Mapping the lateness of Dublin buses

Dublin Bus does not release location information of its buses while in motion. However, they do periodically release information gathered from each stop a bus makes. Sometimes it can be found on Smart Dublin. The BCD team looked at one of the days in a sample of this data added to Smart Dublin to track where, how late, and at what time of day buses were late in Dublin. Using R mapping and data table

Clustering Dublin traffic time series

Unsupervised clustering processes bring order to unexplored data by creating groups, or clusters, of input data objects based on properties which are otherwise difficult to see with the naked eye. The similarities and differences between clusters and their object members reveal a structure that can be further investigated. Clustering may be the first step in an analytical process to understand a large collection of data with multiple dimensions which are difficult to view at once.
