Lateral Distribution of Mixed Traffic on Two-Lane Roads
(American Society of Civil Engineers, 2006)Location of the outer wheel path is an important input in the measurement of deflection response of a pavement and its riding quality. In the simulation of mixed traffic flow, it is also required to assign the position of ... -
Improved Analysis Method for Wave-Induced Pipeline Stability on Sandy Seabed
(American Society of Civil Engineers, 2006)The existing Det Norske Veritas (DNV) Recommended Practice RP E305 for pipeline on-bottom stability is mainly based on the pipe–soil interaction model reported by Wagner et al. in 1987, and the wake model reported by ... -
Cost-Effectiveness of Railway Infrastructure Renewal Maintenance
(American Society of Civil Engineers, 2006)U.S. Class I railways maintain their infrastructure through a mix of ordinary maintenance and periodic renewal of infrastructure components. Different railways use different proportions of ordinary maintenance and periodic ... -
Difference between In Situ Flexible Pavement Measured and Calculated Stresses and Strains
(American Society of Civil Engineers, 2006)One of the 12 instrumented sections of the Virginia Smart Road was used to compare measured vertical compressive stress and measured transverse horizontal strain under the hot-mix asphalt (HMA) layer induced by a 25.8 kN ... -
Urban Bicycle Route Safety Rating Model Application in Jersey City, New Jersey
(American Society of Civil Engineers, 2006)Bicyclists consistently identify safety as one of their highest priorities in selecting bicycle routes. If transportation officials want to succeed in achieving the goal of increasing nonvehicular modes of travel, bicycle ... -
Model for Analysis of Factors Affecting Construction Schedule in Highway Work Zones
(American Society of Civil Engineers, 2006)In highway construction, it is not only important to understand the factors that affect the schedule but also to evaluate their probable severity and impact on project duration. However, there is currently no standard or ... -
Procedures for Calibrating TRANSYT Platoon Dispersion Model
(American Society of Civil Engineers, 2006)The paper demonstrates some inherent limitations of the TRANSYT software with regard to calibration of the recursive platoon dispersion model and, more specifically, modification of the travel time factor. Subsequently, ... -
Evaluation of the Trans-Texas Corridor Proposal: Application and Enhancements of the Random-Utility-Based Multiregional Input–Output Model1
(American Society of Civil Engineers, 2006)The Trans-Texas Corridor (TTC) projects a vision of 6,400 centerline km of new roadways and railways, intended to provide a faster, safer and more reliable means of transport for people and freight, while fostering economic ... -
Assessment of the Impact of Improvement Measures on Air Quality: Case Study of Delhi
(American Society of Civil Engineers, 2006)It is well known that the ambient air pollution attributable to road traffic depends on a number of factors such as the quality of fuel used, engine technology, driving conditions, emission control devices, and meteorological ... -
Prototype Time-Space Diary Design and Administration for a Developing Country
(American Society of Civil Engineers, 2006)Recent interest in developing activity-based models of transport demand has encouraged research on the design and administration of activity diaries. Activities occur in time and space. Traditionally, these two dimensions ... -
Evaluation of Speed-Based Travel Time Estimation Models
(American Society of Civil Engineers, 2006)Travel time estimation models, which rely on speed data provided from point detectors (usually inductive loops), have application in travel time prediction and network performance monitoring. Unfortunately there are limited, ... -
Issues and Solutions to Macroscopic Traffic Dispersion Modeling
(American Society of Civil Engineers, 2006)The paper improves upon the Yu and Van Aerde calibration procedure of the TRANSYT-7F platoon dispersion model, particularly for time steps greater than 1 s in duration, and develops three generalized platoon dispersion ... -
Operational Integration of Suburban Railway and Public Buses—Case Study of Mumbai
(American Society of Civil Engineers, 2006)In this research feeder routes and coordinated schedules were developed for integration of feeder public buses with suburban trains. A Heuristic Feeder Route Generation Algorithm was developed for generation of feeder ... -
Improved AADT Estimation by Combining Information in Image- and Ground-Based Traffic Data
(American Society of Civil Engineers, 2006)On most segments in a state highway system, annual average daily traffic (AADT) in the current year is estimated by applying an applicable growth factor to coverage count data obtained in an earlier year. The accuracy of ... -
3D FE Analysis of Flexible Pavement with Geosynthetic Reinforcement
(American Society of Civil Engineers, 2006)A series of finite element (FE) simulations are carried out to evaluate the benefits of integrating a high modulus geosynthetic into the pavement foundation. The simulations are conducted under a parametric study to ... -
Effect of Slab-Base Interaction on Measured Concrete Pavement Responses
(American Society of Civil Engineers, 2006)An experimental analysis of response data from actual aircraft passes at Denver International Airport was conducted to determine the effect of the slab-base interaction on concrete pavement responses. This analysis was ... -
Applying Method of Moments to Model Reliability of Pavements Infrastructure
(American Society of Civil Engineers, 2006)Even though the concepts of pavement reliability and risk-based design have been recognized for a long time, probabilistic pavement design methods are often limited to the application of Monte Carlo simulation or Taylor ... -
