Vehicle Road Data Collection and Vehicle Testing

OTAM performs road data acquisition (RLD) studies required by vehicle engineering and carries out the necessary pre-preparation, testing, post-test analysis and evaluation, and transfer of data to the test environment.

• Test route determination study.

• Simulation study to determine the data collection areas in the vehicle or system.

• Vehicle instrumentation. (Sensor and analyzer placements, strain gauge, accelerometer, microphone, load cell, tachometer applications)

• Post-processing of collected data.

• Cleaning and speeding up the collected route data.

• Organizing the route data so that it can be played back in the test system.

• Performing accelerated tests in a laboratory environment.
