Traffic Flow Data Collection Methods During Wildfire Evacuation

Fire and Materials, EarlyView.
ABSTRACT With climate change and urbanisation increasing wildfire risk in the wildland–urban interface (WUI), enhancing community evacuation preparedness is crucial. This study evaluates different data collection methods for measuring traffic flows during a community wildfire evacuation drill in Roxborough Park, Colorado, in June 2024.

Non-parametric probabilistic seismic capacity model for the stochastic interaction system of soil-subway station structures

Underground Space
A reasonable seismic capacity model is crucial for establishing the seismic performance level system and evaluating the seismic reliability of subway station structures.

Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, EarlyView.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

Characterising City Scale Heat Climatology for Australian Climate Zones

International Journal of Climatology, EarlyView.
The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Field Studies on the Influence of High‐Voltage Direct Transmission Underground Cables on Soils Along the SuedLink Route in Southwest Germany

Journal of Plant Nutrition and Soil Science, EarlyView.
During regular operation of the SuedLink at a load ≤75 %, the average increase in temperature in the plowing horizon is expected to be less than 1.6°C in the soils along the route in Southwest Germany. ABSTRACT Background The SuedLink was planned as a high‐voltage direct‐current underground cable route. The construction itself is a massive intervention

FANPCE technique for risk assessment on subway station construction

Journal of Civil Engineering and Management, 2019
Risk assessment is critical for the construction of the subway station to improve the risk management and reduce the additional loss. According to field investigation of safe construction, the analytical network process (ANP), fuzzy set theory and fuzzy ...

A comparison of monitoring methods for inferring demographics of a pond‐breeding amphibian population over 14 years

The Journal of Wildlife Management, EarlyView.
We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection. Abstract Long‐

Shaking Table Test of a Subway Station–Soil–Aboveground Structures Interaction System: Structural Impact on the Field

Buildings
The seismic design of underground or aboveground structures is commonly based on the free-field assumption, which neglects the interaction between underground structures–soil–aboveground structures (USSI). This simplification may lead to unsafe or overly

NUMERICAL ANALYSIS OF INUNDATION PROCESS IN UNDERGROUND SPACE CONNECTING TO A SUBWAY STATION

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2005
Inundation process in underground space which connecting to a subway station in urban area was studied numerically. Actual data sets of (1) road network, (2) drainage network and (3) underground space in the area around Shibuya Station were considered here, and a simplified numerical model was constructed. Based on the results of numerical computation,
