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...
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,...
Validation and Application of THE Model's Trip Table Estimation Process
The Highway Emulator (THE) Model is a microcomputer based travel demand forecasting program maintained by the Central Transportation Planning Staff (CTPS). In addition to the traditional...
Policy Options and Highway Capacity Needs
One of the recurring criticisms levelled against FHWA's Report to Congress on the Status of the Nation's Highways is that the Report does not go far enough in examining the implications...
Corridor Analysis Using QRS II Route 9 Case Study
This traffic modeling project is part of a larger planning study of the Route 9 corridor through the Town of Hadley and parts of Amherst and Northampton. The Pioneer Valley Planning Comission...
Travel Demand with Forecasting Microsimulation
Transportation planners forecast travel demand using techniques that are based on dissagregate models estimated from cross-sectional data. Their forecasts are usually single future time...
Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...
Using Interactive Simulation to Model Driver Behavior Under ATIS
This paper discusses the development and implementation of FASTCARS (Freeway and Arterial Street Traffic Conflict Arousal and Resolution Simulator), an interactive microcomputer based...
Trip Generation Analysis by Artificial Neural Networks
A new approach for conducting trip generation analysis based on the concepts of artificial neural networks is presented in this paper. First, a brief introduction to the concepts of artificial...
Design and Performance Requirements for Surface Facilities of a High Level Nuclear Waste Repository
This paper describes three important steps in the design process of repository surface facilities: (1) Establishing performance requirements and risk levels, (2) translating performance...
Interactive Buckling Analysis of Stiffened Shells Using Pregnant Sheel Elements
Two distinctive modes of failure dominate the failure of stiffened plates and shells, viz. the short-wave local mode and the long-wave overall mode. A new finite element technique which...
Containment Barrier System Performance Assessment Modeling
A mathematical model to predict the cumulative failure distribution for the containment barrier system (CBS) employed in a deep geologic disposal facility is presented as a function of...
Interactive Simulation for Modeling Dynamic Driver Behavior in Response to ATIS
It has been contended that in-laboratory experimentation with interactive microcomputer simulation can substitute for the lack of real-world applications and provide a useful approach...
Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...
Congestion Management?Opportunities for States and MPOs to Ensure the Efficiency of Their Highway Systems
The Clean Air Act Amendments of 1990 (CAAA) and the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) are effecting change in multimodal transportation decision making....
High Speed Rail: An Alternative Route to Preserve Quality of Life in the Northwest
The impacts of population growth threaten quality of life in the Pacific Northwest. Existing transportation systems cannot meet projected demand nor special needs of an aging society....
Potential Statewide Impacts of Florida's Proposed High Speed Rail System
This paper presents a summary of the findings from an analysis of the potential statewide impacts resulting from the construction and operation of a high speed intercity rail system in...
HSGT?Competitive or Complimentary to Air Travel
The capacity of existing airports to meet increased travel demand is limited. Utilization of high speed ground transportation as a complimentary mode originating from major hub airports...
Intercity Travel Demand Modeling and Forecasting for High Speed Rail Service in the Quebec-Ontario Corridor
This paper describes the application of intercity travel demand models and preparation of ridership and revenue forecasts for the Ontario/Quebec Rapid Train Task Force in 1990. The development...
Intercity Travel Demand Forecasting for the Windsor-Quebec City Corridor
Travel demand forecasts were required for the 600-mile-long Quebec City - Windsor Canada Corridor to test alternative rail systems including high speed rail. The approach involved application...
