We should try to solve for the key core indicators first and go from there. Procedures must be in place to maintain commonality and comparability. A common analysis tool for all can help to create an awareness of cross-sectoral issues. The ultimate benefit is to make the best use of limited resources. We want to use data to improve our knowledge and understanding of transportation issues.
Harmonization can make the best use of limited data, such as in conducting cross-country studies.
Harmonization will make it easier to learn from other countries and to build on the strengths of other models. Reducing the cost of collecting data would be another likely benefit. Using other countries' already collected data will also improve quality and coverage in terms of reconciliation. The new data we collect will go toward improving transportation statistics to that end. In the United States, we are changing our economic institutions so that investment priorities are clearer.
