SentinelEdge Traffic Dataset

A large-scale urban traffic dataset combining Bengaluru CCTV footage with the UA-DETRAC benchmark, assembled for the SentinelEdge traffic management and vehicle detection system. Contains ~196,000 annotated images across four sub-datasets covering Indian urban roads and international highway scenarios.

Sub-datasets

1. BMD-45-Train

• 35,792 images from 45 Bengaluru CCTV locations
• 373,132 bounding box annotations in COCO JSON format
• Covers mixed urban traffic including autos, two-wheelers, heavy vehicles

2. UVH-26-Train

• 17,387 images from 26 urban Bengaluru camera locations
• COCO JSON annotations (single-track and multi-view variants)
• High vehicle density, diverse lighting conditions

3. IITM-HeTra v2

• 2,836 images from IIT Madras Heterogeneous Traffic dataset
• Pascal VOC XML annotations
• Train/val/test splits provided via trainval.txt and test.txt

4. UA-DETRAC

• 140,131 images from 100 traffic sequences recorded in Beijing and Tianjin
• XML annotations with per-vehicle attributes (type, occlusion, truncation)
• Includes MOT evaluation toolkit
