FUNDAMENTALS OF TRAFFIC CONTROL
Concept
Traffic Control. Generally, it refers to procedures, devices, and communication
systems that help vehicles and vessels safety share the same roads, rails,
waterways, or air space. Traffic control establishes,
A. Traffic Control as Applied to Land Transportation. A system of traffic
engineering, employing prescribe traffic rule and regulations and devices such as
signals, and markings, to relieve vehicular congestion and air pollution, and to
promote safety and pedestrian mobility, usually in heavily populated urban areas.
In smaller towns, with lighter traffic, similar but simpler control devices and
engineering techniques are used.
B. Control Techniques. The primary emphasis of traffic control is on the
safe and efficient flow of cars, buses, vans, and lorries over urban streets and
highways. The means of promoting this can vary from simple improvement of
local streets by installing traffic signs and road markings to constructing
comprehensive motorway control system. These systems are:
1. Access-road meter to monitor and control motorway;
2. Closed-circuit television surveillance to detect quickly any
deterioration in traffic flow; and
3. Emergency services in case of accident and injury.
C. Other traffic-control techniques include:
1. The use of one-way streets,
2. Enforcement of traffic flow regulations,
3. Channelization (building traffic islands, turning lanes and so on),
and
4. The use of traffic signals.

D. Highway Traffic control. Motorists depend on traffic control devices to
avoid collisions and travel safely to their destinations. Traffic control devices for
highway travel include signs, signal lights, pavement markings, and a variety of
devices placed on, over near, or even under, the roadway.
1. Traffic Sign. Traffic signs are the most extensively used form of
traffic control in the United States. More than 55 million traffic signs line
the nation’s roadside. They provide information about speed limits and
road conditions. They direct traffic along certain routes and to specific
destinations. By using sign, traffic control planners tell drivers what to do,
what to watch for, and where to drive.
2. Pavement Markings. Pavement markings separate opposing
streams of traffic and direct vehicles into proper positions on the roadway.
For example, pavement markings delineate turn lanes at intersections and
establish no-passing zones. White and yellow paint is customarily used for
pavement markings. Reflective devices are more visible at night and are use
in some locations to mark lanes and other significant places on the road.
Traffic signs and road markings follows a uniform practice
throughout the world and are designed to convey information with the a
minimum of words to avoid confusing drivers unfamiliar with the area and
the language. Uniform pictorial signs and markings have been adopted
throughout Europe and United States. They include uniform sign formats
and sizes, and uniform codes regulating traffic flow.
3. Traffic-Signal. Traffic signals are installed to permit safe
movement of vehicles and pedestrians at busy intersections. The signal
light is probably the most easily recognized traffic control device. At a busy
intersection in a large city, a traffic signal may control the movements of
than 100,000 vehicles per day. More than 60 percent of all miles driven
each year are on roadways controlled by traffic signals.
Traffic signals direct streams of vehicles and pedestrian when to go,
stop, or proceed with caution. The signals increase the traffic-handling
capacity of most intersections. They can work independently on timers, or
connect to computer-controlled system that operates over several
intersections.

4. Priority Control. In one of the oldest method of traffic control,
one from of transportation is given priority by restricting or banning other
forms of transportation. In the 1st century BC, Roman Emperor Julius Caesar
banned wheel Traffic from Rome during daytime, which allowed
pedestrians and horse riders to move freely around the city. Some modern
cities ban or restrict truck travel through certain neighborhoods.
Bus-lanes and high-occupancy vehicles (HOV) lanes exist in many
urban areas. Only specified types of vehicles, primarily those carrying
several occupants, can use these lanes by giving priority to high-occupancy
vehicle, transportation planners encourage carpooling and reduce
congestion.
5. Restraints. As an alternative to banning traffic, traffic control
planners use devices to discourage heavy use of a route. Island built in the
centers of intersections force drivers to proceed slowly. Speed bumps
discourage high-speed commuting through residential neighborhoods.
Concrete median strips prevent vehicles from making turns except at
intersections.
TRAFFIC SIGNS
Concept:
Traffic signs, like traffic signal lights and road markings are used to convey
quickly and accurately the wide range of information needed by road users,
particularly vehicle drivers, and to promote a safe and efficient use of the road
system.
Traffic Signs refer to any device mounted on portable support whereby a
message is conveyed by means of words or symbols officially installed for the
purposes of regulating, warning, or guiding traffic. Traffic signs are installed to
serve the following functions: 1) to control traffic, 2) to safeguard the flow of
traffic, 3) to expedite traffic, and 4) to guide traffic and motorists.
Standardization of traffic sign shall conform to the standards set forth in
the erection and display of standard road signs and markers as prescribed by the
