Global Post-Evaluation for Highway Construction Projects

Abstract

The Post-project evaluation in highway construction is crucial but underdeveloped in infrastructure management, especially for Iraqi road project authorities. This comprehensive study combines insights from global schemes in England, Scotland, France, Australia, Norway, and New Zealand to develop a strong post-evaluation framework. This study used criteria from six international schemes, a thematic analysis framework, and open interviews with experts to identify and improve the final list of criteria that could be used in the evaluation process. Five criteria were identified as the final result, which are efficiency (cost, time, and quality), traffic analysis (volume, travel time, and impact), safety (accidents and security), sustainability, and impact (economic and social). Then, to develop a multiple regression model for the success of a project, criterion weights were derived through the utilization of the Inner Product Vector (IPV). This study emphasizes the need for a comprehensive post-evaluation framework, especially in complex highway construction. A milestone is reached when international standards and careful variable extraction are combined. Based on empirical data and expert judgment, the mathematical model simplifies assessment and predicts project success, giving stakeholders a systematic, impartial, and comprehensive evaluation tool.
