Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Subway passenger flow prediction is strategically important in metro transit system management. The prediction under event occurrences turns into a very challenging task. ,  adopt a new kind of data source—social media—to tackle this challenge.  develop a systematic approach to examine social media activities and sense event occurrences. Our initial analysis demonstrates that there exists a moderate positive correlation beten passenger flow and the rates of social media posts. This finding motivates us to develop a novel approach for improved flow forecast.  first develop a hashtag-based event detection algorithm. Furthermore,  propose a parametric and convex optimization-based approach, called optimization and prediction with hybrid loss function (OPL), to fuse the linear regression and the results of seasonal autoregressive integrated moving average (SARIMA) model jointly. The OPL hybrid model takes advantage of the unique strengths of linear correlation in social media features and SARIMA model in time series prediction. Experiments on events nearby a subway station show that OPL reports the best forecasting performance compared with other state-of-the-art techniques. In addition, an ensemble model is developed to leverage the ighted results from OPL and support vector machine regression together. As a result, the prediction accuracy and the robustness further increase.
