A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...
Finite Element Analysis and Design of Bridges with Applicatrons of ICAD
This paper describes applications of client-server models, interprocess communications (IPC), and concepts of intelligent CAD (ICAD) to the interactive design and analysis of highway bridge...
Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...
Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
Safety of Passengers on Railway Platforms?Using Various Computers
Recently, it has become very important to take measures to improve platform safety in Japan. Many passengers use railway platforms all day long (from the first train to the last train)....
The Automation of Freeway Ramp Junctions Analysis
Congestion on urban freeways has been steadily increasing. In contrast, capacity expansion, by means of constructing new roadways, has not kept pace with the growth in demand. The primary...
A New Approach for Road Network and Bridge Planning
Road networks usually include a large number of bridges and tunnels. The locations of these bridges and tunnels are decided by the road planner during the design of the road alignment...
Application of Computer Simulation in the Research of Rail Structure Vibration Reduction
The wheel/rail system is described here as a random vibration system, and the state variables are expressed with quadratic evaluation function. The passive control problem of the random...
Emergency Response Team Siting for HLRW Movements
The shipment of high-level radioactive waste to treatment plants, storage facilities, and repositories is an activity of major national concern. This paper presents a multi-objective methodology...
Multiple Objectives, Uncertainty and Routing Decisions for Hazardous Materials Shipments
Explicit consideration of multiple objectives and uncertainty is important in hazardous materials transportation, particularly in regulating routes or making routing decisions. Application...
Algorithms for Efficient Real-time Traffic Assignment
Fast algorithms are essential to accomplish real-time traffic assignment for optimal routing or traffic prediction under ATMS/ATIS. User-equilibrium and system-optimal traffic assignment...
A Real-Time Expert System for Freeway Incident Management in Orange County, California
This paper discusses the development of a prototype, multi-user, networked, real-time knowledge-based expert system (KBES) to provide decision support to California Department of Transportation...
A Spatial Decision Support System for Vehicle Routing
This paper describes the design, development, and implementation of a computer aided system for planning efficient network maintenance routes. The system has been used to design snow and...
GIS Applications in Urban Roadway Management Systems
The urban roadway network is a major component of any municipal infrastructure system. Effective management with systems methodology can greatly increase the service life of these facilities...
A Dynamic Mapping Application for an ATIS
A dynamic mapping application for an Advanced Traveler Information System (ATIS) is described. The application requires tracking maintenance vehicles so that paths can be displayed indicating...
Benefit-Cost Analysis for Optimal Budget Allocation to Bridges
The funding available for bridge improvements in the United States has been insufficient for many years. The limited budgets granted have generally been allocated based on Sufficiency...
NCHRP Project 12-28(2)A Bridge Management System Software
This paper describes the various features of the bridge management system being developed by NET Corporation as part of a project funded by the National Cooperative Highway Research Program...
Bridge Management System Implementation at CALTRANS
Development of a new generation of Bridge Management System (BMS) capabilities has been a high priority for CALTRANS for the past four years. Although the Department has had a bridge inventory...
The California Smart Traveler 1993 Status Report
