Discovery-T2X Systems Platform – FAQ

  1. What is Discovery-T2X?
    • Discovery-T2X is STAR Systems International’s multi-communication platform consisting of an On-Board Unit (OBU) and Roadside Unit (RSU) designed to operate in both current RFID based tolling systems and emerging V2X (vehicle-to-everything) environments.

 

  1. What does “T2X” stand for?
    • T2X stands for “transponder-to-everything”, reflecting the platform’s ability to extend the functionality of traditional toll tags to integrate into broader connected vehicle ecosystems using both traditional RFID and developing C-V2X technologies.

 

  1. What value does Discovery-T2X deliver?
    • Discovery-T2X exists to bridge legacy tolling infrastructure with emerging V2X technologies, enabling a smooth transition without costly system overhauls. It empowers toll agencies and fleet managers to modernize at their own pace while unlocking new capabilities in connected mobility, tolling, and road safety.

 

  1. Who is Discovery-T2X designed for?
    • Discovery-T2X is designed for toll agencies, fleet managers, transportation authorities, and operators seeking a practical, phased approach to modernization without abandoning existing systems.

 

  1. Does Discovery-T2X work with existing tolling systems?
    • The OBU and RSU are both fully compatible with the current multi-protocol tolling infrastructure. In addition to compatibility with the current C-V2X stack, Discovery-T2X implements the ISO 18000-63 Type C (6C) RFID protocol.

 

  1. Does Discovery-T2X require new roadside infrastructure?
    • Discovery-T2X is designed to integrate with existing infrastructure, minimizing the need for immediate large-scale investments.

 

  1. How is Discovery-T2X deployed?
    • The OBU is installed in vehicles like traditional toll tags, while RSUs are deployed on the roadside as needed. The system integrates with existing back-office platforms as well as other software platforms.

 

  1. Will agencies need to replace devices later for V2X?
    • Discovery-T2X OBUs and RSUs are designed to support both current and future systems, eliminating the need for future hardware replacement.

 

  1. What communication technologies are included in the OBU?
    • UHF for tolling compatibility
    • C-V2X using SAE J3217 for future connected systems
    • Wi-Fi and Bluetooth for mobile and backend connectivity
    • GPS for geofencing and location-based applications
    • CAN Bus interface for vehicle data access

 

  1. What types of applications does Discovery-T2X support?
    • Traditional toll collection
    • Fleet and commercial vehicle management
    • Distance-based road usage charging (RUC)
    • Geofencing for tolling
    • Traffic and congestion management
    • Vehicle data analytics
    • Safety-related messages (e.g., wrong-way driving and accident detection)

 

  1. Can Discovery-T2X access vehicle data?
    • Through its CAN Bus interface, the OBU can access real-time vehicle data to support advanced applications and analytics.

 

  1. Does Discovery-T2X support vehicle occupancy detection?
    • The OBU can extract vehicle data and utilize built-in vehicle sensors to determine how many occupants are in the vehicle.

 

  1. How does Discovery-T2X reduce risk?
    • It enables agencies to continue operating current systems while gradually introducing new capabilities, avoiding large upfront investments and uncertain timelines.
