A multi-layer perceptron back propagation neural network based methodology has been developed to process and analyze moire fringes obtained with an automated highway pavement inspection...
An Application of MCDM to Product-Based Pavement Management
The Finish National Roads Administration is currently developing it's organization to be more object-oriented and profit-making. This renewal implies to so called product-approach. In...
Uncertainty in Economic Evaluation of Upgrading Gravel Surface Roads
Many highway links in the world are still gravel surfaced. As traffic volumes increase, the demand for upgrading these surface also increases. The challenge to highway infrastructure management...
Combining Symbolic and Algorithmic Methods for Capital Budgeting in Highway Rehabilitation
The Pavement Rehabilitation Analysis and Design Mentor (PARADIGM) is a prototype, microcomputer -based, integrated set of interacting expert systems and algorithmic models. This paper...
Transient Performance Model of Asphalt Pavement Deterioration and its Application to Repair Management
The Japanese Ministry of construction has conducted surveys of the pavement surface condition of national highways. This paper describes the evaluation of the performance of asphalt pavement...
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...
Treating Uncertainty in the Design of Horizontal Curves
A model based on expected total cost minimization approach is developed for determining optimal horizontal curvature for highway sections. Expected total cost is defined as the sum of...
Implementation of the Indiana Bridge Management System
Management of a bridge system involves a complex decision-making process. A comprehensive bridge management system provides a set of tools that aid this process by selecting improvement...
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...
Maglev Utilization of Interstate Highway and Railroad Rights-of-Way
Government officials and transportation industry experts have proposed that existing highway and railroad rights-of-way could be utilized effectively to host maglev guideway route alignments....
High Speed Rail Loading Scenario and Dynamic Tuning of Track
Similarities and differences exist between conventional and high speed rail (HSR) infrastructure design. The differences stem from the dynamic nature of the HSR loading scenario and the...
Small-Government GIS
Geographic information systems, or GISs, have shown great potential for use as a tool by public engineers working on the state and municipal level, but the time and money required to put...
Upper Watershed Management and Sedimentation in Mugu Lagoon, Ventura County, California
Mugu Lagoon is one of the last remaining, natural salt marsh systems in southern California. In the last 90 years, sedimentation in the lagoon has increased from a geologic rate of 0.17...
Bulgarian Coastal Management
This paper responds to the call of the 1992 United Nations Conference on Environment and Development for sustainable and economically-sound development and use of the world's natural resources....
IVHS Strategic Planning for Washington State
Implementation of IVHS technologies must be based on a strategic planning approach. The strategic plan must consider regional and statewide needs and should prompt integration of IVHS...
Before-After Evaluation of FTMS Effectiveness
This paper demonstrated the possibilities for conducting before-after evaluation of a new freeway traffic management system (FTMS) using only data from the inductive loop detectors. Using...
Estimation of Queue Lengths in Urban Road Networks
In this paper we present a new scheme for the surveillance of traffic state on a link of an urban road network. It is shown that measurements of traffic counts and speed values from a...
Travel Time Data Fusion in Advance
The ADVANCE project in the Chicago metropolitan area is one of several ATIS operational tests currently underway in the USA and abroad. Fusion of equipped vehicle (probes) travel time...
Filtering and Prediction on Freeways Using Markov Models
A Markov compartment model of freeway traffic flow is presented and used to derive a Kalman Filter which tracks a freeway section's density, broken down by destination. The filter is then...
