Planned by hand
Bandobast strength is set from experience and last year's paperwork, not from a forecast of this event at this venue at this hour.

34,000 people arrive at Chinnaswamy in ninety minutes. 9 junctions fail.
ASTraM forecasts which junctions choke, when, and by how much — then writes the bandobast order that prevents it.

What happens today
No junction-level view
Congestion is known to be coming, but not which of the 28 junctions around a venue will exceed capacity, or in what order.
No costed counterfactual
There is no figure for what doing nothing costs, so deployment competes for resources without an argument.
How it works
Eight deterministic stages. No model artifact, no inference call — identical inputs always produce an identical, auditable order.
- 01
Seasonality
IPL outside April–May scales to a domestic baseline; June–August adds a monsoon delay multiplier.
- 02
Crowd to vehicles
Attendance becomes vehicle count at 2.5 occupancy, scaled by the event's vehicle ratio.
- 03
Spatial selection
A Haversine sweep selects junctions inside an impact radius that widens with turnout.
- 04
Per-junction load
Event traffic decays exponentially with distance and meets the hour's baseline road load.
- 05
BPR delay
A Bureau of Public Roads volume-delay curve, recalibrated to α 0.9 / β 4.5 for Indian mixed traffic.
- 06
Counterfactual
Signal override, constable presence and diversions are priced as a delay reduction, capped at 60%.
- 07
Severity and staffing
Capacity and delay combine into a four-level severity that sets extra constables per junction.
- 08
Order and economics
The result becomes a bandobast order and a costed comparison against doing nothing.
What it produces
Bandobast order
Shift windows, per-junction constable assignments, barricade types and locations, signal overrides and diversion routes — grouped by division with the responsible inspector named.
Dispatch brief
The same order compressed into a low-bandwidth WhatsApp message for constables in the field.
Cost of inaction
Fuel, productivity, delivery SLA and emergency response priced with and without deployment, with the ROI of the intervention.
