Life-Cycle Cost Minimization and Sensitivity Analysis for Mechanistic-Empirical Pavement Design
(American Society of Civil Engineers, 2012)Rebuilding and maintaining the nation’s highway infrastructure will require very large capital outlays for many years to come. While the expenditures involved in the maintenance and construction of highway facilities are ... -
United Kingdom Overlay Design of Flexible Pavement: Determination of the Important Parameters
(American Society of Civil Engineers, 2012)Pavement overlay is the most efficient form of material sustainability in road rehabilitation. In the United Kingdom and, perhaps, in most countries there is no standard approach for calculating the residual life of an ... -
Impact of Signal Timing Information on Safety and Efficiency of Signalized Intersections
(American Society of Civil Engineers, 2012)Signalized intersections are provided in traffic networks to improve the safety and efficiency of vehicular and pedestrian movement. Various measures under education, enforcement, and engineering headings being attempted ... -
Analysis of Conveyance System Use in Airport Concourses
(American Society of Civil Engineers, 2012)Airport terminal facilities continue to increase in size due to the trend of increasing demand at our nation’s regional and international airports. Airport operators have introduced various passenger conveyances including ... -
Development of Panel Rating Protocol and Condition Evaluation Model for Pervious Concrete Pavement
(American Society of Civil Engineers, 2012)Pervious concrete pavement (PCP) has the potential to provide significant technical, economical, and environmental benefits. To better understand the beneficial impacts of PCP, its performance must be comprehensively ... -
Critical Rut Depth for Pavement Maintenance Based on Vehicle Skidding and Hydroplaning Consideration
(American Society of Civil Engineers, 2012)Rutting is a major form of pavement distress in asphalt pavements. The main concern with rutting has been related to driving safety. Many highway agencies and researchers suggested that pavement rutting could lead to vehicle ... -
Drainage Modeling of Roadway Systems with Porous Friction Courses
(American Society of Civil Engineers, 2012)The conventional nonpermeable asphalt pavement interface significantly modifies relationships between rainfall and runoff while also altering the coupled transport of particulate matter (PM), heat, and solutes. This study ... -
Regime-Based Short-Term Multivariate Traffic Condition Forecasting Algorithm
(American Society of Civil Engineers, 2012)Predictions of fundamental traffic variables in the short-term or near-term future are vital for any successful dynamic traffic management application. Univariate short-term traffic flow prediction algorithms are popular ... -
Impact of Systematic Axle Load Measurement Error on Pavement Design Using Mechanistic-Empirical Pavement Design Guide
(American Society of Civil Engineers, 2012)In traffic characterization, axle load spectra (ALS) are one of the most critical inputs in the new Mechanistic-Empirical Pavement Design Guide (MEPDG). Axle load spectra have a significant effect on predicted pavement ... -
Reliable Statewide Pavement-Performance Study Using a Confidence Evaluation System
(American Society of Civil Engineers, 2012)There is an urgent need to develop a system to quantify survey data quality and to study pavement performance characteristics with levels of confidence. To address this need, a system is proposed to quantify historical ... -
Design with Fiber Reinforcement for Thin Concrete Overlays Bonded to Asphalt
(American Society of Civil Engineers, 2012)A thin concrete overlay bonded to asphalt pavement design approach has been developed by extending an existing ultrathin whitetopping (UTW) design method. A significant contribution to this proposed design method is the ... -
Local Calibration and Implementation of the Mechanistic-Empirical Pavement Design Guide for Flexible Pavement Design
(American Society of Civil Engineers, 2012)This paper presents the results of the calibration and implementation of the Mechanistic-Empirical Pavement Design Guide (MEPDG) for the design of flexible pavements in Italy. Local input data for traffic, climate, materials, ... -
Ramp Meters Evaluation: Using ITS Archived Data
(American Society of Civil Engineers, 2012)In December 2009, ramp meters along US 95 in Las Vegas between Rancho Drive and Craig Road were activated. A study was performed to quantify the benefits of ramp meters on the freeway mainline by using archived ITS data. ... -
Aerial Ropeway Transportation Systems in the Urban Environment: State of the Art
(American Society of Civil Engineers, 2012)The evolution of public transit modes has been remarkable, fueled by the need for different transit modes to handle different demand levels, urban environment patterns, and natural constraints and barriers. One of these ... -
Aircraft Response in an Airfield Arrestor System during an Overrun
(American Society of Civil Engineers, 2012)Air transportation has an overall outstanding safety record. However, accidents do occur. If an aircraft is unable to stop within the runway length, the incident is described as an overrun. To provide passenger safety ... -
Conventional, Flexible, and Variable-Type Bus Services
(American Society of Civil Engineers, 2012)To provide efficient public transportation services in areas with high demand variability over time, it may be desirable to switch vehicles between conventional services (with fixed routes and schedules) during peak periods ... -
Location and Depth of Pervious Concrete Clogging Material before and after Void Maintenance with Common Municipal Utility Vehicles
(American Society of Civil Engineers, 2012)In practice, it has been observed that the method of pervious concrete void maintenance depends on which machines or vehicles the owners have available. This research compares the abilities of three common municipal utility ... -
