Instead of RoLa :D.
Title of idea (in 2010, maybe i rewrite this...) 2.) A new, more efficient way of intermodal(railway/highway) transportation. Exploit the benefits of both railway and highway transportation and minimize their drawbacks by optimally mixing the two methods. Railway transportation between two points is cheaper and more environmentally friendly, than highway transport, however the later has the advantage of higher flexibility. Below we describe the case of single delivery of goods between two locations, however the method can be generalized to multi point delivery as well. Suppose that a company having only a single tractor has to deliver N trucks of goods, to a location (B) that is M km away from the starting point (A) on road and after that the tractor has to return to A. Suppose also that the combined distances of nearest railway stations from points A and B is R., while the distance between these stations over the railway is L, and the cost of transporting a truck 1...
