Transport regulatory authority in Singapore commissioned a system to:
- Automatically discover wrong fare incidents and flag commuter’s cards affected by wrong fare charging; and
- Detect emerging fault trends in fare collection equipment so that corrective action could be taken in a timely manner
The challenge was to handle very large volume of ticketing, bus operations, transit and hardware events data. Smart deployed a Hadoop & Hive based warehouse and Spark based distributed computing solution to detect Wrong Fares.
