Integrated Safety-Pavement Maintenance Management System (SPMS) for Local Authorities in Egypt

Abstract

Road maintenance management is a fundamental strategy for achieving the infrastructure sustainability. In Egypt, maintenance decision depends only on the pavement condition, and traffic safety is not considered. This study aims to develop an integrated safety-pavement management system that enables managing roads network according to the available funds and assures the safety concept throughout the service life of roads. It develops a probabilistic performance model and an optimization decision tool based on roads condition, safety levels, and maintenance costs to provide a proper maintenance decision. The system was validated for the road network in southern Egypt. Results show that an inadequate maintenance budget causes a decrease in safety levels and pavement conditions in some sections due to late maintenance decisions. However, the results indicate the applicability for determining the economic maintenance plan which keeps safety at the targeted level and enhances the pavement performance through the network by saving 27 million Egyptian pounds through the analysis period.
