Research on Relationships among Three Parameters in Short-term Traffic Flow Forecasting
This paper expects to get the real-time changes of traffic flow by researching the relationships among the three basic parameters flow, speed and occupancy, we firstly carries out the statistical correlation analysis and grey relational analysis to study the connection between the traffic flow parameters flow and speed, flow and occupancy to get a conclusion that there doesnt exist a significant linear relationship between neither of the comparisons, and the influence of speed on the flow is a little bigger than that of occupancy. Then we try to establish the binary linear regression model without the intercept and GM (0,3) model to do the data fitting, the final simulation results illustrate that the two methods has effects in some extent, also explain the complexity of traffic flow.
