Our work is the first to reach real-time on embedded devices while maintaining state-of-the-art level performance on the `BDD100K `dataset. + +* We design the ablative experiments to verify the effectiveness of our multi-tasking scheme. It is proved that the three tasks can be learned jointly without tedious alternating optimization. + + + +### Results + +#### Traffic Object Detection Result + +| Model | Recall(%) | mAP50(%) | Speed(fps) | +| -------------- | --------- | -------- | ---------- | +| `Multinet` | 81.3 | 60.2 | 8.6 | +| `DLT-Net` | 89.4 | 68.4 | 9.3 | +| `Faster R-CNN` | 77.2 | 55.6 | 5.3 | +| `YOLOv5s` | 86.8 | 77.2 | 82 | +| `YOLOP(ours)` | 89.2 | 76.5 | 41 | +#### Drivable Area Segmentation Result + +| Model | mIOU(%) | Speed(fps) | +| ------------- | ------- | ---------- | +| `Multinet` | 71.6 | 8.6 | +| `DLT-Net` | 71.3 | 9.3 | +| `PSPNet` | 89.6 | 11.1 | +| `YOLOP(ours)` | 91.5 | 41 | + +#### Lane Detection Result: + +| Model | mIOU(%) | IOU(%) | +| ------------- | ------- | ------ | +| `ENet` | 34.12 | 14.64 | +| `SCNN` | 35.79 | 15.84 | +| `ENet-SAD` | 36.56 | 16.02 | +| `YOLOP(ours)` | 70.50 | 26.20 | + +#### Ablation Studies 1: End-to-end v.s.
