Applications and Use Cases
|
Infotainment
The easiest application is returning the Personal Signal Assistant data to the driver. This information can provide the driver with information such as how much time is remaining in red, providing the driver with an understanding of the expected delay. This information also reduces "lost time" - the amount of green time that isn't used because a driver is not paying attention - for the Supplier transportation network. |

Engine Management
Applications by Automotive or Truck OEMs and Tier 1 providers may include direct integration with the engine Start-Stop technology, allowing the vehicle to be smarter about the location. Is the vehicle at a stop sign or a traffic signal? And if at a traffic signal, how much time is remaining in red? Personal Signal Assistant data can answer that question immediately. |

Green Light Optimal Speed Advisory (GLOSA)
This application provides the driver information about the suggested speed to avoid stopping at the upcoming traffic signal. How is this information known? The Personal Signal Assistant provides information on the remaining time for the vehicle's approaching red, and using the vehicle or an after-market device for velocity and location, the driver is provided a suggested speed to avoid stopping. |

Powertrain Efficiency
Hybrid vehicles, including the new 48V systems, can benefit from Personal Signal Assistant data by maximizing the use of the vehicle’s regenerative braking capabilities to improve the overall efficiency. These kinds of applications do not require driver interaction and in fact may never be known to the driver, as only the vehicle’s main computer and powertrain system receives and utilizes the information. |

Routing Services
Last legs of any trip can benefit from knowing information on how long the traffic signal will be remaining green or red for the route. Or what is the typical amount of time of green or red (delay) for each of the movements. Routing services can now use better data to improve the routes and decrease the driver's time.

Transit
Buses and light rail vehicles are also users of transportation networks with complex and well connected traffic control systems. Several of the above applications also apply to transit vehicles, which can improve customer service and ridership experiences by optimizing stop or wait times, and always arriving on green.

Pedestrian & Bicycle Users
Non-motorized modes such as pedestrians and bicycles can benefit from Personal Signal Assistant by having a precise prediction of when a specific Walk or Bike signal will turn green. Most importantly, it provides them with positive feedback in locations with phase actuations (e.g., push buttons, video, inductive loops, etc.) clearly letting them know that their presence has been detected by the control system.

Delivery Robots
Delivery robots traveling on sidewalks need to know the status of the Walk signal in order to safely cross the street. Furthermore, they need to have the ability to virtually place a pedestrian pushbutton. Personal Signal Assistant offers the perfect solution for this problem.
