In the Field
Case Studies
LAccMI — Rural Odisha, 1,900+ buses, zero connectivity
How Chartr built a fully offline AFCS for Odisha's rural bus network — 2.5 lakh tickets a day, no live internet required, 2,000+ conductors trained in under 2 weeks.
More case studies coming
Delhi, Pune, Rajkot and more. Reach out if you'd like to know how Chartr performs in a specific context.

News Coverage
IIIT-Delhi's Chartr app eases bus commute in Delhi
Chartr's 'transport stack' supports tracking, journey planning, and multimodal ticketing, deployed across DTC and Cluster buses to improve citizen mobility experience at scale in Delhi.
IIIT-Delhi Startup Chartr Set to Expand Nationwide
Covers Chartr's journey from 7+ years of urban mobility R&D at IIIT-Delhi into a deployed real-world mobility platform, now scaling across Indian cities.
Chartr Completes Full Technology Transfer from IIIT-Delhi
A milestone in academic entrepreneurship — full technology transfer from IIIT-Delhi to Chartr, recognizing years of work on public systems optimization.
Delhi Govt + IIIT-Delhi Mobility Collaboration
Coverage of Delhi's transport department working with Chartr during government-backed mobility pilot programs, highlighting how Chartr was used in real policy experimentation.
Pune
Apli PMPML — The App People Love
Apli PMPML — Official App
Digital ticketing, live bus tracking, metro tickets & passes for Pune commuters. Built on Chartr's full transit stack.
1 Lakh Downloads in Just Over a Week
Apli PMPML hits 1 lakh downloads in its first week — digital ticketing and metro integration praised, with high public engagement immediately after launch.
Apli PMPML App to Help Passengers Track Buses and Book Tickets
Launch coverage highlighting live tracking, bus routes, digital tickets and passes, complaint center, and metro integration all in one app for Pune commuters.
PMPML's Real Ticket to Success Lies in Integrated Approach
In-depth look at how the Apli PMPML digital stack is central to Pune commuter discussions and the future of integrated transit in the city.
Founder
Pravesh Biyani — Interviews & Conversations
Founder & Associate Professor, IIIT-Delhi
Pravesh Biyani
Researcher, entrepreneur, and public transport advocate. 7+ years building urban mobility systems at IIIT-Delhi, now scaling Chartr across India. Writes and speaks extensively on why public transport matters and how technology can make it work.
"We need more buses, reforms in tendering and procurement processes"
A major interview in The Hindu where Pravesh Biyani makes the case for systemic reform in Delhi's bus procurement — arguing that technology alone can't fix public transport without the right policy foundations.
Athera Odyssey: Deep Dive into Chartr
An insightful interview with Pravesh Biyani featured by IIIT-Delhi — covering the startup journey, academic roots, and the vision for public transport technology.
Why Tech Billionaires Suck at Fixing Transport
A widely discussed post on why congestion, sustainability, and mobility are harder than Silicon Valley makes them look — and what actually works.
Solving Urban Mobility: A Complex Economics Issue
Discussion on public transit adoption, last-mile realities, and why urban mobility is fundamentally an economic coordination problem.
Using Bus Ticket Data to Predict Traffic
An interesting public transport data science insight — how ticketing data reveals traffic patterns before they appear on maps.
Pan-India Bus Feature Announcement
Announcing a nationwide Chartr public transit feature — a key milestone in scaling the platform beyond Delhi to all partner cities.
Academic
Research Behind the Platform
Over 7 years of peer-reviewed research at IIIT-Delhi directly translated into Chartr's products. These papers are the science behind what Chartr ships.
Published at IEEE ITSC, IEEE T-ITS, and COMSNETS — top venues for intelligent transportation systems research.
No Transfers Required: Integrating Last Mile with Public Transit Using Opti-Mile
Raashid Altaf, Pravesh Biyani
Only 30% of Delhi bus/metro stops are directly reachable on foot — Opti-Mile solves this by combining last-mile services (rickshaws, shuttles) with public transit into a single trip plan. The research behind Chartr's multimodal journey planning.
Stochastic Trip Planning in High Dimensional Public Transit Network
Raashid Altaf, Pravesh Biyani
Uses Gaussian Processes to find optimal routes across Delhi's combined bus and metro network in real time. Choosing stochastic shortest paths over deterministic saves up to 40% travel time. The algorithm behind Chartr's trip planner.
Traffic Estimation and Prediction via Online Variational Bayesian Subspace Filtering
Pravesh Biyani et al.
Published in IEEE Transactions on Intelligent Transportation Systems — Chartr's traffic prediction methodology for computing reliable ETAs even in the absence of dense sensor data.
Demo Abstract: Contactless E-ticketing in Public Transport Buses
Rajan Girsa, Kshitij Srivastava, Atul Jain, Pravesh Biyani
Presented at COMSNETS 2021 — the academic paper behind Chartr's contactless ticketing product, demonstrating fare collection without physical contact, relevant post-pandemic for Indian buses.
Benchmark Dataset for Timetable Optimization of Bus Routes in New Delhi
Pravesh Biyani et al.
Real-time GPS data for 500+ Delhi bus routes with a timetable optimisation algorithm. The foundational data infrastructure work that preceded Chartr's AVLS, scheduling, and open GTFS dataset.
To Each Route Its Own ETA: A Generative Modeling Framework for ETA Prediction
Charul, Pravesh Biyani
The research behind Chartr's bus ETA system. Works without large historical datasets, handles outliers and incomplete GPS data — exactly the challenge in Indian cities where infrastructure is sparse.
Improved Real Time Ride Sharing via Graph Coloring
Saatvik Jain, Pravesh Biyani
Real-time ride sharing optimisation using graph coloring algorithms — related to last-mile integration and the efficient pooling logic in multimodal transit planning.
TrafficKarma: Estimating Effective Traffic Indicators
Kireet Pant, Dibyendu Talukdar, Pravesh Biyani
The earliest transport work — using public data to monitor and visualise city traffic patterns. Won 2nd runner-up at the CODS Data Challenge, Bangalore 2015. The origin of Chartr's data-driven approach to urban mobility.
