Pavement markings are essential elements of transportation infrastructure with critical impacts on safety and mobility. They provide road users with the necessary information to adjust driving behavior or make calculated decisions about commuting. The visibility of pavement markings for drivers can be the boundary between a safe trip and a disastrous accident. Consequently, transportation agencies at the local or national levels allocate sizeable budgets to upkeep the pavement markings under their jurisdiction. Infrastructure asset management systems (IAMS) are often biased toward high-capital-cost assets such as pavements and bridges, not providing structured asset management (AM) plans for low-cost assets such as pavement markings. However, recent advances in transportation asset management (TAM) have promoted an integrated approach involving the pavement marking management system (PMMS). A PMMS brings all data items and processes under a comprehensive AM plan and enables managing pavement markings more efficiently. Pavement marking operations depend on location, conditions, and AM policies, highly diversifying the pavement marking management practices among agencies and making it difficult to create a holistic image of the system. Most of the available resources for pavement marking management focus on practices instead of strategies. Therefore, there is a lack of comprehensive guidelines and model frameworks for developing PMMS. This study utilizes the existing body of knowledge to build a guideline for developing and implementing PMMS. First, by adapting the core AM concepts to pavement marking management, a model framework for PMMS is created, and the building blocks and elements of the framework are introduced. Then, the caveats and practical points in PMMS implementation are discussed based on the US transportation agencies’ experiences and the relevant literature. This guideline is aspired to facilitate PMMS development for the agencies and pave the way for future pavement marking management tools and databases.

Abstract: The objective of this article is to use a systematic review of the literature to answer how the maintenance sector considers the occupational safety and health (OSH) criteria, what impacts safety has on maintenance activities, which are the most significant branches of activities in this relationship, and which phases and types of maintenance are more prone to be influenced by OSH. The articles for these studies were selected through the Capes Portal, limited to the period between 2010 to 2015. Articles selected from the Brazilian Congresses on Asset Management and Maintenance in the period from 2013 to 2015 were also used. 38 articles were selected in total for the systematic review of the literature. The results were summarized through conceptual maps and revealed that there are fundamental relationships between OSH, Maintenance and Asset Management and that maintenance has a central role to play in these relationships. It is also concluded that the impacts of safety on the maintenance activities involve all stages of the process and that the maintenance sector considers the OSH criteria as a function of the safety of the persons performing the maintenance and operating the equipment. The contributions include a discussion on the importance of maintenance and safety according to different organizational cultures, the elements considered in management practices, maintenance strategies and safety criteria.

Three major power systems are described: The ‘inclusive' totalitarian system, the ‘non-inclusive' bureaucratic system, and the ‘exclusive' plan targeting system. The totalitarian system is aiming at controlling the whole population of a social system and based on resource exploitation. The bureaucratic system is aimed at information collection and decision making according to pre-established rules. The post-Taylor plan targeting system is aimed at determining and controlling the operative work of individual workers. As previous communist country experiences have shown, all three systems suffer from systemic constraints, that even if the three power systems are woven together, they are finally leading to the demise of a social system. Hope for change may come from moves towards cooperative management practices, as e.g. suggested by William Edwards Deming, and more complex theories with higher levels of integrity and complexity, as e.g. suggested by Steven Wallis, Foundation for the Advancement of Social Theory.
