The Dis-Economics of Speed Limit

SSRN Electronic Journal, 2013
Speed limit is imposed for some purposes: oil saving and safety, for example. This paper proves that none is justified. Speed limit reduces road capacity, or equivalently stated more roads are needed for the same traffic flow. This paper shows how traffic economists have misunderstood the traffic flow curve, and that some even have mistook it as a ...

Economics and Politics of High-Speed Rail

2012
The technological revolution linked to high speed rail (HSR) has been accompanied by myths and claims about its contribution to society and the economy.

Economics of AC Adjustable Speed Drives on Pumps

IEEE Transactions on Industry Applications, 1975
Flow control of pumps with adjustable speed ac drives can be very economical. Pump and system head/flow characteristics are reviewed, with suggestions for estimating the pump characteristic and efficiency at reduced speed. Generalized pump and savings curves are then developed to permit quick checking of the economics of adjustable speed flow control ...

Simulation of Correlated Wind Speed Data for Economic Dispatch Evaluation

IEEE Transactions on Sustainable Energy, 2012
The Economic Dispatch problem consists of minimizing the cost of producing the power demanded by an electrical power system, by means of the suitable dispatching of the power production between the available generators. The difficulty in predicting wind power generation means that penalty and reserve costs must be considered when it is included in the ...
