# DRINF: Dhaka Road Intersection Nadir Footage

## Overview

**DRINF (Dhaka Road Intersection Nadir Footage)** is a large-scale drone-based traffic dataset containing nadir (top-down) videos of road intersections across **Dhaka, Bangladesh**.

The dataset is intended to support research in:

- Vehicle detection
- Multi-object tracking
- Traffic flow analysis
- Vehicle trajectory extraction
- Trajectory prediction
- Surrogate safety analysis
- Intelligent Transportation Systems (ITS)
- Computer vision
- Machine learning
- Autonomous driving research
- Urban traffic analytics

The videos are captured using a DJI drone under real-world traffic conditions.
