There are many devices used to control traffic and promote driver and pedestrian safety.
There are many devices used every day to control traffic and promote driver safety. Many of these devices, such as the color and shape of stop signs, are so ingrained into driver consciousness that the word on the sign is almost unnecessary. These and other traffic control devices are helping to make our roadways safe.
Traffic Cones
Whether highway cones are knee high pieces of orange plastic, or heavy banded barrels filled with sand, the purpose of "road cones" remains the same. They direct vehicles away from dangerous areas and show the proper paths automobiles should take. Orange cones direct vehicles accident scenes, construction sites and other areas with restricted traffic flow.
Speed Bumps
Another traffic control safety device is the speed bump, made of concrete, steel or hard plastic. Speed bumps are small bumps in the road that cars have to drive over. If the vehicle speed is too high, the speed bump causes an annoying bounce, prompting the driver to slow down. Often used in residential and retail areas, these traffic control devices keep traffic slow and to make drivers pay careful attention.
Color-coding
Color-coding is another device. For instance, drivers know red means stop, yellow means caution, and orange means construction. Green lights mean go, blue signs mean information, and brown signs are for public parks. The meanings derived from colors help drivers adequately prepare for the hazards of the road and it keeps them aware of what lies ahead.
Traffic Signs
One of the most common methods of controlling traffic and maintaining road safety is to erect traffic signs. Stop signs, Do Not Enter signs, Caution signs and others are on most stretches of roadway. Traffic signs, whether permanent or temporary, give drivers warning as to what's ahead (speed limit signs and stop sign warnings are examples). Without signs to keep traffic organized, driving would be much more dangerous.
Roadway Paint
A major traffic control safety device is on the road itself. Painted lines and messages provide various instructions for drivers. Yellow paint, for instance, means it is a two-lane road, and white paint can mean it is a one-way road. A dashed line in the center of a highway means drivers may change lanes or pass, whereas a solid line means drivers cannot change lanes. Double yellow lines mean that traffic goes in opposite directions. When combined with other traffic control safety devices, the use of paint on the roadway is vital in promoting driver safety.
