Posted on Apr 1, 2020 in Highways News, Main, News

HONOLULU – The Hawaii Department of Transportation (HDOT) is sharing traffic volume data for major state routes on the HDOT website. The data will be updated weekly on Mondays and is available at:

HDOT is making this data available during the period of Governor Ige’s Stay-at-Home order, which became effective Statewide on March 25 and is in place through April 30, to verify the capabilities of major state routes to accommodate extended lane closure hours and to provide general data on compliance with the order.

After the Stay-at-Home order period passes, HDOT will continue to update the data as an economic indicator for the State.

The percentage change in the traffic volume data is calculated from the 2019 Average Annual Daily Traffic counts taken by permanent traffic counting stations HDOT maintains Statewide.

This data accompanies other offerings on the HDOT website such as the Highways Program Status Map (linked here) and the Lane Closure Map (linked here). Please note that the Highways Program Status Map that is normally updated on the first working day of the month will be temporarily delayed, but still contains the latest available data as of March 2 on current and future HDOT projects, pavement and bridge conditions, and locations and major contributing factors of fatal crashes.
