Integration and Microservice Development Framework
Traffic control system for State Motorway Management Co. Ltd.
About the Project
Our client operates the traffic and monitoring systems of Hungarian highways which includes the following device types:
- Traffic counter devices
- Variable signs and signals
- SOS phone booths
- Meterological substations
- CCTV subsystems
In the course of time, these devices were continuously acquired and the system was formed from an extremely large variety of devices.
These systems were never integrated into a central application which made it difficult to operate efficiently and precisely.
Our client contacted us to develop a solution for them where devices deployed anywhere in the country can be controlled uniformly from the Budapest headquarters. It was expected that these different types of devices would not exist by subsystem, but that the entire highway network of Hungary should be modeled in the application and that they would be able to perform their work through this interface.
The challenge
Hungarian State Motorway Management Co. Ltd’s highway control and monitoring solution existed in an island-like design – every 70 kilometer section of Hungarian highways with locally installed device control and monitoring center.
If there was an accident at the border of a section, the duty officer of another center was asked by telephone to determine what should be written on the variable signs and signal.
The system could not be controlled and monitored centrally. It was necessary for each section to employ its own on-call staff, although this could have been done with significantly fewer resources if passage between the systems had been ensured.
The protocols of our client’s device systems did not have adequate documentation – sometimes DATEX2 was used – we were only able to properly integrate these devices by reverse engineering the protocols. We had to set up the SOS voice communication directly in the monitoring software.
Another challenge was Integration of inhomogeneous architecture and devices, located at great distances, built up over decades.
Solution
With the help of the solution delivered during the project, only two on-duty experts can perform all the work that was previously done by in 13 monitoring centers.
The central application developed by Molaris can control all devices, handle SOS voice calls, provide overview screens for displaying events and alarms – all this even via a map view. Reports can be generated from the system, and unique interfaces are provided for data publication.
