The invention discloses a deep learning method for predicting urban traffic jam based on GPS, and relates to the field of intelligent traffic management. Through the deep learning method, a unsupervised large-scale urban network traffic jam prediction method (CRC3D) is innovatively constructed based on GPS real-time data on urban taxies. The method is characterized in that a recursion neural network (RNN), a convolutional neural network (CNN) and a three-dimensional convolutional neural network (C3D) are combined. The recursion neural network and the three-dimensional convolutional neural network can efficiently capture time-varying characteristics of continuous traffic states from different angles. The method is good in effect and high in practicability.

The invention discloses a liaison channel under airport taxiways, characterized in that it adopts a box body structure, and three-shaft cement blending piles are arranged in the groundsills under the airport taxiways below the box body structure and in the 20m-40m range on its two sides, there are attachment straps on its two sides, and the attachment straps are connected with the groundsills on its two sides, provided with three-shaft cement blending piles. In the specific engineering environment of airport, it reinforces the groundsills by three-shaft cement blending piles and can assure the strict differential settlement requirements of the airport.

A wheel speed measuring device for an aircraft braking system uses dual technology packaged in a single transducer that incorporates the robust and reliable variable reluctance technology along with a secondary package for measuring position and velocity bi-directionally for low speed and taxi operations. The transducer of the present invention is preferably incorporated into the envelope of the axle to allow both retrofit on existing aircraft and to maintain existing axle design and configuration.
