Based on extensive investigation and survey, the paper analysis the arriving laws in different land-use condition and the traffic characteristics of different crossing entities under different control modes. The initial characteristic, the speed and dispersion of the mobile flow are also intensive studied, as well as the effect of mid-block street crossing. Establish the linear planning models on the coordination between the signals of mid-block crossing and intersection. Finally the evaluation of the model output is carried out from time saving results, safety, economic results and social results. Set the example of Taiping north road in Nanjing, surveying the traffic situation, applying the method of signal coordination between the mid-block crossings and intersection to realize the south-to-north signal coordination design. The evaluation results show the coordination plan are more superior to the current signal plan.

根据对电极丝运动轨迹的控制形式不同，电火花线切割机床又可分为三种：一种是*模仿形控制，其在进行线切割加工前，预先制造出与工件形状相同的*模，加工时把工件毛坯和*模同时装夹在机床工作台上，在切割过程中电极丝紧紧地贴着*模边缘作轨迹移动，从而切割出与*模形状和精度相同的工件来；另一种是光电跟踪控制，其在进行线切割加工前，先根据零件图样按一定放大比例描绘出一张光电跟踪图，加工时将图样置于机床的光电跟踪台上，跟踪台上的光电头始终追随墨线图形的轨迹运动，再借助于电气、机械的联动，控制机床工作台连同工件相对电极丝做相似形的运动，从而切割出与图样形状相同的工件来；再一种是数字程序控制，采用先进的数字化自动控制技术，驱动机床按照加工前根据工件几何形状参数预先编制好的数控加工程序自动完成加工，不需要制作模样板也无需绘制放大图，比前面两种控制形式具有更高的加工精度和广阔的应用范围，目前国内外95％以上的电火花线切割机床都已采用数控化。
