INTEROPERABILITY ISSUES ON MANAGED LANES FACILITIES

Often, a managed lanes facility is cross-cutting, not only from the multiple types of ongoing operations, but also because it can involve multiple agencies and vehicle user groups. These types of interactions all point to a level of interoperability heretofore unseen for most roadways. This study contained three steps - a literature review, a survey, and recommendations. The study found that while there were a number of pieces of useful information that resulted from the in-depth review of literature, there was one key concept that quickly became apparent - the notion of multiple levels of interoperability. The concept of multiple levels was somewhat opposite the initial thinking that interoperability was a global concept that existed across entire systems. Instead, the literature gave credibility to three levels of interoperability, namely: agency, facility, and equipment.
