Cities are complex and highly dynamic creations. They have living, breathing.
Think about all parts: millions of people, schools, offices, shops, parks, public services, hospitals, housing and transport systems.
The change & # 39; one aspect affects many others. That is why work is so complicated urban planner.
Imagine that you now have a tool at your disposal that you & # 39; answer questions like: "X & # 39; will happen with traffic and flow of pedestrians if be placing a new metro station in & # 39; this -Post? " or "How can we convince more people to leave their cars at home to go to work?"
This is where programs for modeling in 3D come into force.
Architects, engineers, construction companies and planners cities have used with computer-aided design and software modeling & # 39; information on buildings (BIM) to help create, plan and build their -multi.
But with the Internet advent of Things (IoT), sensors, Big Data and cloud computing, can now create digital "twins" of & # 39; whole cities that appear and act in & # 39; variety & # 39; different scenarios.
"Digital Town is a virtual representation of & # 39; building and physical resources, but all of them are connected with the data and information & # 39; those elements," explains Michael Jansen, executive director & # 39; Cityzenith, the firm behind the platform & # 39; Smart World Pro simulation.
"B & # 39; this way, learning machines and algorithms & # 39; artificial intelligence can be applied to help them operate with & # 39; most efficient way."
Take Singapore as an example.
State island, located at the bottom of the Malaysia peninsula and b & # 39; & # 39 population, six million people, now has a virtual digital twinning of the entire city created by & # 39; software developed by Dassault Systemes, a French firm.
"Virtual Singapore (virtual Singapore) is a digital twinning & # 39; Singapore based on topographic data and also on dynamic data in & # 39; real time," says George Loh, director of programs at the National Research Foundation (NRF ). English), government department.
"It will be authorized platform country can & # 39; used by urban planner to simulate testing & # 39; & # 39 into innovative solutions, virtual environments."
In addition to the usual map and terrain data, the platform incorporates traffic maps in real time, as well as demographic and climate data, says Loh. This allows urban planners trying to "virtual experiment".
"For example, we plan sections of barriers to persons with & # 39; disabled and elderly."
Bernard Charles, CEO of Dassault Systemes, says that the increase of data in real time on multiple platforms facilitate common and holistic thinking.
"The problem is that when deciding about the evolution of & # 39; city we are blind, with & # 39; a certain way," adds Charles.
"You urban vision – map – and decide to put in building & # 39; a certain area, but another agency must think about transport, and other agency in the business and in apartments for people."
"Creating & # 39; one change many others, like the flow of life of citizens".
The 3DExperience platform developed by his firm offers planners and designers "global vision" that never had before, explains Charles.
Dassault software, incorporating calculations simulating the flow of & # 39; liquid, used to design many of the cars and Formula One aircraft, says Charles, and his abilities be used to understand how the wind moves around buildings, roads and green spaces.
"If some parts of & # 39; too cold and windy city, no one wants to go," he says.
The monitoring of people's movements around the city using the & # 39; anonymous mobile phones and GPS data can & # 39; help authorities detect traffic jams and heat maps as the day progresses & # 39; forward.
The idea is that it makes it possible to create & # 39; transit management and more integrated transport systems.
"You & # 39; x analyze all possible scenarios, so if you ask the right question, you & # 39; to change the city, you & # 39; to change the world", concludes Charles.
In the state & # 39; Andhra Prades in India, "smart city" a new & # 39; US $ 6.5 billion called Amaravati was planned from 2015, but raised some controversy due to lack of & # 39; agreement on the design and criticism of its environmental impact.
The last year Foster + Partner, the architecture firm and global engineering, and Jurong Surbana, Asian advice on urban planning and infrastructure, have been selected to perform the task.
And Cityzenith, based in Chicago, USA, is providing the only digital platform "command and control" for the entire project.
Smart sensors will monitor the construction progress in real time, says Jansen, and the software will integrate all designs. There are about 30 advisers who are already involved in the first phase of the project.
"The portal will stimulate the impact of & # 39; those proposed building before starting construction," he says, "and simulations to adjust to changes in real-time."
The platform can & # 39; incorporates over a thousand database, according to Jansen, and integrate designs and tools & # 39; all planning used by designers and contractors.
The city, which will live about 3.5 million people potentially will be very warm and humid, with & # 39; temperatures closer to 50 ° C. Therefore, simulation & # 39; and building weather-resistant can & # 39; is crucial, adds the specialist.
Playing for design
large engineering consultancy in Norway, Norconsult, are combining simulation software to games to improve their designs.
For an ambitious project & # 39; rail tunnel in Norway, the firm developed a game & # 39; virtual reality that Vritual Singapore train drivers involved in the design of the & # 39; signaling system. Drivers' immaniġġjaw "virtual train from the tunnel, and warn of any problems with the proposed signal position.
"The weather conditions, speed and other things can change," says Thomas Angeltveit, who worked on the project. "It's true and it's much easier for them to interact."
"We have received many comments, so we could change the design and make many adjustments."
The modification of the design before its construction permit, without a doubt, to save in the long run.
The digital twins software is rapidly growing business, with firms such as Siemens, Microsoft and GE to add Dassault Systemes and Cityzenith.
The company is the market research Gartner estimates that by 2021, half of the large industrial companies will use digital twins, which can save up to 25% in operating costs.
The future is virtual design and, apparently, is driven by data.
