Multiobjective Approach to Long-Term Interurban Multilevel Road Network Planning
(American Society of Civil Engineers, 2009)This article presents a multiobjective approach to long-term interurban multilevel road network planning. In addition to the efficiency objectives dealt with in most of the literature where the subject is addressed, the ... -
Experience with Cable Median Barriers in the United States: Design Standards, Policies, and Performance
(American Society of Civil Engineers, 2009)A review of the experience of 23 states on the use and effectiveness of cable median barriers is presented. As of 2007, 23 states have installed more than 4,183 km (2,600 mi) of cable median barriers. Experiences of the ... -
Road Traffic Congestion and Crash Severity: Econometric Analysis Using Ordered Response Models
(American Society of Civil Engineers, 2010)There is an ongoing debate among transport planners and safety policy makers as to whether there is any association between the level of traffic congestion and road safety. One can expect that the increased level of traffic ... -
Evaluating the Cost Effectiveness of Flexible Rehabilitation Treatments Using Different Performance Criteria
(American Society of Civil Engineers, 2009)At a certain point in the life of a flexible pavement, rehabilitation is required to improve pavement condition and to defer reconstruction. Pavement managers seek the best rehabilitation treatment on the basis of cost ... -
Reset to Zero and Specify Active Safety Systems according to Real-World Needs
(American Society of Civil Engineers, 2010)Emergency brake assist, adaptive cruise control, and alternative instantiations of intelligent vehicle control systems aspire to support the driver in controlling the vehicle and alleviate the incidents that would lead to ... -
Aggregate Fuel Consumption Model of Light-Duty Vehicles for Evaluating Effectiveness of Traffic Management Strategies on Fuels
(American Society of Civil Engineers, 2009)The primary objective of this research is to develop a practical model for evaluating the effects of traffic management on fuel efficiency. The relationships between the real-world driving activities, the vehicle specific ... -
Review of Environmentally Conscious Transportation by Myer Kutz

Establishing the Weights of Performance Criteria: Case Studies in Transportation Facility Management
(American Society of Civil Engineers, 2009)Transportation management policies and practices are currently experiencing evolving trends such as funding limitations, aging facilities, greater travel demand, increased number of visible stakeholders, and higher user ... -
Population Synthesis with Subregion-Level Control Variable Aggregation
(American Society of Civil Engineers, 2009)This paper details the development of a fully customizable population synthesis program designed to be used for almost any geographic area or input variable. The design addresses several important issues that have been ... -
Artificial Neural Network Approach to Estimating Stiffness Behavior of Rubberized Asphalt Concrete Containing Reclaimed Asphalt Pavement
(American Society of Civil Engineers, 2009)Accurately predicting the stiffness of asphalt pavements is difficult due to the complex behavior of materials under various loading, pavement structure, and environmental conditions. This study explores the utilization ... -
Long-Term Speed Compliance and Safety Impacts of Rational Speed Limits
(American Society of Civil Engineers, 2009)In 2006, speeding-related crashes accounted for over 13,500 fatalities in the United States and many studies also indicate that speed and/or speed dispersion are a major cause of crashes on U.S. highways. This paper ... -
Illustrative Field Configuration and Evaluation of Traffic-Responsive Control
(American Society of Civil Engineers, 2009)Traffic-responsive plan selection (TRPS) control is one of the largely underutilized control features in National Electircal Manufacturers Association traffic controllers. This control feature allows the controller to ... -
Highway Project Level Life-Cycle Benefit/Cost Analysis under Certainty, Risk, and Uncertainty: Methodology with Case Study
(American Society of Civil Engineers, 2009)One of the key steps in the highway investment decision-making process is to conduct project evaluation. The existing project level life-cycle cost analysis approaches for estimating project benefits maintain limited ... -
Normalized Resilient Modulus Model for Subbase and Subgrade Based on Stress-Dependent Modulus Degradation
(American Society of Civil Engineers, 2009)The flexible pavement system consists of layered structures. Each layer is composed of different materials and represents different response to loading. Successful pavement design, therefore, requires proper evaluation of ... -
Using M∕M∕∞ Queueing Model in On-Street Parking Maneuvers
(American Society of Civil Engineers, 2009)This paper quantifies the influence badly parked vehicles and on-street parking maneuvers have on average link journey times as a function of the duration of the events and the number of designated maneuvers and flow, by ... -
Experimental Estimation of the Relative Deterioration of Surface Maintenance Treatments
(American Society of Civil Engineers, 2010)The performance of Australia’s unbound granular pavements with a wearing surface of stone aggregate embedded in a thin bituminous binder seal is highly dependent on maintaining a serviceable surface for the road users. ... -
Selecting Construction Measures for Mitigating Early-Age Delamination in CRC Pavements Made with Gravel Aggregates
(American Society of Civil Engineers, 2009)Gravel aggregates have been used extensively in the Houston District for continuously reinforced concrete (CRC) pavements construction for many years. However, some of these pavements have been subject to early-age ... -
Framework Development of Performance Prediction Models for Concrete Bridges
(American Society of Civil Engineers, 2009)Sound performance prediction models are essential for maintenance decision making in bridge management systems (BMSs). Markov chain models have been extensively used for performance prediction in BMSs. However, these models ... -
