Abstract: An optimization model is designed to guide pavement agencies to make decisions under multicriteria decision circumstances. In this paper, a multiobjective optimization model is illustrated to enable pavement-management ...

Abstract: This paper finds that pavement treatment short-term effectiveness in international roughness index (IRI) follows a polynomial relationship with a pretreatment pavement condition. Pretreatment pavement condition is an ...

Abstract: This paper provides information about railroad fuel efficiency. Two methods of estimating railroad fuel consumption are demonstrated: (1) an analytical procedure based on train resistance factors, speeds, changes in ...

Abstract: Deteriorated track infrastructure can lead to significant consequences, such as derailment incidents, loss of revenue-service hours, reduced train operation speed, and even failure of the business. The Federal Railroad ...
