Unique Application of the TPEG Standard over IP is Production Ready

KIRKLAND, Washington, July 28, 2010 - INRIX(R), the leading provider of traffic and driver services, introduced
TPEG Connect, a unique application of the Transport Protocol Experts Group
(TPEG) standard that significantly reduces costs to drivers and vehicle OEMs
for delivering traffic and travel information to connected vehicles and
mobile devices.


INRIX TPEG Connect provides automakers and navigation application
providers with the ability to optimize data payloads and connectivity for
delivering richer real-time and predictive traffic flow, traffic incident
information and other connected driver services like weather, electric
vehicle services and fuel prices. Based upon the TPEG format, TPEG Connect
delivers this dynamic information using TPEG over IP (over the Internet),
removing the significant constraints of traditional traffic broadcast
delivery formats such as RDS-TMC.

"With TPEG Connect, INRIX is once again delivering a first to market
technology innovation ready for customers to take into production today,"
said INRIX Chief Technology Officer Craig Chapman. "By readying the standard
for use over IP, INRIX TPEG Connect removes key technical and commercial
hurdles for our customers accelerating the delivery of next generation
traffic applications and driver services."

In testing since last year, INRIX TPEG Connect provides delta support
that can reduce data payloads by up to 50 percent on each message request. In
turn, this unique delivery method can help OEMs and consumers save on
connectivity costs by ensuring only the most location-relevant real-time
information is delivered to the vehicle or the consumer's mobile device –
particularly across Europe where pre-paid data plans are the norm and data
roaming fees can be exorbitant. As more data-intensive applications become
ubiquitous in the car and across a wide array of smartphones, portable
navigation devices (PNDs) and tablet computers, optimizing for the delivery
of only the most location-relevant information becomes critical.

Originally designed for digital broadcast networks, INRIX has adapted
TPEG for use in connected vehicles and mobile devices using cellular data
networks. As a central enabling technology for next generation traffic
services, TPEG was developed over the last decade within the TPEG Forum (a
standardization body supported by the European Broadcasting Union) and is
ISO/CEN certified. INRIX's TPEG Connect covers all key aspects of processing
traffic and travel data including:

    - Authentication: Determines the device over TCP/IP and ensures that the
      device is authorized to receive the data requested.
    - Encoding/decoding: Codes the TPEG binary protocol or TPEGml into a set
      of high-level objects representing the message's semantics. Efficient
      filtering reduces system resource requirements.
    - Data Management: Controls the creation, updating and deletion of TPEG
      messages; Manages an efficient in-memory message database that always
      accurately mirrors the latest traffic information.
    - Smart Traffic Information Retrieval: Higher level application
      components can easily query the message database for selecting traffic
      information that is actually relevant in the application context using
      spatial, temporal or semantic criteria to support location-based and
      personalized driver services.
    - Data Presentation & Downstream Notification: Features API provisions
      for integrating with other client-side components requiring notification
      about new, updated, or deleted traffic and driver services information.
    - Monitoring: Continuously monitors and analyzes the status of the
      message database in real-time.
