High Speed Ground Transportation in California

Potential demand for passenger travel to orbit
In recent years the possibility of `space tourism', that is individual passenger travel to space on a commercial basis, has received increasing attention. The possibility of such an activity...

Inter-stellar Propulsion: The Need for Speed
Interstellar travel is certainly one of mankind's next step to reach for the stars. Four ideas for interstellar propulsion are discussed in this paper: the Orion Project, Deep Space Ramjets,...

A Comparison of Propulsion Systems for Space Exploration
There are three promising propulsion systems that might be used for space missions: chemical, direct nuclear, and nuclear electric. Selecting the best system for a mission involves comparing...

Transfer Vehicle Sizing for Missions to Mars
The purpose of this study is to analyze the interactions between mission and vehicle design parameters, and determine how the selection of a particular trajectory and transit time affects...

California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...

Rail Service to Airports
Rail service is available at seven North American airports, and service is available by a shuttle bus connection at more than nine other North American airports. Additionally, rail service...

Switzerland: Rail Access to Airports and the Fly-Luggage System
Swissair and the Swiss Federal Railways (SBB) offer a unique service for air passengers travelling to and from their Swiss airport of departure or arrival. In conjunction with private...

Flushing Flows for the Water Manager

Recent Advances In Well Hydraulics
Most books and papers on well hydraulics are mostly or entirely aquifer hydraulics. The phrase, 'well hydraulics,' implies a study of the flow into and within a well proper. There has...

A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...

Analysis of Potential Highway Routes to Yucca Mountain

Strategic Ship Routing Impacts of Temporal Coverage with Real-time Satellite Altimeter-Based Current Information
We investigate strategic ship routing impacts of temporal coverage with real-time satellite altimeter-based current information. We sample underlying daily `true' current patterns along...

Demand/Supply Relationship in Transportation Network Design Problems: A Genetic Algorithm Approach
The cumulative genetic algorithm (CGA) has its significant advantages over the heuristic algorithms in dealing with transportation network design problems. Using CGA, the entire solution...

Best Route GIS System
A GIS systems was developed for determining the best route to travel, so that the traveler will travel to a number of cities in such a way that he/she will visit each city only once and...

Electronic Yellow Pages for Pre-trip Planning Systems
An attempt has been made to introduce Electronic pages or Electronic yellow pages which work similarly to Yellow Pages. The overall system is divided into user interface, network building,...

Data Fusion for an ATIS Operational Test: Description and Computational Issues
The ADVANCE project in the Chicago Metropolitan area is the largest operational test of Advanced Traveler Information System (ATIS) technologies in the U.S. This paper focuses on the process...
