Corridor inventory at traffic speed: signs, markings and clearances without lane closures
Transport authorities need a complete, current inventory of the corridor: signs, lane markings, barriers, gantries, signals — and the clearances that govern what can pass through. The traditional way to get it involves crews on the carriageway, lane closures, and the risk and cost that come with both.
Drive-by capture removes the closure. A 360° camera and GPS ride on an ordinary vehicle moving with traffic, so the corridor is captured at traffic speed — no cones, no stopping, no exposure for a crew standing beside live lanes.
From that single pass:
- Signs and markings are detected and catalogued by the AI feature step, written as typed features into your GIS.
- Clearances and dimensions — bridge underclearance, gantry heights, lane widths — are measurable directly in the browser from the georeferenced point cloud.
- Condition and change are tracked drive-over-drive by automatic change detection, so a missing sign or a faded marking surfaces as a work order.
Because the deliverable is survey-grade and georeferenced, the inventory supports planning, maintenance and compliance from the same dataset — and it’s cheap enough to refresh, because it rides on a camera rather than a LiDAR truck.
It’s the same always-current twin that serves utilities and smart cities, focused on the corridor. See how it maps to the industries we serve.
