TR I is for corridors that are essential to freight movement in the District; TR II is for the roads that carry significant traffic but are less important for heavy truck traffic than TR I; and TR III is for the core high-security area as demarcated by National Capital Planning Commission   Specific recommendations include preferred truck routes, a metering system for use of the curb space and "peak pricing" and/or restricted rush hour loading and unloading.   The full draft is available under on the DDOT Web page, ddot.dc.gov, under Transportation Studies.
