The generalized traveling wave method (GTWM) is developed for the nonlinear Schrödinger equation (NLSE) with general perturbations in order to obtain the equations of motion for an arbitrary number of collective coordinates. Regardless of the particular ansatz that is used, it is shown that this alternative approach is equivalent to the Lagrangian formalism, but has the advantage that only the ...

-Regulatory agencies in the energy field have suoeessfully used incentives to encourage lectric and gas utilities to implement conservation measures. We develop a method for allocating federal and state funds to reward local governments that adopt effective travel demand management measures and reduce the need for expenditures on expanded roadway capacity. This method is applied to Sacramento u...

There is emerging evidence that personal daily travel, particularly by car, has ceased to grow in the developed economies. This can be attributed to saturation of demand, given high levels of access and choice now widely available, together with constraints on higher speeds. We are therefore at a time of transition from an era of growth of per capita travel to an era of stability, in which the ...

Activity-based models of travel demand have received considerable attention in transportation planning and forecasting over the last few decades. FEATHERS (The Forecasting Evolutionary Activity-Travel of Households and their Environmental Repercussions), developed by the Transportation Research Institute of Hasselt University, Belgium, is a micro-simulation framework developed to facilitate the...

Considerable amount of research efforts has been dedicated to conceive forecasting models for predicting urban development and travel demand. Mainly originated from the application of economic theory, urban development models were initially conceived to explain the configuration and evolution of urban structures (Chapin, 1957). According to Ross (1988), these models are used to predict how futu...
