The sketch and specific design approaches of mid-block street crossing are generalized and three management and control modes are discussed. 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.
