Traffic congestion has a number of negative effects:

Una de las consecuencias de la congestión vehicular son los contaminantes atmosféricos. Estos se pueden clasificar en dos grandes grupos:.

Contaminantes primarios: Aquellos que son introducidos en la atmósfera directamente a raíz de los fenómenos que los causan.

Contaminantes secundarios: Los que se forman en la atmósfera a partir de la presencia de contaminantes primarios.

Examples of pollutants and their effects

Every time traffic congestion occurs, air pollutants increase, which directly harms the health of people trapped in traffic jams or traffic jams. However, the effect goes further, as they also harm vegetation and ecosystems, cause material damage, noise pollution, among many other negative effects.

Pollutants produce a wide variety of health effects, among the main ones are: asthma, effects on neonatal development, increased sensitivity in the airways and chronic respiratory diseases), cancer (mainly lung) and cardiovascular arrhythmia), among others. In addition, we have effects that do not attack human health, however, they do affect them. Examples of this are absenteeism from work, days with restricted activity, behavioral effects, etc.

Once we analyze the above, we realize the importance of good road planning in cities. The objective of this is to help vehicles flow properly to avoid stagnation. But this does not always happen like this. An example of this is seen in Mexico City. To facilitate vehicular traffic, second floors were built on important communication routes. However, in order to use them, it is necessary to pay to circulate there, which leads to new chaos, since many citizens are not satisfied with the regulations. fees that are charged. In the end, the second floors do not benefit the entire population, since not everyone can add the payment of this new tax to their expenses.

Vehicular congestion occurs when the volume of traffic or the normal distribution of transportation generates a demand for space greater than that available on the roads. There are a number of specific circumstances that cause or aggravate congestion. Most of them reduce the capacity of a road at a certain point or during a certain period, or increase the number of vehicles necessary for a certain flow of people or goods. In many highly populated cities, traffic congestion is recurrent, and is attributed to the high traffic demand. Most of the remainder is attributed to traffic incidents, road works and weather events. Speed ​​and flow can also affect network capacity, although the relationship is complex.

It is difficult to predict under what conditions a "traffic jam" or "jam" occurs, as it can occur suddenly. It has been found that incidents (such as accidents or even a single heavily braked vehicle in a previously good flow) can cause repercussions (a cascading failure), which then spread and create a sustained traffic jam, when otherwise the normal flow may have continued for some time longer.

In cities like San Salvador (El Salvador, Central America) the cause is the number of cars (reaching 4 million).
