Three real-world cases

Roundabout traffic lights on a real site

On a motorway interchange, two units detect queue build-ups and the roundabout relay extends the green light of the loaded approach.

Smart alternating traffic at a work zone

Two units detect the queues and a third watches the work zone: the traffic-light controller releases the congested direction first.

Relay-driven variable message sign

One unit measures 7 lanes (jam, speed, noise, pollution, bikes and pedestrians, wrong-way) and drives the sign relays by radio: 3 relays encode the displayed message.

Application Examples

Vehicle Counting & Speed Measurement

Count vehicles in real-time and measure their speed. Statistics by hour, day, week or month. Automatic classification by vehicle type (cars, motorcycles, trucks, bicycles). Data export for analysis.

Traffic Management & Signal Control

Place 2 VIAprevent units on two roads 2 km apart. When one detects saturation (configurable thresholds — e.g. 3 vehicles below 10 km/h), the system automatically activates load balancing at nearby intersection lights.

Nuisance Assessment & Measurement Campaigns

Quantify road noise 24/7. Quantify speeding vehicles. Automatic correlation between noise level and vehicle type (motorcycles, trucks...).

Wrong-Way Detection

Immediately detect any wrong-way vehicle using combined radar + AI. Automatic activation of emergency signage via integrated relays to alert road users.

Air Quality Monitoring

With the optional Bosch BMV080 sensor, continuously measure PM1, PM2.5 and PM10 particles. Time-based analysis with automatic traffic correlation to quantify pollution peaks. Automatic alerts when thresholds are exceeded.

Coordinated Multi-Site Network

Create an intelligent mesh of multiple VIAprevent units. Automatic coordination for load balancing management, travel time tracking and flow optimization across an entire route.
