Dutch iVRI Testing & Acceptance Application

Enabling Real-Time, Location-Aware In-Vehicle Road Intelligence Across the Netherlands

Overview

The Dutch iVRI (intelligent Vehicle-Roadside Interface) Testing & Acceptance Application is a specialized software platform designed to support the development, testing, and validation of connected vehicle (CV) systems within the Netherlands' advanced intelligent transportation infrastructure.

Built on the national iVRI framework, this application delivers real-time, context-aware road and traffic information to vehicles via secure, standardized V2X (Vehicle-to-Everything) communication channels. It serves as a critical tool for verifying interoperability, performance, and reliability of vehicle-to-infrastructure (V2I) interactions across diverse traffic environments.

Core Functionalities

The application provides timely, high-precision data to enhance situational awareness, safety, and traffic efficiency:

🛣️ Dynamic Speed Management

• Continuous monitoring and broadcast of static and variable speed limits along the route.
• Real-time updates in response to traffic conditions, weather, or roadwork.

🚦 Adaptive Lane & Overtaking Intelligence

• Real-time visibility into lane configurations, including temporary lane closures and reassignments.
• Alerts on overtaking restrictions, such as no-passing zones or dynamic lane-use management.

⚠️ Traffic Signal Integration & Prediction

• Access to traffic signal status and phase information (e.g., green, yellow, red).
• Phase prediction algorithms to enable smoother, more efficient signal passage, reducing stops and emissions.

🚨 Priority Request Functionality

The application supports priority registration at iVRI-equipped intersections and road sections, enabling enhanced mobility for critical vehicle types:

Supported Vehicle Profiles:

• Emergency Vehicles (NHD – National Highways Department)
  Prioritized clearance at signalized intersections, dynamic speed adaptation, and lane management coordination.

• Public Transport Buses (PTV)
  Signal preemption and green wave optimization to improve schedule adherence and passenger experience.

• Commercial Freight Vehicles
  Preferred routing, priority access at bottlenecks, and coordination for logistics efficiency.

Note: Priority requests are processed via secure, authenticated messaging through the national iVRI network, with access rights managed per vehicle profile and authorization level.

🧪 Use Case: Testing & Validation

This application is a cornerstone of the Dutch national testing and acceptance framework for connected and automated mobility (CAM), enabling:

• End-to-end testing of V2X message exchange (e.g., SPaT – Signal Phase and Timing, MAP – Map Data).
• Validation of timing accuracy, message reliability, and system responsiveness under real-world conditions.
• Compliance verification with Dutch iVRI standards, ISO 15638, and ETSI ITS-G5/DSRC & C-V2X protocols.

✅ Benefits

• Enhanced safety through proactive hazard and restriction awareness.
• Improved traffic flow via intelligent signal coordination and lane management.
• Standardized testing for national and international vehicle manufacturers and infrastructure providers.
• Scalable deployment across the Dutch road network, supporting future mobility innovation.

📌 Future Roadmap

• Integration with national traffic management centers (TMCs) for centralized monitoring.
• Expansion to support autonomous vehicle (AV) testbeds and platooning trials.
• Enhanced data analytics and reporting for infrastructure operators and policymakers.

Developed in collaboration with the Dutch Ministry of Infrastructure and Water Management, ProRail, Rijkswaterstaat, and the Dutch iVRI Consortium.
