Empirical Bayes Approach for Estimating Urban Deer-Vehicle Crashes Using Police and Maintenance Records
(American Society of Civil Engineers, 2014)Deer-vehicle crashes are a growing problem in Iowa where deer-vehicle crashes represent 13% of all crashes reported. In 2009, these crashes resulted in nine fatalities and 451 injuries in the state. Deer-vehicle crashes ... -
Computer-Aided Design of Railroad Horizontal Arc Areas in Adapting to Satellite Measurements
(American Society of Civil Engineers, 2014)This paper presents a method of designing railway sections located in horizontal arcs. The adopted procedure is universal, i.e., it creates the possibility of varying both the type and the length of the assumed transition ... -
Decision-Making Process for Developing Urban Freight Consolidation Centers: Analysis with Experimental Economics
(American Society of Civil Engineers, 2014)The concept of freight consolidation center (FCC) has emerged in recent years. Although several case studies have indicated that FCCs are beneficial to the operation of urban transportation systems, the implementation of ... -
Model for Reducing Traffic Volume: Case Study of Belgrade, Serbia
(American Society of Civil Engineers, 2014)Daily congestion on transportation networks is the one of the biggest problems that city authorities face. Different strategies for transportation-demand management have been developed with the aim to decrease existing ... -
Exterior Roadside Noise Associated with Centerline Rumble Strips as a Function of Depth and Pavement Surface Type
(American Society of Civil Engineers, 2014)Controlled field studies were performed at 12 locations to evaluate the impacts of milled centerline rumble strips on exterior roadside noise adjacent to rural two-lane highways as a function of rumble strip depth and ... -
Estimation of Pavement Macrotexture by Principal Component Analysis of Acoustic Measurements
(American Society of Civil Engineers, 2014)A method is developed to estimate the mean texture depth (MTD) value, which to some extent represents pavement quality, using measurements from a microphone mounted underneath a moving vehicle. Such measurements will include ... -
Identifying Precrash Factors for Cars and Trucks on Interstate Highways: Mixed Logit Model Approach
(American Society of Civil Engineers, 2014)This research investigates the factors that lead to three manners of collision (namely, rear-end, angle, and sideswipe) that occurred in the same direction of multilane interstate highways. Mixed logit (MXL) models were ... -
Improving Systemwide Sustainability in Pavement Preservation Programming
(American Society of Civil Engineers, 2014)Highway agencies seek the participation of the private sector in pavement preservation, to raise revenue, share risks, and reduce project delivery costs. With public-private partnerships (PPP) representing an increasingly ... -
Assessment of Winter Maintenance of Porous Asphalt and Its Function for Chloride Source Control
(American Society of Civil Engineers, 2014)This study presents the findings from research conducted at the University of New Hampshire Stormwater Center (UNHSC) which investigated porous pavements as a potential strategy for minimizing the use of deicing chemicals ... -
Relationship between Predicted Speed Reduction on Horizontal Curves and Safety on Two-Lane Rural Roads in Spain
(American Society of Civil Engineers, 2014)According to different studies, speed reduction is considered one of the major factors in contributing road safety. For that reason, several guidelines have been recommended for maximum desirable speed reductions from ... -
Safety Impacts of Right-Turn Lanes at Unsignalized Intersections and Driveways on Two-Lane Roadways: Crash Analysis
(American Society of Civil Engineers, 2014)Safety benefits of right-turn lanes (RTLs) have typically been estimated on the premise that right-turn movements (RTMs) only lead to rear-end (RE) crashes, and RTLs completely eliminate such RE crashes. This premise is ... -
Unsaturated Soil Modeling for Airfield Pavement Design
(American Society of Civil Engineers, 2014)This study presents results of one of the first in situ assessment studies on the use of the Mechanistic-Empirical Pavement Design Guide (M-EPDG) methodology applied to the design of airfield pavements. The M-EPDG’s Enhanced ... -
Railroad Energy Efficiency in the United States: Analytical and Statistical Analysis
(American Society of Civil Engineers, 2014)This paper provides information about railroad fuel efficiency. Two methods of estimating railroad fuel consumption are demonstrated: (1) an analytical procedure based on train resistance factors, speeds, changes in ... -
Safety Analysis of Horizontal Curves Using Real Traffic Data
(American Society of Civil Engineers, 2014)Researchers are still seeking a better understanding of the parameters that affect safety in horizontal curves. Curves are one of the most critical sections of the road network contributing to a high percentage of serious ... -
Investigation of Material Improvements to Mitigate the Effects of the Abrasion Mechanism of Concrete Crosstie Rail Seat Deterioration
(American Society of Civil Engineers, 2014)Rail seat deterioration (RSD) continues to be identified as one of the primary factors limiting concrete crosstie service life in North America. RSD refers to the degradation of material at the contact interface between ... -
Evaluation Methodology for Laying Pattern of Interlocking Concrete Block Pavements Using a Displacement-Moment Concept
(American Society of Civil Engineers, 2014)Concrete block pavements (CBP) are increasingly used in pedestrian roads and low-volume highways. Concrete block pavements experience various failure modes, including shifting, cracking, spalling, and erosion of jointing ... -
Evaluation of Dynamic Message Signs on Rural Freeways: Case Study of a Full Freeway Closure
(American Society of Civil Engineers, 2014)The evaluation of dynamic message signs (DMSs) has been challenging to undertake because of the difficulty of identifying the effects of DMSs from traffic patterns. The primary contribution of this study is the comprehensive ... -
Diverging Diamond Interchange Analysis: Planning Tool
(American Society of Civil Engineers, 2013)Many traffic simulation software tools have emerged over the last decade and are widely used for analyzing capacity, delay, and level of service at intersections, ramps, and along arterial/freeway segments. Although these ... -
Mitigation of Ground Vibration Generated by High-Speed Trains on Saturated Poroelastic Ground with Under-Sleeper Pads
(American Society of Civil Engineers, 2014)Train-induced track and ground vibrations accelerate the deterioration of track, cause nuisance to nearby residents, and even damage adjacent structures. Past research has shown that under-sleeper pads (USPs) are effective ... -
