This report describes ways to make transportation planning evaluation more comprehensive and multi-modal. Conventional transport planning is mobility-based, it assumes that the planning objective is to maximize travel speed, and evaluates transport system performance based primarily on motor vehicle travel conditions. A new paradigm recognizes that the ultimate goal of most transport activity i...

this study presents a detailed analysis of cost management for intensive cultivation activity in terms of tomato production. the main objective was to provide qualitative and quantitative costs obtained in the intensive cultivation of tomato. this methodology was structured by activity costs (soil preparation and planting, crop monitoring, harvesting, selling, etc.) through a study in greenhous...

The lack of market development in remote areas is usually measured by the prices for a given set of consumer goods. We focus instead on the way distance constrains the variety in choices facing consumers. We construct a model of monopolistic competition between traders. An increase in transport costs reduces consumer welfare not only through lower incomes and higher prices but also through redu...

The Department of Defense (DoD) Environmental Security Technology Certification Program and the Environmental Protection Agency sponsored a project to evaluate the benefits and utility of contaminant transport simulation-optimization algorithms against traditional (trial and error) modeling approaches. Three pump-and-treat facilities operated by the DoD were selected for inclusion in the projec...

Consider the problem of optimally matching two measures on the circle, or equivalently two periodic measures on R, and suppose the cost c(x, y) of matching two points x, y satisfies the Monge condition: c(x1, y1)+ c(x2, y2) < c(x1, y2)+ c(x2, y1) whenever x1 < x2 and y1 < y2. We introduce a notion of locally optimal transport plan, motivated by the weak KAM (Aubry–Mather) theory, and show that ...

We address the Monge problem in metric spaces with a geodesic distance: (X, d) is a Polish space and dN is a geodesic Borel distance which makes (X, dN ) a possibly branching geodesic space. We show that under some assumptions on the transference plan we can reduce the transport problem to transport problems along family of geodesics. We introduce three assumptions on a given dN -monotone trans...

An efficient molecular motor would deliver cargo to the target site at a high speed and in a punctual manner while consuming a minimal amount of energy. According to a recently formulated thermodynamic principle, referred to as the thermodynamic uncertainty relation, the travel distance of a motor and its variance are, however, constrained by the free energy being consumed. Here we use the prin...

A sustainable transport system needs a cost accounting and full cost-pricing systems reflecting economicfactors which originate from transport activity inhibiting sustainable development (namely, externalities; spillovereffects and non-priced inter-sectorial linkages; public goods; uncompetitive markets; myopic planning horizonsand high discount rates; risk and uncertainty, irre...

We consider the travelling salesperson game (TSG) in which agents correspond to a set of locations, and the cost of each subset of locations is the length of the optimal tour for that subset. The Shapley value, one of the most important normative division schemes in cooperative games, is a principled way of dividing transport costs among such locations. We prove that approximating the Shapley v...
