Identifying dangerous lane-change behavior through coupled lateral–longitudinal interaction risk assessment

Dangerous lane changes in urban expressway merging areas involve multi-vehicle interactions and coupled lateral–longitudinal risk, which instantaneous longitudinal surrogate safety measures alone cannot capture. This study proposes a framework jointly capturing longitudinal car-f...

Differential Raman Spectroscopy Courier Face Sheet Detection Study Based on RCSC and 1DCNN‐Transformer

ABSTRACT To address the common issues of significant fluorescence interference, high data dimensionality, and low classification efficiency in detecting filler components in thermal paper courier face sheets, this study proposes an analytical method based on differential Raman sp...

Age-stratified analysis of the severity of injuries in electric tricycle accidents among the elderly, compared with other age groups

OBJECTIVE: Electric tricycles are widely used for short-distance passenger and freight transport in China, particularly in urban-fringe and rural areas. Their rapid growth has raised safety concerns because these vehicles provide limited occupant protection and frequently operate...
