| dc.description.abstract | This thesis addresses the evaluation of operational performance of Gotera interchange in Addis Ababa and the relation between interchange performance measure and capacity in terms of level of service. The capacity and LOS of the interchange is analyzed and evaluated using three performance characteristics (Flow rate in pc/h/ln, Average passenger car speed and Density). The necessary geometric data for the analysis were obtained from Addis Ababa City Road Authority and site visit where as the available traffic movement data and free flow speed were collected on site. During traffic data collection 25 count stations were selected at which data was recorded for three hours time duration that had been carried out manually during at peak hours based on their vehicle class category, from which vehicles classified into heavy and light vehicles in order to compute percentage of heavy vehicles which is the main factors that affects hourly flow rate. Based on Capacity and Level of service analysis results, the current condition of interchange from 25 lines 12 lines have level of service of A and 7 lines have level of service of B, the rest 6 lines have LOS C and the line which carries maximum traffic flow is the main lines of the interchange flows Debre-Zeyt to Meskel- Square which is designated by D-M(P5-p8) carries 1,027pc/hr/ln and line which carries the least traffic flow is Bole to Debre-Zeyt designated by B-D(P10) which carries only 100pc/hr/ln. Results of merge influence of area also summarized as three merge areas have high flow rate from seven points that are towards Kera designated by exit of P12′ and P13′ and towards Meskel square designated by Exit of p3″and p1′ and Exit of p11′ have 2523, 2540 and 2426 pc/hr/ln respectively and all the three points have LOS of C. In the future after 10 years, LOS of the interchange lines will be between within A-F grade. One line will have A, four lines will have B, four lines will have C, five lines will have D, six lines will have E and five lines will have F. As shown as results of merge area, two merge influence area will have LOS of C, three will have D and two will have E, these influence area will have LOS E are exit of Meskel Square and Kera .Currently, the overall condition of the interchange is safe and to the future after 10 years, will not give a satisfactory service. | en_US |
