The paper introduces a geo‑referenced smartphone dashcam dataset of 63,839 frames from South Texas and a baseline framework for assessing road lane quality. Three new metrics—Contrast Stability Index (CSI), Line Continuity Ratio (LCR), and Regression Lane Confidence Score (RLCS)—are proposed to evaluate lane‑marking visibility, continuity, and map consistency without dense human labels. Baseline models achieve strong performance, and pilot validation shows the metrics correlate better with human judgments than generic image‑quality measures.

Lane detection requires recovering thin, elongated, and frequently occluded lane structures under challenging driving conditions. While anchor-based detectors provide efficient candidate generation, their performance is limited by two coupled issues: backbone features often lose structural continuity along partially visible lanes, and classification confidence may decouple from line-level localization quality, allowing inaccurate anchors to persist before non-maximum suppression (NMS).

The paper introduces the Lane Field, a dense bird‑eye‑view (BEV) geometric representation that captures local lane structure at each spatial location. This representation can be predicted from onboard data or derived from external map priors, and is used in a plug‑and‑play framework that modulates BEV features and guides deformable attention toward lane geometry. Experiments on OpenLane‑V2 demonstrate that these mechanisms consistently improve existing online HD mapping methods, achieving state‑of‑the‑art performance on lane segment perception.

TrafficImag is the first benchmark designed to evaluate counterfactual roadside traffic video generation, combining a large roadside dataset with an executable protocol that supports behavior reasoning, intervention-aware image editing, and conditional video generation. Each intervention is encoded as an actor-level program specifying target actor, intended behavior, legal route, interaction order, and temporal constraints, allowing a unified evaluation across diverse foundation models. The benchmark assesses four validity dimensions—initial-state correctness, route and behavior validity, interaction consistency, and non-target preservation—and reports that the best models achieve 80.4% macro F1 for reasoning and 55.0% end-to-end success when using a complete condition interface.
The paper introduces an edge‑assisted crowdsensing framework that uses handlebar‑mounted cameras to capture street‑level video, a vision‑language model to extract structured traffic attributes, and an explainable boosting machine to combine these with OpenStreetMap data and on‑bike kinematics for a 1‑9 safety score. On 1,362 annotated frames from two London routes, the model achieves 72.2 % binary accuracy and a mean absolute error of 1.011, with feature attribution revealing the impact of lane separation, painted lanes, and construction sites on safety ratings. The system operates efficiently at the network edge, requiring only 2.49 s per frame for extraction and 0.4 ms for scoring, and supports continuous monitoring at a cost of 1.4 accuracy points for 1,000 riders over a 20‑second interval.
The paper introduces a multi‑modal traffic sign detection framework that fuses camera and LiDAR data using an Intensity‑Aware Deformable Fusion module to align retro‑reflective LiDAR cues with visual features. It also presents a dual motion‑model tracker to handle non‑linear perspective changes and a semantic attribute classification pipeline that estimates occlusion, readability, sign embeddedness, and road relevance. Evaluated on a dataset covering more than 60 countries and 2,500 hours of driving, the system achieves an Object Miss Ratio of 0.49% across 221,068 sequences, indicating strong global generalization for autonomous driving.
