Hard Hat Safety By California Contractors, Jonathan G. Hernandez
Construction Management
The hard hat is the quintessential item of PPE, and yet it often gets overlooked when ensuring safety standards are being met. We all expect our hard hat to protect us, but many never inspect it to ensure that it is properly fulfilling its purpose. This disregard to inspection and maintenance can lead to serious injury or death in the event of an accident. While organizations such as OSHA and the hard hat manufacturers themselves post information on this topic, it is unclear if this information is actually being received by the people involved in a construction project. This research …
Evaluation Of Bike Boxes And Protected Intersections With Bicycle Signal Treatments For Improving Safety And Multimodal Mobility At Urban Signalized Intersections, Odai Al Houz
Masters Theses
With the dramatic increase of non-motorized transportation users, more people are concerned about the non-motorized traffic safety. Unfortunately, bicyclist and pedestrian are prone to more severe injuries when involved in a crash. For bicycle crashes, failing to yield/disregarding traffic control device, and lack of non-motorized facilities were identified to be the main causes of bicycle crashes in urban intersections. This research investigated the effectiveness of two bicycle crash countermeasures with bicycle signal treatments at urban signalized intersections. The two countermeasures are the bike boxes and the protected intersections. The bicycle signal treatments are the leading bicycle interval and the exclusive …

An Embedded Sensory System For Worker Safety: Prototype Development And Evaluation, Chunhee Cho, Jee Woong Park
Civil and Environmental Engineering and Construction Faculty Research
At a construction site, workers mainly rely on two senses, which are sight and sound, in order to perceive their physical surroundings. However, they are often hindered by the nature of most construction sites, which are usually dynamic, loud, and complicated. To overcome these challenges, this research explored a method using an embedded sensory system that might offer construction workers an artificial sensing ability to better perceive their surroundings. This study identified three parameters (i.e., intensity, signal length, and delay between consecutive pulses) needed for tactile-based signals for the construction workers to communicate quickly. We developed a prototype system based …
