Mathematicians have solved traffic jams, and they're begging cities to listen

Math approaches to traffic

  • All drivers need to be on the same navigation system. Cars can only be efficiently rerouted if instructions come from the same hub. 
  • Many urban roads are too narrow. Traffic-flow models can indicate where parking spots should be turned into lanes.
  • Green lanes incentive. For cities that want to increase electric car use, special lanes should be created for electric cars.
  • Digital twins. Digital modeling can create an entire “twin” of existing roadways to assist transport engineers.

Key Ideas

Traffic jams 

Most traffic jams are unnecessary. Local transport engineers manage to achieve local improvements, but after a while the flows rearrange, and the same traffic jams appear elsewhere.

Mathematicians who specialize in traffic flow would like to solve urban traffic jams forever.

Effect Of Noise on Children
  • According to the United Nations, about two-thirds of the world's population will be living in cities by the next 30 years.
  • The World Health Organization recommends classrooms to be not louder than 35 decibels, which is never the case in big cities.
  • Children are facing disruption in their learning, and research points out that those who study in a noisy place are 11 months behind the ones who are studying in quieter places in the same vicinity.
Living In Noise

Most of the city planning is done so that the affluent neighborhoods are in quieter areas.

However, this is also nullified when the ultra-rich who travel frequently stay close to the transit hubs (like Airports), being exposed to high decibels of noise.

Innovation Capital

There are four factors how innovators build up their innovation capital: Who you are, who you know, what you have done, your ability to draw attention to your ideas. Most notably, innovation capital is something accumulated over time through thoughtful action.

The Cybertruck is then about getting attention and proving that Tesla is one of the world's most innovative companies, specifically for the purpose of building Tesla's ability to win support from stakeholders.

Winning the resources

Elon Musk is a master of building and using innovation capital to win support for his ideas. To gain support:

  • He leverages his past success at PayPal and Space X
  • He uses "impression amplifiers". He does more than talk about the new idea. He puts it into physical form to convince skeptics.
  • He broadcasts the idea through big media launches to generate a buzz.
  • He compares or draws a comparison between his innovation and some other successful one to create an impression of technical superiority.

Heuristics during periods of uncertainty

During periods of heightened uncertainty, leaders reflexively reduce investment, stop hiring, slash marketing, refrain from entering new markets, or stop making decisions.

Although understandable, acting in a pro-cyclical manner can be counterproductive. It can leave companies poorly positioned to benefit from the next stage of the cycle.

Attributes to succeed in uncertainty

Organizations should be inclined toward action. As a baseline, companies must strive to be fit for growth. This can be done by aligning costs with priorities and strategy, investing in varied capabilities, and using traditional and digital levers to execute.

They must regularly engage in scenario planning with an array of options. They must build the capacity to be agile. They must learn to become more resilient to withstand strong external forces and quickly recover from setbacks.
