recent years, there has been more focus from the automotive industry
to develop technology that optimizes drivers’ access to
information, while at the same time staying safe and focused on the
road. Large, colorful displays and touch screens are increasingly
common in the “center stack” of new vehicles.
these displays were only found in high-end vehicles or embedded
navigation systems. Today we see these displays integrated into cars
across all price points, sometimes as standard equipment, and
including more features such as a display of vehicle diagnostic
information; heightened navigation; and basic infotainment systems
like radio, CD players and portable audio players.
addition, automotive companies are now using these displays to
present content found on the driver’s smartphone.
challenge becomes how to deliver relevant information to the driver
in a manner that is cost-effective, ubiquitous and safe.
the casual observer, the Internet is a good conduit through which to
deliver such information. However, Internet-only content delivery to
vehicles has several disadvantages: Availability, bandwidth, latency,
reliability, cost of integrated devices and the cost of delivering
services make this model less than optimal.
pairing with the vehicles can be challenging for some customers, and
yet others may decide not to pair the phone with their vehicle. So
how can an automotive company deliver relevant information to the
dashboard in an efficient, cost-effective manner?
Traffic Network leads the navigation solution industry by providing
real-time local traffic flow and incident information with graphics
to vehicle dashboards via an HD Radio signal or IP connectivity.
latest HD Hybrid technology, branded “TTN HD+,” delivers
easy-to-access features that include Doppler RADAR; real-time local
and national weather forecasts from The Weather Channel; traffic
updates; and the ability to receive news, stocks, sport scores and
TTN HD+ solution provides real-time, cost-efficient information that
is constantly available nationwide, even as the car moves through
varying signal conditions.
uses HD Radio’s Advanced Application Services framework to dedicate
a portion of a transmitting station’s digital bandwidth to this
data content. This content is broadcast and repeated continually for
receivers in the coverage area to download the data and provide
up-to-date and relevant information to the dashboard. Typically,
these systems will have a dedicated sub-tuner looking for a radio
station that carries the TTN data package.
offers best-in-class HD digital coverage in the U.S. TTN is a
subsidiary of Clear Channel and therefore the data is available on
all Clear Channel FM HD radio stations. TTN offers more stations and
local HD markets than any other provider.
HD+ is available in large and small markets nationwide. The TTN
network resides on all of the Clear Channel stations in any given
market, which typically offers three to five stations. This provides
additional redundancy to unforeseen transmission failures (antenna,
transmitter, generator, data circuits) and also in many markets
allows for multiple “angles of attack.” Where one transmitter
site might be shielded at a receiver location, TTN often offers other
signals providing service to same area.
to other delivery technologies such as satellite, TTN provides
extensive premium traffic services, and offers bandwidth in each
market dedicated to hyper-local content.
FM HD reception is not available, capable receivers can switch to
hybrid IP technology and obtain the same quality content via the
Internet through a connected solution. Receiver connectivity can be
direct via an embedded cellular device or, more common these days,
paired with a smartphone that acts as a proxy.
addition to its best-in-class technical performance, TTN provides
best-in-class content. TTN’s traffic information is gathered
through its network of operations centers around the country. As the
largest and most experienced provider of traffic flow and incident
information, TTN has a wider local footprint than any other provider.
16 around-the-clock operations centers in the U.S. and unparalleled
data-gathering resources, TTN provides relevant and accurate traffic
data to in-vehicle systems, handheld devices and the largest network
of television and radio affiliates. In 2012, TTN partnered with The
Weather Channel to enhance its in-vehicle offering by including
Doppler RADAR imagery and hyper-local forecasts to be included in the
TTN HD+ solution.
of the Telematics Update 2012/2013 Best Navigation Solution award,
TTN HD+ launched the first use of TPEG protocol for digital traffic
information in the U.S. In addition to data for embedded navigation
systems, TTN has also released the Simple Traffic Map, a tile-based,
color-coded traffic map that displays congestion levels, which is
available in lower-cost vehicles without a navigation system.
HD+ content and delivery is available factory-installed in select
Toyota and Lexus vehicles, and is available to all vehicles through
aftermarket JVC navigation systems.
