Intelligent Transportation Expert on What Leaders Think About V2X

V2V and V2X

by Jon LeSage, Deal­er Digest Dai­ly

An expert on intel­li­gent trans­porta­tion gave his per­spec­tives on what’s hap­pen­ing with V2X – which is the cross­road where Vehi­cle to Vehi­cle (V2V) and Vehi­cle to Infra­struc­ture (V2I) ser­vices come togeth­er. It’s com­mu­ni­ca­tion between dri­vers, vehi­cles, road sen­sors, sig­nage, telem­at­ics, and even pedes­tri­ans, into one inter­ac­tive com­mu­ni­ca­tions net­work. It deals with core issues – safe­ty, traf­fic con­ges­tion, fuel con­sump­tion, and emis­sions.

Intel­li­gent Trans­porta­tion Soci­ety (ITS) of Amer­i­ca is an NGO that ini­tial­ly start­ed out in 1991 as a fed­er­al advi­so­ry com­mit­tee to the US Dept. of Trans­porta­tion. All of the major automak­ers belong to it, along with major fed­er­al, state, region­al, and munic­i­pal gov­ern­ment trans­porta­tion agen­cies, AAA chap­ters, tech­nol­o­gy sup­pli­ers, uni­ver­si­ties and research cen­ters, and con­sul­tants.

Steven Bay­less, Senior Direc­tor, Telecom­mu­ni­ca­tions and Telem­at­ics at ITS Amer­i­ca, talked about why a com­mon plat­form for vehi­cle com­mu­ni­ca­tions will pro­vide more oppor­tu­ni­ty for the indus­try than indi­vid­ual OEM solu­tions. All of the pas­sen­ger and com­mer­cial vehi­cles on the road need to be inte­grat­ed into the right web of com­mu­ni­ca­tions.

Here’s a few of the issues he talked about…

  1. The US DOT would like to see after­mar­ket devices that pro­vide some safe­ty appli­ca­tion capa­bil­i­ty – V2V com­mu­ni­ca­tions using a brought-in device that would allow cur­rent pas­sen­ger cars to pro­vide some func­tion­al­i­ty to those vehi­cles right away, rather than to wait for automak­ers to install capa­bil­i­ty in new vehi­cles.
  2. Anoth­er path is infra­struc­ture, intro­duc­ing road­side units at inter­sec­tions run­ning inter­sec­tion appli­ca­tions to encour­age uptake of the tech­nol­o­gy in vehi­cles and even per­haps after­mar­ket devices.
  3. Anoth­er pos­si­ble strat­e­gy is the inclu­sion of oth­er types of road users, for exam­ple, motor­cy­cles and per­haps pedes­tri­ans that might car­ry ded­i­cat­ed short-range com­mu­ni­ca­tions capa­bil­i­ty in their mobile phones.
  4. Most folks involved in the pro­gram don’t think mobile phones would be per­fect sub­sti­tutes for a fac­to­ry-installed sys­tem. He thinks there are a lot more appli­ca­tions that can be sup­port­ed from an OEM-installed sys­tem than could be sup­port­ed from a mobile device sys­tem. Mobile devices are more con­strained in terms of capa­bil­i­ty, the accu­ra­cy of GPS, and they are bat­tery-con­strained and don’t have as much pow­er.
  5. The poten­tial for V2X is much greater than the poten­tial for some of these oth­er tech­nolo­gies, which are more sin­gle-pur­pose and more expen­sive. They think that V2X will be able to cre­ate a plat­form that will allow many more crash-avoid­ance and mobil­i­ty appli­ca­tions to be sup­port­ed simul­ta­ne­ous­ly.
