Opal Ticketing System: Brief Introduction Opal is an online smart card based public transport ticketing system that runs in New South Wales and

Greater Sydney in Australia. Opal card works there for public transportations including rail, light rail,

government ferry service and bus service. The ferry services between Sydney to Hunter Region, Central

Coast, Southern Highlands, Blue Mountains and Illawara regions.

Passengers and travelers can purchase, keep, reuse and reload Opal cards for travelling within the

aforementioned areas. An Opal card holder needs to keep sufficient balance in the Opal card before

starting their journey by public transports in Sydney and NSW. Before boarding on to the vehicle, a user

needs to tap on the valid Opal card on a specific scanning device connected to the Opal network. After

finishing the journey and before leaving the vehicle, the user will need to tap off the same card on the

similar or the same scanning device. The fare and discounts will be calculated automatically and the Opal

card of the user will be debited with the final fare amount. If a user fails to produce the valid Opal card

during tap off or there is any discrepancy, then the card will be charged with the maximum fare amount

from the user’s Opal card (NSW Opal, 2016).

The Opal card based ticketing system claims to provide the minimum fare for the passengers. To keep the

system coherent with the different ticketing and concession schemes, the project has introduced 4 types of

Opal cards for four different segments of passengers and travelers (NSW Opal, 2016).

The four types of Opal cards are,

• School Opal card for the school students. The school students gets full concession for travelling

by public transport when they travel between the school and the home. This is applicable for the

whole Opal network.

• Gold Senior or Pensioner Opal card is applicable for the NSW pensioners, NSW war widow(ers)

and pensioner concession card holders. They get certain percentage of concession for their fares

while travelling within the Opal network.

• Concession Opal card is applicable for the tertiary students who participates in the tertiary

institutions in NSW from 2015 and onwards. The concession card is also applicable for the job

seekers, trainees and the apprentices.

• Adult Opal cards are applicable for the passengers not belonging to the above categories, and

aged more than 16 years.

• There is additional Opal called Single Trip Opal card for the users who want to use the card for

only once.

Users can top up their cards directly from the credit or debit cards or online banking. Other than that,

there are processes for manual top up from authorized sellers and automatic machines installed at

different locations.

The rollout of the Opal ticketing system was done in multiple phases. It started from December 2012 and

was completed on 1st December 2014.

Opal ticketing is not new for passengers and travelers from NSW and Sydney. Previously, there was

another automated ticketing system in Sydney. That ticketing system used to operate in only the suburb

railways during the 80’s. The updated version of the same automated ticketing system was known as

Sydney AFC or Automated Fare Collection System. The AFC used to run for the ferries and busses.

However, the main problem with the system was lack of integration among different transportation modes

and inability to work on the complex fare calculation process. It also excluded the private bus and ferry

service providers. From April 2010, MyZone was introduced as a solution of the problems of the previous

AFC system. MyZone was a unified solution for major public transports. It was aimed to simplify the fare

system and make it easier for a smart card system to come in action. As a result, the AFC system was not

totally replaced by the MyZone. It was partially implemented. Hence, in reality, the public transport

ticketing system became more complicated and non-user friendly. Then came the TCard system based on

the previous AFC system. After that, Opal was introduced during September 2011. Opal is a short form of

Uniquely Australian and it is named after the national gemstone of Australia, Black Opal (NSW Opal,

2016).

Limitations of the Current Opal Ticketing System In reality, MyZone is still in operation in parallel to Opal. MyZone offers paper based tickets. There are

various limitations of Opal and there are various complaints against the Opal system. The limitations and

complaints are (Saulwick & Grubb, 2014), (The Daily Telegraph, 2015),

• Opal claims to offer the minimum possible fare for a trip when a traveler use a valid Opal card

successfully. In reality, there are instances, when it has been proven wrong. For example, the

single fare for bus and ferry are expensive than usual bus and ferry services without Opal.

• Opal takes penalties very high and for disputes when the users have no faults at all.

• Sometimes the scanning devices fail to communicate with the Opal network and the users pay

fine unreasonably.

• In many cases, users have top up their Opal cards. Their amounts have been debited from their

bank accounts but not confirmed on their Opal account statements.

• If the fare of the public transportation is calculated for the Opal card users and the non-Opal card

users, then it shows that Opal card holders pay more than the other group. Hence, there is a

dissatisfaction among the Opal card holders regarding this fare policy.

• There is a concern related to the privacy issues with Opal cards. The Opal travel information are

by default available to government departments without any warrant. Various authorities and

universities have shown concerns about the matter.

Recommended Strategies Based on the current working process of the Opal cards, the limitations and the concerns regarding the

card, following set of the recommended strategies have been given. The strategies are relate to the design

of the interfaces, performance, working process and improvement for the components of Opal network.

• There is an issue with the top up process of Opal cards. But the issue is technical and stems from

the lack of integration with the banking networks and the system running behind the Opal

network. The system behind the Opal network is not very competent to get updated as and when

people make top up directly from bank or manually from the authorized sellers or automatic

machines. Hence, the integration between the Opal networking system and the payment gateways

and banking networks must be improved and secured.

• The other issue with Opal cards is related to the calculations of the fare. Even though Opal claims

that it offers the minimum possible fare for a trip, customers have raised proved complains that

the paper based ticketing system offers lesser fare when compared with the Opal. It needs either

to implement Opal and a single unified system with lesser fare or the system must show the

details of the fare calculation including base fare and all calculations for extra charges, tax and so

on. Hence, the fare calculation part of the existing Opal system must be improved enough to

make it competent for the complicated Opal fare structure (Saulwick & Grubb, 2014).

• There is a privacy concern related to the Opal cards. Users are concerned that the government

will keep an eye on their privacy related to travelling within the NSW and Sydney area. The issue

is non-technical. It can be resolved by providing an explicit policy to the users about the data

privacy and protection rules and norms followed by Opal. Further, it can state how and why it

collects, process and stores users’ information and travel information for running and

improvement of the Opal system (The Daily Telegraph, 2015).

The Scope of the Proposed System The proposed system is an improved version of the current Opal system that will follow the recommended

improvement strategies for the technical and non-technical limitations related to the system.

The scope of the proposed system is limited to the improvements of the current system only. There will

be no new system or replacement of the existing Opal system. Based on the current feedbacks and

complaints from the users, the recommended strategies have been developed. These recommended

strategies will be deployed in the existing system with the help of suitable technologies and development

strategies. These technologies and strategies will be aligned with the current system in operation and its

development strategy.

If needed, the changes will be deployed in a pilot project with limited capabilities. Later on, the changes

may be modified to accommodate the feedbacks from the users. The final version of the system will be

implemented in multiple phases then.

The scope of the analysis report is limited to the recommendation and identification of the high level

requirements of the proposed system only. Any technical implementation or deployment is out of scope

of the system.

The Proposed System: High Level Requirements The high level requirements of the proposed system are,

• User will need to review and acknowledge the acceptance or decline of the privacy policy.

• Users will need to review and acknowledge the acceptance or decline of the fare policy.

• A user can register for a suitable type of Opal card.

• A user can make top up on the card either from bank account or manually.

• A user can validate the card by tap on service available with the scanning devices.

• A user can tap off the card for getting charged with the minimum fare possible.

• A user can take detailed print out of fare calculation

• A user can check online Opal account for travel information, fare calculation, online top up,

complaints and so on.

Applications of Technologies Particularly, the cloud computing and big data technologies are seemed to be more beneficial for the

implementation of the recommended strategies for the system. The possible applications of both of the

technologies have been given as,

• Cloud computing can be implemented to make the system more robust and to strengthen the

integration with the banking network. Cloud technology will offer highly scalable and updated

services that can be utilized to maximize the performance of the current system (Hugos &

Hulitzky, 2012).

• Before opening any registration form, the users need to check and accept the policies. The

interface designs must incorporate these changes in the designs.

• A huge amount of travel data of the users will be stored and processed by the Opal ticketing

system. Data mining technologies can be applied on these data to find out critical insights from

the data. Those insights can help in improvement of the services, management of the system and

revising the pricing structures (Hugos & Hulitzky, 2012).

• The Opal networking system must be upgraded to suitable database technologies that will help to

implement the data mining applications. For example, it will need suitable ETL process, data

warehousing and so on.
