Green city traffic

Environmental monitoring through traffic data

The possibility of integrating different sensors to a single Data Processing Station allows for real-time correlation of traffic data with environmental parameters such as air or noise pollution information in a specific area.

The environmental sensors capture the air pollutants that can be directly associated with the traffic data detected and analysed by the Sensefields sensors. Based on the pollution levels, the traffic is being managed through
warning alerts that activate the road signals in order to ensure minimum pollution of the zone.

  • Real-time monitoring of traffic data such as intensity, occupancy, average speed and vehicle classification in correlation with environmental pollution data:
    • Level of greenhouse gases: CO, O3, NO, NO2, H2S, SO2
    • Partículas suspendidas: PM1, PM2.5, PM1Suspended particles: PM1, PM2.5, PM10
    • Noise level: dB
  • Possibility of setting limits for alarm generation
  • Data collection for the design of traffic contingency plans

This solution allows city managers to make preventive decisions in order to control the pollution
generated by vehicles, using real-time data to modify traffic patterns


Removable and disposable batteries and electronics.


Replacement or battery change within a few minutes.

Ready to use

Collection and analysis of traffic data from the first minute of installation. Predefined configuration “Plug & Web” solution: connect sensor and start collecting data without any further configuration.

Self-calibration of the detection thresholds

It is not affected by structures in the road so it can be used in urban tunnels. It can be installed in areas close to metro lines, railway stations.

Highly accurate

Accuracy not affected under heavy weather conditions and visual factors such as shadow and lighting. Not affected by occlusion.

Fast, simple and low-cost installation

Minimal infrastructure intervention with a minor perforation in the pavement. Minimum time of road intervention without extensive engineering work, destructive trenching or cutting required and wires required.

Low maintenance costs

Battery life up to 10 years under standard conditions. No specialised personnel or tools required.

No recalibration required

No loss of reliability with the pass of time. Recalibration not required.

Standalone solution

No router, server, PLC or electric cabinet required. Possibility of installing without a dedicated electrical connection via solar panel or partial supply from a street lamp.


Direct and easy integration with Traffic Management Centres and local devices such traffic lights, traffic signals and VMS


Sensors and batteries can be removed from the enclosure for reuse in other installations either as permanent or temporary solutions for prospecting, monitoring and auditing.


Works in any climate and usage conditions thanks to the rugged enclosure that supports long time exposure to severe weather conditions
