The National Transportation System (NTS), an outgrowth of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA), is proposed in this research as an analytical tool to guide national transportation policy-making. The NTS must be based upon measures of transportation performance that are intermodal, user-oriented,. and suitable for tracking the environmental, social, and economic o...

Many problems in transportation can be represented as flow problems, and can be optimally solved using efficient linear programming techniques [BIIM77] [BGAB83]. But in some cases this approach is seriously oversimplified. If the problem includes dependencies between different operations, planning is necessary. If the system parameters change dynamically, the assumptions on which flow models ar...

Overview There has often been an uneasy relationship between politics and planning in the selection of the policies and investments that shape urban areas. Competing interests vie to shape these decisions through the political process, while planning attempts to rationalize the process through analytical methods. Experience has shown that politics all too often trumps analysis, leaving both sid...

Federal and state transportation laws require that a long range transportation plan (LRTP) be developed in urban areas of greater than 50,000 people. The agency responsible for conducting the long range transportation planning process is the Metropolitan Planning Organization (MPO). The Florida Metropolitan Planning Organization Advisory Council (MPOAC) assists individual MPOs in carrying out t...

the goal of this paper is to develop a decision support system (dss) as a journey planner in complex and large multimodal urban network called rahyar. rahyar attempts to identify the most desirable itinerary among all feasible alternatives. the desirability of an itinerary is measured by a disutility function, which is defined as a weighted sum of some criteria. the weights represent travelers’...

We review urban models useful in transportation planning, focusing especially on ones that are based on geographic information systems (GIS) software. We then describe UPlan, a simple model written by us in the ArcView GIS. Several different applications of UPlan are outlined, involving transportation planning and the analysis of the growthinducing effects of new facilitites, to demonstrate its...

In the academic and professional literature on freight transportation, computer-based planning methods have a long time ago been identified as a means to achieve cost reduction through enhanced transportation operations efficiency. More recently, inter-firm collaboration in transportation planning has been investigated as a means to provide further gains in efficiency and, in turn, to achieve a...

Plug-in Electric Vehicle (PEV) charging stations couple future transportation systems and power systems. That is, PEV driving and charging behavior will influence the two networks simultaneously. This paper studies optimal planning of PEV fast-charging stations considering the interactions between the transportation and electrical networks. The geographical targeted planning area is a highway t...
