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...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
This paper presents an integrated database structure for the storage and retrieval of information during the planning, design, manufacturing and construction of a structural precast concrete...
Modeling Facility Engineering Processes & Data Using the P-C Approach
A facility engineering process typically involves participants from different disciplines, several life-cycle phases, and many computer applications. In this paper, we propose the Primitive-Composite...
An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...
Adaptive, Multi-Resolution Modeling of Construction Plans
The process of developing a construction plan is complex, taking many considerations and constraints into account. In contrast, the CPM paradigm of planning allows only the results of...
An Effective Estimate of the Percentage Completion of Construction Projects and Concomitant Progress Payments
This paper will discuss the methods of assistance to contractors in visualizing the effects of variations in the quantities of their work and how to obtain such information effectively....
Filing of Construction Photos Linked with Database
In order to raise the added value of construction information, a filing system of construction pictures is built up and is used theoretically linked with a database. Here, conditions set...
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...
Design Information Hierarchy for Construction Method Selection Process
