A statistical analysis of fuel reduction and schedule fidelity achieved through automated corridor signal negotiation.
Commercial freight fleets lose millions of gallons of diesel annually decelerating and idling at urban and arterial traffic intersections. Frequent stop-and-go cycles accelerate brake wear, increase greenhouse gas emissions, and degrade schedule predictability.
V2Fleet standardizes SAE J2735 Signal Request Message (SRM) and Signal Status Message (SSM) transactions. As a fleet vehicle approaches an equipped signalized intersection, its onboard telematics unit estimates arrival time based on weight, grade, and traffic density, requesting a green extension or early green window. ``` +---------------------+ PC5 / SRM +---------------------+ | Heavy Freight Truck | --------------------------------> | Traffic Signal RSU | | ETA & Weight Vector | <-------------------------------- | Green Window Grant | +---------------------+ PC5 / SSM +---------------------+ ```
Across a 45-kilometer freight arterial corridor with 32 signalized intersections, commercial trucks equipped with V2Fleet demonstrated a 19% reduction in travel time, 14% lower fuel consumption, and an 80% decrease in full-stop events.
