Signs, markers, and signal devices are used to control traffic as well as inform and guide citizens. Typically known as traffic control devices, they help vehicle drivers, bicyclists, and pedestrians. Devices are typically placed adjacent to or near highways, roads, and other areas where traffic needs to be controlled. Drivers must obey the instructions provided by official traffic information devices unless otherwise directed by a police officer.
New drivers often ask, "why use traffic control devices?" The devices serve critical needs in communities. For example, California traffic signs and markers prevent accidents, maintain orderly traffic, minimize gridlock, and reduce the number of severe accidents.
Better Organized Traffic Movement
It is essential to have traffic management devices that direct traffic, especially at intersections. Without the devices, roadways would become disorganized and dangerous. Markers and signs that direct vehicles' movements create a safer, more efficient environment.
Greater Driver, Passenger, and Pedestrian Safety
Whether traffic is on public roadways, private property, or in parking facilities, the top priority is keeping people safe. Traffic management devices protect those in and near traffic. Without these controls, accidents would happen far more often, and roads would be hazardous.
Even parking lots and garages would be unsafe without directional signs or markings. That's why parking lot barricades are often used to prevent drivers from entering unsafe areas, traveling in the wrong direction, or parking in reserved sections. Markings and signs assist pedestrians and drivers by noting the flow of traffic as well as exit and entry areas.
Fewer Severe Accidents
The most serious accidents occur in or near intersections, but there would be far more incidents without traffic indicators. Signs and signals often regulate the traffic flow, which prevents drivers from going the wrong way. Traffic management devices such as lights help by assigning drivers the right of way.
Prevent Traffic Gridlock
When traffic falls into disorder, gridlock can result no matter where vehicles are. Traffic systems are frequently used at intersections, toll booths, and automatic gates to maintain order.
Without a system that directs drivers, gridlock can quickly occur, increasing the chance of accidents. Gridlock also presents a threat because it can distract drivers and decrease their ability to focus on driving.
Maintain Order During Rush Hour
Most communities or cities now experience some level of rush hour traffic, usually in the mornings and evenings when citizens are traveling to and from work. There are more vehicles on the roads during these periods, which increases the likelihood of accidents.
Traffic management devices are essential to control traffic during rush hour. Devices help drivers, passengers, and pedestrians stay safe in heavy traffic.
Cities and towns rely on traffic management devices to keep traffic orderly, which helps prevent gridlock and minimizes the severity of accidents. The devices help keep traffic organized and running smoothly, even during rush hour.
