Do more pedestrians avoid Houston's most dangerous roads?

No. The correlation between a corridor's crash-risk percentile and its observed pedestrian volume was r = 0.04, essentially none. High-risk corridors carried slightly more foot traffic than average, not less.

Are dangerous Houston arterials more congested than safe ones?

No, the opposite. Risk percentile correlated negatively with vehicle volume (r = −0.20). The most dangerous corridors carried less traffic than typical, consistent with wide, uncongested roads where nothing slows drivers down.

When is the most dangerous hour on a high-risk corridor?

8 PM, not the 6 PM pedestrian peak. Vehicle volume stays close to its afternoon level through 8 PM while pedestrian presence has already collapsed, pushing the vehicle-to-pedestrian ratio to its daily worst.

How was this data collected?

108 Houston TranStar public traffic cameras were read every 10 minutes for three weeks (July 3-23, 2026) and passed through a local YOLO11s object detector to count pedestrians, cyclists, and vehicles, at no cost.

How much less common is cycling than walking on these roads?

About 34 times less common. Average cyclist count per camera frame was 0.0005 versus 0.0175 for pedestrians, across all 108 arterial cameras.

Houston's most dangerous roads aren't empty.

Three weeks of free public traffic-camera footage across 108 Houston arterials, counted frame by frame. The corridors with the worst crash records carry as much foot traffic as any other, and less car traffic than average.
