Socio-economic impacts of urban road dualization: Evidence from Ikare-Akoko, Nigeria

Purpose. This study examines the socio-economic impacts of urban road dualization in Ikare-Akoko, Ondo State, Nigeria, focusing on accessibility, economic activities, and quality of life for residents and business operators along the dualized corridor. Methodology. A multistage sampling procedure was employed, selecting five quarters through purposive and systematic random sampling. Data were collected from 170 household heads using structured questionnaires and analyzed through descriptive and inferential statistics (SPSS). Results. Road dualization generated mixed outcomes: positive effects included direct employment (22.4%), enhanced economic development (37.1%), reduced travel time and costs, and improved access to markets. However, significant negative consequences emerged, including property loss (62.9%), business displacement (81.2% lost customers), increased distance to destinations (92.9%), and elevated environmental costs (52.4%). Chi-square analysis confirmed a statistically significant relationship between road dualization and economic activities (χ² = 40.2, p < 0.05). Theoretical Contribution. This research contributes to urban transport geography and infrastructure development literature by demonstrating the dual nature of road dualization impacts in developing urban contexts, highlighting the need for integrated planning frameworks that balance infrastructure modernization with social equity. Practical Implications. Findings recommend complementary infrastructure development (shopping centers, utilities), improved urban planning standards to minimize property displacement, sustainable road maintenance policies, and public education programs on proper road usage to maximize socio-economic benefits while mitigating adverse effects.
