GAO-02-1075T Mass Transit: Challenges in Securing Transit Systems
We appreciate the opportunity to speak with you today about mass transit safety and security in the United States. Over a year has passed since the terrorist attacks of September 11, 2001, realigned our national priorities. While most of the early attention following the September 11 terrorist attacks focused on airport security, emphasis on the other modes of transportation has since grown. Mo...
متن کاملOn the regional mass transit assignment
This paper considers a mass transit system in a regional area. The problem of improving the quality of the service in terms of costs perceived by the passenger is studied. A model to improve the effectiveness of the system maintaining the feasibility of the traffic assignment is proposed, along with new definitions of passenger assignment to support the proposed model.
متن کاملA Large Mass Transit System With Failures
In the field of Empirical Modelling, much has been written and many models created relating to transport systems. However, most of this work has focussed on small-scale systems of a few manually modelled places. There is much to be gained from taking a wider view of a transport system and how it reacts to local conditions. The model accompanying this paper attempts to do so, including various k...
متن کاملTelescope search for the transit of the Earth - mass exoplanet
Results from exoplanet surveys indicate that small planets (super-Earth size and below) are abundant in our Galaxy. However, little is known about their interiors and atmospheres. There is therefore a need to find small planets transiting bright stars, which would enable a detailed characterization of this population of objects.We present the results of a search for the transit of the Earth-mas...
متن کاملCoherent Network Optimizing of Rail-Based Urban Mass Transit
An efficient public transport is more than ever a crucial factor when it comes to the quality of life and competitiveness of many cities and regions in Asia. In recent years, the rail-based urban mass transit has been regarded as one of the key means to overcoming the great challenges in Chinese megacities. The purpose of this study is going to develop a coherent network optimizing for railbase...
