TMB-334

The TMB-334 measures the speed, length, direction and position of every vehicle on multi-lane roads. It covers up to four lanes in one or two directions, with two user-defined detection areas, replacing multiple in-road sensors with a single roadside unit. Above-ground installation on existing infrastructure means no road digging, no lane closures and nothing in the pavement to fail.

Data collection / TMB-334

Multi-lane data collection from the roadside.

The TMB-334 is a radar for multi-lane data collection, reporting speed, length, direction and XY position for every vehicle in the detection area.

Quick and easy to install on existing infrastructure, it monitors up to four lanes in one or two directions and replaces multiple in-road sensors. The user can define up to two detection areas, one per direction.

Operation and benefits

Accurate data. Lower budgets.

Reliable and accurate measurement in all weather conditions, day and night. Above-ground installation avoids road digging and reduces spend on security, intervention and maintenance.

Every vehicle, every lane

Speed, length, direction and XY position for each vehicle moving through the detection area, across up to four lanes.

02 / Installation

Above ground, on existing poles

Mounts to infrastructure already in place. No road cutting, no lane closure, no in-road sensors to replace.

03 / Traffic data

Enriched data via RS-485

Per-vehicle speed, length, direction and position delivered through the RS-485 output.
