An integrated urban transportation system usually consists of multiple transport modes that have complementary characteristics of capacities, speeds, and costs, facilitating smooth passenger transfers according to planned schedules. However, such an integration is not designed to operate under disruptive events, e.g., a signal failure at a subway station or a breakdown of a bus, which have ripp...

Although rail transportation is conventionally considered to be environmentallyfriendly, currently research is being carried out globally to find ways to improve energy-saving in rail transportation. Development of an energy management system for railways and new transport systems including the BRT (Bus Rapid Transit) system has begun. The railway energy management system manages and controls t...

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 urban transportation network is made up of vehicles in motion, dynamic static and moving obstacles. These obstacles block the path of the moving vehicles thereby causing traffic jam. Thus it is important to model the network explicitly and to describe the movement of the vehicle and obstacles relative to the transportation network. In this study the researchers have addressed the : (i) prob...

Previous urban sprawl studies have typically taken a cross-sectional approach without examining how sprawling urban areas are performing over time. Longitudinal studies of individual or household travel behavior and built-environment preference have made some progress in this direction, but very few studies have explored the longitudinal interaction of urban form with transportation and environ...

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...

land use planning is the main core of urban planning and one of the main components of an urban system. this element has close relation with transportation system of the city, so if their interaction becomes insufficient, deterioration and chaos would have an adverse impact on the urban system and would cause serious environmental issues. the integrated land use-transportation models seem to b...
