🚨 MAJOR UPDATE on Bangalore Traffic Project!

I am confident of improving Bangalore traffic by 25-30% within a year's time

---

1. Collaboration at Scale

In just 10 days, after meeting the commissioners of BTP, BBMP, CP, Google team, IISC professors, Scientist, Road Engineers, Traffic Related Entrepreneurs. All three newly appointed commissioners were very kind to invite me to showcase existing capabilities AND collaborate to work together. For the first time we are bringing all key public and private players - to the same table.

2. Quick Optimization Projects

A) Bangalore Traffic Simulators
Both BTP and IISC have simulation models, which can create millions of re-routing permutations to reduce travel-time (not shortest distance). I have requested the data from Google, Uber, Ola, Rapido, that will make models predict better re-routing. Some of them have confirmed to help. Waiting for others. If the model starts working, we will be able to predict where/when gridlock is going to happen, so we can fix it before it occurs.

B) Fixing Feedback Loop
Govt already has apps, where people can report potholes. I will take ownership of that app, to increase its scope (report illegal parking, broken signal, wrong side driving, water logging, broken vehicle, etc). I will also increase accountability and recognition by showcasing all the complaints lodged AND action-taken (along with time-stamp) publicly.

C) Hyperlocal Rain Predictor
Govt closes the road to do infra/maintenance work, but then it starts raining on that patch of road and work halts. This leads to crazy downtime and traffic congestion. Hyperlocal Rain Predictor project will also allow us to fix drainage issues, even before it happens.

D) Green Wave Signals: Putting traffic lights in sync, so they move vehicles in waves, instead of stopping at every junction. A pilot is already happening, we will analyse the results to see if it makes sense to be done at City level.

3. The Vision for India

Many people mentioned in my last post "Bangalore Traffic is an Infra problem", congrats on stating the obvious. If we continue to wait for the infra to become better, then we are merely playing a catch-up game with the West. There is so much scope to optimize current infra, and I would rather focus on that. This is no longer about rants or blaming the system. It’s about practical optimism - believing that with data, intent, and collaboration, we can improve what feels unfixable.

4. Ask from Readers:

A) Continue your support and share/comment. The more you amplify, the more right folks will be able to join us in solving this gridlock. I am in it for the long haul. Are you?

B) Join our WhatsApp Community, where I will regularly post the next-steps. Plus we need more info from each one of you. On which junction/road, you face massive traffic issue. So we can present them to the right authorities. Link to join below in the comment section 👇

Why is this a red flag?

Be careful with using window.addEventListener("scroll",()=>{}) in React;

This can cause huge performance issue without proper knowledge.

Lazy Loading in Next

Next uses dynamic from 'next/dynamic' package

Under the hood, this dynamic function uses 'React.lazy. It's a replacement for it, and works exactly the same way.

With 'dynamic', we can pass a second argument for configuration. One of the config options is a loading component.

[Vijeth Simha @vijeth_simha]

When you create a Next.js project, you'll find a 'src' folder with 'layout.js' and 'page.js' files. By default, both 'layout.js' and 'page.js' are set up for server-side rendering (SSR).

[Vijeth Simha @vijeth_simha]

Lazy Loading

The idea of lazy loading is to defer loading the JavaScript code associated with a particular component until it's needed.

React uses via the React.lazy() method.

How does this work in Next?

In an SSR context, the first render happens on the server so Lazy loading has no effect on the server.

Lazy loading is explicitly about how our client-side JavaScript is split into different bundles.
