Travel Behavior from Cell Phone Data 9 2.2 Current Practice: Data The current practice of regional model development and implementation has its origins in the early 1960s with major modeling efforts such as those in Chicago, Illinois, and Detroit, Michigan. The overall approach is rooted in the collection of survey data and their analysis with various statistical modeling techniques.

12 Cell Phone Location Data for Travel Behavior Analysis With various degrees of data privacy protection in place, human activities can be observed over longer periods and on a large scale. Recent work has also found that individuals are generally predictable, unique, and slow to explore new places (González et al.

Travel Behavior from Cell Phone Data 13 2.7 Inferring Trip Ends and Activities The traditional approach to travel demand modeling relies on developing analytical procedures and making inferences that allow the use of a small survey sample of daily travel to represent the daily travel in a metropolitan region. Given that cell phone data do not record trips, new analytical procedures are needed to make inferences about activities and travel.
