Iowa DOT consumes data from multiple streams, including probe data from INRIX and weather data from Mesonet, which is stored to assist in smart decision making. The cumulative data size for the past 5 years of data can easily be in the range of 15–20 terabytes.
Despite access to unprecedented amount of data, decision makers are often restricted in their ability to explore these data sets. Under the present set up, a simple query, such as how many crashes happen during congested conditions, can’t be answered easily and requires a dedicated research project.
This research proposes to demonstrate a simple proof of concept of cyberinfrastructure that addresses constraints on decision makers. The three data sets that will be used for this demonstration will be crash, INRIX mobility, and weather for the past three years.
