Abstract

The implementation duration of road work is critical as it impacts both the cost and outcome of the project. The article examines the techniques used to determine the time required for the completion of road work projects.
It explores the approach to estimating the duration of road work projects in low- and middle-income countries
(LMICs) based on the ROCKS database created by the World Bank. The road work covers maintenance, rehabilitation and reconstruction (MR&R) activities. R programming is used for regression analysis of estimating the duration of road projects. The findings reveal that a 1% increase in project expense results in a 0.4% increase in project duration and that changes in the project area also affect the project duration. Additionally, a 1% rise in gross domestic product (GDP) per capita leads to a 0.05% decrease in project duration. It presents a thorough examination of the methodology used for estimating the duration of road projects in LMICs. The use of regression analysis as a method for determining project duration is proposed, and the results of the analysis indicate a strong correlation between project cost, project area, GDP per capita, and project duration.
