Traffic Congestion is a condition on transport networks that occurs as use increases, and is characterised by slower speeds, longer trip times, and increased vehicular queuing. Based on the 2015 Global Satisfaction conducted by Waze, Metro Manila has the “worst traffic on Earth”. Based on the 2015 Census of population by the Philippine Statistic Authority, Metro Manila was listed as being the most dense city in the world based on population density.

Emerson Carlos, MMDA assistant general manager for operation, mentioned that in 2015, the total motor vehicles registered in Metro Manila have already peaked at 2.5 million. This increase of vehicles on the road is one of the major contributing factor that leads to the worsening traffic congestion in Metro Manila.



Infrastructure Problems
One of the primary causes on traffic within Metro Manila is the current transportation infrastructure. Overall, there is lack of quality infrastructure thus a insufficient modes of mobility. While the Duterte administration have promised that the next years will be "“golden age of infrastructure”, with a record $168 billion to be spent on 5,000 projects across the nation” , we have yet to see this come to fruition.

Road Network

The road network of Metro Manila consists of radial (R-1 to R-10) and circumferential (C-1 to C-5) roads. These are the principal arteries within the city, however given the propensity of vehicles within the metropolis the roads have become inadequate. "Metro Manila only has 1 km of road per 424 vehicles."

Furthermore, the roads are of poor quality and do not receive maintenance. For example, in the scope of the entire country, "Of the 31,400 km of national roads in the system, only about 45% (14,200 km) were assessed as being in good or fair condition in November 2011.” The poor quality of roads have made road-transportation inefficient. Furthermore, this has contributed to the increase of road accidents, which therefore affects both traffic congestion and public health.

The Railway System

The current railways carry around 1.3 million passengers per day and spans 79km in 4 different lines. In 1998, plans for a railway expansion were implemented however only 5 km of the planned 73 km was actually built. As such, there exists a lack of an adequate non-road-based public transportation system. This is made evident in the problem of overcrowding during peak hours.

Road-based Public Transport

In Metro Manila, there exists a variety of road-based public transport, such as tricycles, taxis, buses, and jeepneys which are all privately owned. While there is such a prevalence of these modes of transportation, these "account for more than 50% of daily commuting trips, incur no subsidy, and with low productivity.” Meanwhile, "car travel accounts for 30% of person-km, but constitutes 72% of the road traffic in terms of PCU-km.” The high amount of vehicles on the road, which could be attributed to the high population, is one of the contributors to traffic congestion.

Urban Planning Problems
The layout of Metro Manila lacks holistic and intrinsic planning from the ground up. The poor design did not account for the density of the city or the eventual propensity of vehicles. A classic example is the fact that the city hosts more vehicles than the roads could afford. Furthermore, laws and policies that are meant to mitigate such poor design is not enforced properly.

Urban Area Expansion

The urban area of Metro Manila experiences a high growth rate in population. Within the period of 2000-2001, the city experienced a rate of 1.8%. This growth rate is a result of spillover of people from nearby towns, cities, and provinces. As the main hub of the Philippines, the influx of people is foreseeable yet the city has not taken such into account. Thus, the urban planning of the city is not adequate vis a vis the high population density. Statistics show that the city must "accommodate an additional of about two million and six million by 2030.” Thus, if such trend continues 224 persons per hectare is estimated. This high population thus calls for an appropriate transportation system to allow for mobility within the city.

Traffic Congestion



"Today, traffic demand is at 12.8 million trips in Metro Manila… Most of these trips are done using the public transport owing to its 69% share of total trips. The lesser share of the trips is done by private mode and yet it is this mode that takes up 78% of road space.” At the current state, the traffic volume within the metropolis already exceeds the capacities of existing roads. The urban planning failed to bring into fruition a public transport system that could function in the dense, compact city of Metro Manila.

Economic Theories
The Roadmap for Transport Infrastructure for Metro Manila and its Surrounding Areas (Region III & Region IV-A) study by the Japan International Cooperation Agency (JICA) in response to the National Economic Development (NEDA) request for assistance in creating a guide for transport development in Metro Manila, the two regions of Central Luzon and CALABARZON. The guide is help NEDA deliberate on the contents of a short-term (2014 - 2016) and a medium term (2017 - 2022) transport investment program (TRIP).

For the short-term transport investment program (TRIP), it takes the goals of the Philippine Development Plan for 2011 to 2016 and makes it into projects in the transport sector. It has invested as much as 5% of the GDP in infrastructure as one of the five key strategies to achieving the TRIP. A huge difference from the previous investing rate, as low as 2% of the GDP.

Same study has also found that during their research period, the Metro Manila traffic was costing the city and the people Php 2.4 billion per day in the year 2012. And, if no measures are undertaken, this transport cost can rise up to Php 6.0 billion per day in 2030. This is will be worst case scenario in the increase of transport costs Metro Manila and the areas of Bulacan, Rizal, Laguna, and Cavite if there will be no improvements done on the transport infrastructure of these areas and the Philippines overall.

High Population/Vehicle Density
In Busina: Current State, Alternatives and Emerging Filipino Values on Metro Manila Traffic, Metro Manila is classified as a global power city. This is because of majority of the industries present in the Philippines have located their offices in the National Capital Region (NCR). The city is also where all the foreign consulates and embassies are situated. This makes NCR the home of finance and commerce, hence the allure of in-migration from Filipinos from the provinces. Although this is not the main cause of road traffic in the city, the influx of people adds to it.



Yves Boquet, in his paper Battling Congestion in Manila: The EDSA Problem, quotes Robert Cervero in saying globalization, outsourcing and relocating much of the manufacturing activities are just some of the other causes that add to the high population in Metro Manila. These activities are mainly responsible for the influx that was previously mentioned. These activities are creating the job that appeal to people in the province to make the move. More people in the city plus the rise in the purchasing power of most people in developing Asian countries, added to the vehicle density of in Metro Manila. An example of this purchasing power, according to Euromonitor’s Consumer Lifestyles in the Philippines (2015), is that young professionals in the Metro tend to buy smaller cars such as Toyota Wigo, Mitsubishi Mirage and Honda Jazz. This is due to the affordability of said cars but also the added bonus of not using public transport.

Referring back to the study of the EDSA Problem, it dubs the avenue as the main passageway of the Greater Manila area, the city accounts for 35.7% of the Philippines’ economic output, 18% of its population and 28% of its motor vehicles. All of which are accommodated on barely 0.2% of the country’s land area.

Public Transportation System


The main modes of public transport in the Philippines are jeepneys, buses, taxis, trains and tricycles, all of which are readily available in Metro Manila. The introduction of transportation apps Grab and Uber came in 2013 and 2014, respectively, and further widening the options of public transport. The Philippine traffic is considered as the world’s 9th worst in 2015 by Numbeo despite this range of public transport options. Although there is a wide array of choices, the public still spend an average of 45.5 minutes before reaching their workspace. This is why most Filipinos still find travelling inconvenient via public transport due to the high vehicle density and the unavoidable traffic congestion according to Euromonitor’s Consumer Lifestyles in the Philippines (2015).

Road Accidents


According to Metro Manila Accident Reporting and Analysis System (MMARAS) data from 2008 to 2011 and a study of the severity of road crashes in Metro Manila, accidents that involved heavy and multiple vehicles, and an elderly pedestrian (60 years old and above), as well as those that occurred during the evening (7 pm to midnight) and late at night (1 am to 5 am) had significantly higher odds of resulting in a fatal outcome. But when the crash involves a female pedestrian and when the road surface is wet the odds of a fatal outcome are lower. The study found that most accidents involving pedestrians happen on high-speed, high-traffic-volume, multilane roadways, that are surrounded by land uses that generate a mix of heavy vehicular and pedestrian traffic. It was also found that fatal crashes involving pedestrian happen close to different types of transit stations.

Social Effects
The congestion of vehicles on the road is not entirely unhealthy for the society. In a more specific viewpoint, the congestion between vehicles within a particular region, allows the circulation of other vehicles. Congestion occurs inevitably in highly urbanized sectors where the ratio between the population of people and the given area is not proportional and when the demand is high. In some cases, it is even desirable up to a certain point since getting rid of it imposes higher costs than allowing it to persist. The main social effects that occur due to the congestion of vehicles are namely: wasting of time (non-productivity; opportunity cost), delays, frustrated drivers/motorists/passengers, encouraging road rage.

Wasting of time

The time spent in traffic can be considered as unproductive or generally, a waste of time. The concept of opportunity cost comes into play especially for people who have other places to be instead of being stuck in traffic.

Delays

The traffic congestion in highly urbanized cities can be a huge detriment in terms of the delivery of goods from once place to another, leading to the loss of trust between parties who rely heavily on these daily deliveries for the benefit of their own businesses. Essentially, it may lead to situations such as: late arrival for work, important meetings, and school, which may result in lost business, disciplinary action or other personal losses. Delays may also come in the form of congestion may interfere with the flow of traffic when it comes to emergency cases (ambulance, police cars, etc.)

Frustrated Drivers



The most commonly known effect of heavy traffic congestion would be in the form of “Road Rage”. Road Rage is the aggressive behavior of an automobile driver which includes rude gestures, verbal insults and deliberate reckless driving that may endanger the lives of both the drivers and the people surrounding them.

Economic Effects
Traffic congestion, in some cities, does more good than bad to a certain extent. And in other cities, it does more bad than good. Congestion on the road, from an Economic viewpoint suggests that higher levels of congestion are related to faster economic growth. However, above a certain limit, congestion starts to become a detriment to economic growth and the overall welfare of society, rather than an asset. This is due to the cost of the alleviation of congestion in some cities would be higher than the cost of congestion itself.

Delays

The traffic congestion in highly urbanized cities can be a huge detriment in terms of the delivery of goods from once place to another, leading to the loss of trust between parties who rely heavily on these daily deliveries for the benefit of their own businesses. In any case, delivery of raw materials to be turned into finished products or inventory is a time-sensitive task, and traffic congestion does not contribute positively to this sector.

Damaged Vehicles

The depreciation on vehicles as a result of staying still in traffic and the often use of acceleration and brakes, eventually resulting into more repairs or expenses in general.

Loss of Revenue for Public Transport

Public transport, trucks and other services are also affected by the traffic in Metro Manila. Instead of being able to do three or four round trips, they usually end up doing less; which means a significant loss in revenues, and ultimately leading to a failing business. Public transportation also suffers in that the available schedules become less frequent and the time spent waiting is longer.

Environmental Effects
Aside from social and economic effects, traffic congestion also has massive effects on the environment, specifically its contribution to air pollution. According to the World Health Organization (WHO), air pollution is defined as the contamination of the indoor or outdoor environment by chemical, physical, or biological means. Air pollution is an “invisible danger” that people must not ignore. Despite the fact that it cannot be seen, air pollution has affected the lives of a number of Filipinos. The WHO said that air pollution is killing millions worldwide, including those in developing countries like the Philippines. Furthermore, the Metropolitan Manila Development Authority (MMDA) noted that dirty air threatens the lives of 12 million residents.



The effects of pollutants found in vehicle exhaust include the following:
 * High levels of nitrogen oxide are toxic to humans
 * Sulfur dioxide is the primary cause of acid rain
 * Carbon dioxide contributes to climate change by insulating more heat from the sun
 * Ozone can impair lung function

According to the National Emissions Inventory, last 2012, 71% of the air pollution in the Philippines comes from vehicles on the road. Furthermore, the situation is much worse in the National Capital Region (NCR), wherein 85% of the air pollution comes from vehicles. Also, based on data gathered from the Department of Environment and Natural Resources, Metro Manila’s air quality situation has worsened in terms of total suspended particulates. There was a rise from 106 µg/Ncm in July to December 2014 to 130 µg/Ncm in January to April 2015, which are both above the maximum safe level of 90 µg/Ncm.

The more cars there are on the road, the more pollution is emitted into the air. This is because motor vehicles are one of the main sources of pollution in the world. On the other hand, there is an inverse relationship between the moving speed of traffic and air pollution. The slower the traffic moves, the more pollution is emitted into the air. This is due to the fact that cars burn the most fuel when accelerating to get up to speed. More gas is used up whenever there is an on and off pressing on the gas and break pedals during traffic jams.

Thus air pollution continues to be a serious threat in the Philippines. There have been efforts to lessen the number of vehicles on the road and the production of fuel-efficient green cars with reduced emissions, but air pollution remains to be a problem. The Guardian said that “despite all the promises of green growth and reduced emissions, traditional car sales are accelerating, while efforts to shift towards ‘greener’ hybrid and electric vehicles are stuck in neutral, particularly in the place where it matters most.”

Department of Transportation
In August of 2016, The Department of Transportation (DOTr), in charge of the country’s transportation systems, has moved towards a more integrated approach to managing traffic on Metro Manila’s roads. To do so, the department divided the metropolis into 10 traffic sectors so as to be able to share assets among other government agencies involved in traffic management such as the Metropolitan Manila Development Authority (MMDA), the highway Patrol Group of the Philippine National Police (HPG-PNP), the Land Transportation Office (LTO) and the Land Transportation Franchising Regulatory Board (LTFRB). According to the DOTr, by combining forces and coming up with a single chain of command, the agencies will be able to collaborate for better traffic monitoring, uniform implementation of penalties and joint training for traffic personnel.

Metro Manila Development Authority (MMDA)


The Metro Manila Development Authority’s (MMDA) services include urban development planning, solid waste disposal, flood control and sewerage management, urban, renewal and zoning, health and sanitation, urban protection, pollution control, public safety during calamities and/or disasters and transport and traffic management; the latter acting as the MMDA’s most visible function. Although the presence of MMDA traffic enforcers on the cities’ roads seem to be, for the most part, their greatest effort, there are a number of other traffic management initiatives they implement.

The Unified Vehicular Volume Reduction Program (UVVRP), more popularly known as the “number coding” scheme



The Unified Vehicular Volume Reduction Program (UVVRP) is what is more commonly referred to as the “color coding” or “number coding” system implemented by the MMDA. It is a travel demand management program meant to ration road space based on the license plates of vehicles; by regulating the number of vehicles using the roads, the program thereby reduces volume and eases traffic congestion.

The scheme was intended to be a temporary solution in light of the traffic congestion caused by infrastructure projects in the 1990’s. Despite that the UVVRP was not created to be a long-term policy, at present it is still being used and remains to be one of the MMDA’s most well-known traffic initiatives.

The first version of the UVVRP was implemented in 1995. During the 1990s, there were many road and railway infrastructure projects being built throughout Metro Manila; in order to address the resulting increase in congestion, the MMDA issued Regulation No. 95-001 or the “Odd-Even Scheme.” The scheme banned private vehicles with less than three passengers from passing restricted roads during AM and PM peak periods on particular days. The scheme banned private vehicles with less than three passengers from passing restricted roads during AM and PM peak periods on particular days. Vehicles in use for public transportation, emergencies, police and military, school buses, diplomatic matters and official media were exempted from this regulation.

On Tuesdays, Thursdays and Saturdays, vehicles with license plates that ended in odd numbers were restricted from use; while those that ended in even numbers were restricted from use on Mondays, Wednesday and Fridays. The peak periods during which the vehicles were banned were defined to be from 7:00-9:00 am and 5:00-7:00pm. Per violation, there was a P300 penalty charged to offenders.

Regulation 96-or the “Modified Odd-Even Scheme” was then issued in 1996. This scheme applied to public utility vehicles such as taxis, buses, public utility jeepneys, etc., which are banned from all streets of Metro Manila on particular days of the week from 9:00 AM to 5:00 PM based on the plate number ending of each vehicle, as follows: 1 and 2 on Mondays, 3 and 4 on Tuesdays, 5 and 6 on 7 Wednesdays, 7 and 8 on Thursdays, 9 and 0 on Fridays. This regulation took effect February 19, 1996 and covered all roads in Metropolitan Manila.

1996 was also the year the MMDA, adopted Regulation 96-005 entitled the “Unified Vehicular Volume Reduction Program” as a replacement of Regulations Nos. 95-001 and 96-004. This program aimed to regulate the operation of certain motor vehicles on all national, city and municipal roads in Metropolitan Manila. Under this scheme, private vehicles are banned for longer hours (i.e., between 7:00 AM and 7:00 PM).

In 2003, the UVVRP was modified to allow for a window time between 10:00 AM to 3:00PM which was considered to be the off-peak period within the day when restricted vehicles could travel along the specified roads. This scheme, however, was not uniformly adopted in all cities and municipalities throughout metropolis due to differing traffic conditions.

In 2010, the UVVRP included both public transportation and private vehicles under the scheme.

Today, the provision of the UVVRP are as follows: vehicles cannot drive around Metro Manila based on the last digit of the license plate. 1 and 2 are banned on Mondays, 3 and 4 on Tuesdays, 5 and 6 on Wednesdays 7 and 8 on Thursdays and 9 and 0 on Fridays. The period of the UVVRP is from 7am to 8pm without window hours and it applies to national, circumferential and radial roads in the metropolis.

The plate numbers restrained from driving within Metro Manila are summarized into this table:

Truck Ban Ordinance

The truck ban is a scheme meant to address the perception that freight vehicles are the main culprits in congesting Metro Manila roads. Under this scheme, trucks are prohibited from traveling along major road networks for most of the day, depending on the type and weight of truck. It has been in place since 1978 and restrains large trucks to designated routes in order to give way to other road users. Infractions of the ban carry a fine of P2000.



For trucks weighing more than 4,500 kilos, the truck ban is implemented accordingly:

From 6:00 a.m. - 10:00 a.m. and from 5:00 p.m. - 10:00 p.m. everyday except Sundays and Holidays, no cargo truck shall be allowed to travel or pass along:
 * España Street through Quezon Avenue from Echague Street to the intersection of West and South Avenue;
 * Claro M. Recto Avenue from Legarda St. to del Pan Street;
 * President Quirino Avenue from South Superhighway to Roxas Boulevard;
 * P. Burgos St. through Ayala Boulevard, Legarda St., Magsayasay Boulevard and Aurora Boulevard, from Roxas Boulevard to Boston Street;
 * E. Rodriguez Avenue through Bonifacio Avenue from Welcome Rotonda to Shoe Avenue;
 * South Superhighway through Nagtahan Bridge and Alfonso Mendoza Street from EDSA to Dimasalang Street;
 * Taft Avenue through Quirino Avenue from Redemptorist Street to Plaza Lawton, to include McArthur, Quezon and Jones Bridges;
 * Bonifacio Drive through Roxas Boulevard and NAIA Road to Aduana Street to the Ninoy Aquino International Airport;
 * Rizal Avenue through Rizal Avenue Extension from Carriedo Street to the Bonifacio Monument;
 * Reina Regente Street through Abad Santos Street from Regina Regente Bridge to Rizal Avenue Extension;
 * Makati District Business;
 * Ortigas Business District, Pasig City; and
 * Bonifacio Global City, Taguig City

For trucks weighing a total of 4500 kilos or lower, the ban applies as follows:

From 6am to 10 am, Monday through Saturday, cargo trucks are prohibited prom passing these certain roads
 * EDSA Southbound
 * Shaw Boulevard (from Mandaluyong City and Pasig City.)

From 5pm to 10pm, Monday through Saturday, cargo trucks are prohibited prom passing these certain roads
 * EDSA Northbound
 * Entire stretch of Shaw Boulevard

The ban was first applied in 1978 in recognition of the critical state of traffic congestion being experienced in Metro Manila through the Ordinance No.78-04. This act prohibited cargo trucks with a gross vehicular weight of over 4000 kilograms from driving along eleven major roads in Metro Manila during peak traffic hours (6:00 am- 9:00am, and 4:00pm-8:00pm) daily except on weekends.

The Department of Transportation and Communication issued Memorandum Circulars No. 90-367 in 1990 which repealed the previous truck ban schedule and changed it to the following:
 * 7:00am – 10:00 am on weekdays
 * 4:00pm – 8:00pm Monday-Thursday
 * 4:00pm – 9:00 pm on Fridays

In 1991, in response to the appeal for an alternate route and reduction of the truck ban, the MMDA issues Ordinance No. 19, amending the original Ordinance No. 78-04. This provided alternate routes to those included in the truck ban and allowed a 2-hour reduction of the truck ban period resulting in these effects:
 * 7:00am – 9:00 am on weekdays
 * 5:00pm – 8:00pm Monday-Thursday
 * 4:00pm – 9:00 pm on Fridays

This was further amended when Ordinance No. 5 Series of 1994 was issued. As a result, trucks were banned from the major arterial road Epifanio Delos Santos Avenue. This was an “all-day” ban that lasted from 6:00am – 9:00pm and was implemented Monday through Friday. It also restricted trucks from passing along 10 major routes between these particular hours: •	6:00am – 9:00am (daily with the exception of Saturdays, Sundays and holidays) •	5:00pm – 9:00pm (daily with the exception of Saturdays, Sundays and holidays)

Since then, the MMDA has issued Regulation No. 96-008 in 1996 thus extending truck ban to Saturdays; leaving only Sundays and holidays as the exception. This was done in desire to further reduce traffic congestion experienced throughout the week. The gross capacity weight of trucks was also changed from 4,000 kilograms to 4,500 kilograms by the issuance of Regulation No. 99-002.

U-Turn Scheme



The U-turn Scheme was implemented by the MMDA in 2002 primarily to account for roundabout operations on the road. This entailed the creation of median opens along busy arterial roads and was comprised of two originally separate schemes: the “Big Rotunda Scheme” and the “Clearway Scheme”.

Big Rotunda Scheme
 * Construction of median opening pairs
 * Closing intersection by use of temporary barriers

Clearway Scheme


 * Promote uninterrupted flow along arterial roads
 * Meant to speed up congestion along clogged roads

Essentially, the scheme resulted in the closing of many road intersections as well as the suspension of traffic signal operations in order to allow for the system of median openings. The set up of the U-turn scheme caused lanes of vehicles approaching an intersection to converge and thus be diverted into a single stream towards the U-turn.

The U-turn scheme was first applied along Commonwealth Avenue in Quezon City and Marcos Highway in Pasig and Marikina. Later on, the scheme was also implemented in other areas on Metro Manila including various intersections along EDSA.

Social Media Platforms

Since 2010, the MMDA has tapped into the use of social media such as Twitter, in an effort to alleviate the traffic situation. Through such platforms, the MMDA is able to broadcast live updates to their followers, send out and respond to tweets 24 hours a day. The Twitter feed is mostly used to relay information regarding traffic, accidents and number coding (UVVRP) updates.

Mobile Application: MMDA Traffic Navigator 

The MMDA Traffic Navigator was a mobile application launched in 2011 for android and iOS meant to give users quick access to traffic situations surrounding the Metro Manila’s major routes. It delivers real-time traffic updates in specific roads and highways by relying on CCTVs to assess the congestion in particular areas. In areas where there are no available CCTVs, reports are instead collected from traffic enforces. The application may be accessed via system view or line view; and provides indicators as to whether the current traffic is considered light, moderate or heavy.

New Bill filed by Senator Franklin Drilon
The traffic situation in Metro Manila, as well as in other urban cities, continues to get worse to the point that it has already affected the overall growth and development of the country. This led Senate President Franklin M. Drilon to file a new bill, which grants President Rodrigo Duterte emergency powers to help solve the traffic problem in the Philippines.

This new bill is also known as the “Transportation Crisis Act of 2016” and under this bill, the following are stated:
 * The President will be authorized to adopt alternative methods of procurement for the construction repair, rehabilitation, and improvement or maintenance of transportation projects (limited source bidding, direct contracting, repeat order, shopping, negotiated procurement, etc.)
 * The President will be allowed to reorganize the Department of Transportation (DOT) and its attached agencies, Land Transportation and Fare Regulatory Board (LTFRB) and the Land Transportation Office (LTO), as well as the MMDA

Furthermore, this bill aims at establishing a sole urban traffic management authority to streamline the management of traffic. According to Drilon, the MMDA should be the sole urban traffic management authority in Metro Manila and the DOT in other urban areas. This is because poor enforcement of traffic rules and the overlapping functions of government institutions contribute to the worsening traffic situation.

Drilon stated “The emergency power being sought for President Duterte will capacitate him in addressing the horrendous traffic situation within and outside Metro Manila. The emergency power is already a ‘necessity’ given the magnitude of the transportation crisis that not only impedes the mobility of people, goods, and services, but also threatens the livability of our cities.”
