Intelligent transportation systems (ITS) are poised for strong growth and widespread deployment in a variety of applications as the governments of various countries realize the importance of efficient traffic and travel management using existing resources and infrastructure. With slow driver reaction time having been identified as a major cause of accidents the world over, governments are looking at novel ways of averting mishaps and ensuring safer roads through the use of ITS.
New research from Frost & Sullivan (www.ti.frost.com), Intelligent Transportation Systems - Enabling Technologies and Innovations, finds that there are numerous applications such as collision avoidance, incident management, and weather alerts, among others, that benefit from the use of ITS. Large-scale deployment of these systems is expected to improve traffic and related problems in the years to come.
"ITS relies on various technologies for their optimal functioning, of which wireless communication technologies are perhaps the most important," observes Frost & Sullivan research analyst Arvind Arun. "In particular, wireless technologies such as dedicated short range communication (DSRC) and wireless access for vehicular environments (WAVE) have had a profound impact on ITS applications due to their ubiquity and ability to facilitate rapid and simultaneous intimation to all drivers involved in an emergency as opposed to an information relay from one driver to the next."
Almost all ITS applications from collision avoidance to traveler information systems make use of wireless technologies, with safety undeniably being the most important application. Technologies such as DSRC and WAVE are unique in that they have been specifically designed to meet the needs of the ITS sector and have desirable features such as low latency and high data rate.
DSRC, which operates in the 5.9 GHz licensed band is almost exclusively used for vehicle-to-vehicle and vehicle-to-infrastructure communication, while WAVE is used in collision avoidance and vehicle safety services. GPS is another valuable technology as it eliminates the need for cell phone towers and is used for applications such as automatic vehicle location and intimation of drivers and pedestrians that are unwittingly moving along collision paths.
