New York City is constantly finding ways to improve its transportation system to reduce traffic congestion on its streets and protect pedestrians from vehicular attacks. New York City undertakes these improvements through the addition of a new subway line, annual limits on Uber and Lyft, and the placement of concrete barricades on sidewalks. However, these attempts to improve the transportation system have caused setbacks that have affected the health of commuters, the income of immigrant minorities, and caused increased congestion on sidewalks. Subway lines are ideal for improving traffic congestion on the street, as they offer commuters the option of traveling by subway trains, instead of suffering in traffic when driving a car on New York City streets. Before the subway, in the 1970s, New York City thought it was ideal to have minibuses carrying twenty to thirty people around the city, and for these buses to travel in their own lane, closed to public vehicles. However, the subway has proven to be a more efficient way to move people in urban cities with ever-advancing technology and a growing population. Say no to plagiarism.

As I learned in class, about 55% of the world's population lives in urban cities like New York, and in the future the percentage will increase to about 66%. Therefore, subway lines are important for the movement of people, as they will promote efficient travel rather than promoting car driving which will only increase traffic on the road. As a result of this perceived reduction in cars on the road, this will reduce outdoor vehicle pollution, creating a healthier environment for those living in or visiting New York City, especially tourists, as New York is a very well-known city for its tourist attractions. However, this introduces another problem: what is the air quality like underground? In Barcelona, ​​the air quality in the metro lines and in the streets was compared and it was found that the air quality in the metro lines was worse, while air pollution was higher underground. However, there were no short-term negative effects on the respiratory health of people building or riding the subway, as in Stockholm, likely due to the fact that safety precautions had been taken before the subway was built. In which, New York City must properly regulate the air quality in subway lines to avoid contradictions in reducing air pollution in New York City. Therefore, New York City must invest money not only to improve transportation for people by creating subway lines, but also to maintain healthy air quality for commuters to move around the city. To further reduce traffic congestion on New York's streets, the city has placed a limit on the number of Uber/Lyft drivers on the road. Uber and Lyft are relatively new transportation services that essentially work the same way as a yellow cab or New York City cabs. The difference between a New York taxi and an Uber/Lyft car is that screening for Uber and Lyft drivers is much more lenient. This means.
