[0043] The present invention will be further described below with reference to the drawings and embodiments.
[0044] The present invention proposes a dynamic traffic demand estimation method using multi-source traffic data, such as figure 1 It is shown and applied to the travel of residents in a megacity in the south.
[0045] First construct the city’s traffic area, extract the real travel information of the residents through the city’s mobile phone signaling data, extract the residents’ real-time travel information through the city’s taxi GPS data and subway card swipe data, and then use the β( The value of i, j, tp) is divided into two resident travel modes with δ as the critical value, and different methods are used to estimate the real-time real-time travel of residents for different resident travel modes.
[0046] In this example, a large-scale crowd gathering activity in the city was taken as an example to verify the effectiveness of the real-time resident travel perception ...
