A study by the UK's University of Southampton’s Transportation Research Group (TRG) assessed whether connected and automated vehicles (CAVs) could be accommodated by building narrower freeway lanes. Earlier studies in the field of CAV highway provisions have been based on existing design standards, or on roads built without taking into account vehicles’ close route- tracking capabilities. To fill this gap, the research team applied data from wheel odometry-based 3D Lidar, inertial measurements and a GPS-based locating unit to a truck with onerous vehicle space demands to identify the additional space allowance that would be needed to cope with the minor tracking deviations that such a vehicle would inevitably make.
