Problem Statement
It is impossible to avoid an increase in traffic congestion in huge metropolitan areas that are expanding, such as those found in New York City and other major cities across the world. Congestion during rush hour is an inevitable consequence of how modern societies are organized (Lu et al.). It results from people's widespread desire to pursue specific goals, which invariably leads to overloading already-existing roads and transit systems daily. The vast majority of Americans in New York City who are on the move during peak commute times do so in their own cars. all forms of public transportation lack the comfort, speed, privacy, and convenience of privately owned vehicles. The global trend toward private automobile ownership directly results from rising per capital incomes, leading to an exodus from public transportation and other less convenient options. Because of many people drive their own cars on the road, despite the New York City government efforts to alleviate the problem, traffic congestion continues to get worse. This is something that is universally despised. It presents a substantial challenge for public policy, frequently leaves commuters feeling irritated and helpless. Although it's possible that governments may never be able to remove traffic congestion completely, there are a number of steps that states and municipalities can take to alleviate the problem. The primary mobility problem we face is that too many people want to move simultaneously every day. In order to keep the economy and educational institutions running smoothly, it is important that individuals go to work, school, and do errands at around the same time. It would be disastrous for our economy and way of life to abandon that fundamental requirement (Lu et al.). Every big city in the world faces the same issue. In my research plan, I will use the New York City as my target organization and New York State Department of Transport especially the engineering division as the agency to deal with the congestion during the rush hour.
Background
Agency Culture
In 1967, New York state department of transportation (NYSDOT) was formed. It is a department of New York state government responsible for the operation and development of mass transit systems, railroads, highways, ports, waterways and aviation facilities in the US state of New York. They also develop the transportation policy for the New York state. NYSDOT coordinate with the transportation and ensure all customers who live in New York have an efficient, safe, and balanced transportation system. The New York state department of transportation engineering division have the responsibility of addressing the challenge of congestion that has been reported in their desk. The New York state department of transportation engineering division is receiving the detailed report that argues that New York City is not doing well when it comes to the traffic flow especially during peak hours and this is wh.
Increasing the Road Capacity Not Always Improves the Travel Time: A Before an...IJERA Editor
This document analyzes the impact of reopening a formerly pedestrianized central square in Tirana, Albania to motor vehicle traffic. Data on travel times, waiting times, and passenger movement was collected for buses and passenger cars before and after the reopening. While travel times decreased in the central square, they increased in surrounding areas. Additionally, public transportation became overcrowded, pushing some passengers to use cars instead. In conclusion, reopening the square to cars did not truly solve congestion issues but rather shifted them to other parts of the transportation system. Encouraging alternative modes like biking or walking is presented as a more sustainable solution.
This document analyzes transportation modes between Boston, New York, and Washington D.C. Currently, road travel by car accounts for most trips but highways are congested. The document proposes a maglev high-speed rail system as an alternative. It compares the energy use, emissions, costs, and travel times of current modes like cars, trains, and planes to the proposed maglev system. An economic analysis is conducted to determine if the maglev system would be financially viable and beneficial in terms of sustainability and productivity for the Northeast Corridor region.

CALIBRATION OF VEHICLE EMISSIONS-SPEED RELATIONSHIPS FOR THE GREATER CAIRO ROADSIAEME Publication
The air pollution in Cairo is a matter of serious concern. The air pollution in greater Cairo is more than 10 to 100 times of acceptable world standards. There is a wide range of speed variation in Cairo. Consequentially, there is a wide range of emission rates. This research explains the relationship between vehicle speed and emissions for small cars using field tests. The representative car in this research is the Daewoo Lanus model 2000. This car is a representative for most small modern cars in Egypt. The mobile emission detector has been fixed on the car emission source. Tests have been implemented in two roads: Salah Salem road and Auto strad road. More than 1000 readings have been taken from the detector at various speeds. The speed varied between 0 and 85 km per hour and the relationships between speed and four types of emissions have been studied

IRJET- Evaluating Traffic Congestion and its Remedial MeasuresIRJET Journal
This document evaluates traffic congestion on NH-152, a 9 km road connecting Dera Bassi and Zirakpur in India. It has a high volume of mixed traffic due to factories, markets, hospitals and residences along the route. Video data was collected at 3 stations during peak hours to analyze traffic flow and identify congestion hotspots. The study aims to evaluate current congestion levels and propose remedial measures. Traffic congestion is a major problem in many cities due to inadequate road and transport infrastructure not keeping pace with rising population and vehicle ownership. It wastes time and fuel, harms the environment, and stresses commuters. Solutions are needed to contain congestion and maintain road capacity and traffic flow.
The document discusses proposals to reduce traffic congestion in New York City through various methods including congestion pricing. Some key points discussed are:
- Implementing congestion pricing in Manhattan south of 86th street, charging $8 for cars and $21 for trucks from 6am-6pm on weekdays.
- Lessons from London and Stockholm's congestion pricing programs show they can significantly reduce traffic and improve speeds when modest fees are charged.
- The current system of bridge and tunnel tolls in NYC is dysfunctional with different rates charged by different agencies. Congestion pricing could help streamline this system.
- A free market approach that varies pricing by time of day, day of week,
This PowerPoint presentation provides an overview of road network design and management. It discusses key concepts such as transportation and road network classification. It also examines characteristics of road networks such as oriented and unoriented types. Additionally, the presentation covers road network design elements, including route planning, design criteria, and design standards. It analyzes road network accessibility and control/operation, discussing evaluation indicators and traffic management measures. The goal is to establish high quality transportation services through road network planning and design.
1) Congestion pricing is part of a larger plan called PlaNYC 2030 that aims to improve New York City's environment, transportation system, and quality of life.
2) Congestion pricing would involve a daily fee of $8-$21 for vehicles entering or traveling within Manhattan south of 86th street between 6am-6pm to reduce traffic and raise funds for transit improvements.
3) Studies show congestion pricing reduced traffic by 16-25% in London and Stockholm, and was projected to reduce traffic in the NYC zone by 6-11% depending on location.

The participants researched applications of 3D printing and proposed using it to create a model of a stadium construction project. They first planned to design a stadium with each phase represented by height increases. However, they changed the proposal to a terrain model containing a stadium, solar-panel parking lot, condos, and surrounding fence, each with varying heights. They encountered obstacles in design and printing but overcame them. The project gave the participants hands-on experience with 3D modeling software and an understanding of 3D printing applications in various industries.

This document discusses analyzing the American Dream through a Marxist lens. It argues that applying Marxism can reveal hidden relationships between exploiters and exploited within capitalist societies. While the American Dream promises prosperity through hard work, some groups like immigrants face barriers that prevent them from achieving this. Examining the Dream with Marxism can help identify flaws and improve economic justice. However, a fully Marxist system could also create new exploiter/exploited dynamics. Overall, studying Marxism is useful to critically analyze economic systems like the American Dream, not to abandon capitalism altogether.

Abstract
As our current century flourishes with advancements in mechanical science, it is the art
of a civil engineer to facilitate these new technologies for the convenience and use of all men. In
the process, it is important to monitor state traffic and continue to upgrade all the reliable
resources that are necessary to achieve maximum revenue and safety for all citizens. These
resources are bridges, dams, roads, aqueducts, and canals, which provide humans with smooth
transitions from point A to point B. Further, as the proportion between new technology and the
innovation of metropolitan cities increases, population and drivers increase too. As a result,
traffic starts to accumulate within metropolitan cities, which provide delay and inconveniences
for all drivers. During construction maintenance in highways, traffic sometimes accumulates
when drivers intend to merge from one lane to another. Moreover, in between countries, such as
the United States and Mexico’s border, traffic continues to be an inconvenience for drivers. In
the past couple of decades, research has been conducted on traffic flow problems. With a further
analysis of traffic in intersection, highways, and the Otay Mesa border, civil engineers can
provide an understanding on how traffic is produce in order for all drivers to be more effective
and patience while driving, which simultaneously stimulates production in our nation.
Objectives: To expose the major factors of traffic in order to empower all drivers’ understanding
of traffic. Thus, providing solutions for drivers in order to proper accommodate to traffic and
alleviate the nation from the discomfort of traffic within big cities.

The Lighthill-Whitham Model
M.J. Lighthill, specialist in fluid dynamics, worked with G. B. Whitham in 1955 in order
to simulate macroscopic traffic flow (Jackson 4). This was known as the LW model. However,
their initial equation treats traffic only as a continuum (Jackson 4).
𝑝𝑡 + 𝑞 𝑥 = 0
Where we have these following representations:
p(x,t) is the traffic density (Vehicles per miles)
q(x,t) is the traffic flow (Vehicles per hour)
v is the mean traffic speed (miles per hour) & as a function of p.
A different model of this equation was founded by Payne in 1971 by adding a second differential
equation including a mean speed-density relationship and introducing other terms, such as
drivers’ anticipation, traffic flow relaxation, and changes in traffic volume (Jackson 5).
This equation looks like:
(𝑝𝑣) 𝑡 + (𝑝( 𝑣2
+ 𝑐0
2)) 𝑥 =
𝑝(𝑈( 𝑝) − 𝑣)
𝑇
and holds these representations:
v(x,t) is the space mean speed (km per hour),
T is the relaxation constant
𝑐0
2
is a positive constant
U(p) is the equilibrium speed-density relationship

Analysis 1 – Jamitons
With the Payne-Whitham model, vehicles traveling in a single-lane and uniformed road
can provide waves represent continuum traffic models. Assuming that all drivers behave under
the same laws and all unanticipated actions are eliminated, the traffic models can be viewed only
as a low traffic density model (Seibold). Clearly, not all roads are linear. Therefore, if one would
like to examine a road that curves, small perturbations would amplify and as a result, yielding to
models referred as phantom traffic jams. According to Seibold, these jams arise in the absence of
any obstacles. He states, “Vehicles are forced to brake when they run into such waves. In
analogy to other traveling waves, so called solitons, we call such traveling traffic waves
jamitons.” To further elaborate, in Pane-Whitham type of traffic models, instabilities grow into
traveling detonation waves (Seibold).
Below, there is a chart that illustrates a jamiton-induced fundamental with measurement data
*Tagged from Seibold.

From the data of Seibold’s studies, one can state that two major causes of traffic. The first
statement is that denser traffic travels slower. The second is that all drivers require a certain time
interval in order to react to incoming traffic. However, it is still crucial to remember that
Seibold’s studies did not introduce a scenario where a traffic light creates an increase in
congestion. Thus, it transitions us to discuss how traffic lights affect traffic.
Analysis 2 - Intersections
In a continuous flow intersection, traffic is allowed to flow from one intersection to
another, if and only if there are green lights present in a linear direction. When this occurs,
vehicles are allowed to advance on their travels. Co-terminus, the perpendicular linear road has a
red light and the cars waiting for the light to turn are unable to proceed.
The image above illustrates a continuous flow intersection. Suppose in one scenario, the first
signal light is red and the second signal light is green. This scenario creates a line of vehicles
6. 6Guinto
behind the first signal light that are unable to proceed, which creates a limit on the number of
cars that are allowed to advance pass the second signal light. Simultaneously, on the
perpendicular linear road, cars are also unable to proceed because they must stop in order to
allow the cars from the second light to pass. Clearly, we can see how this creates a problem.
Only when both the first and second signal lights are green is the traffic able to flow continuous.
According to the Great Britain’s Ministry of Transportation, the maximum seconds that a signal
light is allowed to be green is 70 seconds and the minimum is 35 seconds. When a light is green
at its maximum, it is referred as a Max-Out or Maximum Green. When a light is green at its
minimum, it is referred to as a Minimum Green. Moreover, when there is a Max-Out, the flow
rate of vehicles increases. However, the probability that a Max-Out is present is lower than that
of a Minimum Green. Therefore, a Minimum Green is one factor to a buildup of traffic within an
intersection.
*The chart below represents the probability of a Max-Out with respect to the Total Flow Rate

Analysis 3 – Peak Hours
During a certain period of day, the linkage between home and place of work create a jam
of cars that try vigorously to maneuver through each other, but instead create a big contribution
to traffic. This period of the day is called peak hours. Great Britain states, “Every morning, and
in the reverse direction every evening, great tidal flows of movement take place between the
residential areas and the places of work” (36). It needs to be understood that unless the hours of
work for all citizens is adjusted for different hours within all twenty-four hours of a day, peak
hours are inevitable. Altering the hours of work for all citizens, however, will create an even
more inconvenience than traffic itself. Therefore, when in traffic, drivers should remember that it
is never as bad as it seems. If drivers learn to anticipate the amount of time that is required to go
from point A to point B, (anticipating the amount of traffic, car maintenances, displacement, etc.)
than there could be less inconvenience within the time of travel.
*The chart below represents the volume of vehicles that are present at a given time interval due
to peak hours.

Analysis 4 – Speed Limits
Speed limits are another factor that affects traffic. For example, a high speed limit will
decrease the time of travel, but simultaneously puts the driver at risk of severe injury or death
due to the high impact if there is contact with any obstacles on the road. However, the limit of a
speed limit is determined by such factors: Environmental Capacity, State Minimum, and
Landscape.
*This chart illustrates the number of vehicles that would travel in 1 hour under the following
conditions:

Analysis 5 – Borders
The amount of drivers in America are increasing and as a result, creating traffic. The
ministries of transportation from Great Britain have published the “Traffic in Towns” textbook,
which contains studies on the attempts of past engineers that have tried to permanently remove
traffic, as well as provided theoretical approaches, based on statistics, to ease traffic. Great
Britain agrees when they state, “American experience shows that as vehicles increase in numbers
the usage per vehicle also tends to increase” (Great Britain 27). We can infer that if there were
fewer cars on the roads, there would also be less traffic. However, in order to reduce the number
of cars, we would first need to determine what factors increases the use of private vehicles. Great
Britain argues that “the growth in the number of private cars would seem to depend primarily
upon the growth of incomes, but it is also dependent upon the price of cars, insurance rates, [and]
taxation levels” (26). Unexpectedly, the amount of income that individuals allocate plays a part
in the amount of traffic that is formed at a given time because there is a correlation between
income and cost of maintaining a car. In the United States, a large majority of our population
comes from Latino communities, which yields a lot of tourism from the U.S. and Mexico, a
developing nation. In the Otay Mesa U.S. and Mexico’s border, there often seems to be traffic
for incoming vehicles headed to the U.S. However, if we study closely, we can determine that
the busiest hours of traffic are throughout the middle of the day. With this statistic, we can
provide drivers with appropriate hours of traveling from Mexico to the U.S.

*The chart below yields the following days, respectively: Tuesday, Wednesday, and Thursday.
Analaysis 6 – The Work Zone
On time of construction, the rate of traffic flow reduces due to it safety protocols, such as
providing a toll road for incoming vehicles to proceed to their destination. Co-terminus, this
provides a sweep distance from the work zone and allows space for engineers to work. One
possible solution to the decreased of traffic flow is to reduce the number of hours in the work
zone, which eliminates the need for a toll road. However, if the hours of work zone are reduce,
there needs to be an increase on the quality of work and materials used, which yields a higher
national budget cut. When this occurs, it is referred to as accelerated construction. Further, when
the time of construction is high, but the budget is at a constant, it is referred to as traditional
construction. From the chart below, we can argue that since 2009, accelerated construction has
been increasing. Therefore, we can conclude that traffic will reduce due to the accelerated
construction, but at the cost of our nation’s budget. In addition, it is important for drivers to
decide if it is worth tolerating the inconvenience of traffic for a few minutes and in exchange
keep our national budget high or to eliminate as much traffic as possible at any cost.

Conclusion
Despite our nation’s current status of advanced technology that would imply faster
transitions for road traveling, it is essential that drivers accept the presence of traffic as a
sacrifice for urban development and safety. Although the various factors that affect traffic have
been analyzed and targeted for accommodation – such as, state population, peak hours,
geographical landscaping, and road structures – to yield efficient driving, drivers should keep in
mind that traffic is almost inevitable. Further, it is crucial to remember that other factors, non-
traffic related, can create more discomfort than the frustration of traffic. A simple example is
when the quality of life of a nation is infiltrated by changing the hours of work of all citizens in
order to eliminate peak hours. Moreover, the best way to execute a safe driving experience for all
drivers and non-drivers is to be prepared to deal with traffic as soon as they leave their homes.
Otherwise, traffic will continue to create an unwanted discomfort and make life more difficult.
Although for some drivers, patience is difficult to gain, with this analysis of traffic, drivers
should be more informed about what affects traffic. Further, for all civil engineers, the Payne-
Whitham model should be a starting point towards analyzing traffic. With the Payne-Whitham
model, many simulations can be articulated and use to anticipate traffic. However, the Payne-
Whitham model is limited due to its perfect error. Yet, one should always remember that traffic
can never be anticipated precisely. A benefit that all drivers should have gained through this
analysis is a deeper understanding of what affects traffic to accommodate for it and as a result,
create a safer driving experience.
