Implementation of a District Level Highway Routine Maintenance Needs Assessment Program
A routine highway maintenance needs assessment program allows a transportation agency to establish a maintenance work program consistent with the objectives of a pavement maintenance management...
TRACS: A Tool for Track Infrastructure Management
TRACS (Total Right-of-way Analysis and Costing system) combines engineering models with life-cycle costing techniques to estimate track maintenance and renewal costs as a function of track...
The State of the Art of Bridge Management Systems
The development of Bridge Management Systems, and Pontis in particular, requires states to change many of their traditional inspection and record-keeping procedures. If these are changed,...

This paper describes a comprehensive Pavement Management System (PMS implemented at 24 airports in the kingdom of Saudi Arabia. The PMS development and implementation was completed in...
Highway Maintenance Data Collection: State of the Art
Existing procedures for recording highway maintenance and field inventory data re laborious and time consuming because the information is entered twice - first on standard paper forms...
Traffic Signal Management Utilizing Fiber Optic Cable
Fiber optic cable technology has progressed from the pioneer stage and is becoming a widely accepted method of data transmission. Utilization for traffic signal systems, however, is not...
Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
Large Truck Impacts on the Highway Infrastructure: The Bridge Dimension
Recent U.S. studies have explored the productivity gains of longer combination vehicles (LCV's) and their impacts on highway infrastructure. The area least explored is LCV operations and...
Tie Model: A Crosstie Replacement Planning and Costing Model
The Tie Model described in this paper is a maintenance planning and life-cycle costing model for wood crossties. The model includes a number of different failure modules to predict crosstie...
An Integrated System for Pavement Management
This paper describes the process of developing an integrated computerized pavement management system (PMS) for the New York State Thruway Authority. The process evolves around the integration...
Managing a Bridge Program for Scour
Recent events have focused national attention on the need for States to implement a managed program to determine the scour vulnerability of each of its bridges. Since 85% of all bridges...
Maintenance Management of Power Transmission Lines
An adb-based maintenance management system, KUHA, was developed in Finland to enable more efficient maintenance of power transmission lines. The system is used for strategic planning in...
Planning Maintenance and Rehabilitation Activities for Local Railroads
This paper presents a structured approach for planning annual and long range (multi-layer) maintenance and rehabilitation (M&R) activities for local railroads. A method is presented...
Addressing Uncertainties in Flexible Pavement Maintenance Decisions at Project Level Using Bayesian Influence Diagrams
Bayesian influence diagrams are directed acyclic graphs used as a network representation for making decisions under uncertainty. These representation facilitate the assessment of coherent...
Inspection and M&R Decisions for Infrastructure
This paper reviews different possible mathematical formulations for a joint inspection and M&R decision-making model, having various levels of restriction and computational complexity....
Pavement Network Level Management Using Micro PAVER
This paper presents pavement network level management using Micro PAVER with emphasis on pavement condition prediction modeling and annual and long range work planning....
Mitigation of Excessive Wastewater Infiltration/Inflow Effects for US Army Installations
Wastewater collection system on military installations require periodic maintenance and repair, and occasionally upgrading. Deterioration of wastewater systems enables the entry of extraneous...
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...
