Deighton Participates in Sydney Harbour Bridge Project
by Jeff Zavitski, Deighton

Deighton is very excited to be involved in a high profile demonstration project with the Australian Road Research Board (ARRB) working with the Roads and Traffic Authority (RTA) of New South Wales Australia to manage the painting of the world famous Sydney Harbour Bridge.

Officially opened in 1932, after 6 years of construction, the bridge contains steel surface areas of approximately 60 football fields that require continuous maintenance, painting and renewal. Deighton and ARRB are configuring dTIMS CT to investigate the development of a maintenance, rehabilitation and renewal program for a "paint condition" system within dTIMS CT.

RTA would like to be able to determine funding levels based on percentage limits in each condition category of Excellent, Good, Fair and Poor. Deighton is configuring the analysis so RTA can determine the distribution of condition in each category for a given funding level, or, RTA can determine the required funding level to achieve a required distribution of condition.  All of us at Deighton are excited to be a part of this project and look forward to the projects results.

New Initiatives at Louisiana Department of Transportation (LADOTD)
by Richard Fox-Ivey, Deighton

The Louisiana Department of Transportation (LADOTD) has been using dTIMS CT as a decision support tool for pavement management since 1991. Over the years a combination of software enhancements and departmental ingenuity has ensured that the software and its setup have continued to effectively serve the pavement management needs of LADOTD.

The DOTD recently decided to take a big step forward in the management of their network and their use of dTIMS CT to increase the accuracy of pavement condition modeling, adopt a whole host of new technologies and to perform cross asset analysis between pavement management and safety management. Some of their exciting new initiatives include:

  • Site-specific Performance Curves: Enhancements to the Department's existing dTIMS CT implementation to make use of site specific performance curve research completed at the University of Louisiana at Lafayette. The goal of this effort is to improve the accuracy of deterioration modeling and therefore enable more precise programming of the annual paving program
  • Implementation of Deighton's Management Dashboard (md) software: to allow for improved data visualization, including enhanced graphing and mapping of PMS data and data sharing through MDs zero-footprint, browser-based, functionality
  • Enabling Use and Distribution of GPR Data in dTIMS CT: to improve modeling in dTIMS CT through the inclusion of structural data (estimated from GPR) as well as to provide a mechanism for the Department to easily distribute and display its newly-collected GPR data (through the new Management Dashboard)
  • Implementation of Deighton's Work Flow software: to allow for the documentation, storage and automation of its complex pavement management system business processes
  • Incorporation of Roadway Safety in PMS Modeling: the configuration of a safety-based analysis within the dTIMS CT framework to allow for modeling of safety hot spots along the network, safety improvement strategy recommendation, improvement budgeting, and trade-off analysis
Arkansas Working Towards Total Infrastucture Management Using dTIMS CT
by Arif Rafiq, Deighton

The Arkansas State Highway and Transportation Department (AHTD) recently upgraded their current desktop pavement management application to dTIMS CT SQL, an enterprise tier asset management software solution.

Prior to the software upgrade, AHTD was using an older Deighton product known as dROAD to store roadway inventory and condition data. With the new dTIMS CT SQL solution, AHTD staff are now empowered with multiple concurrent user access to not only their existing roadway inventory and condition information, but also to the powerful dTIMS CT SQL analytics. Among other things, AHTD staff will now be able to configure and execute a network level pavement analysis based upon AHTD defined budget scenarios, forming the basis for typical multi-year analyses.

While the new solution will be currently implemented exclusively for roadway and pavement data, AHTD intends to implement the management of additional assets such as structures, signs and other roadway assets all within dTIMS CT SQL. Upon the implementation of additional assets, AHTD staff will be able to perform multi-year analyses based on multiple sets of assets using global, or asset-class-dependant, budget scenarios.

By choosing to use dTIMS CT SQL as their asset management software platform, AHTD will not need to purchase additional software in order to implement additional assets into their system. AHTD now has all of the software tools necessary to continue on their journey towards Total Infrastructure Management.

Transportation Research Board (TRB) 90th Annual Meeting
by Arif Rafiq, Deighton

The Transportation Research Board (TRB) 90th Annual Meeting will be held on January 23-26 in Washington, D.C., at the Marriott Wardman Park Hotel. In recent years, the information-packed program has annually attracted more than 10,000 transportation professionals from around the world to Washington, D.C. Deighton will be exhibiting so be sure and visit us at booth #1215!
