Quantifying Wide-Body Vessel Navigation Delay in Narrow Waterways: A Case Study at the Houston Ship Channel
Publisher: ASCE
Abstract: In narrow waterways, navigation restrictions are imposed on vessels based on beam and length to safely accommodate two-way traffic. Each transit in a narrow waterway can potentially generate delay for the rest of the vessels ...
Railroad Track Geometric Degradation Analysis: A BNSF Case Study
Publisher: ASCE
Abstract: Planning and optimizing maintenance actions for rail failures are possible through understanding rail behaviors, which can be captured by statistical models. In this study, a degradation analysis of railroad tracks is ...
Imperfect Condition-Based Maintenance Strategy for a Deteriorating Rail Track System with Multiple Competitive Failure Modes
Publisher: ASCE
Abstract: This paper modeled rail track segments subject to multiple competitive failure modes and shock deterioration processes caused by passing trains. To determine the optimal inspection interval and intervention level of each ...
Traffic Simulation of Houston Ship Channel for Assessing the Impact of Waterway Closures on Vessel Waiting Time
Publisher: American Society of Civil Engineers
Abstract: In this study, a model was developed to simulate waterway operations in the Houston Ship Channel to estimate vessel waiting time during waterway closures and to determine the optimal closure scenarios. The model allows the ...
