Risk-Based Model for Pricing Highway Infrastructure Warranties
(American Society of Civil Engineers, 2009)Warranties have been used by many highway agencies in response to increased demand for including quality concepts in all phases of the highway life cycle and to guard against premature infrastructure failures. Currently, ... -
Formulation and Optimization of Robust Sensor Placement Problems for Drinking Water Contamination Warning Systems
(American Society of Civil Engineers, 2009)The sensor placement problem in contamination warning system design for municipal water distribution networks involves maximizing the protection level afforded by limited numbers of sensors, typically quantified as the -
Simulating Heterogeneous Traffic Flow on Roads with and without Bus Lanes
(American Society of Civil Engineers, 2009)Exclusive bus lanes are intended to enhance the level of service of bus transport in terms of speed, reliability, safety, etc. This paper is concerned with application of a newly developed microsimulation technique to study ... -
Budgeting Performance-Based Winter Maintenance: Snow Influence on Highway Maintenance Cost
(American Society of Civil Engineers, 2009)Swedish contracting of winter maintenance is combined with weather-regulated payment since the beginning of the 1990’s. It reduces the weather risk for the contractor and has helped performance-based specifications to find ... -
Transportation Infrastructure Planning, Management, and Finance

Efficient Use of Regional Transport Infrastructure, Communication Networks, and Human Capital
(American Society of Civil Engineers, 2009)Infrastructure capital can be considered a necessary condition to extend the regional production potential but not automatically a sufficient requirement for enhanced regional competitiveness and income. The materialization ... -
Road Cost Models for Prefeasibility Studies in Developing Countries
(American Society of Civil Engineers, 2009)In the early estimation there is compromise between the amounts of information available and accuracy of estimation. We propose three levels of analysis such as regional, country and project level for road cost models in ... -
Optimal Road Capacity Building: Road Planning by Marginal Cost Pricing
(American Society of Civil Engineers, 2009)The purpose of this study is to propose a new road planning and financing scheme based on short-term social marginal cost pricing that facilitates the establishment of optimal road standards in the long-term. We conducted ... -
Ten Years of World Bank Action in Transport: Evaluation
(American Society of Civil Engineers, 2009)Throughout the past decade transport projects have played a pivotal role in support of economic development and poverty alleviation. This evaluation, using objectives-based methodology, assesses the World Bank’s activities ... -
Pavement Marking Degradation Modeling and Analysis
(American Society of Civil Engineers, 2009)The objective of this research was to determine the performance characteristics of thermoplastic pavement markings in North Carolina and to create viable degradation models. Additionally, an evaluation of paint pavement-marking ... -
Managing Critical Infrastructure Interdependence through Economic Input-Output Methods
(American Society of Civil Engineers, 2009)Management of our critical infrastructures is a vital component of our economic and homeland security policy. The degree to which these infrastructures are interdependent, due to increasing system complexity and technology, ... -
Environmental Impacts over the Life Cycle of Residential Buildings Using Different Exterior Wall Systems
(American Society of Civil Engineers, 2009)This study analyzed the environmental impacts of a single-story residential building using different exterior wall systems. The environmental impacts over the complete life cycle of the residential buildings were determined ... -
Failure Assessment Modeling to Prioritize Water Pipe Renewal: Two Case Studies
(American Society of Civil Engineers, 2009)Studies indicate an urgent need to upgrade the nation’s aging and deteriorating water distribution systems so they can provide customers with reliable and safe water supplies. In response, water utilities apply performance ... -
Subway Station Diagnosis Index Condition Assessment Model
(American Society of Civil Engineers, 2009)Condition assessment of subway stations is a major issue facing public transit authorities worldwide. The Société de Transport de Montreal (STM) requires a rehabilitation budget of CAD 643.6 million (2006–2010) for its ... -
Practical Considerations in Statistical Modeling of Count Data for Infrastructure Systems
(American Society of Civil Engineers, 2009)Count data arise in a number of infrastructure assessment problems such as modeling traffic accidents, pipe breaks in water distribution systems, and electric power outages. A common goal in these problems is to model the ... -
Generic Methodology for Evaluating Net Benefit of Asset Management System Implementation
(American Society of Civil Engineers, 2009)Although transportation agencies in the United States have been developing asset management systems (AMS) as decision-support tools for specific types of infrastructure assets, there are several barriers to the implementation ... -
Data Management for Geospatial Vulnerability Assessment of Interdependencies in U.S. Power Generation
(American Society of Civil Engineers, 2009)Critical infrastructures maintain our society’s stability, security, and quality of life. These systems are also interdependent, which means that the disruption of one infrastructure system can significantly impact the ... -
Evaluating Environmental Impact in Water Distribution System Design
(American Society of Civil Engineers, 2009)An index-based method for the evaluation of the environmental impact of water distribution systems is introduced. The method is developed according to a set of methodological criteria to assess the environmental effect of ... -
GIS-Based Model for Highway Noise Analysis
(American Society of Civil Engineers, 2009)Elevated noise levels due to vehicular traffic are cause of grave concern in residential areas. They can significantly reduce property values. Most of the highway noise literature has been focused in predicting noise levels, ... -
Methodology for the Determination of Relative Weights of Highway Asset Management System Goals and of Performance Measures
(American Society of Civil Engineers, 2009)Of the overall benefits of a highway project, only a portion may be quantifiable in dollar values and the remaining in nondollar values. To facilitate project comparisons, both portions of project benefits need to be ...
