Sustainable decision support based on relevant data
Maintenance of roads and streets based on objective data
About state roads there are many methods to prioritise when, where and how a road should be maintained but not for city streets. City streets’ states can not be described as similar to rural roads.
Digitalisation and connectivity, new technology and new sensors have resulted in a wealth of new data that can complement traditional. Deep Learning and Machine Learning are methods that are suitable for analysis of state data. The decision on maintenance will be based on selected limit values. Too high or too low values entails both financial and security risks.
Modern efficient maintenance should build on objective data and take into account functional goals: to be traffic-safe, user-friendly and accessible.
