This page provides plots of vehicle length or "freight" data. A primary purpose of collecting and using vehicle length data is to distinguish freight vehicle traffic from non-freight vehicle traffic. Thus while the data used for the plots on this page is technically called vehicle-length data, we have named this page as the "freight" page.

Data Availability Note: There have been periodic outages of the freight data feed in Fall 2017. In particular, there was an extended outage from Sep 30 - Oct 27.

Two plots are available on the page - the Standard view and Comparison view. These plots were designed to answer the following two tasks a user may want to accomplish.

Task 1: What percent of traffic at a location is freight vs. non-freight? (Standard view)

Task 2: How has the amount / percent of freight traffic at a location changed over time? (Comparison view)

A User Manual for the freight page as well as other related documents are available at the bottom of this page.
