Evaluation of Arterial and Freeway Interaction for Determining the Feasibility of Traffic Diversion
(American Society of Civil Engineers, 2011)Traffic congestion is a common phenomenon in our daily lives that greatly costs society. A better understanding of the interaction between freeways and arterial streets may help traffic engineers and researchers improve ... -
Assessing Casualty Risk of Railroad-Grade Crossing Crashes Using Zero-Inflated Poisson Models
(American Society of Civil Engineers, 2011)A railroad grade crossing (RGC) is a spatial location where rail and highway users share the right-of-way. A significant number of traffic crashes and severe consequences at RGCs have signaled the need for appropriate ... -
Effects of Temperature and Moisture Gradients on Slab Deformation for Jointed Plain Concrete Pavements
(American Society of Civil Engineers, 2011)Slab curvature, which represents the response of concrete pavement slabs to environmental loads, influences the location and magnitude of critical slab stresses and affects long-term pavement performance. The purpose of ... -
Multiobjective Optimization Model for Prioritizing Transit Stops for ADA Improvements
(American Society of Civil Engineers, 2011)Inaccessible transit stops prevent people with disabilities from using fixed-route transit services, thereby limiting their mobility. The Americans with Disabilities Act (ADA) prescribes the minimum accessibility requirements ... -
Simulation of Exclusive Truck Facilities on Urban Freeways
(American Society of Civil Engineers, 2011)This paper assesses the impact of exclusive truck facilities on urban freeway performance. A large-scale regional microscopic traffic simulation model is developed for morning and afternoon peak hours and is used to model ... -
Sampling and Analysis Methods for Estimation of Average Vehicle Occupancies
(American Society of Civil Engineers, 2011)Average vehicle occupancy (AVO) has been used in various applications, including conversion of person trips and vehicle trips in travel demand modeling, evaluation and monitoring of congestion management strategies, and ... -
Event-Based Modeling of Driver Yielding Behavior at Unsignalized Crosswalks
(American Society of Civil Engineers, 2011)This research explores factors associated with driver yielding behavior at unsignalized pedestrian crossings and develops predictive models for yielding by using logistic regression. It considers the effect of variables ... -
Road Barrier Repair Costs and Influencing Factors
(American Society of Civil Engineers, 2011)This paper presents a study that examines repair costs for different road barrier types and factors that influence these costs. The analyses focused on w-beam and cable barriers used as median barriers. To some extent, ... -
Evaluation of In Situ Pavement Material Properties and Behavior through Field Instrumentation and Load Testing
(American Society of Civil Engineers, 2011)State highway agencies have been experimenting with new concrete mixtures and pavement design features for improving the behavior and performance of concrete pavements. This paper presents the results of a field study ... -
Empirical Analysis of Commuters’ Nonwork Stop-Making Behavior in Beijing, China
(American Society of Civil Engineers, 2011)This paper presents a mathematical model to determine both a worker’s decision to participate in a nonwork activity and the decision about whether to include it in the basic home–work–home commute. By using household travel ... -
Empirical Method for Predicting Internal-External Truck Trips at a Major Port
(American Society of Civil Engineers, 2011)This paper presents a case study to explore the truck-trip generation model for hauling containers at a major international seaport. An internal-external truck-trip forecast model is examined. It incorporates influential ... -
Modeling Arterial Signal Optimization with Enhanced Cell Transmission Formulations
(American Society of Civil Engineers, 2011)This study presents an arterial signal optimization model that can consider queue blockage among intersection lane groups under oversaturated conditions. The proposed model captures traffic dynamics with the cell transmission ... -
Identification of Risk Factors Associated with Motorcycle-Related Fatalities in Ohio
(American Society of Civil Engineers, 2011)Ohio crash data for 2003–2007 were used to investigate the odds of a motorcyclist being fatally injured in a crash and the risk factors involved. The results show that risk factors for fatality/severe injury significantly ... -
Comparing Safety Performance Measures Obtained from Video Capture Data
(American Society of Civil Engineers, 2011)Safety performance is evaluated by using measures obtained experimentally from a videotaping of traffic operations at an urban roundabout situated in Cosenza, Italy. Five different expressions of safety performance from ... -
Motorcycle Characteristics for Sight Distance Investigation on Exclusive Motorcycle Lanes
(American Society of Civil Engineers, 2011)In developing Association of Southeast Asian Nations (ASEAN) countries, the motorcycle is a popular means of transportation because it is cheap and provides flexible door-to-door mobility. However, motorcyclists are also ... -
Greener and Leaner—Unleashing Capacity of Railroad Concrete Ties via Limit States Concept
(American Society of Civil Engineers, 2011)New knowledge has raised a concern about the cost-ineffective design methods and the true performance of railroad prestressed concrete ties. Because of previous knowledge deficiencies, railway civil and track engineers ... -
Cable Barriers and Traffic Safety on Rural Interstates
(American Society of Civil Engineers, 2011)High-tensioned cable barriers have been introduced in the United States as a median barrier option, primarily as a result of state agencies looking for a cost-effective means by which to mitigate or eliminate cross-median ... -
Evaluation of Driver Behavior in Type II Dilemma Zones at High-Speed Signalized Intersections
(American Society of Civil Engineers, 2011)Unlike traditional Type I dilemma zones, where inappropriate signal timings or detector placements restrict the ability of motorists to safely proceed through the intersection or safely stop in advance, Type II dilemma ... -
Impact of Driver Compliance on the Safety and Operational Impacts of Freeway Variable Speed Limit Systems
(American Society of Civil Engineers, 2011)Variable speed limit (VSL) systems enable freeway system managers to change the posted speed limit on a section of roadway in response to varying conditions. VSL system goals may include homogenizing traffic flow, improving ... -
Safety Impacts of Design Element Trade-Offs for Multilane Rural Highways
