How It Works
Working with Suppliers
Government agencies and owners of traffic signal systems are suppliers in our model, providing the access and permissions to use the traffic signal data generated from their owned and/or maintained intersection assets. Our Suppliers are at the beginning to make this technology possible.

Working with Partners
We work with other industry technology leaders to deliver our solution. Our Partners are an important component of our business, allowing for information to be shared from government agencies in the most efficient manner. Communications Data packets already communicating to the traffic signal controllers are picked up and delivered second-by-second, 24/7. We then deliver the data to our cloud-based computing center to feed into our algorithms and processes. These data are the building blocks of our technology. |
Data Flow from Traffic Signal to the Vehicle
|
Developing the Technology
Using a combination of data fusion and simulation, and a considerable amount of knowledge about traffic signal controller operations, we are able to predict how long the traffic signal controller will remain in red or green states. Information about the performance of the traffic signal controller, as well as the traffic demand both long- and short-term, is stored and analyzed.

Delivering the Product
Once the prediction is complete, we provide the Personal Signal Assistant data product about the signal controller following the SAE J2735 standard (Message Set Dictionary for Dedicated Short Range Communications). All signalized intersections in our system are provided via our Application Programming Interface (API). Getting Into the Vehicle How the information flows into the vehicle is determined by our customers and solution providers, but most often that is through an existing cellular signal. Either the vehicle, after-market device, or a smart phone provides this connection to the internet. Applications There are various applications of the Personal Signal Assistant. Read more in the next section. This is where the data gets translated to real-world solutions. |
