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.

TCRP Synthesis 145 gathers and analyzes many of the best current practices for preventing incidents and accidents on transit buses. Their study identifies the most common and most effective technologies including a number of collision avoidance technologies such as forward collision warning, emergency braking, lane departure warnings. and electronic stability control.

Transit Security Preparedness identifies practices transit agencies can use to improve their security to reduce their security risks, with a specific emphasis on practices related to new technologies. The report presents common themes in the approaches to security preparedness to aid transit agencies as they develop a process that fits their needs.
