This document contains a case study on transportation data and visual clustering of journeys using an LRT system. It includes the following key details: 1. Generation and withdrawal rates for 6 stations with total generation of 190,291 and total withdrawal of 186,318. The average is calculated as 188,305. 2. Adjusted generation and withdrawal rates for each station to make total generation equal total withdrawal of 188,305. 3. An origin-destination matrix showing passenger journeys between the 6 stations. 4. Calculations of (a) 45% of journeys between stations and (b) clustering of journeys between stations. 5. A visual representation of the clustered journeys
