In the first place, than they are able to perceive a potential situation, recognise it as a threat, properly decide what would be the best way of reacting to it, react to it and allow enough time for the remedy, like stopping or swerwing in time, to take effect - in the road traffic contexts this is called the typical reaction time of a driver. In order to determine the safest speed limit the EFFECTIVE average reaction time of the majority of road users must be used (effective reaction time = average human reaction time + a reasonable extra margin of time for safety reasons). The probable distance at which the average driver will usually first see a potential threat is also important in calculating the safest speed limit for the area as this will determine the time available to effective react before the driver reach the spot where the threat's at. The probable distances to threat keeps getting shorter as traffic congestion is increasing leaving less and less effective reaction time for drivers - so speed limits should be lowered instead of increased for safety sake.

Apr 24, 2017It is agreed that our cities have become one big traffic jam. This essay will discuss the factors Post your writing Feedback, suggestions and.
The most obvious reason traffic congestion has increased everywhere is population growth. In a wealthy nation, more people means more vehicles. But total vehicle mileage traveled has grown much faster than population. From 1980 to 2000, the total population of the United States rose 24 percent, but total vehicle miles traveled grew 80 percent because of more intensive use of each vehicle. The number of vehicles per 1,000 persons rose 14 percent and the number of miles driven per vehicle rose 24 percent. Even without any population gain in those two decades, miles driven would have risen 47 percent.Another factor in road congestion is accidents and incidents, which some experts believe cause half of all traffic congestion. From 1980 to 2000, the absolute number of accidents each year has remained amazingly constant, and the annual number of traffic deaths in the United States fell 18 percent, in spite of the great rise in vehicle miles traveled. So accidents could only have caused more congestion because roads were more crowded, and each accident may now cause longer back-ups than before.The most obvious reason traffic congestion has increased everywhere is population growth. In a wealthy nation, more people means more vehicles. But total vehicle mileage traveled has grown much faster than population. From 1980 to 2000, the total population of the United States rose 24 percent, but total vehicle miles traveled grew 80 percent because of more intensive use of each vehicle. The number of vehicles per 1,000 persons rose 14 percent and the number of miles driven per vehicle rose 24 percent. Even without any population gain in those two decades, miles driven would have risen 47 percent.Today traffic congestion is one of the fundamental problems of modern cities, however there are some possible adjustments, that should be taken by both local and central administrations, to decrease traffic jam.
One of the main reasons of traffic congestion is the number of personal cars in traffic. City people prefer to use their own car for transportation. As a result, cities are having more cars in the public roads than predicted. I think number of cars can be restricted from the traffic by applying some regulations. For instance; the authorities might legislate new rules like apply charge to personal car owners who want to use his/her car for their daily transportation. People could be discouraged by using their own cars because they have to pay extra money for this. Therefore they begin to use public transportation inside city.
The other main reason of traffic congestion is the increasing crowd in the big cities. Most of the people think that big cities’ facilities are higher than others that’s why they immigrates to those cities. Consequently big cities become more crowded. I think authorities have to find solutions to prevent immigration. As a solution the other cities’ living standards and facilities could be enhanced. If the central administration can provide the same standards to the all cities the crowd in cities can be reduce and the traffic congestion decreases parallel to this.
As a conclusion; the big cities’ one of the most important problems, traffic jam can be reduced by taking important steps.
