Adaptive Path Planning and Collision Avoidance for Autonomous Vehicles on Unstructured Indian Roads

MathWorks · Robotics and Drones · Software

The best-specified statement on the portal with named metrics and linked data, but it is also one of the most attractive and the scope is genuinely massive, so only take it if your team already knows MATLAB and RoadRunner and can spend the whole time on the prediction model rather than the tooling.

Open dataset ↗

Data: Built-in sensor and scenario datasets in MathWorks Automated Driving Toolbox, RoadRunner sample scenes, team-created synthetic scenarios, and public Indian traffic datasets. Indian Driving Dataset (IDD): https://idd.insaan.iiit.ac.in/ ; Mendeley traffic data.

What it actually is

Self-driving systems are built for roads with painted lanes, working signals and traffic that behaves predictably, and Indian roads are none of those things. Cars, auto-rickshaws, bicycles, pedestrians and cattle share the same space and move without warning. The ask is a simulated driving system that can plan a safe path through exactly that kind of chaos and replan the instant something changes.

What to build

A closed-loop simulation pipeline in MATLAB and Simulink with a perception stage fusing camera, LiDAR and radar to detect the mixed road users the statement names including auto-rickshaws, pushcarts, pedestrians and animals, a short-horizon motion prediction stage that handles non-lane-based and irregular trajectories rather than assuming lane-following, a planner producing collision-free paths without relying on lane geometry and replanning in real time, decision logic for informal merging and sudden obstacles, and a vehicle dynamics model closing the loop — validated across the five scenarios the statement mandates including an unmarked village road, an unsignalled urban intersection, a highway merge, a dense market and a cattle crossing, with at least two detailed RoadRunner scenes and results reported on replanning latency, path smoothness and scenario completion rate.

Smallest thing that wins the room

Run the cattle-crossing scenario live and show the planned trajectory re-forming around the animal with the replanning latency displayed on screen as it happens.

How crowded this one gets

A guess, projected from the 2025 statements — the last year where both the submission counts and the winners were published.

A normal-sized field. Your idea has to be good, not miraculous.

Why: company-sponsored statements drew the smallest fields of all.

This is a guess, not a fact

Nobody has published 2026’s numbers yet. This is an analysed estimate from last year’s pattern, so please do not take it as the truth — check the live counter on the SIH portal before you decide anything. The range covers the middle half of likely outcomes, so one statement in two lands outside it. Entry closes at 500 ideas per statement, so no range goes past that — a statement that reaches the cap fills and shuts rather than drawing an unlimited crowd. The model reads only three things a team can see before choosing — software or hardware, the theme, and what kind of body posted it — and those explain about a quarter of the variation in last year’s field sizes (R² 0.25 on held-out statements). Trust the band more than the number, and the ordering more than either. It cannot see how good your idea is, which is the part that actually decides it.

The number is the shorthand. The line under it is the reason.
