Traffic congestion occurs when traffic demand exceeds road capacity, resulting in slower speeds and longer trip times. It is a major source of frustration for motorists and reduces travel speeds. The main causes of congestion are high traffic volumes, inadequate infrastructure, and irrational urban planning. Congestion leads to economic losses from wasted time and increased fuel costs, as well as environmental issues from higher emissions. Potential solutions involve improving road infrastructure, implementing smart urban planning, managing supply and demand through techniques like road pricing, and using traffic management strategies.

2.  Traffic
congestion is a condition on road networks that
occurs as use increases, and is characterized by slower
speeds, longer trip times.
 Congestion
is a situation in which demand for road
space exceeds supply.
 When
traffic demand is great enough that the
interaction between vehicles slows the speed of the
traffic stream, this results in some congestion.

3. It is understandable that many people consider
congestion a significant problem.
 Typical urban residents spend more than ten hours a
week driving of which 10-30% (one to three hours)
occurs in congested conditions.
 Traffic congestion reduces travel speeds, creates
uncertainly and requires more driver effort. It is a
major source of frustration for busy, productive people.
Motorists often feel that reducing congestion would
make their lives more efficient and satisfied.
 As a result, conventional planning considers congestion
a major problem and congestion reduction a dominant
planning objective.

4. It is said that the high volume of vehicles, the
inadequate infrastructure and the irrational distribution
of the development are main reasons for increasing
traffic congestion.
 The major cause leading to traffic congestion is the
high number of vehicle which was caused by the
population and the development of economy.
 If you live in an urban area, traffic congestion can be a
major daily headache. It's bad enough that there isn't
enough road capacity for the increasing numbers of
vehicles travelling on them, and rude and aggressive
drivers make a bad situation even worse.

5.  Traffic
Problem in Pakistan is getting worse with
every coming day specially in big cities like Karachi ,
Lahore, Rawalpindi , Islamabad, Quetta, Peshawar
and Hyderabad.
 Government is doing very little efforts to avoid
traffic jams and other traffic problems in Pakistan.
Following the major causes of traffic problems and
their solutions.

6.  Small
roads for the number of cars and motor
cycles.
 Rapid growth of the population. As a result of this,
the number of cars is increasing annually.
 There are more women drivers and younger drivers
today than in the past.
 The increase in the number of trucks and
commercial vehicles also causes traffic congestion,
These vehicles move very slowly, sometimes
stopping to unload goods, and blocking traffic.
 Broken roads – as people don’t like to move from
the broken part so traffic increases on rest of the
roads.

7.  Old
cars and trucks. Government don’t have a clear
policy about old cars and trucks. Even 50 years old cars
are still running on roads.
 One of the most important is parking problems. People
find it difficult to park their cars especially in the city
center.
 More cars due to bank financing . Now everyone can
afford a car so more cars are there on the road.
 Lack of traffic sense among the people. People don't
have traffic sense. Traffic police and media should play
their role in creating traffic sense amongst the people.
 Corruption among the traffic police in Pakistan. People
know that if they will break the law they will easily be
released by giving few rupees to the police man.

10. 
When we request a police officer, an ambulance or a
fire truck and the emergency vehicle is unable to
respond in an appropriate amount of time because of
traffic congestion it can be a danger to you and your
property.

11. 
The first thing many people think of when it comes to
congested roadways is the delay. During the morning
there is additional stress because delays caused by
traffic can make people late for work. And at the end of
the day, the afternoon rush hour is again a frustrating
time because the workday is done and people want to
get home to relax, and traffic is preventing it.

12. • One beneficial effect of traffic congestion is its ability to
encourage drivers to consider other transportation options. In
cities with frequent traffic congestion, individuals often choose a
subway, light rail or bus service. These options reduce traffic on
the roads, have less of an environmental impact and reduce the
stress associated with driving in heavy traffic.

13. 
Uncertainty and unreliability in every services

Wasting time of motorists and passengers
As a non-productive activity for most people,
congestion reduces regional economic health.

Wear and tear on vehicles as a result of idling in
traffic and frequent acceleration and braking,
leading to more frequent repairs and
replacements.

14. 
Road rage
Aggressive or angry behavior by a driver of an
automobile or other motor vehicle. Such behavior
might include rude gestures, verbal insults, deliberately
driving in an unsafe or threatening manner, or making
threats. Road rage can lead to altercations, assaults, and
collisions which result in injuries and even deaths.

18. 
Pollution
One of the most harmful effects of traffic congestion is its
impact on the environment. Despite the growing number
of hybrid vehicles on the road, cars stopped in traffic still
produce a large volume of harmful carbon emissions.
Besides contributing to global warming, these emissions
can cause more short-term and localized problems, such
as smog and increased respiratory problems in a
community due to poor air quality.

19. 
The stopping and starting in traffic jams burns fuel at a
higher rate than the smooth rate of travel on the open
highway. This increase in fuel consumption costs
commuters additional money for fuel and it also
contributes to the amount of emissions released by the
vehicles. These emissions create air pollution and are
related to global warming.

City planning and urban design practices can have a huge impact
on levels of future traffic congestion, though they are of limited
relevance for short-term change.
Grid plans including fused grid road network geometry, rather than
tree-like network topology which reduce local traffic, but increase
total distances driven and discourage walking by reducing
connectivity.
Transit-oriented development are residential and commercial areas
designed to maximize access to public transport by providing a
transit station or stop (train station ,metro station , tram stop,
or bus stop).

Congestion can be reduced by either increasing
road capacity (supply), or by reducing traffic
(demand).
Increased supply can include:
Adding more capacity at bottlenecks (such as by
adding more lanes at the expense of hard
shoulder or safety zones, or by removing local
obstacles like bridge supports and widening
tunnels)
Adding more capacity over the whole of a route
(generally by adding more lanes)

25. Reduction of demand can include: Parking restriction :- making motor vehicle use less

attractive by increasing the monetary and non-monetary costs of
parking. introducing greater competition for limited city or road
space.

Road pricing:-

Telecommuting:- encouraged through legislation and
charging money for access onto a
road/specific area at certain times, congestion levels or for certain
road users
subsidies.
