简介：交通控制和管理是有效措施解决交通拥挤的问题。为马路走廊的最佳的控制模型在事件条件下面被开发，它在每交叉并且在马路瓶颈节上在交通需求和能力之间的差别的平方的和的最小化形式。模型在斜面上在downstream在动脉的交叉，在在上游的离开斜面的离开斜面转向率和在斜面上转向率优化阶段裂口的控制参数。最后，客观功能被讨论，最佳的控制模型简单、实际，这被显示出。

简介：如果在上游的边界条件仅仅基于事件波浪被规定，时间依赖者当物理或假的反映的波浪变得重要时，数字模型不能有效地模仿波浪地。这份报纸小心地描述一条途径到指定条件与集合海绵层相结合向事件边界吸收反映的波浪的事件波浪边界。把数字模型合并了到一个时间依赖者，谁的管理方程是Boussinesq类型，途径的有效性详细被学习。一般边界调节，描述下面波浪边界条件也被概括到随机的波浪的盒子。数字模特儿详细被检查。测试用例包括常规的正常一个维的事件和二维的倾斜的事件常规波浪。计算结果证明现在的途径在向事件波浪边界抑制反映的波浪上是有效的。
