MONITORING

The purpose of monitoring is to determine the traffic situation – observe, understand and anticipate. By providing all data and information concerning traffic, may they be current and predicted, we offer the basis for decision-making for optimized measures.

Benefit from data history

Successful traffic management requires the best achievable knowledge about the actual traffic situation. This concerns both, the current traffic situation as well as predictions about the development of traffic in the near future. The latter can be achieved using a statistical base of historical data.

Processing static detector data

The basis for the gapless data collection is the acquisition of detector data for traffic and the environment. Among other things, they provide information on road conditions or the weather.

Analyzing vehicle-based data (FCD)

In addition, the collection of data from mobile sensors - like floating car data or floating phone data - provides detailed information on traffic states and congestion events. With this detection technology it is also possible generate information for road sections which are not equipped with road-side detectors. Our systems back the functionalities of an on-line map-matching and the on-line evaluation of the individual vehicle related data in real-time operation.

Merging data

The knowledge-based fusion of static and mobile traffic data leads to a maximum of information on the traffic state and possible disturbances in the traffic flow. This level of information forms the solid basis for a reliable decision making.

Constant optimization

Raw data is checked for plausibility and, if necessary, completed applying appropriate algorithms. Data is permanently archived and made available for reporting and analysis. This ensures traceability and constant optimization of all control measures.

Facilitating exchange

Additional information is integrated through exchanges with adjacent centers to account for traffic flow from outside as well as other modes of transportation.

Mapping traffic

Tools for traffic statistics and analysis are used to derive a statistical data basis, representing typical traffic situations in the road network, taking classified events into account.

Providing an overview

The traffic data base established using the above mentioned methods is used for the determination of the traffic situation, which offers a comprehensive picture of the traffic conditions for the road network:

• identification of traffic situation
• determination of travel times
• calculation of predictions
• merging of different sources (data fusion)
• automatic incident detection
• traffic analysis with recognition of specific patterns
• analysis and forecasting of congestion behaviors
