    Investigating City Growth Parameters For Emerging Towns In Ethiopia: The Case of adadi Mariam, Bishan Guracha, and Ginchi Towns In oromia Regional State.
    (Addis Ababa University, 2023-11-01) Gezu Yadete Kumbi; Berhanu Woldetensae (Associate Professor)
    Urbanization is a burning issue in developing countries like Ethiopia. However, the process does not happen all at once; rather, factors that occur gradually determine a city's spatial growth to attain its full capacity for expansion. Therefore, this study aimed to investigate growth-driving parameters and indicate ways of managing urban spatial growth in the emerging towns of Adadi Mariam, Bishan Guracha, and Ginchi in Oromia Regional State in Ethiopia. The methods applied for the study were a cross-sectional study using descriptive and explanatory research approaches to identify parameters contributing to spatial growth in these towns. Thirteen (13) parameters were developed and ranked using snowball sampling techniques. Eighty (80) questionnaires for Ginchi town, seventy-five (75) for Bishan Guracha, and sixty-five (65) for Adadi Mariam were used for each town. Then detailed interviews were conducted with six (6) key informants from each town to understand the top-five ranked parameters' level of influence over the last 20 years. The result showed that the top-five growth parameters of the towns vary. The existence of a tourist attraction center, the provision of market service, proximity to major towns, the addition of new education services, and a specialty in agricultural productivity were the top-five ranked parameters for Adadi Mariam, respectively. Land and housing rent value, political decision influence, proximity to major towns, proximity to industries, and land topography ranked 1-4, while climate condition and the existence of a tourism attraction center ranked 5th for Bishan Guracha. Similarly, transportation accessibility, provision of market service, location on the national road, provision of administrative services, and addition of new educational services are the top five identified growth parameters for Ginchi town. Generally, Adadi Mariam town is mainly a religious event and tourism-dependent town. Whereas, land value and politics due to its location between Hawassa and Shashemene towns influenced Bishan Guracha highly. Ginchi town mainly developed due to its transportation connectivity with many woredas and other towns. Thus, techniques and strategies based on an understanding of the potentials of each town and development gaps that strengthen growth parameters should be applied to help the growth of emerging towns.

    Investigating Spatial Accessibility of Public Transportation Network in Addis Ababa, Ethiopia: The Case of Bus Stations Along Mexico to Hayahulet Road Corridor
    (Addis Ababa University, 2024-05-01) Fiyameta Mulugeta; Berhanu Woldetensae (Associate Professor)
    This research paper investigates the spatial accessibility of public transportation networks in Addis Ababa, Ethiopia, using Geographic Information Systems (GIS) in the context of time and distance. It highlights the underestimation of nonmotorized travel and the need for accessibility-based planning to address road problems and low transport accessibility in developing countries. This research's main objective is to investigate the public transportation network's spatial accessibility in Addis Ababa, Ethiopia: the case of the Mexico to Hayahulet Route corridor. The methodology is particularly meticulous in terms of measuring the accessibility of bus stops, with a specific focus on walking distances regarded through the average comfortable walking paces and travel time to access different services and activities to be reached within a 15-minute walk. Based on the analysis the first method results illustrate, the existing Bus Stations from Mexico to Hayahulet are accessible to 31300 (62.6 %) individuals settled in 2.79 ha but less than half of the population in that area which is 18700 (37.72 %) individuals settled in 1.68 ha does not have an access to the specified road with a 500m travel distance standard. The accessibility based on time result showed that, around 68.5% of the population can access the bus stations within the standard limit whereas 31.5% of the population will have to walk an extra mile to access the nearest public bus stations. Further research should be conducted in other city areas to create a comprehensive view of public transport accessibility across Addis Ababa.

    Spatial Distrubution and Impact of Fuel Station on Traffic Flowi in Addis Ababa
    (Addis Ababa University, 2023-11-01) Natnael Habtemaryam; Berhanu Woldetensae (Associate Professor)
    As cities grow and expand traffic flow also increases in cities this phenomenon may results in traffic congestion which is a major problem for urban mobility. This research study investigated the spatial distribution and impact of fuel stations on traffic flow in Addis Ababa city. The study used both qualitative and quantitative approaches and other forms of data collection techniques. Names and street addresses of the filling stations were obtained from government bodies. Global positioning System (with in a mobile phone device) was used to capture the location of the filling station. Arrival rate of Vehicles, service rate and number of servers were acquired on field by keeping track of when cars arrived at Fuel Stations and the amount of time it took to serve each car. The geographical data were imported to Arc Map environment of ArcGIS 10.5 and analyses for spatial distribution were performed in the Arc Map environment using spatial statistics, spatial analyst and proximity tools available in the software. For the traffic impact analysis M/M/s queuing theory method is used. The findings revealed that there are 131 Fuel Stations in Addis Ababa and 75 Fuel Stations are found on PAS (Principal arterial street) road type, 40 Fuel Stations are found on SAS (Sub arterial street) road type and 16 Fuel Stations are found on CS (Collector street) road type Furthermore, utilizing the M/M/S Queuing System, the study reveals that traffic intensity in sampled Fuel Stations in the CS road type, SAS (Sub arterial street), and PAS (Principal arterial street) road types is significantly higher than one, indicating high demand. However, in CS (Collector Street) road type none of the stations have traffic intensity below 1. In contrast, 19 of the sampled 22 Fuel Stations in the SAS (Sub Arterial Street) road type have traffic intensity greater than one. The majority of Fuel Stations in the PAS (Principal Arterial Street) road type have traffic intensity less than one. Analysis from arc gis software showed that fuel stations along the city road are not evenly distributed, rather they are more concentrated together at different centers. In conclusion this Fuel Stations have a significant impact on the flow of traffic during rush hours. In light of these findings, the study recommends the development of urban planning standards, zoning regulations, and traffic impact assessments to optimize fuel station distribution. Operational Efficiency and Traffic Management Strategies are essential components of sustainable urban mobility in Addis Ababa City. Key Words: Fuel Station, Traffic Impacts, Spatial Distribution, Traffic Intensity, Queuing Model, ArcGIS.

    The Relationship Between Urban Spatial Structure and Travel Behavior of Residents in Addis Ababa
    (Addis Ababa University, 2023-08-01) Yididya Yoseph; Berhanu Woldetensae (Associate Professor)
    One of the pressing issues Addis Ababa currently facing is transportation and associated challenges. Different solutions such as the provision of LRT, public transportation, and widening of streets have been applied to minimize the challenges related to transport by the concerned sectors. However, these strategies were only able to bring temporary solutions. Therefore, understanding the relationship between activity densities and individual travel behavior is essential. Concerning this the paper aims to provide evidence on the relationship between the spatial structure and travel behavior in Addis Ababa in order to bring a more sustainable and resilient solution to the transportation and associated challenges. The study applies a mixed research design that combines both qualitative and quantitative data analysis. To increase the accuracy of data both primary and secondary data have been acquired, the primary data were collected through questionnaires and household surveys, While the secondary data were from relevant offices and websites. The collected data for spatial structure study are encoded on GIS and analyzed using GIS tools and Microsoft Excel spreadsheet while travel behavior data are analyzed using descriptive statistical methods. The findings initially identified the type of spatial structure Addis Ababa city has which is a mono-centric structure then calculated job-housing balance to select areas for travel behavior study which are from areas with high job-low housing, balanced job-housing, and low job-high housing ratios. Then from each area, we selected 128 participants a total of 384 using the purposive random sampling method. Finally, the research proved that spatial structure and travel behavior are related and areas that have a balanced job and housing ratio have a positive impact on travel behavior through the encouragement of sustainable modes of transportation, decreasing transportation expense as well as commuting time and its associated externalities. While areas with a low job–high housing have a more negative impact on travel behavior through their dependency on motorized vehicles, increased transportation expense, and a higher commuting time as well as increased VMT, CO2 emission, and energy consumption. Therefore, the balancing of jobs to housing should be a priority in the planning and design of cities along with the provision of affordable, quality, and mixed-income housing in different areas of a city.
