Effective traffic calming and sustainable urban development require a sound, objective basis for decision-making. The city of Salzburg is therefore implementing permanent traffic monitoring at central intersections. The aim is to continuously record traffic, and on this basis, to plan, control and evaluate measures.
The technology used is the BERNARD Mobility Analyser (BMA), a camera-based traffic recording system developed by the BERNARD Gruppe. The sensor system makes it possible to record the direction-dependent volume of traffic, differentiate between road user classes such as people, cyclists, cars and trucks, based on TLS 8+1 of BASt (German technical supply conditions for roadway station units), analyse turn-off relations, and record speeds. Data is collected in real time directly on the system – day and night, and under different weather conditions. This creates a consistent and reliable database. The BERNARD Gruppe is responsible for the entire range of services – from concept development and site planning to installation, configuration and commissioning, to ongoing maintenance of the counting points, and to ensuring recording accuracy. The installed systems are supplemented by buffer batteries to bridge periods when the local infrastructure is without power during the day and to ensure uninterrupted data collection. A powerful software solution with a user-friendly web interface complements the hardware. In addition to device management, it enables the structured analysis, visualisation and evaluation of the data. Real-time data provision allows traffic flows to be monitored in detail and traffic-relevant developments to be detected at an early stage. Continuous time series also provide an objective basis for the evaluation of traffic organisation adjustments, for the optimisation of complex intersections, and for transparent communication with decision-makers and the public. Traffic calming measures can thus be reviewed based on facts and developed further in a targeted manner. Special attention is paid to data protection. The BERNARD Mobility Analyser meets all legal and data protection requirements. The information is provided directly on site – no videos and no personal data are stored. The survey is anonymous and is used exclusively for traffic analysis. With this project, the BERNARD Gruppe underlines its claim to implement engineering services of technical quality and innovative strength that can be trusted, and to support the city of Salzburg in making traffic safer, more efficient and more liveable.
