The Integration Of Land Use And Public Transport System In Adama City, Oromia National Regional State, Ethiopia

Abstract

Public transport infrastructure in Adama city is not enough to meet the transport demand generated by the rapid growth of residential areas. As a result it generates vehicle trips leading to traffic congestion and costly roadway capacity improvements. Therefore, this research aims to understand the integration of land use and public transport system in Adama city. For identified public transport system analyses it uses international transport system evaluation standards, regression analysis, travel demand model, and local references by using questioners. Land use mix is calculated by measuring land use mix level using the Shannon diversity index and the extent of land use linking with travel using the Area index of a trip for each 8 traffic zone. Correlation analysis has been carried out to identify the relationship between the population density, land use mix level, and area index of the trip and understand the integration of land use and the public transport system. The research is mixed type research and was conducted using the deductive approach and descriptive in an explanatory manner. There are 13 public buses and 500 taxis (mini-bus) as a common public transport mode in Adama city. Public transport route covers 4.575% of total street network spatial coverage in Adama city, which is below standard according to the UN Inhabitants declaration in 2015. The travel demand model has been applied to 14 major 8 traffic zone which include 313 sub-8 traffic zones classified based on neighborhood block boundary and the result showed that there are 8 common trip generator 8 traffic zones and according to Utility Function and Multinomial Logit model, Public buses and taxis (mini-bus) had 95.6363% and 4.3636% of probability being chosen respectively. 8 traffic zone located nearby to the center of the city had a medium value of land use mix level ranging between 0.45 -0.65, while 6 8 traffic zone at a far distance from the city center and in the expansion area had a low value of land mix level below 0.45.The final analyses result showed land use mix level which indicate land use diversity and Area index of the trip which indicate travel behavior had a direct relation to each other. Generally it is recommended that, Adama city administration should include mixed-use development either or both vertical and horizontal methods and the transit oriented method in the city expansion strategy
