Skew Detection System Replacement of Vertical Lift Bridges (Phase I)

The prime objective of this research assignment is to provide a thorough literature search and evaluation of alternatives and a solution to the problem of replacing the legacy technology skew detection and monitoring system. One of the goals of the assignment is to select a system that does not require the Louisiana Department of Transportation and Development (DOTD) maintenance electricians to possess any additional expertise for its operation, maintenance, repair, or programming other than they possess today. An additional objective of the study is to identify a system or alternative systems that do not require sophisticated electronics but provide accurate and reliable information of span skew in the long term without excessive and frequent maintenance.
