Researchers of the UWICORE laboratory, of the Department of Communications Engineering and the I3E Engineering Research Centre of the Miguel Hernández University (UMH) of Elche, have proven that the coexistence between autonomous and conventional vehicles will noticeably influence the estimated effects of autonomous driving. According to this study, until at least 15 percent of vehicles are autonomous, no benefit will be seen regarding the fluidity of traffic and the capabilities of motorways unless solutions are developed to guarantee the efficient coexistence of autonomous and conventional vehicles.
