4. TRAFFIC SIGNS & CONTROL SYSTEMS

Traffic Signs

The traffic signs convey many different kinds of message to the driver, they can state       laws, warn of hazards, or provide instructions and guidance to the operator. As one travels down the road ways, the shapes or colour of the sign can be recognised or the message read. For this reason, traffic signs have been standardized by shapes and colours. Each shapes and colours has a specific meaning.

The general principle of traffic signs is to make a massage known quickly, (70 mph) accurately with a minimum reading skills required. It can be defined as the devices placed along, besides, or above a highway, or roadway, pathway, or other route to guide, warn, and regulates the pedestrians, equestrians, and other travellers. They serves 3 different purposes.

1. Regulate traffic, movements, or parking.

2. To warn of potential dangers or changes in road conditions.

3. To provide information and guidance.

Road Signs, markings, traffic signals and other traffic devices are there to guide the road users and hence are the languages of the road. Every road user whether a pedestrian, two-wheeler rider, driver of four-wheeled vehicle should have knowledge regarding these traffic controlling devices and should be aware of what they signify. Traffic Signs are there to regulate traffic, warn about hazards and to guide the road user.

Control System

The common traffic control systems are discussed below

1. Light Control System

* Traffic Light

There are mainly three types of traffic lights colouring systems are used; they are namely, RED, YELLOW, GREEN. RED:



 Come to complete STOP at stop line orbefore    cross    walking    or intersection.

• After stopping, you may turn right on red at most intersection if the way is clear.
• Some   intersection   displays   “NO TURN ON RED”; which you must obey.

YELLOW

• STOP if u can do so safely.
• The light will soon be RED.

GREEN

• Go, but only if intersection is clear.
• If turning left wait for gap in coming traffic to complete turn. Same as to the lighting system the lighted arrows are used in some cases.

RED arrows:

• Come to complete STOP at stop line or before cross walking or intersection.
• After stopping, you may turn right on red at most intersection if the way is clear.
• Some intersection displays “NO TURN ON RED”; which you must obey.

YELLOW arrow:

• STOP if u can do so safely.
• The light will soon be RED.
• Means the same as yellow light, but applies only to movement in the direction of arrow.

GREEN arrow:

• A green arrow, pointing right or left, means you may make a turn in the proper lane for the turn after yielding pedestrians, even if a red light is showing at the same time.

Steady Green Arrow Signal

• Proceed with caution in the direction indicated by the arrows.Remember  that  you  must  yield  to  all pedestrians and vehicles already in the intersection.

Flashing Red Signal

• You must come to a complete stop, yield to all other traffic and to pedestrians. Proceed only when the way is clear.

Flashing Amber Signal.

• You should slow down and proceed with caution.

* Lane Signal

The lane signals are used;

• When the direction of the flow of traffic changes.
• To show that a tool booth is open or closed.
• To show which lanes are opened or closed.
• You must never drive in a lane signal under red ‘X’
• A yellow X mark means that your lane signal is going to change to red. Prepare to leave the lane safely.
• You must drive in lanes beneath a green arrow you must also obey all other signs and signals.

* Indicator Lamps

• Indicator lamps are to be used for the direction in which the vehicle to move.
• These are in flashing amber colour and with an effective sound (in modern vehicles).
• A vehicle have a left, right and hazard indicators.

* Reflectors

Road reflectors are used to control traffic and encourage safe driving conditions. Road reflectors are made from ceramic or plastic. Road reflectors are also known as traffic delineators, raised pavement markers, road markers, cat’s eyes, road studs, and Botts’ dots. Some types of road reflectors have a reflective lens that reflects the light from vehicle headlights. Road reflectors are used for a variety of purposeds, and are especially important for making traffic lanes visible to drivers at night. The usage de
