Example Embodiment
[0086] Embodiment:
[0087] Short-term bus passenger flow prediction method based on weight stacking decision tree, such as figure 1 As shown, including the following steps:
[0088] The bus IC card data is obtained through the data acquisition device, and the bus IC card data includes passenger flow information and cardholder information;
[0089] Preprocessing the bus IC card data, extracts passenger flow feature information and card population feature information, and aggregates the bus IC card data into hourly passenger flow data;
[0090] Based on the location and historical passenger interval of the line to be predicted, the characteristic matrix is obtained, and the characteristic matrix is established and normalized; the predictive line feature data includes: hours, date, week, the first week , The first few days in the year, whether there is a holiday, the highest temperature, the lowest temperature, rainfall, and air index;
[0091] An independent test is performed betw
