Tabu Search Algorithm for the Railroad Blocking Problem
(American Society of Civil Engineers, 2013)The railroad blocking problem (RBP) is an important decision for freight railroad companies. The objective of this problem is to minimize the costs of delivering all commodities by deciding which interyard blocks to build ... -
Effects of Creep and Built-In Curling on Stress Development of Portland Cement Concrete Pavement under Environmental Loadings
(American Society of Civil Engineers, 2013)An adequate evaluation of stress developments in concrete is essential to ensure well-performing and long-lasting portland cement concrete (PCC) pavement designs and construction. In this study, the effects of creep and ... -
Rail Transit Route Optimization Model for Rail Infrastructure Planning and Design: Case Study of Saint Andrews, Scotland
(American Society of Civil Engineers, 2014)This paper is aimed at developing a rail transit route optimization model (RTROM) for cost-effective and sustainable rail infrastructure planning and design. Locations of rail transit routes and stations depend on many ... -
Potential Impacts of Longer and Heavier Vehicles on Texas Pavements
(American Society of Civil Engineers, 2013)This paper discusses the impacts of heavier and longer combination vehicles (LCVs) on the pavements of five major Texas corridors. These corridors were divided into 152 segments presenting uniform pavement properties and ... -
Calibration of Platoon Dispersion Parameter Considering the Impact of the Number of Lanes
(American Society of Civil Engineers, 2013)Microscopic vehicle behaviors, such as car following, overtaking, and lane changing, may occur differently on links with different numbers of lanes. Thus, this paper addresses the impact of the number of lanes on the platoon ... -
Pavement Treatment Short-Term Effectiveness in IRI Change Using Long-Term Pavement Program Data
(American Society of Civil Engineers, 2012)This paper finds that pavement treatment short-term effectiveness in international roughness index (IRI) follows a polynomial relationship with a pretreatment pavement condition. Pretreatment pavement condition is an ... -
Appropriate Regression Model Types for Intersections in SafetyAnalyst
(American Society of Civil Engineers, 2012)Highway agencies in the United States have started implementing SafetyAnalyst, highway safety management software. Some agencies have been developing or considering developing safety performance functions (SPFs) using local ... -
Self-Similar Behavior of Highway Road Traffic and Performance Analysis at Toll Plazas
(American Society of Civil Engineers, 2012)Until recently, the Poisson process has been used to model internet and road traffic queues. It has been established that internet traffic exhibits self-similarity, which is very different from the Poisson process. Motivated ... -
Quality Measures of Origin-Destination Trip Table Estimated from Traffic Counts: Review and New Generalized Demand Scale Measure
(American Society of Civil Engineers, 2012)The goals of this paper are to (1) provide a review of the recently developed measures for assessing the quality of origin-destination (O-D) trip tables estimated from traffic counts and (2) propose a new generalized demand ... -
Full Bayesian Method for the Development of Speed Models: Applications of GPS Probe Data
(American Society of Civil Engineers, 2012)Traffic speed is one of the basic variables that indicates the level of service of a road entity. It plays an essential role in transportation planning and management. This study attempts to establish a prediction model ... -
Performance Evaluations of the Spiral-Marking Roundabouts in Hong Kong
(American Society of Civil Engineers, 2012)The Hong Kong Transport Department initiated a trial of the spiral-marking system on four roundabouts in different phases between January 2004 and August 2008. In this study, observational and questionnaire surveys were ... -
Link-Journey Speed Estimation for Urban Arterial Performance Measurement Using Advance Loop Detector Data under Congested Conditions
(American Society of Civil Engineers, 2012)Travel speed ties directly to travel time, so it is an important measure for quantifying arterial performance. However, accurately estimating link travel speed for urban arterials is difficult because of traffic fluctuations ... -
Development of a VISSIM Simulation Model for U-Turns at Unsignalized Intersections
(American Society of Civil Engineers, 2012)The simulation of U-turns is currently of great interest to many transportation professionals due to the widespread use of indirect driveway left-turn treatments. In this study, a procedure was proposed to help transportation ... -
Differences in Driving Characteristics between Normal and Emergency Situations and Model of Car-Following Behavior
(American Society of Civil Engineers, 2012)This paper presents results of an exploratory study on differences in driving characteristics between normal and emergency situations and builds up the car-following model under the emergency evacuation situation. The ... -
Critical Assessment of Measuring Concrete Joint Faulting Using 3D Continuous Pavement Profile Data
(American Society of Civil Engineers, 2012)Faulting has traditionally been collected by using manual methods, which are labor intensive, time-consuming, and hazardous to workers and drivers. Therefore, alternative methods for effectively and safely collecting ... -
Network-Scale Traffic Modeling and Forecasting with Graphical Lasso and Neural Networks
(American Society of Civil Engineers, 2012)Traffic flow forecasting, especially the short-term case, is an important topic in intelligent transportation systems (ITS). This paper researches network-scale modeling and forecasting of short-term traffic flows. First, ... -
Operational Effects of Drivers’ Misperception of Horizontal Curvature
