Application of SCADA Technology for the Automatic Monitoring & Control of Road Traffic

This research proposes to adopt Supervisory Control and Data Acquisition Technology in the improvement of the performance of an already-existing intelligent traffic control system which was based on the application of fuzzy logic and ANN with the use of inexpensive and opensource materials such as the CDS photoresistors. Object-oriented system analysis was adopted in the modelling of the relational database system used in securely storing data related to road traffic. This database system also provides real time access to data for the end-users such as vehicle drivers and road traffic officials. Results obtained indicate that the SCADA-improved system outperforms the former system by not only providing intuitive GUI interface to the end-users which enables them to make informed decisions concerning appropriate route to follow, the SCADA-improved system also further reduced the average waiting time of vehicles on traffic queues in that the flow rate of vehicles on queue were increased.
