Investigating UK Traffic With Principal Component Analysis

Michael Grogan shows us how to use Principal Component Analysis (PCA) to classify route segments in UK transportation data:

Specifically, let us assume that we wish to analyze traffic density for buses and coaches. The main thing we are interested in is the frequency of traffic across a particular route.

Let’s take an example. If buses cover 100 miles on a route that is 5 miles long within a certain timeframe, then the frequency will be greater than 100 miles covered on a route that is 10 miles long over the same time period.

Read on for an interesting example.
