RISSelecting Emergency Evacuation Routes in Urban Dynamic Traffic Network
Publisher: American Society of Civil Engineers
Abstract: We examined the selection of emergency evacuation routes in an urban traffic network with dynamic information. A method of selecting emergency evacuation routes was proposed based on the uncertainty characteristics of urban ...
Evaluation of Model-Based Soil Moisture Drought Monitoring over Three Key Regions in China
Publisher: American Meteorological Society
Abstract: AbstractLand surface models (LSMs) have been widely used to provide objective monitoring of soil moisture during drought, but large uncertainties exist because of the different parameterizations in LSMs. This study aims ...
Chaos Control of Freeway Mainline Using Variable Speed Limits with Fuzzy-Neural Networks Based on Subtractive Clustering
Publisher: American Society of Civil Engineers
Abstract: The chaos control of freeway mainline was studied by using variable speed limits and fuzzy-neural networks (FNNs) based on subtractive clustering. Based on the uncertainty and nonlinearity of a traffic system, the establishment ...
Coordinated Control Signal Input Strategies for Freeways
Publisher: American Society of Civil Engineers
Abstract: Strategies for inputting coordinated control signals in a freeway system are studied. Based on the symmetric, two - lane Nagel - Schreckenberg (STNS) model, a cellular automaton model of a coordinated control section on a ...
Four-Field Coupled Equation Correction of Hydrothermal Salt Force for Embankment of Coarse Particle Saline Soil and Its Experimental Verification
Publisher: ASCE
Abstract: This study aimed to elucidate the water–salt transfer mechanism, understand the effect of partition in the subgrade, and establish the relationship between water–salt transfer and salt expansion and thaw collapse in the ...
