Traffic Monitoring & Information
From Sensors to Information.
Modern dynamic highway guidance systems are based on a multitude of sensor data that form the basis for decisions on traffic management strategies and information for people on the move. Traffic counts, the measurement of speeds and distances between vehicles, the acquisition of environmental parameters such as wind, humidity, temperature and emissions and many other data are processed in the motorway control centres.
Variable message signs are the means of informing road users about construction sites, accidents or imminent traffic jams, road conditions and alternative routes. Video surveillance enables automatic event recognition. Easily accessible data enables the operator to quickly identify problems and react accordingly. Timely and accurate travel information enables road users to plan their journeys, make reliable decisions before and during their journey and arrive at their destination on time and stress-free. Weather stations and in-road sensors provide up-to-date data to trigger winter road clearance on motorways as a preventive measure.

With long-distance freight traffic, the demand for suitable parking spaces for trucks is growing directly at or near motorways.
Benefit
- Better management of available parking spaces
- Better communication with drivers
- Increasing safety for all road users
Function
- Monitoring of individual parking spaces using magnetic field sensors, video technology or induction loops
- Counting of the difference between vehicles moving in and out via induction loops, radar detectors, ground radar or magnetic field sensors, video technology
- Tracking of individual vehicles using automatic license plate recognition (ANPR)
Reliable forecasts for efficient winter service
Benefit
- Optimized basis for decision-making processes
- Winter service when, where and how it is needed
- Shortened response times
- Drastic accident reduction
- Optical Visualization
- Economic benefits
Function
- Measuring stations collect numerous values such as road surface temperature, residual salt, precipitation, etc.
- Collected data is merged with general data from the local weather service.
- All data are combined in a time- and location-differentiated manner and form the basis for optimised winter road clearance.
