Au­to­ma­tion is not just about the ve­hi­cles, says new re­port

Business Day - Motor News - - MOTOR NEWS -

Au­to­mated ve­hi­cles prom­ise more safety by elim­i­nat­ing crashes linked to hu­man er­ror.

But claims that self-driv­ing cars could avoid 90% of road deaths by elim­i­nat­ing th­ese er­rors are untested, says a new re­port by the In­ter­na­tional Trans­port Fo­rum.

Shared re­spon­si­bil­ity be­tween ro­bot and hu­man driv­ers can, in fact, lead to more com­plex driv­ing de­ci­sions.

The un­in­tended con­se­quences might make driv­ing less safe, not more.

In sit­u­a­tions where hu­mans take over con­trol from ro­bots, more crashes might oc­cur among “av­er­age” driv­ers who nor­mally do not take risks.

Full au­to­ma­tion may re­duce the num­ber of se­vere crashes sig­nif­i­cantly. Yet with par­tially au­to­mated sys­tems, hu­mans re­tain an ad­van­tage in many con­texts. Over­com­ing this gap re­quires mul­ti­ple sen­sors and con­nec­tiv­ity with in­fras­truc­ture.

Such fully au­to­mated and con­nected cars are vul­ner­a­ble to cy­ber­se­cu­rity risks, how­ever.

“The avoid­ance of crashes should never de­pend on ac­cess to shared ex­ter­nal communication chan­nels alone”, the re­port warns.

It rec­om­mends de­sign­ing au­to­mated ve­hi­cles so that safety-crit­i­cal sys­tems are func­tion­ally in­de­pen­dent and can­not fail in case of con­nec­tiv­ity is­sues.

Au­to­ma­tion makes it more ur­gent to adopt a Safe Sys­tem ap­proach to road trans­port. A Safe Sys­tem or­gan­ises all el­e­ments of road traf­fic in a way that when one safety mech­a­nism fails, another steps in to pre­vent a crash, or at least se­ri­ous in­jury.

Ap­ply­ing this ap­proach to au­to­mated driv­ing means the traf­fic sys­tem will ac­count for ma­chine er­rors.

The re­port cau­tions against us­ing safety per­for­mance to mar­ket com­pet­ing au­to­mated ve­hi­cles. “The rel­a­tive safety level of ve­hi­cles … should not be a com­pe­ti­tion is­sue. The reg­u­la­tory frame­work should en­sure max­i­mum achiev­able road safety, guar­an­teed by in­dus­try, as a pre­con­di­tion of al­low­ing th­ese ve­hi­cles … to op­er­ate,” the re­port says.

Other rec­om­men­da­tions in the re­port in­clude a re­quire­ment for au­to­mated ve­hi­cles to re­port safety-rel­e­vant data, es­tab­lish com­pre­hen­sive cy­ber­se­cu­rity prin­ci­ples for au­to­mated driv­ing and pro­vide clear, tar­geted mes­sag­ing of ve­hi­cle ca­pa­bil­i­ties.

A SAFE SYS­TEM OR­GAN­ISES ALL EL­E­MENTS OF ROAD TRAF­FIC IN A WAY THAT WHEN ONE SAFETY MECH­A­NISM FAILS, ANOTHER STEPS IN

It is es­sen­tial that ve­hi­cles and in­fras­truc­ture work to­gether for au­ton­o­mous ve­hi­cles.
