Abstract
Intelligent Transportation Systems make it possible to imagine a near future
in which cars will be able to foresee and avoid collisions, navigate the
quickest route to their destination, making use of up-to-the minute traffic
reports, identify the nearest available parking slot and minimize their carbon
emissions. The main motivation for ITS is the improvement of road safety. It
is a startling fact that some 1.35 million people are estimated to die on the
world' s roads each year, and over 35 million are injured.
Standards work in ITS have been ongoing for more than 30 years, including such organizations as ITU, ETSI, IEEE, and ISO.
ITS development, at the present time, mostly concentrated on a car itself; an
exception is "intelligent" tolling. Symbiosis of car operation functions with
enhancement supported by radar and telecommunications technologies seems to be
a very effective way to construct a car as a part of ITS. The goal is to
reduce probability of driver' s mistakes, which are the main cause of
accidents. This goal can be achieved by putting a burden to analyze the road
situation and to make decisions based on such an analysis on a computer. Such
a computer is supported by radars for sensing the road situation and by
telecommunications devices to communicate with other vehicles, intelligent
road and law enforcement/emergency personnel.
This report addresses ITS telecommunications and radar technologies and related markets.
- A. The report analyzes technologies and markets for CDPS - Collision
Detection and Prevention Systems. They include RCDPS - Radar CDPS and CCDPS
- Communications CDPS. Devices, which belong to different classes, can work
either independently, or together, supporting each other.
- This report shows that both classes of the devices were adopted from other
industries, namely radar and telecommunications. This adoption requires a lot
of adjustment and design of the systems specific for the car collision
prevention application. The report analyzes the CDPS market and provides a
market forecast for 2009-2013. The analysis is based on the author' s model of
the market and the use of publicly available information as well as on the
results of interviews with vendors.
- B. This report also addresses marketing and technological issues of
specific wireless technologies for ITS. Particular, the following evolving
technologies and specific projects were considered:
- 1. 5.9 GHz DSRC- This technology, as it seen today, may eventually
replace the 915 MHz DSRC in the U.S. and the 5.8 GHz DSRC in Europe. 5.9 GHz
DSRC is the emerging communication technology that offers standardized ITS
products and benefits in national large-scale deployments. U.S. DOT and the
automotive OEMs will be the strategic players making deployment decisions in
the 2009-2010 timeframe; though large-scale projects are expected only in
the 2014-2015 time frame. 5.9 GHz DSRC systems provide a significant
enhancement in communication capabilities over all previous ITS systems.
DSRC will support multiple uses in vehicle / public safety and commercial
applications that cannot be achieved today. DSRC is a cost-effective
communication service, especially when compared with current cellular and
satellite systems.
- 2. CALM (Continuous Air-interface, Long and Medium Range) represents an
ambitious attempt to provide a platform for a wide range of future
communications requirements for ITS. As such, it cuts across several ongoing
standards-making efforts, including those of the ITU (like NGN). The aim of
CALM is to provide wide area communications to support ITS applications that
work equally well on a variety of different network platforms, including 2G
(GSM/GPRS), 3G (IMT-2000), 4G (IMT Advanced); as well as satellite,
microwave, mm-wave, infrared, WiMax and short - range technologies like WiFi.
- 3. The report also concentrates on the analysis of multiple ITS
networking projects that are conducting in various parts of the world. These
projects, which are organized by the industry and governmental agencies with
participation of standard organizations (such as ETSI, CEN, IEEE and other)
are testing various technologies to find and define optimal ways to enhance
ITS with reliable means of communications. It seems that 5.9 GHz DSRC is in
the wining position to be used for many ITS applications-it was recently
approved for use in Europe (though Japan and some other countries utilize
different technologies). CALM is coming into the play as an "universal
platform" allowing utilization of a set of wireless protocols.
The report also provides marketing statistics for some of the discussed
technologies.
