Mission

One of the few Danube crossings.
Every vehicle must pay. Every time.

The ferry crossing in Călărași county is one of the few Danube crossings in the region. With so few crossings over the river and heavy traffic in the area, a fast, seamless crossing experience for drivers is essential.

The ferryboat links Romania to the Bulgarian town of Silistra. S.C. "Coslo Zinca" S.R.L. Călărași operates two ferryboats on the Danube, with route connections to Constanța and Silistra, Bulgaria. Each crossing takes approximately 15 minutes and carries up to 100 passengers, 50 cars, and around 12 trucks.

The ferry operator needed an automated toll collection system that could handle 13 different vehicle tariffs — from individual passengers to heavy trucks priced by length and weight — while eliminating the manual process that was prone to errors, whether accidental or intentional.

Solution

Installed live. Zero downtime.
Revenue tripled.

The Călărași project was one of the most complex logistics and installation challenges for the Metrici LPR team — the entire implementation had to be completed without interrupting ferry operations or traffic flow.

Without stopping the vehicle queue, the team installed barriers, cameras, and LAN controllers on both sides of the river. Initially, Metrici LPR was used for its database capabilities — events were recorded automatically, but tickets were issued manually by operators.

The integrators installed two Hikvision 2CS2T32 LPR cameras, two additional Hikvision cameras for ambient imaging, two barriers, and two LAN controllers to operate them. In a second phase, Metrici LPR was integrated with three Datecs cash registers.

      The Metrici team developed the Toll Station module specifically for this project. After seeing the system's initial performance, Coslo Zinca requested a fully customized solution. The resulting Toll Station module automates the entire crossing process — from plate detection to ticket issuance to barrier control — and is now available to all Metrici users.
    

Ferry Crossing Process

Step by Step · Both sides of the Danube

The system operates on both banks of the Danube. Tickets are valid for the duration of the crossing and are validated by the operator before the barrier opens.

STEP 01

Vehicle Approach

As a vehicle approaches the ferry terminal, the LPR camera captures and reads the license plate.

STEP 02

Vehicle Classification

The system classifies the vehicle into one of 13 tariff categories based on type, length, and weight — from passengers to heavy trucks.

STEP 03

Ticket Issuance

A crossing ticket is automatically generated from the Metrici LPR Web Interface, with the correct fare applied based on the vehicle classification.

STEP 04

Operator Validation

The ferry operator validates the ticket. Once confirmed, the barrier opens automatically and the vehicle boards the ferry.

STEP 05

Cash Register Integration

The transaction is logged through three integrated Datecs cash registers, ensuring accurate financial records and reconciliation.

STEP 06

Return Crossing

The same process runs on the opposite bank. Tickets are valid for the crossing duration and validated by the operator before the return barrier opens.

Toll Station module created

The custom solution developed for Coslo Zinca became the Metrici Toll Station module — now available to all Metrici LPR users worldwide.

The project demonstrated Metrici's ability to deliver under challenging conditions — installing a fully functional LPR toll system on an active ferry terminal, on both sides of the Danube, without a single minute of operational downtime. The Toll Station module that emerged from this project is now a standard offering in the Metrici LPR product line.
