URBAN

Urban densification, the growth in human transport, the saturation of road traffic and air pollution are issues faced by many cities, both large and small. To confront these challenges, local authorities are driven to improve existing urban transport systems and build new metro, tram and bus lines, whilst developing routes for sustainable mobility as well.

Urban transport operators are no longer simply being asked to improve their performance and ensure the operation and maintenance of existing lines that get more challenging by the day. They are also being asked by public authorities to carry out a new important mission: improve the services and expand the network. To accomplish this double mission whilst also managing projects of increasing complexity, they are seeking out competent and effective external support that can quickly understand their needs and mobilise all the resources and expertise that will be required. This external support has to apply skills in the latest technologies and managerial methods that are right for the urban network and for the provided services, both at present and in the future.

Against this backdrop, our team of specialists, engineers and technicians – with international experience also on both the industrial and operational levels – is perfectly capable of meeting the requirements of urban transport companies, by virtue of its ability to understand their requirements as well as industrial products and processes. We provide expert advices, engineering and consultancy services for metro, tram, tram-train and bus lines and depots. Our emphasis is on engineering and system architecture, signalling and automation, whether driverless or not (STO, DTO, UTO), management systems and control centres, telecommunications, safety (RAMS) and ventilation. Our experience puts us among the leaders in these domains.

 

Domains of activities

  • Metros, whether driverless or not

Control centres and SCADA

Control Centers are the brain of transports system. They provide monitoring, management and assistance to the operators. By ensuring proper and coherent supervision of equipment from the whole transport system, they enable its regular operation.

Control Centers are critical for the operation of the whole system.

Besides Control Centers, telecommunications are the central nervous system of transports. They are the path by which all data communication is carried out to ensure the proper operation of the whole system, in proportion with their relative importance for it.

GESTE’s teams have developed skills in those both fields and are up to offer high-level services to their clients and partners.

Safety and ventilation

Safety and ventilation are essential questions to the railway and urban transports.

In today’s society, which seeks to have total control over events, the safety of people and infrastructure has become a primary concern. It is an objective in itself, and a highly sensitive issue in our time. As a result, risk is increasingly considered unacceptable, both for individuals and groups of people.

Ventilation is an inherent dimension of safety in the transports sector and plays a role apart in transports projects. In the confined space of the tunnel, aerodynamic and thermal phenomena, the spread of smoke in the event of a fire, comfort and emergency ventilation, the flow and evacuation of persons, the intervention of emergency services and the protection of people and infrastructures now play a critical role and are given consideration early in the design phase of new transport systems and underground structures, as well as when modernising the existing infrastructures.

These two issues, ventilation and safety, are cross-cutting themes to transport systems, which call for specialized skills. This is why GESTE chose to treat them apart from the RAIL, URBAN and ROAD fields, in two cross-cutting fields: RAMS (safety) and FLOWS (ventilation).

GESTE Engineering énergie ligne de contact

Overhead line, power supply and cables

The growth of urban landscape and urban transportation lines induces a growing market for the overhead line, its adaptation or it construction. As they are linked to numerous interfaces, works related to the overhead line are often complex.

To ensure the energy supply for the whole system is one of the strategic problematics in the urban transportation. The traction current is a particular form of energy that reacts to big load variations over very short periods. With an alternative or a direct current supply, at a voltage that can be of 600 V up to 25 kV, this current can be found under numerous variants. Managing this variety, added to the interface between the overhead line and the whole system, calls for narrowly-defined technical skills.

Thanks to their wide experience, our engineers are up to answer this challenge with professionalism and efficiency.

Operation and maintenance

To face the variety of specific requirements coming from public authorities, urban public transport companies must expand their network, their production tools and their vehicles fleet, what requires to take in consideration both technical and economic criteria. New transportation systems are developed and put into operation, which implies significant adjustments regarding their operation and maintenance.

GESTE Engineering and its team of multidisciplinary experts support these companies in those activities.

Automation, signalling and remote controls

To meet the ever-more demanding targets related to safety and performance, major cities begin to look towards automation and signaling and towards the interesting answers that these technologies bring with them.

Automation and signaling pilot the automatic train movements in applying operation programs defined by central control units.

As a precursor in that field, GESTE has developed a mastery of the most common languages (SCADA, CBTC) which now allows the company to perform on urban transport systems (metros, trams, etc.) as well as on classical railway systems.

GESTE Engineering ingénierie architecture système

Systems engineering and architecture

As the skeleton of transport system, Systems architecture is responsible for its functions design and its components design as well as for the interrelations between those. Systems architecture lays the foundations for the whole system and for the project. Defining it implies to adopt a global understanding of the issues, which embrace various aspects such as functional, technical, industrial problematics and contractual requirements.

On that field, GESTE Engineering provides upstream consulting, project management and assistance to the technical program manager.
