CHARLES HORTON COOLEY'S THEORY OF TRANSPORTATION: TOWARDS AN INTERACTIONIST APPROACH FOR TRANSPORTATION STUDIES

Towards Sustainable Urban Transportation Case Studies

Climate change is one of the greatest environmental, economic, and social challenges of our time. Urban transportation has had a major negative impact on our environment—most of our air pollution comes from transport. This paper explores ways to move toward a more sustainable transport system by focusing on creating a more efficient and livable city and improving the environmental efficiency of...

Transportation planning for disasters: an accessibility approach

A methodology is developed in this paper for evaluating and enhancing the performance of urban transportation systems in the aftermath of a disaster. A performance measure is proposed for assessing overall and distributional impacts based on the concept of accessibility. The methodology is demonstrated with two case studies. The first focuses on passenger railroad disruption in the catastrophic...

An Interactive Approach for Bicriteria Transportation Problems

An interactive approach for Bicriteria Transportation Problems, allowing for non-integer solutions, is presented. The decision-maker (DM) conducts the search by introducing upper bounds on the values of one or both criteria, adding one/two additional constraints to the original problem structure. So, usual algorithms for solving transportation problems cannot be used. Two extensions of the netw...

A New Approach for Finding an Optimal Solution for Grey Transportation Problem

In ordinary transportation problems, it is always supposed that the mileage from every source to every destination is a definite number. But in special conditions, such as transporting emergency materials when natural calamity occurs or transporting military supplies during wartime, carrying network may be destroyed, mileage from some sources to some destinations are no longer definite. It is u...
