Traffic Control / Information

Only detailed and reliable information about traffic conditions allows appropriate evaluation and controlling processes. Siemens offers customized products for collecting traffic data at various locations. In addition to the classical loop detectors, Siemens offers modern overhead detectors that eliminate the need for underground engineering for installation and maintenance.

Siemens video detectors are particularly suited for use at intersections, collecting traffic data, or identifying problems on highways or in tunnels. Even under difficult lighting conditions, these systems document the traffic conditions safely and reliably. The possibility of transferring video images to a control center makes traffic data available for other purposes as well, such as security services.

Sometimes detectors are needed in locations where there is no power connection or wired communication connection. For those cases, Siemens offers TrafficEye, an infrared-based detector powered by solar panels that transmits data via GSM or GPRS.

SITRAFFIC Concert is the Siemens traffic management control center. The system collects, bundles, and evaluates traffic data from different sources and distributes it to various users.
Furthermore, the system can intervene in a targeted manner, either automatically or manually, via mouse click. Concert integrates all traffic flows, including parking traffic and local public transport, as well as different traffic areas (city center, highway, country).

PLC 2000 is our parking guidance system. Due to its modular structure, it is scalable for any application, and can be expanded from a basic system for a parking control center all the way to a large-scale parking guidance system with multiple-space functionality. This modularity also applies to the functional specification of the system.

End users of traffic information not only want to know where and when traffic jams and incidents are occurring, but also how long they will need to reach their destination and which route is recommended. For that purpose, travel times of individual traffic elements on particular routes are documented anonymously and evaluated in combination with other traffic data.
Siemens provides the information learned in the process to its customers, enabling drivers to reach their destinations more quickly.

In addition to the internal processing and utilization of the traffic data generated, Siemens also offers the option of connecting subsystems. Traffic information can, for example, be shown on the Internet or transmitted to radio stations. There is a broad spectrum of possibilities for providing comprehensive information to all parties involved in traffic control.

Siemens offers solutions for predicting and defining traffic conditions, forecasting future traffic densities, calculating and predicting travel times, and generating complete traffic reports.

Variable message signs can be used to present motorists with timely information on traffic conditions. They can also be used to dynamically adapt speed limits and thus prevent unnecessary traffic slowdowns due to rigid speed limits. Other traffic regulations, such as "No entry," can be displayed temporarily to aid in situational adaptation of traffic controls. Variable message signs can be fitted with sensors, for example to detect weather conditions, and selectively display ambient condition information relevant for motorists.
