Three-dimensional terrain has great influence on the air flying trail,different flying trail affect ATF to a large degree.

三维大地形对空中飞行航迹有很大的影响，不同的飞行航迹在很大程度上影响空中交通流量。

The paper studies on the method of traffic volume alteration fitted for Hebei provincial highway network ,carries on the modeling of the selection of flux observation point in OD back-stepping technique by the upper limit of maximum possible relative errors and the minimization of constrained domain,improves the precision of traffic volume alteration.

为研究适合于河北省公路网络的交通量更新方法，利用最大可能相对误差上限和约束域最小化对OD反推技术中的流量观测点选取进行建模，可提高交通量更新的精度，相关研究成果改善了河北省交通量预测模型，能很好地运用于河北省公路交通规划、管理和决策。

A congestion pricing model based on SUE and multi-destination choice was developed to decide the reasonable pricing level to lower their attraction, thus the traffic flow can be allocated statuesquely and the traffic facility can be used effectively.

城市交通网络中存在多个讫点，由于其知名度、居民的出行习惯等因素的不同，使其吸引力差异很大，某些讫点过度拥挤，某些讫点则流量不足。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
