Infrastructure Planning in Beirut, Lebanon
This paper presents a comprehensive framework for structuring the decision process of planning for transportation infrastructure rehabilitation and development in the city of Beirut, Lebanon....
Digital Imaging as a Design Tool
On most engineering projects, schematic drawings offer a technical representation of a structure to clients. For staff or the public who are not technically knowledgeable, though, schematics...
Establishing a HSGT System Organization
Most of the attention on High Speed Ground Transportation systems thus far has been devoted to their technological, financial and construction aspects, and this was understandable since...
High Speed Ground Transportation on U.S. East Coast
The United States has entered into a new era of need for domestic improvement. The demand for high speed transportation far exceeds the supply. The increasing congestion of our roads and...
Development of Simulation and Cost Models to Compare HSR and Maglev Systems
Both high-speed rail (HSR) and magnetically levitated systems offer comfortable and safe ground transportation at high speed. The cost structure and performance of these systems and their...
The Megabight Barrier / Maglev Way?Innovative Siting of High Speed Ground Transportation...Offshore
Air and road traffic congestion around cities, e.g., in the BOSWASH corridor, can be reduced by high speed rail systems. But high speed trains on elevated rails/guideways encounter extra...
The Force Between a Bogie and a Troubled Suspension and Guidance Coil
It is very important for the superconducting LSM Maglev vehicle to maintain the safety. Currents induced in suspension and guidance coils arranged on the side wall of a guide way generate...
Maglev Sensor and Communications System Integration
This paper presents an assessment of the communications and sensor technology integration necessary to assure safety of high-speed transportation on the ground. Candidate architectures...
Safety Hazards of Maglev Guideway and Route Integrity
This paper presents an assessment of safety hazards associated with high-speed transportation on the ground. Hazard sources and consequences are identified through establishment of system...
High Speed Rail Loading Scenario and Dynamic Tuning of Track
Similarities and differences exist between conventional and high speed rail (HSR) infrastructure design. The differences stem from the dynamic nature of the HSR loading scenario and the...
