Complex Network of Urban Trips in Melbourne

We're releasing a new visualization showing a sample of urban trips in Melbourne from a complex network perspective. This is an unofficial release. We'll do the official release when the working paper is published. Click on the picture below to see the interactive visualization.

Link to the interactive visualization (Beta version) here: 

"In 2013, an estimated 14.2 million trips were made on an average weekday in greater Melbourne area. As population increases, the number of daily trips is estimated to increase to 24.9 million in 2051. Such large scale demand for travel between hundreds/thousands of origins and destinations can actually be viewed as a complex network.

In this project, we visualize a sample of daily trips in Melbourne obtained from the Victorian Integrated Survey of Travel and Activity (VISTA) . The visualized complex network includes 46,335 trips (edges) and 183 Statistical Local Areas (nodes).

Each colour represents a cluster of nodes that are strongly connected and form a spatial coherent community. Links are coloured according to their origins' colour. This uncovers the structure of communities in Melbourne inherent to its human mobility patterns."

"Connected Vehicle" Technology: Will Australia Embrace the Change?

A recent video by the USDOT on the benefits of "Connected Vehicle" technology. Perhaps not entirely new for some of you but good for communicating the concept with public and policy makers. The application has already began shaping in the US and a few other countries. Will Australia embrace the change? Are we going to be followers or we may/shall lead the movement?
