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.

Procurement of Private Data
ITS Trends and Perspectives - April 2011 26
$2 million appropriated for data services in up to 25 metro areas
Traffic.com deploys, operates and maintains sensor network
Traffic.com provides data to TV, radio, satellite radio, in-vehicle systems, and maintains public Web site
Agencies get unlimited real-time and archived data for internal use
Federal Intelligent Transportation Infrastructure Program
Procurement
• Data quality audits, QA
• Licensing rights
Systems Integration
• Traffic systems operate with volume/occupancy
• GIS integration with different segment definitions
Data Policies
• What fusion / selection procedures?
• Where are detectors still needed?
Current Challenges
Traffic Information Quality
Traffic information has become abundant but quality remains seldom monitored
• End users are relatively clueless about information quality
• Margins of error are not well understood and used in practice
There are no widespread metrics or evaluation procedures to measure data quality
• Each customer (e.g. car manufacturer, DOT…) conducts its own benchmark
• Evaluation results cannot be readily compared
Postulate:
Harmonized benchmarking methods would benefit both suppliers and customers
• Improve consistency and fairness of evaluations
• Lower overall costs by eliminating duplication of efforts
• Better recognize true value-added and pull quality upward

About NATWG
The North American Traffic Working Group (NATWG) works collaboratively to define, accept and advocate for the unique needs of North America traffic information services. NATWG seeks to develop a coordinated, proactive market driven implementation of traffic and travel information services and products by both influencing international standards efforts and coordinating the development of non-competitive commercial agreements.
