The Hawaii DOT (HDOT) recently announced the availability of connected vehicle technology within the Ala Moana Boulevard / Nimitz Highway corridor.

The connected vehicle technology can provide alerts and other information about the corridor to motorists, bicyclists, and pedestrians through a free application, according to HDOT.

HDOT requested proposals for a connected traffic control system on the Ala Moana Boulevard / Nimitz Highway corridor in late 2019 as part of a research project with the University of Hawaii. The goal of the research project is to determine the capabilities of the latest connected traffic control systems to efficiently and safely manage multiple modes of transportation. Installation of the system components was completed in April.

“The Vehicle to Everything (V2E) solution selected for the Nimitz pilot is a huge advancement in management of our corridors,” HDOT Deputy Director for Highways Ed Sniffen said in a statement. “We’re now able to communicate with the controllers using 4G cellular modems and utilize adaptive signal control to respond to situations causing congestion along the route. It’s a total game changer.”

Roughly 720 detection zones (cameras and pucks) and 34 roadside units were installed through the Nimitz V2E Pilot. The detection zones measure traffic through a combination of video detection, which is not recorded, and magnetometer. Data from the detection zones tells the controllers what types of vehicles are moving down the corridor and how efficiently they are moving. Communications between the detection zones, roadside units/controllers and the Advanced Traffic Management System (ATMS) is facilitated through secure CV2X (cellular) and DSRC (Digital Short Range Communications) signals.

Motorists, bicyclists, and pedestrians traveling through these intersections can receive safety information such as audible alerts when there are potential conflicts through a free app called TravelSafely.
