Variable speed regulation

Real time calculation of the optimal driving speed

Offering the opportunity of monitoring the traffic flow in real time, Sensefields technology allows for real time calculation of the optimum driving speed, which is being communicated to the drives of the highway according to the patterns of the traffic behaviour.

The recommended speed is obtained by applying customised algorithms fed by real-time data of intensities, time headways, occupancy levels and instantaneous velocities for each lane. Of course, incidents that occur on the road are also a significant factor when calculating the optimal driving speed.

  • Traffic data to feed predictive behaviour models and configure alarms in certain scenarios
  • Combination of information per lane provided by multiple stations running as a single system through the Collector Server
  • Integration and direct communication with existing messaging panels on the track
  • Measurement points can be easily added, modified or deleted to accommodate changes in traffic patterns.

The variable speed regulation solution is applied to increase road safety and decrease accidents caused due to the accordion effect. Activation of visual and sound road alarms due to anomalous behaviour can contribute towards preventing road fatalities, offering a more secure journey for the user.


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
