Current Issues and Complexities With Nighttime Work Zones: Safety, Mobility and Construction Issues
|OnDemand Webinar||$199||Add to Cart|
Current highway maintenance and reconstruction methods are increasingly moving to nighttime activities. The main reason this trend is increasing is because in many major metropolitan areas the only time when lane reductions can take place without resulting in delay is during the nighttime hours. However, there are many complications to nighttime work that can reduce driver and worker effectiveness, including: visibility of construction workers during nighttime hours, visibility of specialized equipment or construction related vehicles at the job site, controlling vehicle speed and guidance prior to and within the work zone, and providing glare-free illumination without distracting drivers. This OnDemand Webinar will help those responsible for designing and managing nighttime work zone construction and maintenance activities, to determine when these work zones are appropriate for use, and to understand the issues of work zone traffic control, lighting in the work zone, and motorist and worker safety. A review of work zone best practices will also be presented.
- You will be able to discuss the advantages of implementing a nighttime work zone.
- You will be able to review research highlights of nighttime work zones and recommended best practices.
- You will be able to describe references and specific recommended websites for practitioners.
- You will be able to identify the health, safety and welfare aspects of the issues with nighttime work zones.
