- Abstract: Non-recurrent and unpredictable traffic events directly influence road
traffic conditions. There is a need for dynamic monitoring and prediction of
these unpredictable events to improve road network management. The problem with
the existing traditional methods (flow or speed studies) is that the coverage
of many Indian roads is very sparse and reproducible methods to identify and
describe the events are not available. Addition of some other form of data is
essential to help with this problem. This could be real-time speed monitoring
data like Google Maps, Waze, etc. or social data like Twitter, Facebook, etc.
In this paper, an unsupervised learning model is used to perform effective
tweet classification for enhancing Indian traffic data. The model uses
word-embeddings to calculate semantic similarity and achieves a test score of
94.7%.
