Real Time Traffic: “The Big Revolution is Two-Way Traffic Data” (2 of 4)

TPEG Traffic Data

Lanctot said he believes that what has happened in Europe is significant for what will happen in the US as bigger pipes to cars continue emerging.

He said the recent Audi announcement was a huge development for the real-time traffic industry globally.

“The concept there was the delivery of TPEG traffic data over the customers’ embedded modem. So you needed a bigger pipe than was available because Europe doesn’t have a digital radio standard,” he said.

“It’s a mess. You don’t have this large landmass where there’s a digital radio solution like HD radio in the US. So Audi made a ground-breaking decision to decide to take that TPEG data and send it over the SIM card. That’s a really big deal.”

However, Lanctot said the strange twist to the story is that in the US they introduced the same platform where the customer plugs in a SIM card – not their own SIM card.

But in spite of having a very big HSPA+ pipe to the car, traffic data is being sent over the Sirius satellite.

Disappointing Experience

“The big problem is, and it’s a controversial issue, is that my own personal experience with Sirius and XM has been extremely disappointing of all the services for real-time traffic data that I have used,” he said.

“Now, it’s hard to get real-time traffic right and I’ve yet to see anybody reproduce real-time traffic reality in complete fidelity on all occasions, in all places and at all times. It’s a very difficult proposition.

“But I can tell you, I’ve had more negative experiences with satellite radio traffic data.” Lanctot said he didn’t know if the data cap on the XM flavor of traffic data had anything to do with this.

“I don’t know if SiriusXM is having to reduce the data set they are getting from Traffic.com to report, but all I can tell you is that whenever I use that service, it’s always a disappointing experience,” he said.

“My experience has been validated by various Tier 1s that have done their own testing and found the Sirius real-time traffic data to be seriously wanting.”

The analyst said he has HD radio in his car but gets the ClearChannel data feed over the FM side-band: “The ClearChannel is using INRIX for the predictive and so on, and I find the INRIX solution with ClearChannel to be more accurate.”
