This paper describes the development and use of an open source, geospatially enabled framework and applies that platform to the analysis of freight truck travel time data that were extracted from the National Performance Management Research Dataset (NPMRDS). The NPMRDS is provided by HERE-Navteq and the American Transportation Research Institute under a contract with the U.S. Department of Transportation. The analysis platform is based on the PostgreSQL database and uses the PostGIS extension to enable spatial analysis inside the database. The study team developed a methodology to combine information from the NPMRDS, the National Highway Planning Network, and the Illinois Department of Transportation’s Illinois Roadway Information System statewide roadway inventory. Geographic information system tools and the capabilities of the PostgreSQL database addressed incompatibilities and inconsistencies between supporting data sets and allowed the study team to find, access, use, and combine data from different sources. The study used these data sources to develop roadway performance measures for truck–rail intermodal connectors (IMCs) and compare these connectors with roads that had similar attributes. When compared with roadway segments with similar characteristics, speeds on IMCs often demonstrated greater uniformity and consistency.
