Project Description

In this project, we are addressing the challenge of how we might price public transport to balance capacity supply and patronage demand through a tiered approach that considers a base fare and surcharges for distance travelled and time of travel. Our solution requires a unified RTPIS data format that harmonises SIRI data from the buses and GTFS from the light rail.

Data Story

This project will see tiered pricing based on actual public transport utilisation data. In addition, it will involve classic Extract-Transform-Load (ETL) process which can be implemented in any platform. Essentially, it is GTFS + SIRI (where SIRI is converted to GTFS) = unified GTFS feed, or alternatively, it can be SIRI + GTFS (where GTFS is converted to SIRI) = unified SIRI feed via RESTful API. The key is the mapping of data from two disparate sources of different formats to a unified specification.
