The intersection shown here is to be analyzed using CMA. The following infonnation in available for this intersection: (a) PHF = 0.90. (b) Progression quality = Good (EB), Poor (WB), and Random (NB). (c) 5% HV in all movements, no local buses. (d) no pedestrians present (overpasses are provided). For the intersection as shown: (a) Analyze the intersection using the CMA Planning Approach. (b) Using the Operations and Design Approach, determine the existing vic ratio, delay, and level of service for each lane group in the intersection. (c) Aggregate the lane group delays for each approach and detennine the existing level of service for each. (d) Evaluate how well the intersection is operating, based on these results. If necessary, suggest changes in the physical design or signal timing that will result in better operations. It is not necessary to reanalyze the modififd intersection to demonstrate the effectiveness of the recommended improvements (e) Comment on the differences between the results of the Planning Approach and the Operations and Design Approach
