Energy security · Urban economics · National reform
While geopolitical shocks in West Asia threaten India's energy supply, we quietly waste hundreds of crore rupees in fuel every single day. Not from driving. From not moving. This is not a traffic problem. It is a national economic haemorrhage with a known cure.
You have been there. Engine running. Light red. The signal has been red for 90 seconds. Cars behind you start honking. The auto beside you revs unnecessarily. The truck ahead belches black smoke. You sit there, burning fuel, burning time, burning patience. Going nowhere.
Now multiply that moment by 350 million vehicles. Across 50 cities. Every single day.
That is not a traffic inconvenience. That is a fiscal emergency. One that India has been treating as a municipal nuisance for decades while paying foreign nations to fuel the chaos.
The moment that changes everything
In early 2026, US and Israeli strikes on Iran sent Brent crude up 7.4% overnight. India, which imports nearly 90% of its crude and routes close to half of it through the Strait of Hormuz, watched its energy bill surge. HDFC Bank warned that a sustained $10 per barrel rise widens India's current account deficit by 40 to 50 basis points. PM Modi appealed to Indians to reduce fuel consumption. The appeal was genuine and necessary. But the conversation skipped the most immediately actionable lever available. We are burning imported oil by the millions of litres every day in vehicles that are not moving. Fix that first.

The idle fuel crisis: known since 1996, ignored ever since
Here is something that should infuriate every Indian policymaker. In 1996, nearly three decades ago, the Central Road Research Institute (CRRI) published a formal study measuring fuel burned by vehicles idling at traffic signals in Delhi. The findings: over 4,22,000 litres of petrol and diesel wasted every day at Delhi's signals alone. The annual cost, at 1996 fuel prices, was Rs 245 crore. For one city.
What the research trail actually shows
The CRRI finding was not an anomaly. Subsequent peer-reviewed studies across Indian cities, including Indore, Chandigarh, Agartala, Chennai, and Ahmedabad, all found the same pattern: massive, measurable fuel waste at signalised intersections, with 95 to 100% of drivers keeping engines running through red lights.
A 2018 peer-reviewed study at eleven Delhi intersections (Transportation Research Part D) found daily losses of over 9,000 litres of petrol and diesel combined. A separate study of just two Chandigarh intersections found fuel loss running at Rs 2.4 crore per year per junction.
The research has been consistent for 26 years. The policy response has been nearly nonexistent. India's vehicle population has grown from under 50 million in 1996 to 350 million today. A 7x increase. The idle fuel waste has scaled accordingly. We simply stopped measuring it as urgently as we should have.
There is no single current national estimate because nobody in government has commissioned one at scale. That absence is itself the story. We track our forex reserves to the dollar. We track inflation to two decimal places. We have never formally calculated, at national scale, how many billions of dollars of imported crude we burn annually at red lights. The moment someone does that calculation officially, it becomes politically impossible to ignore.
"India is paying foreign nations for the privilege of sitting in traffic. We have known this for 26 years. We have done almost nothing."
Why we keep building flyovers and the traffic keeps getting worse
There is a law in traffic engineering called Braess's Paradox. Adding road capacity to a congested network can actually worsen traffic, because new roads generate new demand. We build a flyover. People who previously avoided the route now use it. Within three years it is as congested as before. We build another flyover.
This has played out in Bengaluru, Hyderabad, and Mumbai for thirty years. The solution is not less infrastructure. It is the right kind of intervention. And the right interventions do not all require concrete.
Picture this: your morning, designed for failure
You leave home at 8:45 AM. First signal: red for 90 seconds. The timing was set in 2019 and never updated. You move 200 metres. Another red, though that road is empty. A food cart occupies the left-turn lane at the main crossing, forcing all traffic into a single lane. You cover 5 km in 35 minutes. At your destination, the metro station has no bus. The bus left 4 minutes before you arrived. The next one is in 22 minutes. You will not take the metro tomorrow.
Every inefficiency in that journey is designed in. None of it is inevitable. All of it is solvable, without a single new road being built.
What works. With proof from Indian roads.
The mistake in every smart-city conversation is jumping to AI before clearing the drains. Here is what actually needs to happen, ordered by what evidence already exists on Indian roads.
Start here: Junction surgery, no technology needed
Every major Indian city has 20 to 50 junctions responsible for a disproportionate share of its congestion. Map them. Clear the encroachments. Relocate the bus stop blocking the merge lane. Add the lane marking. Issue the work order. Enforce it.
Traffic engineering research consistently shows that a small number of point failures, poorly designed junctions and illegal encroachments at chokepoints, are responsible for the majority of urban delay. These require no new infrastructure, only enforcement authority and political will.
Proven and ready to scale: Bengaluru's AI traffic experiment
In May 2024, Bengaluru launched the Bengaluru Adaptive Traffic Control System (BATCS): 165 AI-powered junctions using indigenously developed software from C-DAC, with green wave corridors synchronised in real time. By early 2025, results were in.
15 to 20% reduction in travel time across covered corridors. 16 to 61% increase in average speeds on specific central stretches. 20% improvement in corridor throughput. 10% drop in estimated emissions. Over 56% of surveyed commuters reported a measurably smoother experience. Source: Deccan Herald, Bengaluru Traffic Police, 2025. The system is now expanding to 500 junctions. This is not a pilot. It is proof.
Replicate now: Pune's Google-backed Trafficure system
Launched in February 2026 in partnership with Google India, the Trafficure system divides Pune into 550 real-time traffic monitoring zones, with signal timing adjusted from live Google Maps data.
Early trial data: average speeds improved from 20 kmph to 26.8 kmph. A 34% increase. Pune is the third-most congested city in Asia. A 34% speed improvement means proportionally less idle fuel burn, fewer vehicles on road at peak, and lower emissions. This experiment is live in India, on Indian roads, using Indian traffic data. It has not been replicated in a single other city. That is a policy failure, not a technology gap.
The missing link: the metro-bus handshake
India's metros are engineering achievements stranded by a coordination failure. When a metro arrives at a station, the connecting bus has often already left. The next one comes in 20 minutes. The rational commuter buys a two-wheeler. Repeat across millions of households and you have the primary driver of private vehicle proliferation in Indian cities. Not preference for private vehicles. A rational response to an unreliable alternative.
The fix: mandate every metro authority and city bus corporation to share live scheduling APIs. Build one app where metro arrivals are connected to bus departures at exit gates. If a metro is delayed 8 minutes, the feeder bus waits 8 minutes. Helsinki's MaaS system achieved measurable modal shift away from private vehicles within 18 months. The technology exists. The barrier is a government order for two agencies to share data.
Structural shift: make smooth driving financially rewarding
Usage-based motor insurance links your premium to how aggressively you drive. Calmer, smoother drivers pay less. Already live in the UK, Italy, and the US. IRDAI issued a framework for it in India. Adoption is negligible. Make it the default option at new vehicle registration.
Stop-start aggressive driving burns 20 to 30% more fuel per kilometre than smooth driving at the same average speed. No fiscal cost to government. The market does the behaviour change work. Aggressive driving becomes expensive. Smooth driving becomes rewarding.
The accountability gap that kills every reform
Well-intentioned traffic reforms die in India for one consistent reason: the system asks citizens to change behaviour while delivering nothing in return. Roads stay broken for months. Signals malfunction and nobody fixes them. Encroachments return within 30 days of clearance. The rational citizen response is disengagement. Why follow lane discipline in a system that does not maintain lanes?
Every city that launches a traffic reform programme must publish a live dashboard. Not a quarterly PDF. A URL, updated daily: junction speeds, signal uptime, last-mile wait times, complaint response times. When Delhi's air quality data became visible in real time, it changed political behaviour overnight. Visible government performance creates accountability that no audit committee can replicate.
And let us be honest about what Indians are actually capable of. UPI transformed payment behaviour for 400 million people in 36 months. Kumbh Mela manages 40 million people with extraordinary coordination. Swachh Bharat changed how cleanliness is discussed publicly. The common thread: the environment was designed for compliance, and compliance was made visible and rewarding. Traffic is the one domain where India designed chaos and then blamed the commuter.
"Indians do not lack civic sense. India lacks civic system design."
The political opportunity hiding in plain sight
Every intervention above is visible, attributable, and fast-acting. A commuter who saves 25 minutes daily knows exactly why. A family whose petrol bill drops notices immediately. This is not like fiscal consolidation or monetary policy, where benefits are diffuse and nobody knows whom to thank. Traffic improvement is personal, daily, and unmistakable.
PM Modi's call to reduce fuel dependence is correct and urgent. The fastest path to meaningful reduction is not waiting for EV penetration to cross 30%, which is a decade away at current adoption rates. It is closing the daily haemorrhage on existing roads, with existing vehicles, using interventions already proven in Indian cities. Three targets that would make this real:
Average urban speed above 25 kmph in India's 20 largest cities by December 2027.
Last-mile transit wait time under 8 minutes at every metro station by March 2027.
A formal, government-commissioned national estimate of urban idle fuel waste, published within 6 months.
That last one costs almost nothing. And the number it produces will be so large, so concrete, and so undeniable that it will do more for urban transport reform than any smart city budget line ever has.
The bottom line
India spends roughly $150 billion a year on imported crude. Every $10 per barrel rise adds approximately Rs 1 lakh crore to that bill. We control nothing that happens in Tehran or Tel Aviv. We control everything about whether a bus stop is illegally placed in a merge lane in Baner. We control everything about whether Bengaluru's proven ATCS system gets mandated in Hyderabad, Chennai, and Ahmedabad. We control everything about whether metro and bus schedules are finally coordinated.
The fixes are not glamorous. They do not require satellite imagery or billion-dollar command centres. They require a work order, a coordination meeting between two government departments, and a political leader who decides that the daily suffering of 100 million urban commuters is a national economic priority, not a local municipal complaint.
We have known about this problem since 1996. We have proof it is solvable, from our own roads, our own cities, our own engineers. The only thing missing is the decision that it matters enough to act on.
That decision is now overdue.
