Highway relief routes around smallor medium-size communities are an important element of the Texas Trunk System. These routes provide for the safe and efficient movement of through traffic and contribute to the growth of the Texas economy. For smalland medium-size communities, however, highway relief routes potentially bring both positive and negative impacts by reducing the flow of traffic thr...

The Dial-a-Ride Problem (DARP) consists of designing vehicle routes and schedules for n users who specify pick-up and drop-off requests between origins and destinations. The aim is to plan a set of m minimum cost vehicle routes capable of accommodating asmany users as possible, under a set of constraints. The most common example arises in door-to-door transportation for elderly or disabled peop...

Route bus system is fundamental transportation device for aged people, and have important role in every province. However passengers decreases year by year. Therefore we have developed the shortest path searching system called “BUS-NET” to sustain the public transport. Here, generation of timetables is picked up. In general, it is considered as very simple problem, however the route bus system ...

in our country, school bus routes are determined by experiments of driver without considering the scientific optimum route and location. traversing additional routes will always result an increase in vehicle movements and fuel consumption and enormous costs. hence, this paper will study the school bus routing in tehran considering special students and a model will be presented to minimize trave...

turkey as a country located between the main energy resources and the european :union: can play the role of a natural bridge in energy transportation. the eu countries have always tried to find some alternative routes for russian energy pipelines and turkey could be one of the best options. although turkey is poor in oil and natural gas resources, however, this country can play a strategic role...

The pick-up and delivery problem (PDP) consists in finding a set of optimal routes for a fleet of vehicles respecting the precedence and pairing constraints and visiting all transportation requests. The transport of personnel on oil platforms is a real application of PDP which we are interested in. The problem is modeled as a set covering problem that is solved via a column generation technique...
