V2X Initiatives for Road Safety (VIROS)

16 Feb 2023 3:07 PM

TheV2X Initiatives for Road Safety (VIROS) Project is pioneer in V2X Research in the Philippines. The pilot tests serve as benchmarks for future explorations, developments, and applications of V2X world-wide. The proposed intelligent traffic controller also serves as valuable contribution towards modernizing traffic infrastructure in the country.



VIROS Project proposed to design and develop an intelligent traffic controller unit with wireless communication capability. The intelligent traffic controller gathers and assesses traffic conditions, does data-driven traffic control, and communicates these traffic conditions to road-users. For its pilot implementation, the application of the technology is intended to aid traffic management and improve overall road safety.

Using AI-based methods in computer vision, the intelligent traffic controller can analyze traffic statistics such as vehicle recognition and vehicle flow rate, to assess the traffic condition and direct traffic. The traffic information is then communicated by these controllers wirelessly to vehicle drivers, pedestrians, and other-road users through Vehicle-to-Everything (V2X) The application of the technology is intended to improve road-safety and driver decision making while traversing the roads.



VIROS Project has the following components:

  1. Intelligent Traffic Controller Prototype
    • Design and development of trailer-mounted intelligent traffic controller (Fig. 1)
    • Gathering, analysis, and transmission of traffic statistics
    • Data-driven traffic control sequence
    • Variable Message Signboard for visual cues and messages
    • Pedestrian prioritization

    • Characterization and evaluation of commercially available V2X protocols and devices in the market
    • System integration with intelligent traffic controllers (Fig. 2)

Smart City Administrators and Traffic Management Agencies (MMDA, LTO, DoTC, etc.) can greatly benefit in this project, specifically in modernizing traffic infrastructure in the Philippines. This in turn, will also benefit road users in improving traffic conditions and road safety.

Lastly, VIROS Project can also serve as benchmark for future V2X related studies locally and internationally.

  • Fellow Local and International V2X Research Agencies
  • Road User (Motorists, Pedestrians, Emergency Response Units)
  • Legislators/Policy Makers for traffic regulations and wireless communications



DOST-ASTI signed a Memorandum of Agreement (MOA) with The University of the Philippine – Department of Computer Science (UP-DCS) as co-implementing agencies of VIROS Project.
