We have concluded five key tectonics geologic characteristics of Chinese foreland basins based on the study of the sedimentary infill, tectonics evolution, tectonic dynamics, spatial location distribution and structural deformation geometry.(1) The foreland basin is the superimposition of the compression sedimentary stratigraphic sequence with the extension basin, and the foreland basin includes underlying rift basin and upper dustpan flexure deposited basin.(2) The foreland thrustfold structural deformation has occurred four times since the Protozoic, in the Late Caledonian, Late Hercynian, Indosinan and Late Himalayan, respectively.(3) The foreland basin developed based on the control of two factors that are the basin basement collaged by many small plates or terrains and the rejuvenation of ancient orogenic belt, so the foreland basins or foreland thrusts are located in front of ancient orogenic belt.(4) The foreland basins and the rejuvenation of ancient orogenic belt make up a giant basinmountains system resulting from the distant effect of IndiaEurasia collision, which is located on the outer circle of Tibet Plateau, so the thrust deformation intensity, basin deposition range and coupling between orogenic belt and basin changed from strong to weak as from interior to outer circle of Tibet Plateau.(5) There are many structural styles of the thrust and fold belt in different basins, such as brittle behavior faultrelated fold, ductile behavior basementinvolved structure, basementinvolved faultrelated fold, and salt structure.

The major achievement of this paper is: Based on characteristics of the traffic data distribution, execute pattern recognition operations on traffic condition on two dimensions by clustering, then use BP neural network to describe and forecast traffic flow aiming at each pattern. Making use of classic flow-occupancy inverse "V" model, implement polynomial fitting using least-squares algorithm and statistics method on flow curves to detect outliers which are proved to be not accord with practice through the actual implement, then use the moving average model to recorrect the outliers and absent. Make correlation analysis on muti-direction flow queues of the intersection and ones of upriver intersections, choose flow queue with high correlation as assistant one to improve the error tolerance of the prediction system, at the same time we can use the method to give an estimation of flow in intersection with out sensors.
