This report presents an essential component of an airport's risk management data process: collecting and sharing operations and safety data. Such data helps airports monitor their performance and benchmark against the industry. To aid airports in this endeavor, this report identifies best practices and data sources for collecting such data. It also explains some of the challenges associated with the process and outlines a plan for a future national database.

A comprehensive review of the challenges of implementing managed lanes from the perspective of state DOTs is presented in this research report. The review covers much of the available literature (60 publications and over 700 media articles), a survey sent to 50 state DOTs, and six relevant case studies. With an often highly dubious public, there is quite a wide gap between the goals of DOTs' managed lanes and the public's assumptions. This research seeks to understand that gap and present best practices for overcoming the challenges facing tolling or pricing on managed lanes.
