These costs were incurred by three transit agencies that deployed a Side Object Detection System (SODS) in 2004 (which was the first commercial deployment of a SODS). The acquisition costs on a per unit basis were $2,000, however, because the acquisition was part of a new bus procurement which included installation, the costs of retrofits may be higher.
