Abstract
This research aims to probe the impact of transit-oriented development (TOD) on light rail transit efficiency at selected Addis Ababa Light Rail Transit (AALRT) stations (Ayat, CMC, Megenagna, and Mexico Stations). It studied the integration of transit-oriented development principle (density, diversity, design, and destination accessibility) into the AALRT, the impact of integrating TOD into AALRT on the ridership pattern or passengers flow, and a lesson from successful implementation of TOD on other cities. Both quantitative and qualitative research approach used to conduct this research. Likewise, both primary and secondary data source was used for this particular research. Observation and spatial analysis (GIS) used to generate the existing land use and road network map for the selected stations and the TOD principles were calculated using different formulas based on the existing land use and road network maps. Counting of sold tickets at peak hours, data from AALRT transport department, and structured interview was used to determine passengers flow at peak hours, average daily passengers, and passengers flow within the TOD influence zone respectively. Through a literature review, different cities’ successful TOD implementation experiences were studied. Purposive and availability sampling were used to choose an AALRT station to study and to determine passenger flow at peak hours. Spatial multi-criteria analysis and SPSS were used to analyze the TOD index and the relation between the TOD index and passenger flow. The research found that Ayat station is with better integration of TOD and Mexico station is with least TOD integration or TOD index. With high TOD index at all selected station within 800-meters TOD influence zone, the research concluded that TOD principle is more integrated within the 800-meters TOD influence zone than within 400-meters TOD influence zone. The passenger flow both daily passenger and passengers flow at peak hours has direct relation with the TOD index. Ayat station has the highest passenger flow daily and at peak hours correspondingly highest TOD index value. The passenger flow at peak hours doesn’t not affect by the distance to transit as the result demonstrate that majority of the trip is generated outside of the TOD influence zone. It shows that a dearth of affordable house within the TOD influence zone.
