This report reviews current practice in coordinating transportation system management (TSM) and land use management (LUM), with emphasis on the ""operating environment"" level as opposed to individual projects. A review of relevant literature was supplemented with interviews with those involved in this field. It is hoped that this synthesis will help identify the research needed for improvements in TSM programs and practices and focus more attention on value of coordinating TSM and LUM.  The report for this topic can be  purchased at https://www.trb.org/news/blurb_detail.asp?id=3464
