Abstract: Developing an optimal train speed profile for energy-efficient train operation is significant in both theory and applications but very difficult and complex to achieve. An optimization method that minimizes energy consumption ...

Abstract: Despite the high percentage of large truck trips on Interstate roadways, only 24% of fatal truck crashes occurred on these roadways. About 59% of large truck fatal crashes occurred on undivided highways that do not have ...

Abstract: Travel time prediction has been an interesting research area for decades during which various prediction models have been developed. This paper discusses the results and accuracy generated by different prediction models ...

Abstract: This study develops a time-driven train performance simulation (TPS) model consisting of train traction module, track alignment module, and train control module, which is applied to emulate the movement of a train, calculate ...

Abstract: An aerobic fluidized bed reactor process with internal media cleaning to control attached biomass thickness was developed. Biomass control was achieved by the periodic creation of a turbulent zone within a specially designed ...

Abstract: Disaster response in areas of high population density is centered on efficient evacuation of people and/or goods. Developing evacuation plans suitable for different levels of urgency based on the intensity of threat is a ...

Abstract: Work zones have become the second largest contributor to the nonrecurring delay disruptions of traffic on US highways. The development of a sound model to minimize the total cost (i.e., road user cost and agency cost) ...

Abstract: The United States relies on technology. To continue the development of new and the expansion of existing technologies requires a strong background in science, math, and engineering. Because students are falling behind in ...

Abstract: The goal of this study is to develop and apply a methodology for delineating optimal land-use patterns that minimize peak runoff flow at watershed outlets by coupling a hydrological model and a land-use model. Under the ...
