Connected Mobility


Intelligently digitalised roads

Intelligent digitalisation of road networks is of critical importance for economic growth and quality of life. This is why Siemens Mobility has developed ESCoS V2x technology.  ESCoS is a secure, cooperative technology for communication between all kinds of vehicles and the infrastructure.  Vehicle2x is part of the growing "Internet of Things". ESCoS Road Side Units provide key data for a more precise picture of the current traffic situation, enabling more efficient traffic control, a significant reduction in accident numbers and an even greater cut in emissions than possible up to now.

Inclusive vision: Car2x, Rail2x, Ship2x and Airplane2x

Vehicle2x, Rail2x, Ship2x, Airplane2x

Car2x is ready to go                                                                                                  Rail2x, Ship2x and Airplane2x will use our Stratos ESCoS solutions for rail networks, waterways and airfield taxiways in the future.

The intelligent system for communication between road vehicles and infrastructure.

When it comes to communication, Car2x is the solution: Siemens Mobility's cooperative traffic management system allows vehicles to connect with the infrastructure and the traffic control centres.  The Road Side Unit (RSU) provides the vehicles directly with time-critical data such as SPaT (Signal Phase and Timing) while non-time-critical information such as IVI (In-Vehicle Information) is transmitted from the cooperative Stratos traffic management centre via LTE to the cars.  The result: more effective prevention of congestion and accidents and a stronger reduction in pollutant emissions - essential factors for cities and other municipalities aiming to improve quality of life and boost economic growth.


Car 2x - this is how the smart technology works:

  • The infrastructure components are equipped with  RSU technology
  • The cars use the RSU's GPS and their own Car2x onboard units to continuously report their position, speed and direction of travel
  • The traffic management system transmits traffic information, traffic restrictions and hazard warnings.
  • The control centre uses the available Car2x information for more efficient traffic control and guidance
  • Integration of all required international V2x communication standards
  • High security standards including PKI
  • Open interfaces to communicate with controllers via standard connections
  • Defined security concept for maintenance purposes
  • Spare interfaces for future connection of innovative technologies 
  • Full hardware and software compatibility with all Vehicle2x solutions
  • Deployment as stand-alone or integrated solution
  • Complete integration into the Siemens Mobility Stratos system 
  • Full compliance with EU and US standards
  • Easy installation
  • Modular concept enables the creation of project-specific solutions and facilitates adaptation to future requirements
  • Multi-purpose mounting system
  • Highly accurate positioning performance
  • Improves road safety and reduces accident numbers
  • Optimises the flow of traffic, minimizing congestion and stop-and-go traffic
  • Shortens travel times
  • Helps reduce traffic-related emissions
  • Boosts your municipality's image by positioning it as a sustainable "green city"
  • Contributes to lasting improvements in the quality of life acriss entire conurbations
  • Vehicle2x infrastructure supports automated and autonomous driving

JCT Symposium 2021: A new flexible Signal Phase and Timing (SPaT) algorithm and Connected-ITS enabler in Manchester

This presentation reviews the development, application and impact of a new SPaT algorithm recently tested in Manchester as part of Project Synergy.  Deploying SPaT on the largest and most complex intersection to date has provided a number of insights into the value of SPaT and related C-ITS messages in the future deployment of connected autonomous vehicles.  This presentation shares these findings and reviews the challenges and benefits of integrating SPaT and MAP messages with on-board technology.

The innovative field device for Vehicle2x

The technological heart of Vehicle2X consists in the cooperative control centre Stratos and the field device RSU for establishing the connection.  Stratos has been designed to integrate the complex structures of urban and interurban traffic control centres.  Developed to communicate via WiFi 802.11p and LTE-V2x with any vehicles equipped with this standard, the RSU is a perfect fit for urban road networks and motorways alike.

ITS-G5 is ready to roll

And what is ITS-G5? ITS G5 is a broadcast technology, capable of delivering secure ad-hoc direct vehicle-to-vehicle and/or vehicle-to-infrastructure communication. C-ITS (Cooperative Intelligent Transport Systems) are the technologies associated with the concept of sharing information and working together. Siemens Mobility and other leading road traffic companies support the swift deployment of the right framework conditions for improving road safety and traffic efficiency.

The future of traffic management

These four trends will have a lasting impact on our mobility behaviour: Car-Sharing, the connection of infrastructure with vehicles, e-vehicles and autonomous driving, are already indespensable today.  Let us take you on a journey along the digital path of mobility!

Inclusive vision: Car2x, Rail2x, Ship2x and Airplane2x

There are many places where the routes taken by road vehicles intersect with those of other means of transport such as trains, ships and even airplanes (on the airfield). Our vision of the future transport “Internet of Things” includes constant communication between all those elements – a goal that we continue to work on every day.

The new Siemens Mobility EcoSystem Cooperative System road side unit (ESCoS RSU) puts in place the necessary infrastructure to allow a two-way communications to be established between traffic systems and vehicles equipped with the same technology.

These units adopt low-latency Wireless LAN-based 802.11p ITS-G5 dynamic short-range radio technology in accordance with relevant ETSI and ISO standards, interfacing to the Siemens Mobility Stratos cloud-hosted traffic management system.

The ESCoS RSUs can also be connected to a Siemens Mobility ST local traffic light controller, extracting signal phase and timing information as well as providing the ability for traffic priority demand to be requested by authorised vehicles (e.g. emergency services, public transport) to reduce emissions caused by unnecessary braking and accelerating.”


Uses of the technology

Satellite-based prioritisation systems for mass-transit and rescue vehicles, coordinated green phases for cyclists, intelligent road traffic digitalisation, electrical buses or a smart flow control system for trucks –  Connected Mobility Solutions from Siemens Mobility help make urban traffic management even more efficient, sustainable, cost-effective and safer.
