Optimized Design of Safety Facilities for Maintenance Sections of Eight-Lane Expressways
With the increasing service age of early expressways, routine maintenance and major repairs have become key priorities in current expressway operations. However, maintenance activities often occupy … [Read more...] about Optimized Design of Safety Facilities for Maintenance Sections of Eight-Lane Expressways
Leveraging Large Language Models and Deep Learning for Construction Work Zone Intrusion Risk Assessment
Construction work zones are essential for roadway maintenance. In most cases, the traffic flow should not be interrupted, which requires work zones to be set up alongside the ongoing traffic, … [Read more...] about Leveraging Large Language Models and Deep Learning for Construction Work Zone Intrusion Risk Assessment
Identifying and Categorizing Safety Risk Factors Causing Vehicle Intrusions in Work Zones
Work zones pose significant safety risks to both drivers and workers. Identifying and categorizing those risk factors impacting work zone safety is crucial for implementing effective countermeasures. … [Read more...] about Identifying and Categorizing Safety Risk Factors Causing Vehicle Intrusions in Work Zones
Digital Twins for Detecting Worker Geofence Violations in Road Construction Work Zones
Work zone intrusions have been recognized as a safety-critical incident in road construction, often leading to injuries and fatalities. The causes of intrusions are twofold: (i) driver recklessness or … [Read more...] about Digital Twins for Detecting Worker Geofence Violations in Road Construction Work Zones
A Multibranch Risk Assessment Model for Multi-Lane Highway Work Zones Based on Risk Fields and Graph Attention Network
This paper addresses the challenge of real-time safety assessment in multi-lane highway work zones by introducing two key innovations. First, we formulate a Comprehensive Collision Risk Index (CCRI) … [Read more...] about A Multibranch Risk Assessment Model for Multi-Lane Highway Work Zones Based on Risk Fields and Graph Attention Network
