Communication Solutions for Intelligent Transportation Systems
Reliable network communications are a critical necessity for monitoring and managing increasingly complex transportation infrastructures. Knowing what is happening and where, from tracking buses and trains on their routes, to locating and addressing stalled vehicles, to connecting drivers with important information about road and traffic conditions – effective traffic management demands intelligent transportation systems.
Complete connectivity for today and tomorrow
Reliable network communications are a critical necessity for monitoring and managing increasingly complex transportation infrastructures. Knowing what is happening and where, from tracking buses and trains on their routes, to locating and addressing stalled vehicles, to connecting drivers with important information about road and traffic conditions – effective traffic management demands intelligent transportation systems.
Siemens solutions can
- Synchronize traffic lights to keep vehicles moving
- Provide drivers with information to help them make smarter decisions on the road
- Deliver accurate and timely information to transportation managers so they can prevent bottlenecks before they happen
- Withstand harsh environments – with products that comply with NEMA TS 2 environmental requirements and operate reliably in extreme temperatures
First-class, integrated network solutions
On highways, down innercity streets, through tunnels and railway crossings. An endless stream of cars, trains, buses. Traffic is a complex, nonstop challenge for major city centers and small communities alike. Coordinating traffic, staying on top of its ebbs and flows, is a complex, demanding task for emergency support personnel, city planners and transportation system operators everywhere. A constant stream of up-to-the-minute data can help transportation system operators stay one step ahead of traffic issues. However, with limited budgets and compressed time frames, implementing a state-of-the-art communications infrastructure can present additional challenges. So can finding network solutions that can survive the harsh conditions faced by 24/7 intelligent transportation systems including extreme temperatures, vibration and electromagnetic interference.
Pedestrians, cyclists, cars, trucks, light rail, transit vehicles – urban transportation networks present city planners with unique challenges. With aging infrastructure and shoestring budgets, many agencies at different levels, creating intelligent transportation can be complex and challenging.
Siemens provides a broad array of networking solutions that help cities address these challenges and achieve their goals – quickly and cost-effectively.
Highlights
- Ethernet over VDSL (EoVDSL), a cost-effective solution for transmitting Ethernet data over existing copper wiring, enables you to reuse legacy infrastructure to deliver broadband speeds

- High bandwidth, multiservice backbones with 10 GigE uplinks, advanced layer 3, MPLS and PIM-SM multicast routing services for managing video traffic
- Compact, fiber optic switches with Power over Ethernet (PoE) for simplified device connectivity
Applications
- Whether in small interchanges or highly complex traffic control systems, Siemens provides solutions that control traffic flexibly and enable the rapid, dynamic management of traffic situations
- Influence the traffic flow measurably through predefined strategies such as a green wave or public transportation priority to reduce congestion
- Connect field devices such as sensors, cameras (CCTV), message signs, RFID, and payment systems to a local or remote back office through secure TCP/IP Ethernet
- Eliminate needless trenching of conduit while maintaining security with SCALANCE Wireless LAN
- Secure remote access for maintenance and troubleshooting no matter where the solutions are located
- A focal point where field networks converge with corporate IT networks
- Operators rely on many streams of data from field elements to ensure the smooth operation of complex, multimodal transportation networks
- Reliable, high port density, high bandwidth is a necessity with contingencies in case of a major event
Geographically dispersed, covering many hundreds of miles and kilometers of roadway, interurban networks are a unique challenge to manage. These interurban networks serve as a critical information backbone for the entire transportation infrastructure. Ensuring there is the significant bandwidth required to connect thousands of devices and support hundreds of real-time video feeds, along with data gathered from roadway sensors, is critical.
The impact of a network outage is significant. Without a reliable network, operators are unable to effectively manage and respond to an event. High reliability and operational uptime in extreme environments is key.
Siemens solutions have been purpose-built to create wide-area networks that supply reliable, high-bandwidth connectivity in some of the world’s most demanding environments.
Highlights
- Highest level of network security keeping unwanted visitors out
- Outstanding reliability and scalability for future needs
- Exceeds environmental conditions as defined by the NEMA TS 2 industry standard (ranging from ‑40° C to +74° C)
- Long-haul fiber optics that provide high-bandwidth connectivity even for remote locations
- Multiservice backbone with 10 GigE uplinks, advanced layer 3 and MPLS routing services
- Wireless RUGGEDCOM WIN and SCALANCE W complete the link by connecting locations that are too difficult or expensive to reach with fiber optics
Applications
- Monitoring systems help prevent traffic jams on the freeway before they have a chance to form
- Analyzes the data provided by all connected sensors and systems and generates the appropriate measures for intervention
- Roadway section control: manual or automatic (e.g. congestion and incident alerts, weather warnings on fog or wet roadway; temporary opening of hard shoulders)
- Helps to maintain and refinance roadway infrastructure
- Enables the guidance of traffic to lower-density routes and ensures mobility in chronically congested urban areas
- Ensures the provision of value-added services to operators and transport companies
- Lowers the technical and administrative expense of implementing and maintaining tolls
- A focal point where field networks converge with corporate IT networks
- Operators rely on many streams of data from field elements to ensure the smooth operation of complex, multimodal transportation networks
- Reliable, high port density, high bandwidth is a necessity with contingencies in case of a major event
Bridges and tunnels present unique safety challenges, including the risk of fast-moving fires, accelerated heating rates, the risk of structural collapse, and longer escape routes.
Accidents and closures can severely disrupt your city’s transportation systems. To protect public safety, improve availability and lower operational costs, your network subsystems need to interact seamlessly. You must be able to detect incidents early, perform rapid mitigation and recovery inside tunnels, and protect critical systems – all within regulatory requirements.
Siemens provides the transportation network solutions that our customers can depend on when they need them most. By combining offerings from other Siemens divisions, we deliver a totally integrated automation solution for bridge and tunnel communications.
