Upgrading Arc Median Shortest Path Problem for an Urban Transportation Network
(American Society of Civil Engineers, 2009)In this paper, we propose an algorithm for an upgrading arc median shortest path problem for a transportation network. The problem is to identify a set of nondominated paths that minimizes both upgrading cost and overall ... -
Pilot Car Wait-Time Notification System
(American Society of Civil Engineers, 2009)The Kansas Department of Transportation does routine roadwork that requires traffic on two-lane highways to be narrowed to one lane. This operation usually involves use of a pilot car to direct the flow of traffic. The ... -
Effect of Compaction Mode on the Mechanical Performance and Variability of Asphalt Mixtures
(American Society of Civil Engineers, 2009)This paper investigates the relationship between mode of asphalt mixture compaction and resulting mechanical performance in terms of stiffness modulus, permanent deformation and fatigue resistance. Four modes, comprising ... -
Integration of Moisture Sensitivity Testing with Gyratory Mix Design and Mechanistic-Empirical Pavement Design
(American Society of Civil Engineers, 2009)Moisture damage is one of the major problems that can be faced by a pavement during its design life. It can tremendously reduce a pavement’s strength and consequently its life. The test predominately specified to evaluate ... -
Improved Flow-Based Travel Time Estimation Method from Point Detector Data for Freeways
(American Society of Civil Engineers, 2009)Travel time is an important parameter in evaluating the operating efficiency of traffic networks, in assessing the performance of traffic management strategies, and as input to many intelligent transportation systems ... -
Pullout Resistance Characteristics of Cast Iron Pipe
(American Society of Civil Engineers, 2009)Cast iron pipe came into heavy use during the latter half of the 19th century and numerous utility companies formed extensive pipeline networks using cast iron pipes until 1940s. Later cast iron pipe was superseded by ... -
Effects of Varying Functional Classification on Cost of Roadways
(American Society of Civil Engineers, 2009)Weakened purchasing power and dwindling funds are causing transportation agencies to rethink their engineering practices in order to achieve more cost-effective designs. Increasing public awareness of the impact of highway ... -
Potential Applications of Nanotechnology in Pavement Engineering
(American Society of Civil Engineers, 2009)Nanotechnology is the term used to cover the design, construction, and utilization of structures with at least one dimension measured in nanometers. Compared with typical civil engineering structures, the two fields operate ... -
Simulation-Based Investigation on High-Occupancy Toll Lane Operations for Washington State Route 167
(American Society of Civil Engineers, 2009)High-occupancy toll (HOT) lane operation has been implemented in several urban areas in the United States and is regarded as one of the most effective management strategies against freeway congestion. By allowing single ... -
Desired Time Gap and Time Headway in Steady-State Car-Following on Two-Lane Roads
(American Society of Civil Engineers, 2009)Two continuous statistical distribution models, gamma and lognormal, are proposed for desired time gap -
Crash Injury Severity Analysis Using Bayesian Ordered Probit Models
(American Society of Civil Engineers, 2009)Understanding the underlying relationship between crash injury severity and factors such as driver’s characteristics, vehicle type, and roadway conditions is very important for improving traffic safety. Most previous studies ... -
Simulation-Based Study on a Lane-Based Signal System for Merge Control at Freeway Work Zones
(American Society of Civil Engineers, 2009)This paper presents a new lane-based signal merge (LBSM) control system for freeway work zone operations. The proposed system applies the signal control concept to regulate the vehicles passing the work zone area at a ... -
Climate Change Implications for Flexible Pavement Design and Performance in Southern Canada
(American Society of Civil Engineers, 2009)Two types of analysis were conducted to examine the impacts of midcentury scenarios of anthropogenic climate change on flexible pavement infrastructure in southern Canada. An analysis of deterioration-relevant climate ... -
