LESSONS LEARNED ON MAINTENANCE OF ITS DEPLOYMENTS

It is a fact: systems that are implemented but not properly maintained have more odds to fail. The same applies for deployments of Intelligent Transportation Systems (ITS). ITS being such a “new area within the transportation field requires a different approach for maintenance. ITS involves technologies that are not only constantly changing but also subject to extreme environmental conditions making maintenance unique and challenging. ITS maintenance is consuming more time and resources than originally expected and budgeted, by many transportation agencies; mainly due to little or no previous experience to use as a baseline. Even through ITS started to be deployed more than 20 years ago under various acronyms (i.e., IVHS), maintenance has generally been kept “in-house” and few lessons learned experiences have been documented. Maintenance is not glamorous! The purpose of this paper is to share with the ITS community an experience obtained from over 3 years of maintenance of an ITS deployment including both legacy systems and system expansions.
