摘      要:Like many other economic and social activities that are infrastructure-intensive, the transport sector is an important component of the economy impacting on national, regional and local development as well as the welfare of citizens. An efficient transport infrastructure provides a multitude of socioeconomic opportunities and benefits with positive multiplier effects such as better accessibility to markets, employment, education and health. If it is well managed, transport infrastructure transforms the quality of life of residents through dynamic externalities it generates. But when infrastructure is deficient in terms of capacity, efficiency or reliability, it can have unwarranted economic costs due to reduced or missed opportunities. Despite its central role in rural development, little is known about the extent and impact of the various benefits that arise from the development of roads, particularly in developing countries. A large body of literature exists documenting the spatial patterns of socioeconomic development which can be induced by road infrastructure development processes and are in most cases dynamic and temporal. The impacts of a given road infrastructure development can also be analysed at the local, regional or national perspectives. The local impact is expected to be limited to the immediate neighbourhoods of the highway including tukuls, towns and villages to be found on both sides of the road within a distance of 5kms defining the influence zone. Based on this, the main objective of this research is to assess socioeconomic impacts of road infrastructure development of three newly developed highways on their respective surrounding communities 5-10 years after the interventions. Two of the highways are gravel surfaced and one is paved type. The respective study names are: Gendewuha – Gelago road (Corridor 1), Mile – Weldiya road (Corridor 2) and Ginchi – Kachisi road (Corridor 3). Their respective lengths are 165; 125; and 105 kilometres, while th
