Speed audits and driver-feedback signs that slow traffic outside schools
TL;DR Wardline measures how fast vehicles actually pass a school at drop-off and pick-up, puts up radar signs that show drivers their speed, and designs cheap street fixes. School chains and city corporations pay. Traffic police get the data, but issuing fines stays with them.
Road crashes killed 77,386 Indians under 18 between 2018 and 2022, and the yearly toll rose from 14,875 in 2021 to 16,443 in 2022, according to NCRB data compiled by CEE and UNICEF[1]. In Pune city, 33 of 343 road deaths in 2022 happened near schools, colleges or other educational institutions[1].
The legal speed past a school is already 25 km/h under the 2017 Rules of Road Regulations[2]. WRI India notes that this limit often isn't even signposted[3]. Does anyone measure compliance at the gate? Nobody does, so a principal who asks for a speed breaker walks in with stories and no numbers.
What it does, in regulatory terms: measurement, driver feedback and street-design advice only. It does not issue challans. Electronic enforcement belongs to State Governments under Section 136A of the Motor Vehicles Act and Rule 167A, which the Supreme Court told every state to implement in 2024[4].
That's why the seed got reframed. A private company can't run "AI enforcement", so Wardline does the part the police and corporations rarely have time for. A two-week radar audit records speeds at the gate by hour. Solar radar signs then flash each driver's speed during school hours, and a short report proposes fixes such as painted crossings, kerb extensions and waiting areas, ranked by cost. The school or ward gets a before-and-after speed chart every term, and traffic police get a list of hotspots for their own cameras.
Children and parents benefit, but the payer is an institution. Private school chains pay from their safety or CSR budgets, because parents ask about the school gate. Municipal corporations pay through road-safety budget lines - Mumbai set aside Rs 50 crore for safe school zones across 24 wards in its 2022 budget[5]. I found no public price for a school-zone audit in India, so working out the price is part of validation.
The Supreme Court's September 2024 direction on Section 136A[4] pushes states to put cameras where the risk is, which raises demand for hotspot data. District road safety committees in places like Pune now run child road-safety action plans that call for speed audits around schools[2]. Mumbai's pilot gave cities a local template to copy[5].
There's no public figure for India's school-zone safety market. The narrowest firm number is Mumbai's Rs 50 crore allocation for safe school zones across 24 wards[5]. The Pune action plan recommending speed audits around schools[2] shows the demand exists in policy, though not yet as a budget line in most cities.
WRI India runs the closest work - Mumbai's Byculla pilot with the city and traffic police, where kerb extensions cut speeds by 2–8 km/h[5], and a school-access mapping tool for Bengaluru[3]. CEE, RISE Infinity Foundation and UNICEF ran Pune's programme[1]. In the US, specialist makers sell radar speed signs for school zones[6]. These are mostly non-profits or foreign hardware makers. I found no Indian firm selling a priced, repeatable audit-and-signs service.

The radar and dashboard are simple. The slow part is permission, because every sign on a public road needs the road owner and traffic police to agree and that varies by city. Sales cycles with corporations follow budget years. Keeping solar signs working outdoors through monsoons, theft and dust is a field-service job that never ends.
Yes, this needs approvals. The radar is regulated equipment and every sign sits on a public road.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI pick who gets fined or treat it as enforcement. That stays with the state, and radar data has to be checked before anyone acts on it.

I like this for a founder with urban-planning or traffic-engineering experience who can work patiently with city officials. If you're hoping to sell enforcement software then it is a poor fit, since that market belongs to state governments and large integrators. Prove two things first - that one school chain will pay for audits across five campuses, and that speeds stay down after a term.
Plan for roughly ₹92 L–1.6 Cr, mostly radar signs, field staff and type approval testing.
Yes, radar signs need WPC type approval, and each sign needs permission from the road owner and traffic police.
Yes, radar signs are common in US school zones. Check your local radio equipment rules and who approves signs on public roads.
The free Wardline validation kit has the line-by-line capital breakdown, the effort scoring, the permissions and radio checklist, a 14-day validation sprint with pass/fail targets, a 90-day launch plan, 10 interview questions for schools and city officials, and 5 assumptions to test.

Thinking about building Wardline or something close to it? The make-or-break work is getting road owners and traffic police to approve signs quickly in your first city, and that's the kind of thing I help founders with. If you need a hand, you know where to find me. Talk to Yash →
