Research for the AASHTO Standing Committee on Planning. Task 131. Transportation Data Integration to Develop Planning Performance Measures

Every year, state, regional, and local agencies across the nation measure transportation systems performance and make numerous planning and operations decisions. These   complex decision-making processes need large amounts of data. To be useful, data from a variety of sources—that may have been collected for different purposes—has to be transformed into information.  Data integration offers a significant opportunity to make improve decision-making through the use of a data management process that efficiently and effectively produces new information derived from isolated heterogeneous data sets.   The lack of proper data integration tools can result in widely different analytical outcomes and negatively affect the quality of decision-making. For example, traffic flow speed is often analyzed to identify bottlenecks and problematic areas with low levels of service. However, if actual speeds are looked at without considering posted speeds, queue lengths, and volumes, actual speed data  can potentially lead to inappropriate  conclusions about the  need for improvements. The fields of transportation forecasting, planning and operations have been slow to adopt and benefit from the advantages of data integration solutions in the face of a rapidly changing urban data environment, an enormous increase in new transportation data sources and data collection technologies, and the establishment of new commercial data sources.  Data integration issues have therefore become more important in order to ensure that a complete and coherent picture of past and emerging performance.  Data integration solutions should facilitate easy access to disparate transportation data sets for data mining, comparisons, visualization and other functions that rely on data.   The objectives of this research are to (1) examine the current state of transportation data integration, with an emphasis on performance measurement data and data that are relevant for planning and maintenance decisions; and (2) provide guidance for data management program development at state, regional and local levels. The research results should summarize current practices in the transportation data integration, including at a minimum forecasting, planning, operations, asset management, transportation economics, transportation modeling and other related fields.
