Effectiveness Analyses of Flexible Pavement Preventive Maintenance Treatments with LTPP SPS-3 Experiment Data
(American Society of Civil Engineers, 2016)The present study analyzes the effectiveness of preventive maintenance (PM) treatments of flexible pavements utilizing data obtained from the specific pavement study 3 (SPS-3) of the long-term pavement performance (LTPP) ... -
Modeling Driver Compliance to VSL and Quantifying Impacts of Compliance Levels and Control Strategy on Mobility and Safety
(American Society of Civil Engineers, 2015)Variable speed limits (VSL) aim to improve freeway mobility and safety by influencing collective behaviors of drivers. Thus, VSL benefits should be positively correlated with the VSL compliance level (CL). Surprisingly, a ... -
Estimating Truck Aggressiveness Using a Multilinear Fatigue Model and a Viscoelastic Pavement Model
(American Society of Civil Engineers, 2016)To increase freight efficiency, trucks are allowed to transport heavier loads without adding extra axles. The impact of this practice on infrastructure damage needs to be evaluated. This involves evaluating the fatigue ... -
Effort Allocation in Rural Road Safety Analysis under Data-Limited Conditions
(American Society of Civil Engineers, 2016)Traffic safety policy defines plans that are expressed using numerical values for the planned level of improvement. The directing or apportioning of efforts represents the initial step of planned improvements. If a road ... -
Determination of Passenger-Car Units on Two-Lane Intercity Highways under Heterogeneous Traffic Conditions
(American Society of Civil Engineers, 2016)The introduction of the passenger car unit (PCU) concept by the 1965 edition of the -
Impact of Speed Limits and Road Characteristics on Free-Flow Speed in Urban Areas
(American Society of Civil Engineers, 2016)The paper documents studies of posted speed limit (PSL) changes on the free-flow speed on urban roads. Before and after field measurements were conducted, changing the existing PSL from 50 to 40 or -
Enabling Network-Wide Tolling-Strategy Assessment via Customized Route-Choice Simulation Module
(American Society of Civil Engineers, 2016)Tolling has been one of the most effective countermeasures against traffic congestion in metropolitan areas. Prior to the implementation of a tolling strategy, it was necessary to systematically evaluate the toll impacts ... -
Empirical Study of Lane-Changing Characteristics on High-Occupancy-Vehicle Facilities with Different Types of Access Control Based on Aerial Survey Data
(American Society of Civil Engineers, 2016)Research on lane-changing behavior has been active for decades because of its significant impact on traffic operations. Most of the existing studies focus on generic weaving sections (e.g., on-ramps), and very few of them ... -
Influence of Road Surface Characteristics on Tire–Road Noise for Thin-Layer Surfacings
(American Society of Civil Engineers, 2015)This study investigates the influence of different surface characteristics on tire–road noise of thin-layer road surfacings by a statistical modeling method. The surface characteristics considered are surface texture and ... -
Existing Bridge Formulas for Truck-Weight Regulation from International Jurisdictions and Resulting Load Stresses on Single-Span Bridges
(American Society of Civil Engineers, 2016)This paper identifies and characterizes existing bridge formulas from international regions and presents the results of an analysis of the allowable gross vehicle weights and bridge load stress effects on single-span bridges ... -
Effect of Red-Light Cameras on Capacity of Signalized Intersections
(American Society of Civil Engineers, 2016)Red light running (RLR) is one of the most common violations drivers commit at signalized intersections. To avoid RLR violations, some drivers may decide to stop abruptly, even though they had the opportunity to cross the ... -
Specifications of Fundamental Diagrams for Dynamic Traffic Modeling
(American Society of Civil Engineers, 2015)This paper studies different specifications of fundamental diagrams for first-order dynamic traffic modeling. The fundamental diagram, which refers to the relationship between traffic flow and density at a given location, ... -
Rail–Truck Multimodal Freight Collaboration: Truck Freight Carrier Perspectives in the United States
(American Society of Civil Engineers, 2015)Due to the impacts of highway congestion, truck driver shortage, the need for energy security, and the increasing revenue gaps to finance highway infrastructure construction and renewal, there is a critical need to explore ... -
Case Study of an Alternative Merging Sign Design for Temporary Traffic Control in Work Zones
(American Society of Civil Engineers, 2016)Signage plays an important role in work zones to provide guidance to drivers under changed conditions. This study investigated the safety effect of an alternative merge sign configuration in a freeway work zone. In this ... -
Intersection Control Considering Channelized Section Spillback Using a Flexible Phase Plan
(American Society of Civil Engineers, 2016)Large-scale traffic congestion often develops from local long queue in single intersections, accompanied by spillover. Current traffic control methods neglect the spillover effect, which may be one reason for the low ... -
Nonparametric Modeling of Vehicle-Type-Specific Headway Distribution in Freeway Work Zones
(American Society of Civil Engineers, 2015)This paper presents a vehicle-type-specific headway distribution analysis in a freeway work zone. The goal of this paper is to provide a vehicle-type-specific model with different time periods using empirical work-zone ... -
Assessment of Composite Pavement Performance by Survival Analysis
