Mission

Bulgaria's biggest truck parking lot.
Built for the EU-Turkey border.

One of the largest Metrici parking projects to date — over 500 parking spaces for trucks and cars, monitored and managed entirely with Metrici Parking Place Detector.

The parking lot is situated at the Bulgarian border crossing to Turkey. Since Bulgaria is an EU member state and Turkey is not, the border transit process is highly time-consuming for every vehicle — especially for trucks on both sides of the border.

Until now, all trucks were lined up along the highway when trying to exit the EU. The queue was often more than 5 kilometers long — an unpleasant situation for both truck drivers and other road users. The many hours spent waiting in line also meant large amounts of garbage produced by drivers, often left littering the road and its shoulders.

The client decided to build the biggest truck parking lot in Bulgaria, giving drivers a decent place to wait at the border — complete with restaurants, toilets, a sitting area, and a shopping center.

But keeping 500+ spaces under control is no easy task. The system needed to record each driver's entry data, track stay duration, calculate the fee on exit, and guide drivers to available empty parking spaces. This is where Metrici showed its potential.

Solution

40 cameras. 40 engines.
Every space tracked in real time.

The Metrici partner and integrator from Bulgaria, Maxtel, proposed a solution to better manage the large infrastructure using automated systems and the AI capabilities of Metrici software.

The entire parking facility is monitored using Metrici Parking Place Detector. Forty IP cameras were installed on 9-meter poles around the parking lot, each monitoring dozens of parking spaces simultaneously.

Forty Metrici detection engines were installed on two servers working together — one serving as the central server for data centralization and interface access.

      Metrici PPD was the ideal choice for this project. The AI-based Parking Place Detector monitors every space in real time, tracks vehicle entry and exit, calculates stay duration, and guides drivers to available spots — all without any physical sensors in the parking spaces themselves.
    

How the Parking System Works

Step by Step · From entry to exit

The parking lot is organized as a large roundabout — trucks enter from one side and exit from the other. Each truck is guided to the most suitable available parking spot as it enters.

STEP 01

Vehicle Entry

As a truck enters the parking lot, its presence is detected by Metrici LPR. The system records the entry data and timestamp for billing.

STEP 02

LED Guidance to Available Spot

Twenty-two Metrici LED displays positioned throughout the lot guide the driver with illuminated arrows toward the nearest available parking space — preventing trucks from circling aimlessly.

STEP 03

Real-Time Occupancy Tracking

Each of the 40 cameras feeds a Metrici PPD engine that continuously monitors dozens of spaces. Occupancy changes are reflected instantly on the operator's real-time map.

STEP 04

Border Departure Call-Out

When it's time for a truck to leave for the border check, its license plate is displayed on dedicated LED screens, alerting the driver to head to the exit.

STEP 05

Exit & Fee Calculation

As the truck exits, the system calculates the total stay duration and the amount due. The event is logged in the database for reporting and analytics.

KEY FEATURE

Interactive Real-Time Map

A dedicated feature was developed for this project: the admin can upload a map of the parking lot into the Metrici Interface, designate each parking space on the map, and get an instant, fully clear view of the entire situation in a single image — updating in real time by spaces or areas.

The interactive map feature — developed specifically for this project, allowing the admin to upload a parking lot map and designate each space for real-time visual monitoring — has since been rolled out and is now available to all Metrici clients.

Results and Benefits

Proven at scale.
Expanded nationwide.

The project delivered a fully automated parking management system at a scale rarely seen — and its success led to immediate expansion.

🅿️

500+ spaces fully automated

Every parking space is monitored, tracked, and managed in real time — from entry recording to exit fee calculation — with zero physical sensors in the ground.

🗺️

Real-time interactive map

Operators get an instant, clear visual overview of the entire parking situation — updating live by individual spaces or zones.

🚛

Efficient driver guidance

22 LED displays guide trucks directly to available spots, eliminating aimless circling and reducing congestion inside the lot.

📈

Nationwide expansion

The project's success led the beneficiary to deploy the same technology across all their parking lots throughout Bulgaria.

The system not only replaced the 5-kilometer highway queues with a structured, comfortable waiting area — it also proved that Metrici PPD can handle parking operations at any scale. The interactive map feature, born from this project's needs, is now a standard capability available to all Metrici clients worldwide.
