RISOptimal Sampling of Infrastructure Condition: Motivation, Formulation, and Evaluation
Publisher: American Society of Civil Engineers
Abstract: Infrastructure management is the process through which inspection, maintenance, and rehabilitation decisions are made to minimize total life-cycle cost. Condition measurement, spatial sampling, and forecasting introduce ...
Computation of Infrastructure Transition Probabilities Using Stochastic Duration Models
Publisher: American Society of Civil Engineers
Abstract: Sound infrastructure deterioration models are essential for accurately predicting future conditions that, in turn, are key inputs to effective maintenance and rehabilitation decision making. The challenge central to ...
Uniform Infrastructure Fields: Definition and Identification
Publisher: American Society of Civil Engineers
Abstract: The present paper addresses the problem of assessing infrastructure condition using detailed spatial distress data. A new understanding of the spatial behavior of infrastructure distress is presented, and a condition ...
Sensitivity of Long-Term Infrastructure Condition to Initial Quality
Publisher: American Society of Civil Engineers
Abstract: Infrastructure condition throughout the lifetime of a facility is in part influenced by factors that are decided upon during initial design and construction. This paper presents a framework for exploring the sensitivity ...

Estimating Transit Route OD Flow Matrices from APC Data on Multiple Bus Trips Using the IPF Method with an Iteratively Improved Base: Method and Empirical Evaluation
Publisher: American Society of Civil Engineers
Abstract: An iterative method is proposed to estimate bus route origin-destination (OD) passenger flow matrices from boarding and alighting data for time-of-day periods in the absence of good
Simulation Laboratory for Evaluating Dynamic Traffic Management Systems
Publisher: American Society of Civil Engineers
Abstract: This paper presents a simulation laboratory for performance evaluation and design refinement of dynamic traffic management systems. The laboratory consists of four integrated components: (1) a traffic management simulator, ...
