Description: TPB staff, in consultation with the TPB Freight Subcommittee, identified a network of these freight-important roadways using a combination of data analysis and collective expertise. The resulting regional freight significant network is organized into three tiers.
• Tier 1 - roadways in this tier include state-designated truck routes, interstates, and other high volume roadways. These roads are the means by which most freight enters and leaves the Region and are typically used by pass-through trucks.
• Tier 2 - roadways in this tier allow trucks to permeate the Region and provide access to important freight generators and attractors. • Tier 3 - roadways in this tier provide last mile connectivity.
The regional freight significant network is a system of truck-allowed routes that are particularly important for goods movement.
Description: This dataset was created by the National Capital Region Transportation Planning Boardstaff, and includes all roads within the TPB Commuter Shed Region which collect a toll and/or is designated as either HOV/HOT.
