Abstract :
the main objective of this paper is to compute flow appearances of the selected midblock and evaluate with various performance measures both in current and future condition conditions with basic considerations. Sidra Intersection 5.1 software used for the analysis and the result indicate that in average travel speed, variations perceived for all midblock. In future condition, South star-Godegohada midblock shows high deviation, which is 25.15% extra than Mobile-Areb sefer and 64.34% than Alamura-SNNPR Health Bureau midblock due to average delay, and cruise speed of the section. The degree of saturation, between 0.73-1.76 values for all midblock. In future condition, Mobile-Areb sefer midblock displays 50% increment in degree of saturation, which is 27.16% more than South star-Godegohada, and 31.69% than Alamura-SNNPR Health Bureau. In practical spare capacity, Mobile-Areb sefer and South star-Godegohada display negative value, which demand of flow is exceeding than the traffic flow carrying capacity. The future condition of Mobile-Areb sefer requires less in demand flow rate to equalize the above degree of saturation, which 102.52% lower than South star-Godegohada and 221.25% than Alamura-SNNPR Health Bureau midblock. In total effective capacity, based on adjusting total demand of flow and degree of saturation are declines for all midblock gradually. Mobile-Areb sefer is more 2.37 times than South star-Godegohada and 4.03 times than Alamura-SNNPR Health Bureau, midblock will decline in future condition. In demand of flow, deviation observed due to location of section, surrounding activities, condition of the road, configuration in traffic and pattern of traffic movement along those corridors.
