Impact of Pavement Roughness on Vehicle Free-Flow Speed
(American Society of Civil Engineers, 2014)To investigate the impact of changes in pavement roughness on speed, this study developed a linear regression model to estimate free-flow speed on freeways in California. The explanatory variables include lane number, total ... -
Hybrid Method for Bus Network Design with High Seasonal Demand Variation
(American Society of Civil Engineers, 2014)Seasonal demand variation is a somewhat neglected aspect of transit demand. Many cities worldwide experience seasonal variation of passenger demand that deserves not only changes of service frequency, but also and often ... -
Optimal Recovery Plan after Disaster: Continuum Modeling Approach
(American Society of Civil Engineers, 2014)This paper presents an application of continuum traffic equilibrium model for the design of optimal recovery plan after a disaster. The continuum traffic equilibrium model is adopted for its strength in defining: (1) alternative ... -
Modeling Prework Trip-Making and Home Departure Time Choice
(American Society of Civil Engineers, 2000)This research develops a model of prework trip-making and home departure time choice. A nested logit model was found to be an appropriate approach. Data from the New York Metropolitan Statistical Area, collected as a part ... -
Use of Gravel Properties to Develop Arrester Bed Stopping Model
(American Society of Civil Engineers, 1991)This study was undertaken to investigate the engineering properties of a river pea gravel and to develop a model that can be applied to predict the stopping distance of runaway trucks in arrester beds. A summary of the ... -
Reliability of Underground Pipelines Subject to Corrosion
(American Society of Civil Engineers, 1994)The present paper is concerned with estimating the reliability of underground pipelines subject to externally applied loading and to corrosion, either externally or internally, or both. This affects the strength of the ... -
Pipe/Soil Stiffness Ratio Effect on Flexible Ipe Buckling Threshold
(American Society of Civil Engineers, 1989)Several types of low stiffness flexible pipe have been introduced in he United States in the past 10 years. Because of its extremely low pipe stiffness, very stiff embedment soil is required to limit pipe deflection to a ... -
Development of Feeder Routes for Suburban Railway Stations Using Heuristic Approach
(American Society of Civil Engineers, 2001)In this paper a heuristic algorithm is discussed for development of feeder routes to railway stations. The heuristic algorithm is a part of a model that has been developed for operational integration of suburban railway ... -
Asphalt Pavement Design: Highway versus Railroad
(American Society of Civil Engineers, 1984)The use of alphalt pavements as railroad trackbeds has received considerable attention in recent years. However, very little is known about the design of such pavements for railroad use. A comparison between highway and ... -
Discussion of “Fiber-Reinforced Fly Ash Subbases in Rural Roads” by Praveen Kumar and Shailendra Pratap Singh

Solution Structure for an Analytic Model of Bus Service Zones
(American Society of Civil Engineers, 2014)This paper points out questionable derivations for the formulated solution in the algebraic approach for the optimal length of local bus route of a traffic model for bus service zones. It also provides revisions for the ... -
Analytical Procedures for Estimating the Capacity of the Urban Expressway Section near Off-Ramps and On-Ramps with a Median Exclusive Bus Lane
(American Society of Civil Engineers, 2014)This paper presents a microsimulation approach for developing the analytical procedure for estimating the capacity of the urban expressway section near off-ramps and on-ramps with a median exclusive bus lane (XBL). First, ... -
Sensitivity of Flexible Pavement Thickness to Traffic Factors in Mechanistic-Empirical Pavement Design
(American Society of Civil Engineers, 2014)In an effort to minimize the risk of overdesign or underdesign of pavement structures in the -
Examining the Impact of Adverse Weather on Urban Rail Transit Facilities on the Basis of Fault Tree Analysis and Fuzzy Synthetic Evaluation
(American Society of Civil Engineers, 2014)The increasingly frequent extreme weather disasters caused by global climate change have attracted more attention to adverse weather’s effect on infrastructure systems. This paper aims to establish an integrated approach ... -
Highway Access Safety Program Evaluation with Uncertain Parameters
(American Society of Civil Engineers, 2014)Access management in transportation planning can reduce crashes, increase route capacities, and reduce travel times. The literature suggests a need for performance metrics and a decision-aiding framework to guide access ... -
Load Transfer Characteristics of Aggregate Interlocking in Concrete Pavement
(American Society of Civil Engineers, 2010)This paper presents a finite-element model of a jointed concrete pavement with aggregate interlocking load transfer system. Interlocking mechanism has been modeled by a set of discrete springs. A new parameter “modulus of ... -
Comparative Assessment of Traffic Control Parameters within an UTC-Distributed System
(American Society of Civil Engineers, 2014)Modern urban traffic control (UTC) systems are a key element of intelligent transportation systems (ITS). They represent the answer to the need of increased road network capacity and provide important benefits by reducing ... -
Impact of Abandoned and Disabled Vehicles on Freeway Incident Duration
(American Society of Civil Engineers, 2014)It is common to find a vehicle left on the shoulder, median, gore area, or on the travel lane for certain period of time. Experience from the state of Tennessee has shown that 78% of the freeway traffic-related incidents ...
