Two students, Tabitha Abeka and Christabel Acquaye, from the Department of Computer Engineering of Kwame Nkrumah Uni. of Science & Tech. have developed a better electronic toll collection system. This is an effort to reduce the delays at toll stations on the road.
As the Ghanaian government readies to give out some of the toll booths to be managed by private companies, this move by the students seems apt.
Electronic toll booths sited at Tema Plaza and in other places seem to record more revenue as compared to the ones with the complete human interface. The catch with the current electronic toll systems is traffic delays.
Since the system is electronic, sometimes the barrier itself refuses to lift and let vehicles pass. These are some of the problems factored in by the KNUST students Abeka and Acquaye to develop a whole new and upgraded electronic toll collection system.
Their toll collection system is also equipped with a mobile app to help solve this problem.

Ms Acqauye and her colleague, Abeka, also factored in making more revenue than the current toll collection systems. Tabitha Abeka pinpointed that, “A 2017 NHIA report shows the government has received 1.2 billion cedis as revenue but had a debt of 7 billion.”
Thus, they developed a new system with better efficiency to make help more revenue and reduce debt.

How the new electronic toll collection system works

The new toll system comes with a central database and web server. Then there is the prepaid account system for drivers. Tags are then placed somewhere on the windscreen together with the DVLA roadworthy and vehicle registration stickers.
On reaching the toll station, the reader scans the stickers and the toll fee is deducted from the driver’s prepaid account.
Acquaye noted, “The account works like the prepaid system we have except in this case we have a tag having information on a vehicle. Anytime you reach the toll gate you wouldn’t have to stop.”
With the mobile app, vehicle owners can see and manage transactions and their account info, respectively. For defaulters, the system records negatives. Such persons will be required to pay all debts before they can renew their roadworthy certificates.
Since the system stores where and when a toll was deducted, vehicles are somehow tracked. This inevitable as the info is needed to discern that the driver owes toll fees or not.
On the other hand, it is a good feature as it gives the police the opportunity to quickly locate or determine where a certain stolen vehicle is.
Also, the KNUST electronic toll collection system reduces debt and revenues leakages as it removes the human interface. Above all, the system would be efficient enough to drastically reduce congestion around toll stations.
