Turkey Accelerates Deployment of Connected and Autonomous Vehicle Technologies
The Ministry of Transport and Infrastructure has advanced Turkey’s connected and autonomous vehicle (CAV) agenda by planning a 247-kilometer smart transport corridor around Ankara. The project builds on learnings from the country’s first K-AUS (Cooperative Smart Transport Systems) test corridor between Hasdal and Istanbul Airport and scales the technology suite—roadside units, control centers and vehicle-to-everything communications—across motorway, regional and intercity segments.
What the 247 km Ankara Corridor Will Cover
The corridor splits into three precise segments: 166 km of Ankara Ring Motorway, 22 km of Gölbaşı–Oğulbey and 59 km of Polatlı. Together they form an integrated testbed for CAV features at intercity speeds and mixed traffic conditions. Deployments will include 5G-enabled roadside units, synchronized traffic sensors and centralized operations for real‑time monitoring and interventions.
How the Project Leverages Istanbul Test Results
Data and operational lessons from the Hasdal–Istanbul Airport pilot inform the Ankara rollout. That pilot validated 5G latency requirements for vehicle-to-infrastructure (V2I) messaging, defined edge-compute placement for low-latency control loops, and refined protocols for secure data exchange between vehicles and central management systems. Ankara will adopt those functional patterns while expanding scale, road geometry variety and seasonal traffic profiles.
Key Technologies and Integration Strategy
The project integrates multiple subsystems to deliver reliable CAV services:
1. Roadside units (RSUs) — deploy 5G radio and DSRC/ITS-G5 fallback, run local edge services to offload latency-sensitive tasks and provide redundancy.
2. Central control centers — host fusion engines that aggregate sensor feeds, manage traffic flows and push advisories to vehicles and variable message signs.
3. Sensor networks — camera analytics, radar, loop detectors and meteorological stations feed a unified traffic state model.
4. Communications stack — prioritized V2X channels for safety messages, QoS for streaming maps and OTA updates for vehicle software.
Practical Examples of Use Cases to Be Tested
Planned operational scenarios include:
Cooperative adaptive cruise control (C-ACC) — test platooning stability on motorway sections using coordinated speed and gap control.
Signal phase and timing (SPaT) services — reduce intersection delays by informing vehicles of phase timing via V2I messages.
Dynamic variable speed limits — use real‑time incident and weather data to manage flows and reduce shockwaves.
Tunnel and long‑span safety systems — integrate tunnel control, ventilation and electronic tolling with CAV alerts to manage mixed human and automated traffic.
Operational Design: How Traffic Will Be Monitored and Managed
Traffic operators will use the Ankara Main Smart Transport Systems Center and regional hubs to observe road state in real time. A step‑by‑step operational loop will run as follows:
Step 1: Sensors detect flow, incidents or adverse weather.
Step 2: Edge nodes preprocess data and raise alerts to the regional center.
Step 3: Fusion engines correlate feeds and predict short‑term evolution.
Step 4: Control center issues targeted advisories—variable message signs, in-vehicle warnings, or automated speed constraints.
Step 5: Logged telemetry enables continuous model retraining and system tuning.
Data, Security and Interoperability Considerations
Reliable operation requires disciplined data governance. The project will implement:
Data partitioning — separate safety-critical telemetry from analytics streams to limit attack surface.
Authentication and encryption — mutual TLS and hardware-backed keys on RSUs and vehicle endpoints.
Standard interfaces — adherence to ETSI ITS and ISO/SAE messaging profiles to ensure vendor interoperability and future scalability.
Expected Benefits and Measurable Targets
With integrated systems, the corridor aims to deliver measurable improvements in:
Traffic safety — reduced incident rates through rapid detection and coordinated advisories.
Throughput — smoother flow via dynamic speed harmonization and platooning trials.
Traveler information — enhanced punctuality and route choice from real‑time, in‑vehicle guidance.
Project milestones will include RSU coverage percentage, end‑to‑end latency under 50 ms for safety messages, and demonstrable reductions in delay during pilot scenarios.
How This Project Advances Turkey’s CAV Capability
The Ankara corridor moves Turkey from localized pilots to an interoperable regional backbone. It creates an infrastructure template—combining communications, sensing and operations—that other corridors can replicate. By validating end‑to‑end workflows and security models at scale, the project lowers technical and regulatory friction for commercial deployment of higher automation levels.
What Stakeholders Should Expect Next
Transport authorities will phase installations, beginning with critical RSU nodes and regional center software, followed by progressive activation of sensor arrays and in‑vehicle services. Vehicle manufacturers, telecom operators and traffic management vendors will engage in interoperability testing and joint demonstrations. Public updates will track performance metrics and safety validations as the corridor moves from lab verification to live road trials.
Summary: A Strategic, Scaled Testbed for Connected Mobility
This 247 km Ankara smart corridor assembles tested technologies, operational learnings and security practices into a scalable CAV ecosystem. It targets concrete performance metrics, supports diverse use cases from platooning to tunnel management, and sets a national precedent for integrating smart transport systems with traffic operations at scale.
