This book provides an international perspective on improving information to support transportation decision-making. It comprises papers and workshop syntheses from the 9 th International Conference on Transport Survey Methods in Chile in November 2011. The conference was organized into fourteen workshops with both paper presentations and discussions in the workshops forming the majority of the conference activity. The papers reported primarily on research pertaining to continuous improvement in transport survey methodsthe backbone of the transportation data pipeline in most countries. But some papers also addressed the new ways in which innovationnotably technological innovationis being applied to the capture and analysis of data to produce necessary information faster, better, and less expensively. The conference program built on a rich legacy of intellectual pursuits spanning the past two decades, and it is anticipated that the conference will continue into the future. Thus, the contents of this book represent a 5-10 year view through a moving window on the international state of the practice and concerns in transport survey methods.
