Installation of connected vehicle roadside sensors in East Hawaii to help improve traffic signal timing and inform travelers.
The Hawaii Department of Transportation (HDOT) is installing Dedicated Short-Range Communications (DSRC)-enabled connected vehicle units on 16 state-owned traffic signals on Route 11 and Route 130 in East Hawaii.
These sensors will calculate travel times between signals by anonymously collecting data from Bluetooth-enabled devices in passing vehicles and broadcast the estimates to connected vehicles. The sensor data also feeds a dashboard that allows users to see current travel time and delay along the corridors and compare with typical conditions. HDOT and the County of Hawaii plan to use data from the units to optimize traffic signal timing. It is anticipated that the data available through the connected vehicle sensors will make corridor management more efficient by providing real-time information that was previously only available through timed drives through subject corridors. The installation of the connected vehicle units is HDOT’s first step in preparing Hawaii Island roads for connected autonomous vehicles.
Installation of the connected vehicle sensors on the 16 state-owned traffic signals in West Hawaii is anticipated to be complete in late November 2020. Total cost for the installations is estimated at $57,700.
