This paper presents pavement network level management using Micro PAVER with emphasis on pavement condition prediction modeling and annual and long range work planning....
An Overview of Markovian Models for Bridge Management Systems
The typical infrastructure maintenance decision-making environment involves multiples objectives, uncertainty, and dynamics of the most commonly used infrastructure models, which captures...
Deterioration Models for Highway Bridges
Infrastructure management, especially in case of highway bridges, need a realistic and effective deterioration model in order to provide information on the present and future condition...
The Finnish Bridge Management System
A computer-based Bridge Management system, BMS, was designed in Finland by the Finish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Identifying a New Role of the Future Planner
It has been amply demonstrated over the last three decades that public planning is subject to great uncertainties, both in dealing with new technologies as well as in dealing with fuzzy...
Projecting Land Use/Transportation Interactions
The inherent uncertainty in forecasting the interaction between transportation capacity and induced development has resulted in insufficient analysis of this dynamic in the transportation...
Planning for Electronic Toll Collection
With major plans for toll plaza expansion to accommodate growing patronage, the Florida Turnpike had to consider options for reducing future right-of-way acquisition and still provide...
A Short-Term Demand Forecasting Model from Real-Time Traffic Data
Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions...
Implications of Uncertainty in Transportation Control Measures: A Case Study of the Los Angeles Truck Management Program
The Los Angeles Department of Transportation has proposed a peak period travel restriction aimed at heavy-duty trucks on all Los Angeles streets. The ordinance is designed to reduce the...
Use of Fuzzy Theory for Dealing with Uncertainty: Evaluating Alternatives Under Uncertainty
A method to deal with uncertainty which is associated with vagueness and ambiguity is presented. Fuzzy sets are introduced to account for vagueness in expression and fuzzy measure is introduced...
