MUTCD - Traffic Control Device Standards

In this video, we briefly explain the MUTCD and how it applies to several common traffic control devices. We touch on barriers, traffic cones, and delineating devices.

The MUTCD is the written regulation on traffic signs, lights, and other traffic control devices. It is a national standard however, most states supplement it with their own standards to meet specific needs. While the average person may think that the size, color, and shape of traffic control devices simply maximize visibility, most have a much more specific meaning.
First let's take a look at barricades. Barricades are designed to communicate road closings, restricted areas, and delineate changes in road lanes. They must be self-standing, have a minimum rail length of 24", and include at least one rail with alternating orange and white retro-reflective tape. The number of reflective rails on a barricade determines which type it is, 1, 2, or 3. Type 1 is used for conventional roads and urban streets. They require one 8" to 12" reflective rail face on each side. Type 2 is intended for freeways and higher-speed roadways where traffic is maintained through the work zone. These must include 2 retro-reflective rails on each side. Type 3 barricades are specifically used for complete road closures and may extend across the whole road. These barriers must have 3 reflective panels on each side. If you pay close attention the stripes on the panels will be pointing in a specific direction. This indicates the intended path around it in Type 1 and Type 2 situations.
Next, we'll take a look at traffic cones. The purpose of traffic cones is to channelize traffic, divide traffic lanes, and delineate short term maintenance for utility work. But not any old sports cone will work for this, it must be at least 18" tall and 28" tall on roadways where speeds exceed 45 mph. They must also be crash-worthy. Essentially they'll either collapse or bounce away if struck by a car, causing minimal damage to the vehicle.
The cone design must be predominately orange and have some kind of weighted base measure to keep them standing. At night cones must be equipped with lighting devices or retro-reflective bands. On those 28" cones the retro-reflective band must be 6 inches wide, and no more than 4" from the top, and another 4" band 2 inches below that.
Finally, we'll look at channelizing devices. These provide a smooth and gradual traffic flow through work areas and are usually used in conjunction with other traffic control devices such as signs. These are predominately orange and must be at least 42" tall for night-time use. They must also be crash-worthy. There are specific guidelines for delineator placement and spacing, depending on the type of road and the scope of work being performed.

Hi! I’m a CAD Operator and is currently working in California TCP and Encroachment for client standards. Do you have vacancy? I would like to apply.

you really show a person standing in the back of a pickup while the truck is in motion and they are picking up cones????
