In my report I will talk about road traffic , and I think it is very important to know about it because it is very common issue these days and people do not know how to deal with it, so I want to define the road traffic in simple way and find some solutions to this problem. Therefore, I will divide the report into four sections. The first section will give a background to road traffic , and then the second one will describe the causes of road traffic . After that, I will mention the effects of road traffic and the damage they cause it globally. Finally, I will give some solutions to avoid the road traffic.
Traffic congestion is a condition on road networks that occurs as use increases, and is characterized by slower speeds, longer trip times, and increased vehicular queuing. The most common example is the physical use of roads by vehicles. When traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream, congestion is incurred. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is colloquially known as a traffic jam.
Traffic congestion occurs when a volume of traffic or modal split generates demand for space greater than the available road capacity, this is point is commonly termed saturation. 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. About half of U.S. traffic congestion is recurring, and is attributed to sheer weight of traffic; most of the rest is attributed to traffic incidents, road works and weather events. Traffic research still cannot fully predict under which conditions a "traffic jam" (as...
