Estimated Lifetimes of Road Pavements in Sweden Using Time-to-Event Analysis
(American Society of Civil Engineers, 2014)Maintenance planning of road pavement requires reliable estimates of roads’ lifetimes. In determining the lifetime of a road, this study combines maintenance activities and road condition measurements. The scope of the ... -
Safety-Based Volume Warrants for Right-Turn Lanes at Unsignalized Intersections and Driveways on Two-Lane Roadways
(American Society of Civil Engineers, 2014)Safety-based volume warrants for right-turn lanes (RTLs) at uncontrolled major-road approaches to intersections and driveways on two-lane roadways were developed based on traffic crash and conflict analyses. Crash analysis ... -
Sustainable Toll Pricing and Capacity Investment in a Congested Road Network: A Goal Programming Approach
(American Society of Civil Engineers, 2014)This paper addresses the road toll pricing and capacity investment problem in a congested road network in a multicriteria decision-making framework. A goal programming approach is used in which the following four major ... -
Evaluating Snow and Ice Control Chemicals for Environmentally Sustainable Highway Maintenance Operations
(American Society of Civil Engineers, 2014)The use of chemicals and abrasives for highway winter maintenance operations is an essential strategy for ensuring a reasonably high level of service, yet the performance of such materials has to be balanced with their ... -

(American Society of Civil Engineers, 2014) -
Microscopic Estimation of Arterial Vehicle Positions in a Low-Penetration-Rate Connected Vehicle Environment
(American Society of Civil Engineers, 2014)Wireless communication among vehicles and roadside infrastructure, known as connected vehicles, is expected to provide higher-resolution real-time vehicle data, which will allow more effective traffic monitoring and control. ... -
Measuring the Performance of Bus Rapid-Transit Corridors Based on Volume by Capacity Ratio
(American Society of Civil Engineers, 2014)Various approaches have been deployed for evaluating the performance of bus rapid transit (BRT) systems based on qualitative, economic and quantitative parameters. In the present study, the performance evaluation of the ... -
Determining the Reasonable Scale of a Toll Highway Network in China
(American Society of Civil Engineers, 2014)This research aims to determine the reasonable scale of toll highways in China by considering factors including effects of non-debt investments; agency costs of construction, maintenance, and system operations; user travel ... -
Methodological Framework for Truck-Factor Estimation Considering Vehicle–Pavement Interaction
(American Society of Civil Engineers, 2015)Truck traffic is usually characterized by using truck factors (TFs). A TF converts a mixed truck traffic stream over the pavement design lifetime into a number of equivalent single-axle loads (ESALs). This conversion ... -
Calibration and Application of Treatment Performance Models in a Pavement Management System in Tennessee
(American Society of Civil Engineers, 2015)The usage of locally calibrated performance models and other related parameters is necessary in order to utilize the pavement management system (PMS) for maintenance strategy decision-making. In this study, the performance ... -
Development of an Electrophoretic Display Technology for Selectively Retroreflective Signs and Pavement Markers
(American Society of Civil Engineers, 2015)This paper describes an enabling technology that could be used to develop electronic roadway signs and markers whose display content can be changed and that are selectively retroreflective. This would give them the good ... -
Risk-Based Planning in Transportation Asset Management: Critical Pitfalls
(American Society of Civil Engineers, 2015)The 2012 transportation bill, Moving Ahead for Progress in the 21st Century, formalizes the application of risk management in transportation asset management decision making. The bill requires departments of transportation ... -
Assessing the Transferability of the Highway Safety Manual Predictive Method for Urban Roads in Fortaleza City, Brazil
(American Society of Civil Engineers, 2015)AASHTO’s Highway Safety Manual (HSM) provides guidance to safety professionals and is becoming a standard of practice, particularly for regions that require urgent action because of persistently high crash frequencies that ... -
Improved Imputation of Missing Pavement Performance Data Using Auxiliary Variables
