What are some devices used for temporary work zone
situations?And give me an explanation.
There are several devices used for temporary work zone situations, including:
1. Traffic cones: These are flexible, bright orange cones that are placed on
roads to redirect traffic or indicate where the work is taking place. They are
lightweight and easy to move as needed.
2. Barricades: These are typically larger and heavier than traffic cones, and
can be used to block off entire sections of the road. They are often made of
plastic or metal and can be painted with reflective stripes for increased
visibility, especially at night.
3. Channelizers: These are vertical, plastic devices that are used to guide
traffic safely through a work zone. They can be configured in various ways,
such as a zig-zag pattern or a tapering line, and they come in various heights,
depending on the situation.
4. Portable message signs: These are electronic devices that can be
programmed to display a message, such as "Lane Closed Ahead" or "Merge
Right." They are often mounted on a trailer and positioned near the work zone
to warn drivers of upcoming road conditions.
5. Arrow boards: These are another type of portable message sign that can
display arrows pointing in different directions. They are often used to indicate
a lane shift or detour, and can be particularly helpful at night when visibility is
poor.
All of these devices serve to increase safety and awareness in temporary
work zone situations by redirecting traffic and communicating important
information to drivers. They can help prevent accidents and keep road
workers safe
