RISConnected Preceding Vehicle Identification for Enabling Cooperative Automated Driving in Mixed Traffic
Publisher: ASCE
Abstract: To enable the safe and fast formation of connected automated vehicle (CAV) platoons in real-world traffic, a preceding vehicle identification system for mixed traffic (PVIS-mixed) is proposed. PVIS-mixed utilizes the ...
Modeling a Car-Following Model with Comprehensive Safety Field in Freeway Tunnels
Publisher: ASCE
Abstract: Car following is the most common driving behavior in tunnels. However, current car-following models are not completely suitable for tunnels because they do not take into account the environmental factors affecting vehicles ...
Combined Impact of Alcohol-Fuel Properties on Performance and Emissions Characteristics with Low-Temperature Combustion in a Diesel Engine
Publisher: ASCE
Abstract: Low-temperature combustion (LTC) is a new combustion mode, and low cetane number fuels may be more appropriate for the LTC. Fuel properties play important roles both in the physical process of fuel-air mixing and the ...
Using Boundary Transform Method to Solve Geotechnical Problems with Mixed-Type Boundary Conditions
Publisher: ASCE
Abstract: In geotechnical engineering, mixed-type boundary problems cannot be solved directly by the integral transform method due to the diversity of boundary conditions. In view of this, the relationships between different boundaries ...
A Novel Integrated Method for the Risk Assessment of Ship-to-Ship LNG Bunkering Operations
Publisher: ASCE
Abstract: In recent years, liquefied natural gas (LNG) gradually has become an alternative fuel for ships. For targeted safety management of ship-to-ship LNG bunkering, this study developed a new method to identify, quantify, and ...
Effectiveness of Spent Coffee Ash in Concrete Permeable Pavement Bricks
Publisher: American Society of Civil Engineers
Abstract: This paper utilized the principle of circular economy to recycle spent coffee grounds, which are pyrolyzed into coffee ash biochar for the preparation of permeable concrete pavement bricks. This process can solve the problem ...
Optimal Configuration for Batteries and Chargers in Battery Switch Station Considering Extra Waiting Time of Electric Vehicles
Publisher: American Society of Civil Engineers
Combined Impact of n-Butanol Additive and Spark Timing on Combustion and Efficiency of a GDI Engine
Publisher: American Society of Civil Engineers
Abstract: The influence of n-butanol additive and spark timing on the combustion process was studied in a gasoline direct injection (GDI) engine, as well as fuel efficiency and relevant performance indicators. Three concentrations ...
Consolidation Theory of Unsaturated Soils with Vertical Drains Considering Well Resistance and Smear Effect under Time-Dependent Loading
Publisher: ASCE
Abstract: In this investigation, an approximate analytical solution to the axisymmetric consolidation problem of unsaturated soils improved with vertical drain is presented under the equal-strain condition. The smear effect of soil, ...
Semianalytical Solution of Consolidation of Composite Ground with Floating Impervious Column in Unsaturated Soil
Publisher: ASCE
Abstract: A novel semi-analytical solution is proposed to analyze the consolidation behavior of composite ground with a floating impervious column in unsaturated soil based on the equal-strain hypothesis. The basic governing equations ...
