Realistic Simulation Supports Expansion of the London Underground

By Akio

Dubbed “one of the most complex tunneling projects in the U.K.,” the Bond Street Station Upgrade (BSSU) project is being carried out to satisfy growing traffic demands within London’s busiest shopping district, the West End.

Upon its completion, Bond Street Station’s daily passenger numbers are expected to rise from 155,000 to 225,000.

A project this complex in nature has to consider the existing tunnel infrastructure, as well as the stress and strains imposed by the surrounding soil layers for the development of new tunnels.

Dr. Sauer and Partners was contracted to provide such tunneling expertise. The company took on responsibility for preliminary-to-detailed design and construction on all BSSU sprayed concrete lined (SCL) tunnels.

Using FEA simulation, they were able to virtually test the ground through which the tunnels are being dug alongside the existing tunnel structures.

This realistic assessment enabled them to improve upon the preliminary design, as well as bring greater confidence to the overall approval process.

To learn more, read the case study, “Tunnel Vision” to see how realistic simulation plays an important role in tunnel excavation.

We also encourage you to download the whitepaper by Ali Nasekhian, Sr. Tunnel/Geotechnical engineer at Dr. Sauer and Partners, which highlights the merits and shortcomings of large 3D models in tunneling.

Modul’Air, a finalist for the prestigious International Design Excellence Awards (IDEA), offers a radical rethink of the urban mobility experience.

A central goal of the new public transportation system redesign was to harmonize human activity and nature in the French city of Grenoble.

The result is an innovative system of pods, transporting passengers and freight, which seamlessly connect, scale up and down according to volume patterns, and integrate with ground transportation modes.

The resulting passenger experience is extraordinarily painless and transparent—an obvious solution in hindsight. By design, Modul’Air lowers the barriers to utilizing public transportation and frees up ground space for a healthier environment and higher quality of life.

Eiffage’s Foresight Lab, Phosphore, and Dassault Systèmes Design Studio collaborated on the development of the Modul’Air experience.

In the process, Eiffage forged strategic partnerships with new business partners, in particular cable infrastructure builder POMA. Modul’Air project contributors leveraged the 3DEXPERIENCE® platform, which is now available on a cloud environment.

The Dassault Systèmes Design Studio provides holistic design innovation and implementation services for any industry. Design Studio partners become actors of innovation, bringing human understanding to the design process through advanced visualization, social collaboration, and decision-making applications.

Autonomous Cars in the Age of Experience

By Thomas

AKKA Link&GoCustomer buying behavior is fundamentally changing. Living in mega-cities, they often have to cope with traffic congestion and pollution. According to the World Health Organization, more than 1.2M people throughout the world are killed in car crashes every year. Human error is to blame for at least 60% of traffic fatalities. Vehicles are, in fact, mission critical systems because of the sheer mass they move in a fairly open system.

Now, customers care more and more about aesthetic, economic, driving performance, or unlimited technology. That is why the Transportation and Mobility industry is now exploring how to deliver the optimal “experiences” to their consumers. We are on the brink of a new technological revolution: the “self-driving” vehicles.

Olivier Sappin, Transportation & Mobility VP at Dassault Systèmes, provides a quick overview of this technological breakthrough:

Validate Customer Experience

Autonomous driving makes it possible to create entirely new driving experiences. The industry is thinking about how autonomous cars would “move” people, and not just in the literal sense. Self-driving cars could encourage work, relaxation or conversation. Passengers will spend their time in a more meaningful way. Autonomous cars will enable you to watch TV, listen to music, text a friend, or even eat dinner… without looking at the road ahead. As today’s drivers want to connect their various mobile, entertainment and GPS devices to optimize their vehicle environment, the new era of Transportation & Mobility starts to encompass social experiences. And these advancements will also improve productivity!

Self-driving cars make it necessary to test new types of vehicle-driver interaction. Now, consumers are fast becoming more comfortable with intelligent transportation systems: automatic parking, collision-avoidance systems and telematics. As a result, consumers of all ages are surely becoming prepared psychologically to cede control of the steering wheel.

So the idea is to challenge traditional automotive design. Automobile interiors will be redesigned so that seats can swivel sideways to face other passengers instead of facing forward, and desk surfaces will be built into the cabin walls.

New Levels of Complexity To Be Managed

Automakers are increasingly developing cars that drive themselves. Audi, BMW, GM, Nissan, Toyota, and Volvo all have announced plans to “unveil” an autonomous car by 2020. But Google is further ahead in this development than traditional industry leaders (Google is to release publicly a prototype in 2016). Autonomous vehicle drive systems are electro-mechanic and driven by software. That is why the industry strives to build cars from a systems model which allows them to validate functions including electrical, software and hardware.

Connectivity within and between vehicle environment is still a huge challenge. Vehicles can collaborate, interpret data from other vehicles around them, from surroundings, with the “Internet of Things” and improved GPS technology. Thanks to sensors allowing them to drive closer together, autonomous cars will accelerate and brake more efficiently than humans, increasing fuel efficiency. These standards continue to be discussed in the Transportation and Mobility industry.

Collaborate Effectively

None will do it alone. Today’s car OEMs are building new relationships with innovators in many new areas (apps, car sharing, service providers, urban transport). Transportation and Mobility suppliers are building expertise too, not only by collaborating with OEMs in innovative ways, but also by creating new networks of expertise by themselves. Our partnership with AKKA Technologies is a great example.

According to the IEEE (Institute of Electrical and Electronics Engineers), self-driving cars will account for up to 75% of cars on the road by 2040. These new vehicles and sophisticated systems management tools will speed up innovation and foster new collaborative networks in order to create new, secure and delightful autonomous driving experiences.

AKKA Link&Go 2.0

There are still many questions unanswered:

  • Why don’t we see more driverless cars in the streets?
  • Who will be faster to get autonomous cars on the road? Car manufacturers, innovative companies, government,…?
  • What is the future of self-driving cars?
  • What do you think about this revolution?

We are looking forward to your comments and suggestions!
