Allocating and routing problems in the field of transportation engineering are generally solved using the objective function of minimizing transport cost. Transport risk is a main concern in hazardous material transportation, mainly dependent on the vision of decision makers (national and/or local authorities). In this research work, a trade-off approach has been proposed to determine the safes...

The field of Engineering Systems maintains that fundamental engineering principles exist, which apply across different domains of complex socio-technical systems. In this thesis, a state-of-the art decision and design evaluation method developed using aerospace cases, Multi-Attribute Tradespace Exploration (MATE), is applied for the first time to a transportation design problem. Through the app...

Directional liquid transportation is important for a variety of biological processes and technical applications. Although surface engineering through asymmetric chemical modification or geometrical patterning facilitates effective liquid manipulation and enables water droplet self-transportation on synthetic surfaces, self-transportation of oil droplets poses a major challenge because of their ...

Directed graphs are ubiquitous in most aspects of software analysis. Presented abstractly, as a list of edges, a graph does not manifest much of the important structural information that becomes obvious if the graph displayed pictorially. This paper presents a technique for drawing directed graphs quickly and attractively. It also describes how a tool implementing this technique has been used, ...

When increasing use of the private automobile intensified street traffic congestion, cities, generally pursued one or two types of policies. The "Car accommodation policy" was aimed 'primarily at accommodating the car and highway traffic, neglecting all other modes. The "Balanced transportation policy" was directed to achievement of a co-ordinated system of different transportation modes. The f...

1.0 Introduction Transportation agencies across the U.S. are challenged in their efforts to engage the public in the problems of prioritizing regional transportation improvement projects--such as highway expansions or new light rail lines--and determining how to fund such improvements. These decisions are typically shaped by a variety of local, state, and federal laws as well as the competing t...

rivers are among the most important surface water resources which have always been of significance throughout the history of mankind. this significance is due to human dependence on water for answering his needs such as agriculture, water transfer, flood control and water transportation. in the past, it was assumed that basic measures such as exploiting rivers or managing floods were only limit...
