Strategic Model to Optimize Railway-Track Renewal Operations at a Network Level
(American Society of Civil Engineers, 2016)This paper presents an optimization model for scheduling railway ballast, rail, and sleeper renewal operations at a network level. The objective of the model is to minimize the expected railway track life-cycle cost (LCC) ... -
Optimization of Transportation-Infrastructure-System Protection Considering Weighted Connectivity Reliability
(American Society of Civil Engineers, 2016)This study proposes a model and a solution method to optimize protection planning for transportation-infrastructure systems such as highway networks, which are subject to disasters given a limited budget. When links of a ... -
Performance Assessment of Secondary-Roadway Infrastructure in Iowa after 2011 Missouri River Flooding
(American Society of Civil Engineers, 2015)The Missouri River flooding in 2011 caused significant damage to secondary roadway infrastructure systems in western Iowa. This paper documents results of an investigation designed to evaluate unpaved roads and bridge ... -
Interferometric Stacking toward Geohazard Identification and Geotechnical Asset Monitoring
(American Society of Civil Engineers, 2016)Geotechnical assets are those found along transportation environments and are made up of or supported by earth materials. A geotechnical asset management program aims to achieve life-cycle performance goals by maintaining ... -
A Data-Driven Method for Comprehensive Pavement-Condition Ranking
(American Society of Civil Engineers, 2016)State highway agencies need pavement-condition data to select candidates for pavement maintenance and rehabilitation. However, it is a challenge for pavement engineers to simultaneously assess a number of attributes that ... -
Accounting for Censoring and Unobserved Heterogeneity in Pavement Cracking
(American Society of Civil Engineers, 2015)Most fatigue cracking models in use have been developed using the ordinary least squares (OLS) method. However, fatigue cracking data (or any type of cracking data) consists of censored data since it has a lower limit of ... -
Systematic Statistical Approach to Populate Missing Performance Data in Pavement Management Systems
(American Society of Civil Engineers, 2015)Transportation agencies use pavement management systems (PMS) for their maintenance and rehabilitation planning, programming, and budgeting. PMS is used to make decisions regarding when maintenance and rehabilitation should ... -
Agent-Based Information System for Electric Vehicle Charging Infrastructure Deployment
(American Society of Civil Engineers, 2015)The current scarcity of public charging infrastructure is one of the major barriers to mass household adoption of plug-in electric vehicles (PEVs). Although most PEV drivers can recharge their vehicles at home, the limited ... -
Holistic Analysis of Infrastructure Deterioration and Rehabilitation Using System Dynamics
(American Society of Civil Engineers, 2016)Rehabilitation programs are essential for efficiently managing large networks of infrastructure assets and sustaining their safety and operability. While numerous studies in the literature have focused on various aspects ... -
Road Infrastructure and Climate Change: Impacts and Adaptations for South Africa
(American Society of Civil Engineers, 2015)This paper presents the results of a study on the impact of climate change on road infrastructure in South Africa. The approach used built on previous work associated with the UNU-WIDER Development under Climate Change ... -
Precision Bounds of Pavement Distress Localization with Connected Vehicle Sensors
(American Society of Civil Engineers, 2015)Continuous, network-wide monitoring of pavement performance will significantly reduce risks and provide an adequate volume of timely data to enable accurate maintenance forecasting. Unfortunately, transportation agencies ... -
Utility Management System Cost and Time Benefits and Implications from the Local Agency Perspective
(American Society of Civil Engineers, 2016)Utility management systems (UMSs) have become more common for government agencies, and their use has recently been advocated by AASHTO on a statewide basis. By identifying current utility locations and correlating ... -
Improved Asset Management and Inventory Development through Sample Analysis and Vendor–Client Communication
(American Society of Civil Engineers, 2016)This study compared output from mobile inventory data collection vehicles to manually collected data techniques with a focus on two-way communications primarily through the submission of a sample data set to be analyzed ... -
Cumulative Effects on the Change of Residual Value in PPP Projects: A Comparative Case Study
(American Society of Civil Engineers, 2016)Public private partnerships (PPPs) have been adopted widely to provide public facilities and services. According to the PPP agreement, PPP projects would be transferred to the public sector. However, problems related to ... -
Road-Network Development in Quickly Growing Economies: Brazilian Case Study MG-050
(American Society of Civil Engineers, 2015)Governments throughout the world have been actively engaging in public–private partnership (PPP) arrangements to upgrade and develop their road networks. The transportation sector and particularly the road sector has ... -
Numerical Simulation of Multiple Step Transesterification of Waste Oil in Tubular Reactor
(American Society of Civil Engineers, 2016)Biodiesel is considered as a sustainable alternative to diesel fuel, as it can be utilized in current internal combustion (IC) diesel engine without any modification. It is transesterified from the combination of methanol ... -
Infrastructure Deterioration Prediction with a Poisson Hidden Markov Model on Time Series Data
(American Society of Civil Engineers, 2015)The deterioration of a pavement surface can be described in terms of the presence and severity of distinct distresses, like potholes, cracking, and rutting. Each deterioration process is ordinarily described by a set of ... -
