DESCRIPTION
The term Intelligent Transportation Systems (ITS) was coined over two decades ago to designate applications of information and communication technologies to the operational management of transportation networks. The main promise of ITS has been very consistent over that period: network capacity can be freed up by optimizing traffic controls and empowering users with accurate travel information. It can be debated how much faith practitioners and policy makers have placed in technology by investing their resources, as well as the extent to which Intelligent Transportation Systems have delivered on their promise. However, there is no question that steady and sometimes spectacular advances in computing technologies and usage trickle down to transportation applications in important ways. As a result, new products and services emerge continuously. They include systems that address the direct needs of networks managers, as well as others that are developed in tangential markets (e.g. automotive) or even through non-market mechanisms (e.g. many mobile web applications). This talk presentation reviews major trends in information and communication technologies and demonstrate how each of them is driving innovative transportation services. We attempt to envision how those trends might develop in the future, so that we can finally examine some of their implications for travel demand and network management. There lie both challenges and opportunities for transportation engineers and planners, but either way, profound changes appear inevitable.

ITS Legacy
“I’m setting a national goal: to build an intelligent transportation infrastructure across the United States to save time and lives, and improve the quality of life for Americans. I believe that what we do, we must measure . . . Let us set a very tangible target that will focus our attention . . . I want 75 of our largest metropolitan areas outfitted with a complete intelligent transportation infrastructure in 10 years.”
-- Secretary Peña, 1996

ITS Trends and Perspectives - April 2011 12
The jury is still out on cellular phone geolocation for traffic probes.
The lack of traffic flow sensors continues to inhibit the growth of traveler information and improved transportation management systems.
Emerging technologies include wireless Internet and automated information exchange.
Hope is that with the addition of cellular phones and a national three-digit traveler information number (511), more deployment will occur.
Integrating arterial traffic, emergency vehicle, transit and freeway management would all be important and useful advances.
Electronic Toll Collection is one of the fundamental and earliest deployed ITS technologies.
Optimistically, there will be a steady but slow increase in the use of ITS technologies for transit management.
Only a handful of adaptive control systems are deployed nationally (SCATS, SCOOT, LA’s ATSC).
The number of Americans having access to the Internet is growing rapidly, portending increased use of ITS applications.
