Valuation and Crediting Approaches for Transportation and Metropolitan Planning Agencies

Cooperative Planning of Metropolitan Transportation Facilities

The need for cooperation in the planning of metropolitan trans­ portation facilities has taken on added significance as a result of the Interstate Road Program with its emphasis on arterial improvement in urban areas. A meeting to discuss this problem more fully was held in October 1958 at Syracuse University. This meeting, the National Conference on Highways and Urban Redevelopment (more commo...

Temporal planning for transportation planning and scheduling

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...

Look-Ahead Approaches for Integrated Planning in Public Transportation

In this paper we deal with three consecutive planning stages in public transportation: Line planning (including line pool generation), timetabling, and vehicle scheduling. These three steps are traditionally performed one after another in a sequential way often leading to high costs in the (last) vehicle scheduling stage. In this paper we propose three different ways to “look ahead”, i.e., to i...

Comparison between Combined and Separate Approaches for Solving a Location-Routing Problem in Hazardous Materials Transportation

In the case of hazardous materials management, selected routes for carrying hazardous materials (i.e., hazmat) have significant effects on locating hazmat distribution centers. Since, risk and cost are usually considered as two main attributes to determine the best routes, optimized locations are sequentially outlined depending on selected routes. In the present paper, t...
