This book was released on 2010 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance goals for a highway system are an indication of the desired system condition, and the level of service to be provided to its users. Setting the appropriate performance goals has a significant impact on the way highway agencies conduct business. With growing needs and limited resources, the consequences of setting different levels of performance goals should be examined and compared to optimize the highway infrastructure needs at the network level. Three interacting sets of costs are typically considered for a complete economic appraisal of highway projects: construction, maintenance and road use costs. Due to the shift in focus from design-and-build mode to the repair-and-maintain mode, this study focuses on maintenance related costs and the road user cost aspects only. Maintenance and rehabilitation activities on pavement infrastructure are ongoing processes that are required for the entire road network. This suggests that for long planning horizons and geographically extensive networks, their application usually results in significant financial needs. Typically, highway agencies have based their policy decisions such as the target condition levels for the system on the budget needs for maintenance and rehabilitation actions. Since in most cases, the funding needs exceed the available budget, the required preventive and routine maintenance activities suffer or are overlooked completely. Failure to timely apply these maintenance actions cause the pavements to deteriorate more rapidly into condition states that require for more expensive rehabilitation actions during the life cycle of the pavement. Over time, a vicious cycle is instigated in which the maintenance and rehabilitation needs of the network keep increasing each year. Although most highway administrators acknowledge the fact that pavement preservation is perhaps the most effective way of using the limited budgets available, the costs associated with deferring maintenance actions is oftentimes overlooked when establishing performance goals for the system. Road user costs in the form of costs for vehicle operation have been recognized as another large component of the total transportation related costs. These costs are then arguably the most important to consider for a complete economic appraisal. Ironically, they are also often disregarded while making important policy decisions. Other road user costs such as those related to the impact of traffic congestion and detours caused by construction and maintenance activities are difficult to quantify and were not accounted for in this study. Although it is widely accepted that establishing suitable performance goal is critical for system maintenance and preservation, a framework that considers the inter-relationship between conflicting objectives of minimum maintenance and rehabilitation costs, deferred maintenance costs, and vehicle operating costs to the users does not exist. This thesis proposes a methodological framework that is aimed at assisting highway agencies with the problem of objectively analyzing policy decisions in terms of the performance goals for their highway networks that would minimize the total transport costs to the society. In a case study of the proposed framework, the highway network managed by the Texas Department of Transportation was examined for different performance goals. The results from the case study indicate that setting lower performance goals lead to savings in the M & R needs, but at the same time, they also significantly increase the exogenous costs such as deferred maintenance costs and the vehicle operating costs.

Book excerpt: "This synthesis examines current performance-based management practices that are applied by state departments of transportation (DOTs) in highway maintenance and operations (M&O). Past studies have focused on the elements that make up a performance-based M&O approach, such as condition ratings, levels of service, performance measures, and threshold values. This study focuses on how state DOTs actually use performance-based measures to manage their highway programs."--Preface.

This book was released on 2024-05-23 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of sustainable road infrastructures has become an issue of concern to the international community. Road infrastructures require a large amount of non-renewable resources during the construction phase while containing abundant renewable energy resources (e.g. vehicle mechanical energy, internal thermal energy, and surface solar energy) during the operational phase. Therefore, reducing the dependence of road infrastructures on non-renewable resources, upgrading the construction and maintenance levels, improving the recycling level of infrastructure materials, and efficiently harvesting and utilizing clean energy from sustainable road infrastructures are of great significance in alleviating energy problems and promoting sustainable social development.

Available in PDF, EPUB and Kindle. Book excerpt: A practical guide that explains how we can design roads that are compatible with populations of small wildlife. Few of us think twice about driving on roads. Yet the very presence of roads and the act of driving on them can impact the ecological infrastructure that supports an animal's daily life. What chance does a turtle have of successfully laying its eggs when it needs to traverse a busy highway? Is it realistic to expect small mammals to breed when an interstate thoroughfare subdivides their population? These are the sorts of challenges faced by small, often slow-moving, animals, challenges that road engineers and ecologists are trying to address. For countless small species, vehicles traveling at high speeds are nothing less than missiles shooting across migration pathways. For too many animals, the danger can lead to the loss of populations, in part because they simply are not programmed to react to traffic. Salamanders faced with a two-lane road between the forest and their aquatic breeding site, for example, will typically cross that road regardless of the congestion. The result can be hundreds of flattened animals in a single night. Roads and Ecological Infrastructure is the first book to focus on reducing conflict between roads and small animals. Highlighting habitat connections and the challenges and solutions from both transportation and ecological perspectives, the volume covers various themes, including animal behavior related to roads and design approaches to mitigate the negative effects of roads on wildlife. The chapter authors—from transportation experts to university researchers—each promote a goal of realistic problem solving. Conceptual and practical, this book will influence the next decade or more of road design in ecologically sensitive areas and should prevent countless unnecessary wildlife fatalities.

Available in PDF, EPUB and Kindle. Book excerpt: Planning Sustainable Cities: An infrastructure-based approach provides an analytical framework for urban sustainability, focusing on the services and performance of infrastructure systems. The book approaches infrastructure as a series of systems that function in synergy and are directly linked with urban planning. This method streamlines and guides the planning process, while still highlighting detail, each infrastructure system is decoded in four "system levels". The levels organize the processes, highlight connections between entities and decode the high-level planning and decision making process affecting infrastructure. For each system level strategic objectives of planning are determined. The objectives correspond to the five focus areas of the Zofnass program: Quality of life, Natural World, Climate and Risk, Resource Allocation, Leadership. Developed through the Zofnass Program at the Harvard Graduate School of Design, this approach integrates the key infrastructure systems of Energy, Landscape, Transportation, Waste, Water, Information and Food and explores their synergies through land use planning, engineering, economics and policy. The size and complexity of infrastructure systems means that multiple stakeholders facing their own challenges and agendas are involved in planning; this book creates a common, collaborative platform between public authorities, planners, and engineers. It is an essential resource for those seeking Envision Sustainability Professionals accreditation.
