An analysis of the reasons why there is heavy traffic

how to reduce traffic congestion

While you can use brakes to signal that you are slowing down, you should avoid sudden braking as it is likely to cause crash. Taking time is never a waste of time; it is a rather small price for safety. Statements consisting only of original research should be removed. Congested roads can be seen as an example of the tragedy of the commons.

Road rage can lead to altercations, assaults, and collisions which result in injuries and even deaths. Highway Performance and Monitoring System forandas well as information on population, employment, geography, transit, and political factors. Do not speed Accidents often occur even when there is enough inter-vehicle distance, because the speed of the oncoming vehicle is much faster than it appears.

Drivers with stronger desire to arrive at their destination as soon as possible are more likely to take risks. Stressed and frustrated motorists, encouraging road rage and reduced health of motorists Emergencies: blocked traffic may interfere with the passage of emergency vehicles traveling to their destinations where they are urgently needed.

Traffic congestion occurs when a volume of traffic or modal split generates demand for space greater than the available street capacity; this point is commonly termed saturation.

Causes of traffic jam

Many traffic jams leave drivers baffled as they finally reach the end of a tail-back to find no visible cause for their delay. Indeed, it is extremely difficult to accurately judge the speed of an oncoming vehicle from a distance. Speeding further compounds this difficulty. Wasted fuel increasing air pollution and carbon dioxide emissions owing to increased idling, acceleration and braking. According to the characteristics of CSOs, we suggested that the regulatory of CSOs focus on the source, pipes and ends of the drainage system. There are a number of specific circumstances which cause or aggravate congestion; most of them reduce the capacity of a road at a given point or over a certain length, or increase the number of vehicles required for a given volume of people or goods. The model predicts that this is a very typical scenario on a busy highway above 15 vehicles per km. Shown here is a traffic jam in Delhi. The result of this is that several miles back, cars would finally grind to a halt, with drivers oblivious to the reason for their delay.

Unsafe road environments Unsafe road environments refer to external factors uncontrollable by drivers, such as visibility impairment by darkness, slippery surface, insufficient safety facilities, inadequately repaired vehicles, pedestrians or other vehicles that suddenly get in the way.

Wear and tear on vehicles as a result of idling in traffic and frequent acceleration and braking, leading to more frequent repairs and replacements.

Speeding is even more dangerous at night because visibility is reduced and light traffic tempts many other drivers to speed. Their working traffic models typically use a combination of macro- micro- and mesoscopic features, and may add matrix entropy effects, by "platooning" groups of vehicles and by randomising the flow patterns within individual segments of the network.

Traffic problems and solutions

About half of U. In short, abiding by traffic regulations is the most basic preventive measure against traffic accidents. Rapid economic growth in China has resulted in a massive increase in the number of private vehicles in its major cities. Many risk heavy fines, license suspension, and even traffic accidents just to save a few minutes. According to a report published by the United States Census Bureau , a total of It has been found that individual incidents such as accidents or even a single car braking heavily in a previously smooth flow may cause ripple effects a cascading failure which then spread out and create a sustained traffic jam when, otherwise, normal flow might have continued for some time longer. While you can use brakes to signal that you are slowing down, you should avoid sudden braking as it is likely to cause crash. Abide by traffic regulations Everyone expects pedestrians and drivers to comply with traffic regulations. Now, a team of mathematicians from the Universities of Exeter, Bristol and Budapest, have found the answer and published their findings in leading academic journal Proceedings of the Royal Society.
