Developing a Tracking-Based Dynamic Flash Yellow Arrow Strategy for Permissive Left-Turn Vehicles to Improve Pedestrian Safety at Intersections | Journal of Transportation Engineering, Part A: Systems | Vol 149, No 4
AbstractRecent data have shown that pedestrian fatalities have increased by 44% from 2010 to 2019. In 2019, 6,590 pedestrians died of traffic crashes, and 20% occurred at intersections, the highest…
A State-of-the-Practice Review of Three-Dimensional Laser Scanning Technology for Tunnel Distress Monitoring | Journal of Performance of Constructed Facilities | Vol 37, No 2
AbstractTunnel distress occurs often. Tunnel leakage, segment dislocation, and section deformation seriously affect tunnel construction safety and normal operation. Currently, mainly the traditional monitoring technology is used in tunnel distress…
Performance of the Chlorobenzene Destruction with Nonthermal Plasma: Effects of the Gas Conditions and the Gas Components | Journal of Environmental Engineering | Vol 149, No 4
AbstractNonthermal plasma (NTP) is a promising technology for the decomposition of chlorobenzene (CB), but many conditions will affect the performance of NTP. The effects of gas temperature, relative humidity, oxygen…
Exploring Time-Varying Characteristics in Drive-By Bridge Frequency Extraction with the Second-Order Synchrosqueezing Transform | Journal of Bridge Engineering | Vol 28, No 4
AbstractRecently, due to low cost and convenience, the concept of estimating the bridge’s first natural frequency through indirect measurements of a passing vehicle has gained increasing attention—known as drive-by bridge…
Flowability, Strength, and Water Absorption of Mortars Containing Fly Ash and WRA Having Varying Main Chain Lengths | Journal of Materials in Civil Engineering | Vol 35, No 4
AbstractWithin the scope of this study, the effect of the main chain length of polycarboxylate-based water-reducing admixture (WRA) on the fresh properties, compressive strength, and water absorption of mortar mixtures…
