The Line is a scheduled city in Saudi Arabia, developed to be a 170 km long, 200 meters large, and 500 meters high string of high-rise buildings with a population density ten times that of Manhattan. Scientists from the Complexity Science Hub argue that its direct style is ineffective, hindering active movement and requiring a high-speed rail system that would still result in longer commutes than in other major cities.

In October, the excavation work for the superlative building and construction job started. While some view it as a best example of an environment-friendly urban area, others dismiss it as a simple publicity stunt. Now, scientists from the Complexity Science Hub show the reasons that The Line must not act as a model for the cities of tomorrow.
” Its the embodiment of the dream to start from scratch and entirely reconsider a city,” says Rafael Prieto-Curiel, who looks into cities at the Complexity Science Hub. The Line is planned to be a city developed from nothing in the desert. It is to include 2 gigantic, unbroken rows of skyscrapers, with living space in between. 170 kilometers long. 200 meters broad. 500 meters high, higher than any structure in Europe, Africa, and Latin America. String directly ahead from the Red Sea to the east.
10 Times Denser Than Manhattan
Nine million people are expected to live in it– more than in any other city in Saudi Arabia. This translates into a population density of 265,000 people per square kilometer– 10 times denser than Manhattan and 4 times denser than the inner districts of Manila, currently estimated to be the densest city areas in the world. “How you can bring in that lots of people in a medium-sized country at all is yet to be observed,” Prieto-Curiel points out.

Sixty Minutes for a Trip
Further questions emerge in terms of mobility. “A line is the least effective possible shape of a city,” says Prieto-Curiel. “Theres a reason that humanity has 50,000 cities, and all of them are somehow round,” he emphasizes.
In Johannesburg, which is 50 times bigger in area, 2 random people are just 33 kilometers apart. This prevents active mobility, so individuals will depend on public transportation.
As an outcome, trains spend significant time in stations and will not be able to reach high travel speeds in between any 2 stations. Even with extra reveal lines, gains are limited due to the additional transfers required. The outcome is that people would still be taking a trip longer than in other significant cities, such as Seoul, where 25 million people commute for less than 50 minutes.

A City Is More Than a Neighbourhood
Research shows that people wish to invest a limited quantity of time travelling, so effective transportation plays an essential role in the success of cities. Can these journeys through the city be avoided because high density allows whatever (jobs, shopping, amenities, and so on) to be available in your area? “Cities are more than a collection of semi-isolated 15-minute neighborhoods located next to each other. What sets a city apart from smaller settlements is not just its size however extra opportunities outside the instant neighborhood– such as concerts or a prolonged task search. For this factor, we need to think about citywide transportation,” discusses Kondor.
Why Not “The Circle”?
If you take The Line and make it The Circle with a radius of 3.3 kilometers, the range in between any two individuals would be only 2.9 kilometers, and 24% of the population would be within walking range of each other. A lot of movement might be active (walking, biking, or similar), making a high-speed rail system unnecessary. Alternatively, The Circle could permit excellent connection even with lower densities, preventing the requirement for supertall buildings.
Exists Something Positive?
” This job gets individuals discussing metropolitan forms, whichs tremendously important since cities, especially in Africa, are growing,” states Prieto-Curiel. Historically, cities typically grew in organic ways, while prepared cities often did not live up to expectations; thus, there is a requirement for more public engagement in metropolitan style on a human scale.
In addition, sustainability is stressed in lots of aspects of the task. For instance, there will be no automobiles for ranges that are no more than a five-minute walk. This not only saves a great deal of area in terms of infrastructure and parking but likewise reduces the variety of vehicles. All energy will be produced with zero carbon emissions. What is not taken into account here, however, is the construction of the high-rise buildings, which requires a lot of product and energy.
” Overall, it stands to reason that other factors to consider may have contributed in picking this distinct form, such as branding or creating interesting social media videos. It is crucial to understand the consequences, especially if The Line is dealt with as a showcase for modern building and urban preparation innovations”, stresses Prieto-Curiel.

The Line is an organized city in Saudi Arabia, designed to be a 170 km long, 200 meters broad, and 500 meters high string of skyscrapers with a population density ten times that of Manhattan. Now, scientists from the Complexity Science Hub demonstrate the factors why The Line should not serve as a design for the cities of tomorrow.
“A line is the least efficient possible shape of a city,” says Prieto-Curiel. The outcome is that individuals would still be taking a trip longer than in other major cities, such as Seoul, where 25 million people commute for less than 50 minutes.
