Stop the wave
before it starts.
FASTag Chain Reaction — the app that prevents toll-plaza traffic jams in India before they form.
The Problem
One stopped car. A wave that lasts minutes.
Stopped car at a toll booth — low balance, blacklisted tag, or scan failure.
Vehicles backed up within 90 seconds at peak hour on the Lakhanpur Toll plaza.
Of residual slowdown that propagates upstream long after the trigger clears.
Toll plazas on the Srinagar–Jammu corridor process thousands of vehicles per hour. When even one driver discovers their FASTag has insufficient balance at the boom barrier, the queue behind them doesn’t just pause — it compounds. A 12-second stop becomes a 3-minute wave.
The Chain Reaction
Traffic waves travel backward.
Wave propagates backward at ~20 km/h.
When a car stops, the car behind it has to brake harder, and the one behind that brakes harder still. The disturbance travels backward through traffic faster than the cars themselves can recover — basic shockwave theory. By the time the original driver pays and leaves, the queue 500m back is still growing.
The Solution
Prevent the trigger. Defuse the wave.
Four features that make sure no driver is the one who stops the boom barrier.
5 km location warning
GPS-aware alerts the moment you enter a toll geofence — Lakhanpur, Sarore, Bann, Lower Munda.
Cross-bank readiness
Checks balance, KYC status, and blacklist flags across every issuing bank — HDFC, ICICI, SBI, Paytm, IDFC.
One-tap UPI recharge
Top up from any UPI app in under 4 seconds — before you reach the boom barrier, not after.
Crowdsourced plaza health
Live wait times and scanner status reported by every driver in the network — the more users, the smarter the corridor.
