LiDAR Route Surveys at Highway Speed

How a LiDAR route survey works

Traditional route surveys stop traffic and measure each structure with a height pole or handheld device — one bridge at a time, one lane at a time. A MeasurePRO LiDAR route survey replaces that with continuous capture: the 2D LiDAR scanner sweeps the space above the vehicle, measuring bridges, overhead wires, traffic signals, sign gantries, and tree canopy with ±2 mm accuracy across a 0.2–250 m range, all without leaving the driver's seat.

Every measurement is stamped with dual-GPS position and paired with a synchronized camera frame, so each clearance value can be traced back to exactly what the sensor saw and where. The result is a complete vertical profile of the route — not a handful of spot checks.

The same field method applies globally across oversize/overweight and OS/OW heavy haul, abnormal loads and exceptional transport, and project cargo or out-of-gauge (OOG) corridor assessment. MeasurePRO gives organizations that conduct their own route reconnaissance a consistent capture process from highway segments to remote final-mile access.

Why teams switch to LiDAR surveying

• Speed: survey a full corridor in one drive instead of days of stop-and-measure work.
• Safety: no crews standing in live traffic lanes with height poles.
• Completeness: continuous scanning catches the low wire between bridges that a spot survey misses.
• Evidence: synchronized camera capture makes every reading defensible in permit applications and disputes.
• Repeatability: re-drive the route after construction or resurfacing and compare profiles.

From drive to deliverable

MeasurePRO works fully offline in the field. Back online, surveys sync to the RoadScope platform where the route profile is analyzed against planned load heights and turned into a shareable report. See the complete workflow in the sample route survey, or review the hardware package that powers it.

LiDAR route surveys are the foundation for overhead clearance measurement, heavy-haul route planning, and wind energy logistics.
