چکیده

This work proposed an integrated model combining bagging and stacking considering the weight coefficient for short-time traffic-flow prediction, which incorporates vacation peak time features, as well occupancy speed information, in order to improve prediction accuracy accomplish deeper traffic flow data feature mining. To address limitations of a single forecasting, with ridge regression meta-learner is first established, then optimized from perspective learner using model, lastly embedded into new base obtain Ba-Stacking model. Finally, model’s shortcomings terms low utilization, information structure learners modified by weighting error coefficients while taking account external resulting DW-Ba-Stacking that can change weights adjust distribution thus utilization. Using 76,896 I5NB highway empirical study object, compared assessed traditional this paper. The results show has highest accuracy, demonstrating successful predicting short-term flows effectively solve traffic-congestion problems.

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

On short-term traffic flow forecasting and its reliability

Recent advances in time series, where deterministic and stochastic modelings as well as the storage and analysis of big data are useless, permit a new approach to short-term traffic flow forecasting and to its reliability, i.e., to the traffic volatility. Several convincing computer simulations, which utilize concrete data, are presented and discussed.

A GMDH-Based Traffic Flow Forecasting Model

Traffic flow forecasting, the core element of intelligent transportation system, plays an important role in traffic information services and traffic guidance. Since neural network prediction needs plenty of training samples, it cannot guarantee the real-timeness of traffic flow forecasting. In this paper, a GMDH network was constructed by self-organization, and the network was applied to traffi...
