Research/Project Description

Next Generation of Smart Traffic Signals:

Assess whether a self-adaptive traffic control system can be an effective approach for large scale adoption of adaptive traffic control systems.

Develop and test a next generation traffic adaptive control system that is self-learning; eliminating the need for traffic signal operators to collect the data needed to set control parameters.

Simulation analysis and limited field testing will be conducted; VII-enabled enhancements will be developed and tested

Research/Project Description

Arizona E-VII Program Summary

Maricopa County REACT arterial incident response trucks and Arizona DOT ALERT freeway service patrol trucks will be used for the proof-of-concept test and demonstrations. Prototype applications will be developed using VII technologies for traffic signal preemption and priority, ramp meter preemption (queue flushing), and mobile incident warning. In addition to using the VII technology for preempting the signal for the incident responder, the VII RSE will also be used to broadcast warning messages to other VII-enabled vehicles that an emergency response vehicle is approaching - vastly improving the safety of an intersection during preemption. In the mobile incident warning prototype application, the on-board unit of the incident response vehicle will function as an RSE to warn on-coming VII-enabled vehicles of the hazard once the incident responder arrives on-site. In addition, the incident response vehicle may upload incident details (number of lanes blocked, location, special response needs, etc.) to the VII network for dissemination to other incident responders through other RSEs further away from the incident site.
