• TMP updated iteratively throughout Design as TMP updated iteratively throughout Design as strategies are selected, TTC plans are developed, and Project changes occurj g– PI, TO, and PM strategies are explicitly identified in TMP– TCC&C strategies are not explicitly identified in TMP

TMP Developmenton RIDOT Projects
• Final Design Documentation
on RIDOT Projects• Final Design Documentation
– TMP submitted as part of each major Final Design b i i ( 30% 90% PS&E ADV & A d)submission (e.g., 30%, 90%, PS&E, ADV, & Award)
• One copy of TMP typically submitted to the following: Project Manager Construction Management Section – Project Manager - Construction Management Section
– Traffic Engineer - Transportation Management Center– FHWA Rhode Island Division Office (if Project oversight)
– Work zone safety and/or mobility-related analyses/reports should be provided as TMP attachments unless already i l d d i th Fi l D i t
