Two-Level Integrated Optimization System for Planning of Emergency Evacuation
(American Society of Civil Engineers, 2006)This paper presents a two-level integrated optimization system for use in generating the candidate set of optimal evacuation plans that serve as the input for simulation-based evacuation systems. In the proposed system, ... -
Effect of Heavy Multiple Axle Trucks on Flexible Pavement Damage Using In-Service Pavement Performance Data
(American Society of Civil Engineers, 2006)Truck axle configurations and weights have changed significantly since the AASHO road study was conducted in the late 1950s and early 1960s. Emerging concerns about the effects of new axle configurations on pavement damage, ... -
Statistical Mixed Effects Models for Evaluation and Prediction of Accelerated Pavement Testing Results
(American Society of Civil Engineers, 2006)We elucidate the usefulness of the mixed-effects models in analyzing performance-type data resulting from accelerated pavement testing (APT) experiments. Our analysis is based on an APT test designed to evaluate the ... -
Automatic Speed Calibration Methodology for Traffic Monitoring Sites
(American Society of Civil Engineers, 2006)Traffic monitoring sites are installed in highways to collect speed, volume, and classification data to support various planning and intelligent transportation system applications. There is minimal research that addresses ... -
Louisiana Highway Evacuation Plan for Hurricane Katrina: Proactive Management of a Regional Evacuation
(American Society of Civil Engineers, 2006) -
Using Advanced Inspection Technologies to Support Investments in Maintenance and Repair of Transportation Infrastructure Facilities
(American Society of Civil Engineers, 2006)We present a statistically rigorous and computationally efficient framework that can exploit the extensive capabilities of advanced inspection technologies to support investment decisions in maintenance and repair of ... -
Discussion of “Intersection Construction Cost Functions for Alignment Optimization,” by Eungcheol Kim, Manoj K. Jha, and Paul Schonfeld

Safety Impacts of Differential Speed Limits for Trucks and Passenger Cars on Rural Interstate Highways: A Modified Empirical Bayes Approach
(American Society of Civil Engineers, 2006)To compare the safety effects of a uniform speed limit (USL) for all vehicles as opposed to a differential speed limit (DSL) for cars and heavy trucks, detailed crash data for six states were obtained for rural interstate ... -
Structural Adequacy of Flexible Pavements with Types and Widths of Shoulders
(American Society of Civil Engineers, 2006)Very little information is available on the role of the shoulders in respect to load carrying capacity and the performance of a flexible pavement. The present study aims at determining the effect of different types and ... -
Screening Tools for Considering Grade Separation at Rail-Highway Crossings
(American Society of Civil Engineers, 2006)At-grade rail-highway crossings lead to economic losses due to vehicle delays and train-vehicle collisions. To consider the need and priorities for grade separation at crossings, screening tools are required. Such tools ... -
Lessons From Katrina and Rita: What Major Disasters Can Teach Transportation Planners
(American Society of Civil Engineers, 2006) -
Optimal Transit Route Network Design Problem with Variable Transit Demand: Genetic Algorithm Approach
(American Society of Civil Engineers, 2006)This paper uses a genetic algorithm to systematically examine the underlying characteristics of the optimal bus transit route network design problem (BTRNDP) with variable transit demand. A multiobjective nonlinear mixed ... -
Comparative Analysis of Travel Impacts between the Design-Build and Traditional Building Methods
(American Society of Civil Engineers, 2005)A -
Structural Behavior of Cast In Situ Concrete Block Pavement
(American Society of Civil Engineers, 2005)This paper describes the findings of a study carried out for evaluating the performance of cast in situ concrete block pavements for low volume roads. Concrete is filled up into a formwork of cells -
Unified Design Method for Most No-Dig Rehabilitation Liners
(American Society of Civil Engineers, 2005)The liner materials used for pipe renovation are usually designed to meet some minimum consensus standards. Often, the design guidance is listed in the Appendix of the standards. For additional guidance, numerous design ... -
Multiobjective Vehicle Routing and Scheduling Problem with Time Window Constraints in Hazardous Material Transportation
(American Society of Civil Engineers, 2005)This paper proposes a novel vehicle routing and scheduling problem in transporting hazardous materials for networks with multiple time-varying attributes. It actually aims to identify all nondominated time-varying paths ... -
Modified Guidelines for Left-Turn Lane Geometry at Intersections
(American Society of Civil Engineers, 2005)Left-turn vehicles need sufficient sight distance to decide when it is safe to turn left and cross the lane(s) used by the opposing traffic. The current policy of the American Association of State Highway and Transportation ... -
Modeling of Strain Energy Absorbers for Rehabilitated Cracked Flexible Pavements
(American Society of Civil Engineers, 2005)The objective of this paper is to evaluate the potential use of a specially designed geocomposite membrane to delay the reflection of cracks in flexible pavement systems. Two-dimensional finite element models, which simulate ... -
Federal Highway Administration Vehicle Classification from Video Data and a Disaggregation Model
(American Society of Civil Engineers, 2005)To assess highway system performance, states are required to submit compositional traffic count reports to the Federal Highway Administration (FHWA). A methodology was developed for obtaining compositional vehicle counts ... -
Track Behavior in Curve Areas: Attempt at Typology
(American Society of Civil Engineers, 2005)In contrast to the usual descriptions of driving behavior in curve areas in terms of speeds, this research project investigated track behavior. In this connection, a classification of the driving processes according to the ...
