Transport infrastructures are facing a number of factors that strongly affect existing and future systems. Energy transition, increasing urban mobility and multiple interconnections between cities and countries are all new challenges.

The current state of transport infrastructures cannot cope with the continuous increase in the number of transport users.

The global phenomenon of urbanisation, environmental issues and interoperability needs will radically change transport systems. Stricter requirements for safety, reliability, comfort and environmental standards will also have to be met.

The disruptions offered by digital technology will also revolutionise projects and transport infrastructures, which have become complex, due to the increasing number of users.

Transport infrastructures

Find solutions for ageing transport infrastructures and high population growth

Faced with the increasing number of users of public transportation, the challenge is to maintain the existing infrastructure and increase the capacity, while also ensuring continuity of service. Renovation and maintenance operations must be seen as an opportunity to introduce digital technologies that offer predictive maintenance solutions. These should guarantee that the system run smoothly and is reliable, with minimal or no downtime.

sustainable infrastructure

Develop sustainable infrastructures that consume less energy

Infrastructures must become ‘smarter’. They must incorporate modern information and communication technologies to ensure efficiency and environmental performance via effective traffic management and high-performance information and alert systems. The use of PLM (Product Lifecycle Management) tools is a system-based approach that has become indispensable to ensure control over construction costs and energy management.

energy transition

Meet the challenge of international competition between territories

To make themselves attractive to investors, territories must have an efficient transportation network offering local services. The challenge is to offer the safest and highest quality services possible (reliability, comfort) in compliance with environmental standards, while meeting specific needs of each territory and its users. This means offering diversified, up to date and economical solutions.

Take into account the critical nature of transport infrastructures

Transportation networks have a crucial role in our society. They are the lifelines to our territories and places where people gather and interact. To guarantee smooth and fluid operations, it is indispensable to have reliable and safe facilities that provide services to meet the users’ needs, made possible by implementing digital solutions and systems.


International engineering group Assystem has over 50 years of experience in complex and restrictive environments. Our major strengths lie in managing large infrastructure projects and our ability to integrate systems.
These two assets form the core of our expertise and enable us to provide assistance to public and private players in urban, suburban, regional and international networks, both for rail and air transport.
The systems delivered by Assystem for transportation networks are instrumentation and control systems (signalisation, CBTC, ATS), system equipment (rolling stock, railway, electric traction, overhead lines, garages) electromechanical equipment (HVAC, smoke extraction, people with reduced mobility, elevators, escalators), power distribution (transformer and distribution substations), information and surveillance systems (passenger information systems, vehicle scheduling control system, video surveillance).
Assystem also helps with the construction and renovation of buildings used as maintenance facilities and railway stations.

Rail transport performance – a data science subject!

"Rail infrastructure to deliver the highest possible availability levels in order to guarantee continuous public service. Exploitation and optimization can not be done without the structuring of data volumes and their analysis in deph, in part, by artificial intelligence."
