Cable transport is a broad mode where vehicles are pulled by cables instead of an internal power source. It is most ...
For instance, it appears to compare different kind of roads in some publications as it had been computed on a five-year period between 1995 and 2000. [8] In the United States, it is computed per 100 million miles traveled, while internationally it is computed in 100 million or 1 billion kilometers traveled.
[47] [48] City buses produce about 0.3 kg of CO 2 for every mile traveled per passenger. For long-distance bus trips (over 20 miles), that pollution drops to about 0.08 kg of CO 2 per passenger mile. [49] [43] On average, commuter trains produce around 0.17 kg of CO 2 for each mile traveled per passenger.
Friction of distance is a core principle of geography that states that movement incurs some form of cost, in the form of physical effort, energy, time, and/or the expenditure of other resources, and that these costs are proportional to the distance traveled.
