Project: ITS infrastructure maintenance management
Principle investigator: Hualiang (Harry) Teng, 434-924-1461, hht4n@virginia.edu
External contact: Dwayne Cook, VDOT, Hampton Roads Smart Traffic Center
Project objective: To evaluate the existing ITS infrastructure maintenance management
Project
abstract: Maintaining ITS infrastructure is needed for the operation of ITS.
The goal and objectives of the system cannot be achieved if the ITS system doesn't
perform reliably due to the lack of maintenance. So far, ITS maintenance has been
focused on a macroscopic level where institutional issues have been discussed.
The maintenance issues such as the life cycle of system components and the system
as a whole haven't been touched upon.
In this study, the issue will be focused
on the life cycles and costs of system components and the whole system as a whole
will be investigated based on the maintenance records from Hampton Roads and Nova.
The maintenance policy in term of preventive maintenance interval will be evaluated
with comparison to the existing maintenance practices in these two traffic management
centers.
Tasks:
1.
Interview with the Hampton Roads and Nova STC to know their maintenance practices
2. Request maintenance records for field device, communications and in-house hardware
and software
3. Clean the maintenance records for research use
4. Determine
the life cycles for field device, communications, hardware and software
5.
Determine the costs for field device, communications, hardware and software
6. Determine the life cycles of the system that consists of the integration of
field device, communications, hardware and software
7. Determine the optimal
maintenance policy vs. cost
Milestones: Project will be completed in August 2004.
Student involvement: 1 GRA
Budget. $60,000
Relation to other research: Complement to previous work on ITS
Technology transfer: (workshops, classes, seminars, products): Presentations at conferences, publication of journal papers, final report
Potential benefits: Enhance maintenance for improving system performance
