The national significance of urban transit has been the subject of much debate in recent years. To place the various arguments in perspective, this article offers a brief overview of major developments in urban transit, particularly focusing on the effects of federal assistance, during the last twenty years.

In this paper some research questions which potentially lie within the purview of the new discipline of Computational Transportation Science are presented. Some of these questions are no doubt old and jaded and some may rightly reside in a different research field (or be seen as engineering) but viable solutions to all of the issues presented are of vital importance to the efficacy of future tr...

The very high cost of highway accidents paid by societies around the world makes the highway safety improvement an important objective of transportation engineering. The high speed cars are gaining popularity as one of the important means of transportation among the middle and higher income group of the society in India. At the same time the road accident statistics with regard to these high sp...

In this paper, we propose a multi-commodity, discrete kinematic wave model for simulating network traffic flow that possesses the theoretical rigor and computational efficiency inherent in the kinematic wave theory. In this model, 1Author for correspondence (Current address: Institute of Transportation Studies / University of California / 522 Social Science Tower / Irvine, CA 92697-3600 / (949)...

Recently, new approaches with commercial high-resolution satellite imagery in the engineering application domains have been attempted. Among them, uses of remotely sensed imagery linked with GIS-T (Geographic Information Systems for Transportation) or transportation geography are regarded as one of prospecting issues. As the matter of facts, most transportation applications are needed real-time...

This paper presents a general-purpose software framework dedicated to the evolutionary transportation scheduling, which is one of the most challenging areas in transportation engineering. Against evolution, the most popular approach is manual process. Manual process in here is to describe the system business using the most appropriate modeling language(s) at the most appropriate level(s) of abs...

In recent years, the feasibility of utilizing gas hydrates in industrial systems draws much attention as a subject of engineering studies. Despite the suggested applications for gas hydrate in transportation and storage of natural gas, desalination of water, etc., there have been few applied industrial experiences with gas hydrates. There are several patents and papers on promotion of gas hydra...

From our experiences in the past, we have seen that the growth of cities is very much dependent on the transportation networks. In mega cities, transportation networks determine to a significant extent as to where the people will move and houses will be built. Hence, transportation network data is crucial to an urban growth prediction system. Existing works have used manually derived distance b...
