Hurricane Risk Assessment of Power Distribution Poles Considering Impacts of a Changing Climate
(American Society of Civil Engineers, 2013)Storm-related power outages cause approximately $270 million per year in repair costs in the United States. As a result of increasing sea surface temperatures caused by the changing climate, hurricane patterns (i.e., int ... -
Pavement Resurfacing Policy for Minimization of Life-Cycle Costs and Greenhouse Gas Emissions
(American Society of Civil Engineers, 2013)In recent decades, pavement management optimization has been designed with the objective of minimizing user and agency costs. However, recent analyses indicate that pavement management decisions also have significant impacts ... -
Evaluating the Use of Contractor-Performed Test Results in Highway Construction and Material Acceptance Decisions
(American Society of Civil Engineers, 2013)Transportation agencies around the world are using contractor-performed test results in construction and material acceptance and pay decisions. This practice is termed contractor acceptance testing (CAT) in this paper. ... -
Impacts of Climate Change on Scour-Vulnerable Bridges: Assessment Based on HYRISK
(American Society of Civil Engineers, 2013)More than 20% of the bridges in the United States were built more than 50 years ago, at a time in which intense precipitation events were much less common. However, very little work has been done on the use of scour ... -
New Approach for the Assessment of High-Speed Rail Projects and How to Contain Cost Overruns: Lessons from the EVA-TREN Project
(American Society of Civil Engineers, 2012)Cost overruns occur in the majority of transport infrastructure projects in the European Union. An average project is 15–20% over budget, and one in four is above that. Deviations in cost, duration, and environmental impact ... -
Comparison of Markov Chain and Semi-Markov Models for Crack Deterioration on Flexible Pavements
(American Society of Civil Engineers, 2013)There is a growing demand to preserve transportation infrastructure utilizing limited funds, and the modeling of flexible pavement deterioration has become an integral component of any pavement preservation model. Markov ... -
Cost-Benefit Analysis and the Optimal Timing of Road Infrastructures
(American Society of Civil Engineers, 2012)Standard cost-benefit analysis is based on a static setting, allowing the decision to be made of whether or not a new infrastructure should be built, but not allowing the conclusion to be made of if it would be preferable ... -
High-Speed Rail Opportunities around Metropolitan Regions: Madrid and London
(American Society of Civil Engineers, 2012)The original main aim of high-speed rail (HSR) was to link big metropolitan areas 400–600 km apart. Recently, intermediate HSR stations have also been created in suburban areas or small cities within the limits of metropolitan ... -
Empirical Data and Regression Analysis for Estimation of Infrastructure Resilience with Application to Electric Power Outages
(American Society of Civil Engineers, 2013)Recent natural disasters have highlighted the need for increased planning for disruptive events. Forecasting damage and time that a system will be inoperable is important for disruption planning. The resilience of critical ... -
Optimization-Based Regional Hurricane Mitigation Planning
(American Society of Civil Engineers, 2013)This paper introduces a constrained linear optimization model to help guide expenditure of government funds for regional hurricane risk management and to provide insight into some of the complexities involved in designing ... -
Urban Sprawl and Local Infrastructure in Japan and Germany
(American Society of Civil Engineers, 2012)Urban dispersion processes in metropolitan areas have led to patterns of suburbanization and urban sprawl. These processes are inseparably connected with the shift of private mobility from green transport modes to cars. ... -
Collecting Horizontal Curve Data: Mobile Asset Vehicles and Other Techniques
(American Society of Civil Engineers, 2013)Mobile asset data collection vehicles can provide transportation agencies with inventories of various roadway and roadside elements containing location information, element type, and condition data. Horizontal curves are ... -
Spending Scarce Funds More Efficiently—Including the Pattern of Interdependence in Cost-Benefit Analysis
(American Society of Civil Engineers, 2012)The financial crisis has substantially aggravated shortages of public funds all over the world, particularly in many developed countries. After the expiration of investments made within the framework of public economic ... -
Spatial Incidence of Economic Benefit of Road-Network Investments: Case Studies under the Usual and Disaster Scenarios
(American Society of Civil Engineers, 2012)Road networks can be considered local public goods. Hence, if they are to be efficient social choices from an economic perspective, their spatial benefit incidence should be equal to their cost burden in each region. An ... -
Rehabilitation of Aging Water Infrastructure Systems: Key Challenges and Issues
(American Society of Civil Engineers, 2012)Presented in this paper are the results of a state-of-the-practice survey on the rehabilitation of water distribution and wastewater collection systems. The survey identified several needs, including the need for rational ... -
Government Supports in Public–Private Partnership Contracts: Metro Line 4 of the São Paulo Subway System
(American Society of Civil Engineers, 2012)In November 2005, the state government of São Paulo, Brazil, announced the intention to bid a 30-year contract to build, operate, and explore passenger services for the Metro Line 4 of the São Paulo Metropolitan Subway ... -
Climate Change Influence on Priority Setting for Transportation Infrastructure Assets
(American Society of Civil Engineers, 2013)Transportation infrastructure could be vulnerable to local manifestations of global climate change, such as storm frequencies and durations of seasons. To adapt, transportation agencies need methodologies for reprioritizing ... -
Risk Allocation in Public–Private Partnership Infrastructure Projects in Developing Countries: Case Study of the Tehran–Chalus Toll Road
(American Society of Civil Engineers, 2012)All over the world, limited funding for the development and operation of infrastructure projects propels governments to attract private investment and enter public–private partnerships (PPPs). Different types of PPPs have ... -
