The present disclosure relates to system(s) and method(s) for generating an alert based on change in traffic pattern. The system receives historic traffic data and current traffic data, associated with each road segment, from a set of road segments. Further, the system identifies a change traffic pattern based on analysing the historic traffic pattern and the current traffic pattern, using data analytics and a machine learning algorithm. Furthermore, the system identifies a sub-set of road segments, from the set of road segments, based on comparison of the change in traffic pattern and a pre-defined threshold. The system further determines root cause of change in traffic pattern by analysing the sub-set of road segments. Further, the system generates an alert for updating one or more road segments, from the sub-set of road segments, based on the root cause of change in traffic pattern.
