Activities
included under the Infrastructure Systems Interoperability and Communications
includes the technological issues required to develop and Integrated V2I
Infrastructure System.
|
|
|
|
There
are six projects under this activity:
|
|
|
|
•The Roadway Geometry and Inventory
(RG&I) Trade Study was was undertaken to examine the state of
practice in the mapping industry, from both public and private sectors, and
to determine the current level of detail that is available regarding roadway
features in electronic mapping databases.
|
|
oThe study was initiated in the 3rd
quarter 2009, and will be completed in the 3rd quarter 2010.
|
|
oA Revised Final Report, detailing the findings
of the study, was submitted on June 9, 2010. The report provides
recommendations for moving to an integrated mapping solution that will meet
the requirements for the Geometric Roadway Map Prototype
|
|
|
|
•The Geometric Roadway Map Prototype will use the results of the Roadway
Inventory and Geometry study to direct research solutions for developing,
producing, and maintaining roadway maps of sufficient resolution to meet
IntelliDrive SM application.
|
|
oThe anticipated start date for this project is
4th quarter 2010, with completion in 2012.
|
|
oThe outcome of this project will be mapping
solutions that meet the needs of the IntelliDrive program, including
accuracy, resolution and deployability.
|
|
|
|
•The Positioning Prototype will
incorporate a trade study to quantify the resolution and capabilities of
current positioning technologies, including differentially corrected
GPS. The project will assess the positioning needs for intersection
safety applications and will result in a selection of the positioning
technology that can fill those requirements.
Unit testing will be conducted at TFHRC.
|
|
oThe project is anticipated to start in 3rd
quarter 2010 with completion in 1st / 2nd quarter 2012.
|
|
oThe outcome of this project will include a
trade study on the capabilities of existing positioning technologies, and
potential solutions to provide the positioning requirements of V2I
intersections safety applications.
|
|
|
|
•The Communications Trade Study will
evaluate and document the capabilities of existing communications
technologies that could be used in the IntelliDrive program. A matrix will be
developed that will allow users to select an appropriate communications
technology for an application based on the requirements of the application
including latency, message size, transmission frequency, etc.
|
|
oThe trade study is anticipated to begin in the
3rd quarter 2010, with completion in the 1st quarter
2011.
|
|
oThe outcome of the trade study will identify
the capabilities of available communications technologies in a format that
can be used for selection of an appropriate technology for a given
application.
|
|
|
|
• The
Communications Requirements project will assess the telecommunications
requirements for each IntelliDrive application and, based on the
Communications Trade Study, select an appropriate communications technology
for each application. Even though it
has been decided that DSRC will be used for Safety applications, an
assessment needs to be done for mobility and environmental applications.
|
|
oThis project is anticipated to start in 1st
quarter 2011, with completion in 1st quarter 2012.
|
|
oThe project will result document
recommendations on technologies to meet the communications requirements of
V2I applications.
|
|
|
|
•The V2I Security Requirements project will be coordinated with the V2V Security . This will address the Certificate Authority
for messages, validation of messages, verifying sources of messages and other
data transfer security issues as they relate to infrastructure components and
to backhaul networks.
|
|
oThis project is anticipated to start in 1st
quarter 2011 and will be completed in 1st quarter 2012.
|
|
oThis project will be identify and document information
required for security activities within the IntelliDriveSM program
as well as the Infrastructure Study / Footprint Analysis in Track 5.
