|Project Description:||This project is to identify the necessary interfaces for two-way communication of traffic signal information between the traffic signal controller and a mobile device, provide the concept of operations for the use of the interfaces, and develop prototypes of the interfaces using signal controllers from two different manufacturers. The interfaces and prototypes shall be for use by the connected vehicle applications that require signal phase and timing (SPaT) and its related messages.|

|Start Date:||January 28, 2011|
|End Date:||June 30, 2013|
The key project objectives are listed below:
(1) Develop a two-way interface specification between two signal controller brands and Roadside Equipment (RSE) that will send signal phase and timing data from the traffic signal controller to mobile devices and receive Basic Safety Messages and Requests for Service from mobile devices using the National Transportation Control Interface Protocol (NTCIP) 1202 and the Society of Automotive Engineers (SAE) J2735 standards.
(2) Test this interface at Turner-Fairbank Highway Research Center in the Transportation Operations Laboratory: Connected Vehicle Highway Testbed.
(3) Procure, configure, and deploy 50 signal phase and timing (SPaT) interface devices at Safety Pilot and other affiliated testbeds.
|Background Information:||This project is part of Track 3, Enabling Technologies, for the Vehicle-to-Infrastructure (V2I) program.|
|Test Methodology:||Contracted research|
|Fieldtest:||Testing will be conducted onsite at Turner-Fairbank Highway Research Center.|
|Expected Benefits:||This project will enable all of the benefits of the connected vehicle highway program applications to be realized.|
|Deliverables:||Name: Configure and deploy one model (Econolite) of an intelligent traffic signal controller and signal phase and timing (SPaT) interface devices at six intersections on Fuller Road as part of Safety Pilot. This also includes the latest version 3 of 5.9 GHz Dedicated Short Range Communications equipment.|
Product Type(s): Hardware, Software, Support
Description: Procure, configure, and provide technical (onsite and offsite) support to successfully deploy signal phase and timing (SPaT) interface devices at six intersections at the Safety Pilot Model Deployment in Ann Arbor, Michigan.
