Daily Cycles of Temperature-Independent Curvature in Jointed Plain Concrete Pavements
(American Society of Civil Engineers, 2017)Curvature due to temperature curling and moisture warping has a large effect on the performance and assessment of jointed plain concrete pavements (JPCP). Accurate curvature prediction can improve the design and evaluation ... -
Optimal Thresholds for Pavement Preventive Maintenance Treatments Using LTPP Data
(American Society of Civil Engineers, 2017)One obstacle to the optimal time for pavement maintenance treatments based on the expected performance or cost-effectiveness is the lack of posttreatment performance models at different timings. This study first summarized ... -
Torsional Effect on Track-Support Structures of Railway Turnouts Crossing Impact
(American Society of Civil Engineers, 2017)The introduction of special crossings and rail turnouts provides flexibility in the rail network as it allows for vehicles to switch between various tracks, thereby maximizing the utilization of current infrastructure. ... -
Comparative Study of Asphalt Pavement Responses under FWD and Moving Vehicular Loading
(American Society of Civil Engineers, 2016)This study aimed to compare pavement responses caused by impulsive dynamic loading and moving vehicular loading using mechanistic pavement analysis. Finite-element (FE) models were developed to simulate falling weight ... -
Mapping Overweight Vehicle Permits for Pavement Engineering Applications
(American Society of Civil Engineers, 2016)Oversize-overweight (OSOW) permit programs allow carriers to move large, heavy, and often high-value freight on state and federal highways. This study analyzed six years of Wisconsin single-trip overweight permits and two ... -
Road Roughness Evaluation by Curve-Fitting and Subspace-Identification Methods
(American Society of Civil Engineers, 2016)In this paper, for a quarter-car model, root-mean square response variables are calculated for roads classified by the international standard organization, based on the straight-line spectrum models. Covariance expressions ... -
Design and Predeployment Assessment of an Integrated Intersection Dilemma Zone Protection System
(American Society of Civil Engineers, 2016)Despite the fact that both traffic researchers and highway agencies have devoted considerable efforts over the past few decades to improving intersection safety, the development of effective strategies remains a challenging ... -
Condition Improvement Measurement Using the Condition Evaluation Criteria of Concrete Bridge Decks
(American Society of Civil Engineers, 2016)Maintenance, repair, and rehabilitation (MR&R) are cost-effective activities for maintaining good serviceability of concrete bridge decks during their lifetimes. Many past studies were conducted to provide public ... -
Merging Preparation Behavior of Drivers: How They Choose and Approach Their Merge Positions at a Congested Weaving Area
(American Society of Civil Engineers, 2016)Vehicle merging is a tactical process. In the existing merging models, drivers need to select a target gap and adjust their speed to reach a comfortable merge position to execute lane changing. However, such sequential ... -
Revised Guidelines for Designing Median Openings to Accommodate Simultaneous Left Turns
(American Society of Civil Engineers, 2016)When designing median openings at divided highway intersections, it is important to consider the impacts of simultaneous (noncrossing) left turning movements by vehicles from opposing directions. The AASHTO Green Book ... -
State-of-the-Art Model to Evaluate Space Headway Based on Reliability Analysis
(American Society of Civil Engineers, 2016)Stipulating a space headway is a pivotal concern in traffic engineering. Although consideration of a larger headway leads to safer traffic movement, consideration for a smaller headway can serve more traffic volume, which ... -
Multiobjective Optimization of Roadway Lighting Projects
(American Society of Civil Engineers, 2016)Roadway lighting systems play a major role in maintaining nighttime traffic safety as they reduce both the number and severity of nighttime traffic accidents. While the design of roadway lighting systems involves multiple ... -
Evaluation of 3D Automated Systems for the Measurement of Pavement Surface Cracking
(American Society of Civil Engineers, 2016)Pavement management systems rely on accurate distress measurements to support transportation agency officials in making decisions on budget planning and allocation as well as on the design of maintenance and rehabilitation ... -
Evaluation and Comparison of Real-Time Laser and Electric Sand-Patch Pavement Texture-Depth Measurement Methods
(American Society of Civil Engineers, 2016)In order to measure the texture depth of asphalt pavement automatically and accurately, a data set generated by a real-time laser pavement texture meter (RLPTM) was realized, and a calculation method was developed. Three ... -
Random Effect Models to Predict Operating Speed Distribution on Rural Two-Lane Highways
(American Society of Civil Engineers, 2016)This paper presents the results obtained from the estimation of free-flow speed on two-lane rural highways. The data used for the analysis were collected in Northwest Italy using video cameras and a laser speed gun. The ... -
Classification of Tours in the U.S. National Household Travel Survey through Clustering Techniques
(American Society of Civil Engineers, 2016)Tours are increasingly being considered as an appropriate unit of observation of mobility behaviors and are one of the key ideas underpinning contemporary activity-based modeling approaches. Identifying typologies of tours ... -
