This brings us again to the purpose of the National Traffic and Road Closure Information System. To achieve the vision of a nationally integrated, interoperable traveler information system capable of sharing data across jurisdictions and modes, critical issues must be addressed — issues such as consistency in the types of data collected, data format, message standards, and data exchange protocols to name a few. Other issues — such as standardized display information, color-coding, and icons — are significant in the effort to provide consistent information in a clearly understood and exchangeable format.
The National Traffic and Road Closure Information System is the mechanism that DOT will use to demonstrate the state of the practice of traveler information data collection and dissemination in the public sector. The ultimate National Traveler Information System of the future will provide standardized data in a consistent format across the country with each locality providing similar data in a consistent format. Many issues remain unresolved, and this is only one of many options to obtain this vision. To date, public and private sectors have been unable to identify clearly what the ultimate National Traveler Information System of the future will look like. It will take all of us working together to make this a reality. DOT’s National Traffic and Road Closure Information System Web site is simply another step DOT has taken to build awareness and commitment to resolve this important issue in the development of an integrated national transportation system.
