the modern life‚ the number of transport has been increasing quickly is an important to cause to lead that transport pollution has been becoming serious. And it can bring many unpredictable impacts to humankind and ecosystem. So‚ many people think that if the governments want to less transport‚ they need invest and have reduction of price in public transport. Personally‚ I strongly agree this statement for some following reason. First of all‚ the amount of transport will decrease when the government

Public transport can be defined as a system of vehicles such as buses and trains which operate at regular times on fixed routes and are used by the public . In Malaysia ‚ the number of vehicle on the road has been increased in every year . It shows that the public now is affordable to have at least a motorcycle as their daily transport rather than use the public transport. The public should not use the public transport because the risk of being the criminal victim will increased ‚ the people need

Gaseous exchange and transport Movement of chemicals in plants and animals -Chemicals that are being moved into the body‚ within the body or out of the body are gases‚ this movement is known as gaseous exchange. -The gases being moved in our out of the body need to move across the surface area of the body‚ in most cases a special surface area has been developed. -The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion

become the third largest economy by the year 2025 after China and the USA and has awakened the interest of significant investors. The transport and logistics sector are fundamental to the development of a country‚ especially so in India where it is estimated to provide employment for 45 million people. Multimodal logistics serves to interconnect different modes of transport – road‚ rail‚ air‚ water – and therefore improve efficiency and speed of goods movement. The economic growth in India has increased

Traffic Congestion 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 the traffic demand is great enough that the interaction between vehicles slows the speed of the traffic stream‚ this will results in some congestion. As demand approaches the capacity of a road (or of the intersections along the road)‚
