could submit proposals, inquiries, and complaints, which city officials will consider when drafting new renovation plans. 

 

The process involved an online participatory platform, public town hall meetings, workshops, exploratory walks, forums, and questionnaires all leading to finalized goals regarding improved square traffic and public spaces.

The Results

€30 Million Budget Approved For 7 Square Remodels

Parisian officials greenlit new road work construction for 7 emblematic city squares, aided by traffic and pollution data. Renovations included improving traffic infrastructure, reconfiguring public transportation, establishing new pedestrian & cyclist-designated areas, and planting new vegetation.

New Green Public Spaces & Travel Routes

The Parisian campaign expanded the squares and improved accessibility with newer, wider pedestrian crossings and cyclist routes. It also paved new central park rings for residents to enjoy, planting new trees, shrubs, and gardens and building paved mounds that help reduce traffic noise.

Public Transportation Revamp

Bus traffic was completely reorganized for highly congested areas. Terminal stations were moved outside of the central area, and new stops were created to still allow better access to the squares. Major metro renovation work was also launched to improve accessibility.
