RISExploring Observed and Unobserved Preference Heterogeneity in Choice Behavior of Demand Responsive Customized Bus Service
Publisher: ASCE
Abstract: The users' taste preferences for the demand responsive customized bus (DRCB) and, in particular, the its mechanism of heterogeneity, which determine routing, timetabling, and even launch and cancellation of the DRCB service, ...
Material Strengthening Mechanisms and Their Contribution to Size Effect in Micro-Cutting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The specific cutting energy in machining is known to increase nonlinearly with decrease in uncut chip thickness. It has been reported in the literature that this phenomenon is dependent on ...
Experimental Investigation of a New Grid Cathode Design Method in Electrochemical Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the grid cathode design in electrochemical machining (ECM) in order to develop a new cathode design method for realizing a breakthrough: one cathode can produce different workpieces with different ...
Effect of Initial Density, Particle Shape, and Confining Stress on the Critical State Behavior of Weathered Gap-Graded Granular Soils
Publisher: ASCE
Abstract: Weathered gap-graded soils are a common geological body in mountainous regions, and they are widely used as construction materials. The shear strength is the controlling parameter for the design of civil projects; however, ...
Interlaminar Shear Performance of the Asphalt Pavement with Gravel Base Considering the Influence of Gravel Embedded Rate
Publisher: ASCE
Abstract: An asphalt pavement with gravel base (AP-GB) is used to alleviate the occurrence of reflective cracks. However, its interlaminar stability is affected by the gravel base’s looseness and interlaminar complex contact form. ...
Theoretical Solution for Stress and Strain Distributions Induced by Generalized Elastic Constant Variation in Rock Mass
Publisher: ASCE
Abstract: Rock formations experience strength and stiffness degradation or enhancement, which is often reflected by an increase or decrease in the elastic constant. Such elastic constant variation in rock mass often causes the ...
A Two-Stage Algorithm Based on Variable Distance Threshold for Estimating Alighting Stops Using Smart Card Data
Publisher: ASCE
Abstract: A reasonable method for estimating alighting stops can provide a data guarantee for schedule design and vehicle scheduling. However, few studies, to our best knowledge, have addressed this problem using the variable distance ...
Comprehensive Properties Evaluation of Modified Bio-Asphalt Mixture Based on Comparison Matrix
Publisher: ASCE
Abstract: The comprehensive properties evaluation index of asphalt mixture has the characteristics of multilevel and multifactor. The weight of each road performance index is the key factor to assess the comprehensive properties of ...
Progressive Collapse Resistance of Posttensioned Concrete Beam-Column Subassemblages with Unbonded Posttensioning Strands
Publisher: American Society of Civil Engineers
Abstract: In this study, the behavior of posttensioned reinforced concrete (PC) beam-column subassemblages subjected to the loss of a middle column is investigated experimentally. The influence of unbonded posttensioning strands ...
Study of Local Traffic Flow Fluctuation under Rainfall and Waterlogging with Characteristics of Dynamic Spatiotemporal Changes
Publisher: ASCE
Abstract: It is common knowledge that rainfall and rain-induced waterlogging have negative impacts on urban road traffic in that they could cause decreased traffic flow capacity and induce traffic congestion from a macroscopic view. ...
