To accomplish this, the interior of the tunnel was designed with the help of, among others, traffic psychologists at a research institute and professional light designers, as well as a driving simulator.
Tuneļa izveidē tika ņemti vērā satiksmes psihologu un profesionālu gaismas dizaineru ieteikumi, kā arī braukšanas trenažierī gūtie dati.
