Summary – Urban congestion generates economic costs, jeopardizes road safety and exacerbates CO₂ emissions, and static approaches have reached their limits in the face of diverse traffic flows. Leveraging IoT sensors, real-time analytics and predictive AI dynamically orchestrates signals, prioritizes critical uses, reroutes incidents and anticipates bottlenecks with over 90 % accuracy. Solution: a modular, open-source ITMS platform deployed via microservices with edge computing, CI/CD pipelines and MLOps, smoothing traffic, reducing delays and CO₂ and avoiding vendor lock-in.
Urban congestion is no longer a mere nuisance: it incurs economic costs, undermines road safety, and worsens CO₂ emissions. Faced with exploding traffic flows—vehicles, public transit, logistics, and soft mobility—static approaches have reached their limits.
Intelligent Traffic Management Systems (ITMS) are revolutionizing road network governance by orchestrating data from IoT sensors, real-time analytics, and predictive AI. This shift toward smart urban mobility enables the anticipation of traffic jams, the prioritization of critical use cases, and the optimization of existing infrastructure without expanding the roadway footprint.
Dynamic Real-Time Flow Orchestration
The effectiveness of traffic management systems hinges on real-time data collection and analysis. IoT sensors and adaptive algorithms provide continuous visibility into the status of roadways and intersections.
IoT Sensors and Large-Scale Data Collection
IoT devices play a central role in intelligent traffic management by capturing granular information on speed, density, and flow direction. Sensors embedded in traffic lights, magnetic loops beneath the pavement, and connected cameras feed traffic analytics platforms. This heterogeneous collection requires a modular, open-source architecture to quickly integrate new equipment without vendor lock-in.
Aggregating raw data in a localized data lake or in the cloud paves the way for real-time analysis, as detailed in our article From Data to Decision. Data pipelines must ensure low latency and high security to prevent leaks of sensitive information. MQTT or CoAP protocols, combined with open-source components, facilitate horizontal scalability of the system.
Edge processing, deployed directly at intersections, complements the centralized approach. By performing certain analyses at the source, it reduces network load and accelerates response times. This hybrid configuration often relies on container orchestrators like Kubernetes, blending off-the-shelf components with custom developments.
Real-Time Analytics for Decision Making
Once data is captured, real-time analytics turn information into operational decisions. Traffic management dashboards provide operators with key indicators such as lane occupancy rates and signal waiting times. With just a few clicks, they identify pressure points and suggest signal cycle adjustments.
Stream processors, based on open-source frameworks like Apache Kafka and Flink, feed configurable business rules, highlighting the importance of MLOps practices. Detected anomalies—sudden slowdowns, potential road incidents—automatically trigger predefined scenarios without human intervention. This automation reduces reaction times and enhances road safety.
Here, the role of artificial intelligence is limited to optimizing thresholds and dynamic parameters. Adaptive algorithms continuously evaluate the outcomes of applied changes and refine their strategy. This virtuous cycle of improvement ensures enhanced performance without rebuilding the system from scratch each time.
Case Study: Swiss City Demonstrates Responsiveness
A medium-sized Swiss municipality piloted an IoT sensor network combining embedded loops and open-source thermal cameras. The goal was to streamline a major artery notorious for its critical peak hours. By blending edge computing with analytical pipelines, teams reduced the average intersection waiting time by 25% in just a few weeks.
This pilot demonstrated the value of a contextual solution: software configurations were continuously adjusted based on seasonal variations and event-driven peaks, without additional costs for proprietary licenses. The modular approach also enabled the later integration of air quality sensors, expanding the platform’s functionality.
This experiment illustrates how dynamic data orchestration and real-time analytics form the foundation of smart urban mobility, capable of adapting to evolving needs without constant manual intervention.
Anticipating Congestion with Predictive AI
Beyond simple reactivity, modern ITMS use AI to predict saturation points before they occur. Predictive models analyze historical traffic flows and current events to recommend proactive adjustments.
Machine Learning Models for Traffic Forecasting
Neural networks and supervised machine learning models process time-series traffic data to anticipate congestion. By incorporating deep learning algorithms, these models can capture non-linear flow patterns and driving behaviors. They achieve forecasting accuracy above 90% over 15- to 30-minute horizons.
Data curation plays a crucial role in projection robustness. Historical series spanning multiple seasons, holidays, and special events feed a rich training set. A cross-validation mechanism ensures prediction reliability before production deployment.
An architecture based on Kubernetes, using containers for each AI component, ensures service independence and facilitates scalability. CI/CD pipelines automatically deploy new model versions without interrupting ongoing monitoring.
Multi-Source Data Correlation: Weather, Events, and Construction
Weather and roadworks significantly impact traffic. Advanced ITMS integrate open data APIs to retrieve weather forecasts and public works schedules. Multi-source analysis detects factor combinations likely to cause abnormal slowdowns.
Traffic analytics systems also cross-reference schedules of major cultural and sporting events with public transit ridership data. This mesh of heterogeneous flows enriches predictive models and refines optimization recommendations ahead of peak demand periods.
This contextual approach allows for variable thresholds based on criticality: a sudden storm triggers a different priority management scenario than a festival. Such customization ensures strong business relevance and minimizes manual interventions.
Case Study: Leading Logistics Company Reduces Delays
A leading logistics firm sought to improve the punctuality of its urban delivery routes. It deployed a predictive model on its regular routes, integrating real-time traffic data and weather forecasts. The result: an 18% reduction in average delivery delay.
This project highlighted the value of traffic management software coupled with traffic AI: by recommending less congested time windows, the system optimized heavy vehicle routes and reduced exposure to jams. The solution’s modularity later enabled the integration of a road incident management module.
The example demonstrates how anticipation via predictive AI enhances operational resilience and customer experience, without requiring additional infrastructure—simply through intelligent data utilization.

Intelligent Prioritization of Critical Use Cases and Incident Management
ITMS can automatically prioritize certain flows such as emergency vehicles and public transit. In the event of an incident, instant reallocation of signals and lanes ensures faster response times and limits network impact.
Adaptive Traffic Signals for Multichannel Priorities
Adaptive traffic signals dynamically adjust their cycles to favor priority vehicles. Public transit and emergency vehicles receive extended green phases, reducing wait times and accident risks. This feature relies on open protocols and traffic management software capable of handling multiple simultaneous priorities.
Priority settings are configured via a centralized console where business scenarios are defined: medical emergency, delayed bus, or maintenance vehicle. Each scenario activates a dedicated software sequence that modifies intersection timings in real time.
The modular approach allows new priority types to be added without disrupting the entire network. An open-source framework ensures interoperability with existing systems and prevents vendor lock-in.
Automated Incident Management and Re-Routing
In the event of an accident or sudden jam, ITMS detect anomalies through camera and sensor analytics. Once identified, an alert triggers an automatic re-routing protocol to divert traffic. Updated traffic maps are displayed on variable message signs and through connected navigation apps.
This process reduces congestion spillover, limits secondary risks from unplanned stops, and improves road safety. Algorithms compute optimized alternate routes in real time.
Incident management also encompasses sending directives to response and maintenance teams. The integration of programmable workflows ensures coordination between IT teams, law enforcement, and emergency services.
Case Study: Public Transit Operator Streamlines Services
A regional rail operator integrated its ticket validation system with an ITMS to manage tram and bus crossings. When a vehicle accumulates a delay of more than two minutes, traffic signal cycles are proactively adjusted to favor its passage.
This solution reduced average delays by 12% on the most congested lines. It demonstrated that intelligent priority management enhances public transit reliability and encourages modal shift to sustainable options.
This case illustrates the added value of a hybrid orchestration blending proprietary algorithms and open-source components, deployed according to specific business contexts.
Toward More Sustainable Cities and Optimized Infrastructure
Intelligent traffic management systems help reduce CO₂ emissions and energy consumption. They maximize the use of existing infrastructure without requiring new road construction.
Environmental Impact and Emission Reduction
Smoother traffic reduces pollutant emissions caused by frequent stops and restarts. Dynamic signal adjustments limit unjustified idle phases, lowering fuel consumption. On certain corridors, the implementation of ITMS has cut CO₂ emissions by over 15%.
Integrating air quality sensors into the urban network provides a comprehensive view of environmental impact. The collected data feed ESG dashboards and guide decision-makers toward sustainable mobility policies. These indicators strengthen compliance with CSR objectives and enhance the public entities’ brand image.
Modular, Open-Source Extension to Avoid Vendor Lock-In
Adopting an ITMS platform built on open-source components ensures freedom of customization and long-term sustainability without exclusive dependencies. Each module—data collection, processing, visualization, AI—can be replaced or updated independently. This modularity guarantees long-term ROI and limits costs associated with technological lock-in.
Teams benefit from agile governance to deploy improvements or new features without disrupting traffic. CI/CD integrations ensure the quality and security of updates. Edana’s approach combines these principles to align the solution with business strategy and local constraints.
Microservices-based software architectures make it easy to add environmental monitoring modules. This extensibility ensures progressive system evolution without a complete overhaul.
Case Study: Mid-Sized Swiss Municipality Achieves Optimal Utilization
A Swiss municipality migrated its legacy signal system to an open-source ITMS platform while retaining the existing hardware layer. Teams deployed a set of microservices to handle data collection, processing, and display. This uninterrupted migration maintained roadway performance throughout the transition.
The confidentiality of this initiative does not hide its lesson: optimal use of existing infrastructure is possible without massive investments. Reusing sensors and intersection controllers cut the project budget by 40% compared to a traditional proprietary solution.
This case demonstrates the value of a hybrid approach, combined with strong domain expertise, to transform aging infrastructure into a resilient, sustainable mobility system.
