I am studying the dynamics of the Origin / Destination data. Currently I have access to flight data but need more public data sets ( e.g. mobile phone usage, car traffic, train, bus, etc. ) for further experiments. Any ideas?
Kenth, Thanks for the answer, I already knew about this data and have read some papers about that, however, unfortunately since the challenge is finished , data set is no longer available.
For the US there is some public data on the website of the Bureau of Transportation Statistics (BTS Transtats).

A Triclustering Approach for Time Evolving Graphs
Romain Guigourès, Marc Boullé, Fabrice Rossi
ICDM 2012
Abstract : This paper introduces a novel technique to track structures in time evolving graphs. The method is based on a parameter free approach for three-dimensional co-clustering of the source vertices, the target vertices and the time. All these features are simultaneously segmented in order to build time segments and clusters of vertices whose edge distributions are similar and evolve in the same way over the time segments. The main novelty of this approach lies in that the time segments are directly inferred from the evolution of the edge distribution between the vertices, thus not requiring the user to make an a priori discretization. Experiments conducted on a synthetic dataset illustrate the good behaviour of the technique, and a study of a real-life dataset shows the potential of the proposed approach for exploratory data analysis.

Hi,
Regarding that flight data set,my friend is also doing research based on flight dataset.but she had got that dataset as a word document from that corresponding department .then she modified that document into arff file and uploaded into tool then got result with help of some algorithms.
Quandel.com will help to get timestamp type of data (it is special for sharemarket data)
Suganthi Dinesh , I just saw the http://www.quandel.com but could not find any section for downloading data.
