The statement of the problem
In 2019, the “Latvian Road Maintenance” operator became a partner of “Waze” within the “Connected Citizens “program and gained access to the flow of waze alert events. Events are available in XML and JSON formats, and each event is characterized by coordinates, insertion date, type, subtype, city and street affiliation, and “Waze” calculated quality scores.
As it is difficult to process the specific XML data files directly, there was a need for a specialized system for filtering event information, achiving, visualizing and analyzing processed events. According to the “Latvian Road Maintenance” order, the specialists of the RTU Department of Management Information Technology specialists : under the leadership of the Associate professor Jānis Kampars, it was developed and handed over to use in the autumn of 2019. The system is used on a daily basis by the “Latvian Road Maintenance” company and Latvian State Road employees.
