Assessment of Data Quality Needs for Use in Transportation Applications

The objective of this project is to investigate the data quality measures and how they are applied in existing systems. The project explores the relevance of the data quality measures that were defined in a report entitled "Traffic Data Quality Measures" and presents an overview of the requirements for the implementation of a real-time information program in addition to the use of these data for non real-time transportation applications. Specifically, the project focuses on real-time travel information applications within six primary interfaces (traffic management information, maintenance and construction management, transit management and information, information service provider information, parking information, and emergency management information) and their associated applications as identified in the publication of "Interim Guidance on the Information Sharing Specifications and Data Exchange Formats for the Real-Time System Management Information Program". In addition, the project also focuses on the use of historical real-time data for non real-time applications including transportation planning, use of historical data for traffic management and control, and environmental impact analysis. The project will assess the existing data sources available at the Virginia Department of Transportation (VDOT) and other private data collection agencies, identify the data needs and data quality needs for different real-time and non real-time applications, and identify any gaps in existing data sources, and make any recommendations to fill in these gaps. The project will also identify any synergies in various application data needs. Additionally, this project showcases a short-term travel time prediction method that takes into account the data needs of the real-time applications. The objective of this research is to prepare and disseminate accurate short-term (up to 15 minutes ahead) travel time predictions on major highway corridors in the state of Maryland using real-time and archived Bluetooth travel time samples, probe-based INRIX data, and stationary sensor data pooled together in Regional Integrated Transportation Information System (RITIS).
