“Who puts speed breakers at traffic signals?Such unscientific measures are creating traffic bottlenecks artificially.First,remove speed breakers at junctions & fix potholes. Ensure there is no parking, street vending,or bus stops within a 75-metre radius of traffic signals" (1/2)

Some observations after riding a 2-Wheeler for 200kms in Bangkok. • Roads are smooth as butter. Never did I worry about looking at the ground for potholes while riding. • 4-5 speed breakers during the entire trip of 200kms that too on a service road. • No paver blocks. • 2-Wheelers violate traffic laws (Haven't seen a car/bus jump a signal). • Pedestrians are respected while they cross the road. • Hardly any traffic cops on roads to catch offenders or to manage traffic. • Road signs painted on roads clearly visible. • Zebra Crossing is respected and is visible too. • No random U-Turns. • No jaywalkers. • Cars need to wait for a clear road before entering the main road from bylanes/U-Turns. Vehicles going straight have priority. • Vehicles respect lane discipline and keep safe distance between two cars. • Tuk Tuk drivers are like our auto rickshaw drivers only, will ask for exorbitant fares for short distances. • There is wrong side driving here too by bike taxis, delivery boys but the number is far smaller than what we see in Mumbai. • Plenty of direction signs throughout the city to guide the motorists. • No multicolour dance bar type street lights. • Next to zero honking by vehicles. • No ugly birthday wishes to nagarsevaks/politicians on illegal banners over dividers. • No illegal hawkers on the footpaths. • Not enough dustbins across the city, but still it is way cleaner. Even public markets are clean. No pan tobacco spit stains. We are decades back to Bangkok in 2024. Hopefully we should reach their standards in the next 50 years.

The value of the work we're doing at Optimum is encapsulated quite well by the phrase "speed is money". In modern markets there are real economic advantages to latency reduction. This is nothing new. Wall Street firms have long been optimizing on latency, primarily through colocation and top of the line hardware. However, when it comes to decentralized systems, expensive hardware and geographic concentration are antithetical to their purpose. Therefore we should optimize decentralized network latency through software, which I'm thrilled about because it's exactly what I've spent the better part of the past 2 decades working on with Random Linear Network Coding. Now let’s talk about networking economics, the relationship between speed and money. First, it's important to note that users will only pay for low latency if it can be consistently guaranteed. Second, you can only make that latency guarantee for a certain number of users. This is a universal law of networking. We can model this relationship on a delay curve, shown below. The delay curve is determined by the utilization rate of the network, meaning how much traffic is flowing through the network divided by the network's throughput. As you approach a level of traffic equal to the available throughput, latency trends infinitely higher. On this delay curve we can impose some utility thresholds. These thresholds are the levels of latency which are important to different groups of users because of how that latency guarantee improves their economic outcomes. Finding the point on the curve where each threshold intersects will tell us what level of traffic we can guarantee that level of latency for. Essentially, there exists a finite supply of speed on a network and the highest utility users of that speed are willing to pay more for it. I like to think of this similarly to expedited shipping options on Amazon. This is why we say speed is money, and why we can create a Latency Marketplace. The only way to increase the supply of speed is to fundamentally increase network throughput. This is what we work on at Optimum by using Random Linear Network Coding. The same relationship between traffic and throughput still applies, but now the delay curve is shifted out further to the right. Now more traffic can be processed at the same latency, or the same traffic can be processed at a lower latency. More speed available to the network. More value unlocked for the network’s users. Crucially, that value is no longer only reserved for those who can afford to sit closest to the machine. Expanding the supply of speed widens who can reach each latency threshold, keeping the network's advantage decentralized rather than concentrated in the hands of a few. When nodes join Optimum and participate, they reap the benefits, but they also add to the capacity. Rather than vying against each other in a zero-sum game, nodes help themselves and others.
