EastLink switches to SICE back office tolling system

EastLink rolls out SICE tolling system.

Development used an agile approach. Requirements specification and system design phases were followed by six sprints of coding and testing. This incremental development saved time and minimised rework.  

Data migration was iterative, with successive data migration tests over more than a year migrating an increasingly large proportion of the data set. Critical data types were prioritised early to reduce risk, such as account balance, tags, vehicles and contact details.  

Four major "day in a life" exercises were aimed at getting as close as possible to running the old and new systems in parallel. The final "day in a life" exercise was a full dress rehearsal of the "go live" transition - from closing the old system, through data migration, starting up business processes and every day operations.

During this exercise, representatives from all business units used the new system as if it was live, and simulation robots mimicked large numbers of website users to test system performance and response times.  

Go live  

The "go live" transition was complex and intricately planned, with most activities occurring over a single weekend.  

All business processes were suspended in the afternoon, Friday 19 May 2017. From that moment toll charges were buffered at each tolling point, ensuring none were lost.  

Data was migrated to the new system. Then the critical data for each customer account in the new system was verified automatically against the old system, including account balance, tags, vehicles, and contact details. Data migration was a remarkable achievement, covering 560,000 customer accounts, 2.8 million casual user accounts, 3.4 million Australian DSRC tags, 18 million Australian vehicles and 32 million trips.  

"The smooth data migration program exceeded expectations, and improved upon previous successes of similar tolling system migrations in Australia," said SICE Australia managing director, Manuel Gonzalez Arrojo.  

Once data migration was validated, the new system was progressively started up on 21 May.  

First, the new system was connected to the toll rating engine and tolling points. Three hours were needed to process the backlog of buffered toll charges. The many external interfaces from the new system were enabled one by one.  

Platform for innovation  

"EastLink has now repositioned onto a state-of-the-art technology platform that will help us innovate and transform the way we do business, to benefit motorists, and take advantage of new trends and technological opportunities," Advic said.
