Urban trips in Chicago as a complex network


This is an illustration of urban trips in Chicago as a complex network, regardless of the road network. Each link represents a trip from an origin to destination. The plotted network includes more than 78,000 trips (or links).

The data is from the 2007 Chicago Household Travel Survey which includes daily travel diaries of more than 14,000 households in Chicago. It includes unique IDs for each household and person, travel modes, departure times, etc. So we can track each person and connect his/her trips to build tours. More interesting analysis results will be posted soon.

It covers the need to develop new freight transport models and scientific tools to counter internal and external economic impacts, and delivers theoretical and empirical input on three levels: global, regional and local (urban). Full information and online purchasing are available through the book’s web page.

Analytics, Big Data, and Lego
