In the past, transportation data was collected through the limited deployment of infrastructure-based sensors and manual spot counts and surveys. Massive on-line data being collected on a nearly 24/7 basis enable researchers and transportation managers alike to quantify a number of realistic “performance measures” that allow transportation agencies to make timely and proactive decisions. However, there are great needs to integrate and mine the massive on-line operational data with performance measurements not only to make long-term strategic planning decisions but also for the execution of relatively short-term tactical decisions.
