Strategic Traffic flows are always growing and becoming more diverse, and the consequent stress is steadily increasing. In many cities, traffic requires improved planning and control that makes more sense strategically and suits the situation.

SITRAFFIC Scala is a new traffic technology platform that breaks down the former strict boundaries between system worlds. This allows for customized solutions with the precise functionality required at any given time. Users can assemble the specific functions they need for their traffic computer – even if those functions belong more in the realm of management systems. SITRAFFIC Scala gives users the option of expanding their solution as needed, based on traffic development and budget.

The SITAFFIC Watch monitoring system allows cost-effective, remote monitoring of traffic-light systems via cable or wireless communication. SITAFFIC Watch also increases traffic safety through its improved problem identification and shorter down time in traffic-light systems.

Control systems are a crucial component of information exchange between control centers, detectors and signaling devices. They must take into account the often-changing demands of different cities all over the world. Precision and reliability have always been the hallmark of our products, even under very demanding operating conditions.

Whether in small interchanges or highly complex traffic control systems, Siemens control systems are versatile, on-site traffic control hubs. In addition to pure control functions, they also offer the option of traffic data collection with 4-channel loop detectors, passive infrared detectors, or video sensors. They are compatible with existing systems and can be expanded one module at a time, for example with priority systems for local public transport. Using special user-oriented software, operators can maintain the controlling devices quickly and cost-effectively, program them, and conduct error diagnostics independently.

Behind the simple display of the colors red, yellow, and green stands a complex technology containing great diversity. Siemens covers the whole spectrum, from the classical signal light all the way to modern LED technol-
ogy and all signaling devices are fully adapted to the Siemens controlling devices.

The use of LED technology provides significant energy savings, increases the availability of the traffic light system, and makes an active contribution to protecting the environment. Siemens offers attractive financing for LED signaling devices, which allow you to offset your investment against the ongoing cost savings.

Only detailed and reliable information about traffic conditions allows for 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 can document 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.

Giving priority to public transport without putting undue strain on individual means of transport – a task that Siemens achieves using modern data collection and controlling systems. With comprehensive system solutions, Siemens can reduce waiting time at traffic lights. To accomplish this, the phase process of the traffic lights is modified and the requirements of local public transportation are given special scrutiny.

Modern communication systems that use infrared or wireless transmissions document the requirements of buses and trains. Customized traffic-based controls then access current controlling processes, which are timed to the second. There are numerous tools for precise evaluation and extensive analysis of the resulting bus and train traffic data. Based on these analyses, the traffic-based controlling of public transportation can be continuously optimized

Cyclical traffic flows and temporary capacity bottle-
necks require flexible methods of traffic control. Lane signals can be used to create additional temporary capacities in one driving direction, or to indicate a lane change, such as at construction sites.

Siemens solutions guarantee the highest level of safety. Our solutions are particularly useful for commuter traffic that moves mostly in one direction at certain times and in the other direction at other times.

Traffic technology requires the exchange of various types of data at many levels. One of the core issues is the linkage between centralized systems and traffic control devices.

The new SITRAFFIC Canto transmission system by Siemens handles communications tasks especially well. This communication system also allows the connection of older control devices to modern control centers. Siemens actively supports the OCIT initiative for streamlining multiple manufacturer interfaces. In addition to the classic wired communication, Siemens also offers wireless transmission procedures such as GSM and GPRS.

A customized solution is provided after a thorough analysis of the existing infrastructure. All Ethernet variants such as LWL, OTN, and DSL are supported.
