Microsimulation Study of Effect of Volume and Road Width on PCU of Vehicles under Heterogeneous Traffic
(American Society of Civil Engineers, 2010)The traffic volume and roadway capacity are the important basic inputs required for planning, analysis, and operation of roadway systems. Expressing traffic volume as number of vehicles passing a given section of road or ... -
Strength and Deformational Characteristics of Foamed Bitumen Mixes under Suboptimal Conditions
(American Society of Civil Engineers, 2011)The effects of foamed bitumen contents on the strength and deformational behavior of foamed bitumen mixes used for road pavements is very complex and not fully understood yet. While some writers report an increase in ... -
Loads on Track, Ballast Fouling, and Life Cycle under Dynamic Loading in Railways
(American Society of Civil Engineers, 2010)In this paper a new method is presented for the estimation of actions on sleepers and the pressures that develop under the seating surface of the sleeper and are transmitted on the ballast. Results from laboratory tests ... -
Development and Empirical Study of Real-Time Simulation-Based Dynamic Traffic Assignment Model
(American Society of Civil Engineers, 2010)This research aims at developing a system of real-time simulation-based dynamic traffic model under mixed traffic flow conditions. The system consists of two layers, namely, simulation layer and real-time control layer. ... -
Comparative Analysis of Evolutionary, Local Search, and Hybrid Approaches to O/D Traffic Estimation
(American Society of Civil Engineers, 2011)This paper compares the performance of various advanced evolutionary algorithm (EA) techniques to solve the problem of dynamic origin/destination (O/D) estimation. The potential of EA in the dynamic O/D estimation problem ... -
Development of Nonlinear Railway Track Model Applying Modified Plane Strain Technique
(American Society of Civil Engineers, 2010)The contribution of ballast and subgrade layers behavior to railway track performance is given insufficient consideration in the current railway track models. In particular, stress- and traffic-dependent characteristics ... -
Influence of Platform Walking on BRT Station Bus Dwell Time Estimation: Australian Analysis
(American Society of Civil Engineers, 2010)The common approach to estimate bus dwell time at a Bus Rapid Transit (BRT) station platform is to apply the traditional dwell-time methodology derived for suburban bus stops. Current dwell-time models are sensitive toward ... -
Determination and Optimization of the Maintenance Frequencies in the Overhead Contact Line System
(American Society of Civil Engineers, 2010)This paper proposes a methodology to determine the optimum maintenance frequencies for the components of an electric railway overhead contact line system. This methodology is aimed at improving the reliability and availability ... -
Determination of the Transverse Resistance Characteristics in Railway Track
(American Society of Civil Engineers, 2010)The paper deals with transverse resistance problems occurring in railway ballast bed viewed from the standpoint of construction, maintenance, and safety of the railway track in use. Various ways of an analytical approach ... -
Influence of HOV Lane Access on HOV Lane Utilization
(American Society of Civil Engineers, 2010)High-occupancy vehicle (HOV) lanes are employed in many cities as a traffic congestion mitigation technique. These lanes are intended to provide a travel time benefit to carpools and buses, providing an incentive to choose ... -
Performance Evaluation of No Track Thermoplastic Traffic Markings
(American Society of Civil Engineers, 2010)No track thermoplastic is a relatively new thermoplastic traffic marking material which can be installed on newly constructed asphalt pavement shortly after finishing paving operations. The main objectives of this study ... -
Theoretical Framework for Modeling Pedestrians’ Crossing Behavior along a Trip
(American Society of Civil Engineers, 2010)Explaining pedestrians’ crossing behavior along entire trips may contribute toward more efficient and targeted planning of pedestrian facilities in urban areas and more accurate consideration of pedestrian safety. Although ... -

Simulation-Based Analysis of Train Controls under Various Track Alignments
(American Society of Civil Engineers, 2010)This study develops a time-driven train performance simulation (TPS) model consisting of train traction module, track alignment module, and train control module, which is applied to emulate the movement of a train, calculate ... -
Roadway Lighting Shows Safety Benefits at Rural Intersections
(American Society of Civil Engineers, 2010)Intersection-related crashes account for approximately 31% of fatal crashes in Minnesota and roughly 37% of those occurred at night, dusk, or dawn. Nationally, intersection-related fatal crashes accounted for 21% of all ... -
Free and Secure Trade Commercial Vehicle Crossing Times at the Pacific Highway Port of Entry
(American Society of Civil Engineers, 2010)At the Pacific Highway port of entry between the United States and Canada, typical delays are known to regional carriers and internalized into schedules. Due to their relative infrequency, the largest crossing times are ... -
Effect of Surrounding Traffic Characteristics on Lane Changing Behavior
(American Society of Civil Engineers, 2010)Lane changing maneuvers could have a substantial influence on traffic flow characteristics as a result of their interfering effect on surrounding vehicles. The interference effect of lane changing is more pronounced when ... -
What Is the Role of Multiple Secondary Incidents in Traffic Operations?
(American Society of Civil Engineers, 2010)Traffic incidents are a major source of travel uncertainty, imposing substantial costs on the transportation system. Sometimes, an incident can result in one or more secondary incidents, which can be particularly problematic. ... -
