Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Conventional traffic congestion estimation approaches require the deployment of traffic sensors or large-scale probe vehicles. The high cost of deploying and maintaining these equipments largely limits their spatial-temporal coverage.  proposes an alternative solution with lor cost and wider spatial coverage by exploring traffic related information from Twitter. By regarding each Twitter user as a traffic monitoring sensor, various real-time traffic information can be collected freely from each corner of the city. Hover, there are two major challenges for this problem. Firstly, the congestion related information extracted directly from real-time tets are very sparse due both to the low resolution of geographic location mentioned in the tets and the inherent sparsity nature of Twitter data. Secondly, the traffic event information coming from Twitter can be multi-typed including congestion, accident, road construction, etc. It is non-trivial to model the potential impacts of diverse traffic events on traffic congestion.  propose to enrich the sparse real-time tets from two directions: 1) mining the spatial and temporal correlations of the road segments in congestion from historical data, and 2) applying auxiliary information including social events and road features for help.  finally propose a coupled matrix and tensor factorization model to effectively integrate rich information for  C itywide  T raffic  C ongestion  E estimation (CTCE). Extensive evaluations on Twitter data and 500 million public passenger buses GPS data on nearly 700 mile roads of Chicago demonstrate the efficiency and effectiveness of the proposed approach.
