Special Issue Information

Dear Colleagues,

Transportation is a sector that is not only essential for societal connectivity and economic growth, but is also a significant contributor to energy consumption and environmental impacts. To address these challenges, it is crucial for researchers and practitioners to actively explore innovative technologies and strategies that can effectively reduce energy usage in transportation systems. Consequently, this Special Issue will offer experts in the field a unique opportunity to share their most recent advancements, novel methodologies, and compelling case studies focused on energy-saving applications in transportation engineering. By fostering a collaborative environment for knowledge exchange and dissemination, this Special Issue aims to accelerate the development and implementation of sustainable practices in transportation and seeks to highlight the importance of integrating energy-saving approaches into transportation planning, design, and operation, ultimately leading to more efficient and environmentally friendly transportation systems.

In this Special Issue, original research articles and reviews are welcome and research areas may include, but are not limited to, the following topics:

  • Underground transportation infrastructure;
  • Deep excavation;
  • Energy saving in intelligent transportation systems;
  • Sustainable logistics and freight transportation;
  • Transportation system planning, optimization, and humanitarian logistics;
  • Artificial intelligence and machine learning applications in transportation;
  • Environmental methods in construction and maintenance;
  • Energy efficiency improvement in traffic infrastructure.

We look forward to receiving your contributions.

Archeological sites in humid regions are particularly susceptible to mechanical degradation induced by rainfall-driven wet–dry (W-D) cycles after excavation. In this study, representative archeological soils from the Suzhou region were investigated to quantify strength attenuation and pore structure evolution under cyclic moisture disturbance. Laboratory W-D cycling tests were conducted on samples prepared using static compaction and layered compaction methods, with cycle numbers up to nine and cycle amplitudes of 1–4 days. Unconfined compressive strength (UCS), direct shear strength, scanning electron microscopy, and mercury intrusion porosimetry were used for multiscale characterization. Results show that UCS decreases by approximately 40–50% after six to nine W-D cycles, accompanied by a porosity increase of 4.0–5.5% for statically compacted samples and 6.5–8.0% for layered-compacted samples. Layered-compacted specimens exhibit an average strength reduction of about 20% within the first three cycles, significantly higher than that of statically compacted soils. Microstructural observations reveal a progressive transformation from micropore-dominated structures (<10 μm, initially 70–80%) to interconnected meso- and macropores (>50 μm, up to 30–40%), leading to increased permeability (from ~10−8 to 10−6 cm/s). A semi-empirical model incorporating cycle number and amplitude successfully captures the non-linear evolution of porosity and strength degradation. These findings provide quantitative criteria for assessing excavation stability and long-term deterioration risks of archeological sites in humid environments. Full article
