TRB is seeking potential synthesis study topics as part of the upcoming activities of the Transit Cooperative Research Program (TCRP). Topics may be submitted at any time; however, the deadline for the upcoming submission cycle is March 18, 2016. All proposed new topics must be submitted online through the TRB Synthesis Topic Submittal website.

Synthesis reports are most valuable when they are focused on issues or problems common to many organizations. The primary users of the reports are the practitioners who work on those issues or problems using diverse approaches in their individual settings. Studies currently under way and all completed studies can also be accessed at the TRB Synthesis website. In addition to suggestions for new topics of study, please feel free to suggest updates of previously published syntheses. A brief statement of scope is required for each topic suggested.
