SIPARK National Parking Platform

Basic information

The SIPARK National Parking Platform is a digital tool for effective parking management at the level of settlements, cities, municipalities, regions, and the state. It supports sustainable transport policy by enabling comprehensive implementation of parking strategies.

The platform allows for the collection, structuring, and dissemination of standardized static and dynamic data on publicly accessible parking spaces and facilities across Slovenia. It serves as the foundation for a unified, publicly accessible national parking database (a repository of open and standardized data).

The database is compliant with DATEX and APDS standards and enables data exchange with other countries or data users (e.g., web platforms or mobile applications for vehicle navigation, driver information, or parking facility management).

Elements in the Hierarchy of Parking Infrastructure

A parking facility can be described in a simple way using a single hierarchical element (if the entire parking area constitutes a uniform unit in terms of its attributes), or it can be broken down into a multi-level hierarchy to identify components with the same properties.

This hierarchical structure allows municipalities or parking operators to choose the appropriate level of detail when entering data into the parking database.

Parking facilities may be defined at the following levels:

  • parking place
    (parking facility)
    The primary entity, referring to a structure or area associated with vehicle parking or mobility services.
  • subparking
    (subparking area)
    A subdivision of complex facilities (e.g., levels in parking garages or combinations of outdoor and garage parking) into operationally homogeneous areas. Optional element.
  • identified area
    (group of parking spaces)
    A cluster of parking spaces sharing the same characteristics (e.g., payment regime, price, opening hours, height clearance, designated usage such as disabled, e-vehicles, bicycles, delivery vehicles, etc.). Mandatory if a hierarchical structure is created.
  • campus
    A possible grouping of multiple parking places (e.g., Tivoli Car Park, BTC Ljubljana). Optional element.
  • parking Space
    (individual parking space)
    The lowest hierarchical level, which can only belong to a »Group of Parking Spaces«, which in turn belongs to a parking place or subparking area.

Benefits

Benefits of Comprehensive Data Collection and Regular Data Updates in SIPARK for Municipalities and Parking Operators:

  • Support for active parking policy and spatial/transport planning
    (including real-time user information, improved parking utilization, reduced unnecessary vehicle mileage, lower energy consumption, and fewer greenhouse gas and air pollutant emissions).
  • Support for efficient parking management and smart city integration
    (via third-party plugins for analytics, forecasting, integration with reservation systems, parking guidance, payment systems, and Mobility-as-a-Service (MaaS) solutions).
  • Enables measurement and analysis of parking occupancy
    (e.g., mobility pattern analysis, predictive traffic modeling).
  • User-friendly system for capturing and managing parking data
    including complex opening hours, tariffs (through the SIPARK platform or exchange files).
  • Data export options
    in formats such as CSV, SHP, GML, and GeoJSON – for both outlines and point data – as well as DATEX-compliant files.

Key Stakeholders in Parking Policy

The following groups are key stakeholders in parking policy development and implementation:

  • National authorities
  • Municipal administrations
  • Regional development agencies and regional mobility centers
  • Transport and spatial planners
  • Parking facility operators
  • Mobility-as-a-Service (MaaS) providers
  • Drivers

Data Categories

Static Data (infrequently changing):

  • Basic parking place information
  • Location data
  • Operator and owner details
  • Equipment and services provided
  • Opening hours
  • Tariffs
  • Access information
  • Photos and documents

Dynamic Data:

  • Real-time occupancy information

User Roles

  • Administrator and System Manager: Ministry of the Environment, Climate and Energy.
  • Data Entry User (External Stakeholder): A representative of an external stakeholder authorized and responsible for data input or process execution.
  • Data Manager (External Stakeholder): A user authorized to edit (input and modify) data on parking places under their management, review data, and submit data entry requests.
  • Reader (Read-only Access): Open external access for reading data as configured, including public end users seeking parking data via the NAP portal (national access point).

Data Access

Data can be accessed via the data page (see portal). Access requires prior user registration, admin approval, and acceptance of general terms of use.

To ensure compatibility, interoperability, and continuity of services, data is collected and exported via the NAP in the DATEX II format. Data is available for real-time exchange and reuse on a non-discriminatory basis.

The NAP Slovenia portal also provides a high-quality user experience for drivers, including map-based search and display of parking information.

Funding and Development

SIPARK Platform Access and User Registration

The establishment of the SIPARK National Parking Platform was co-financed through the Soft Measures for Sustainable Mobility operation, partially funded by the European Union under the Cohesion Fund.

The operation was implemented under the Operational Programme for the Implementation of the EU Cohesion Policy 2014–2020, Priority Axis 4: Sustainable use and production of energy and smart grids, Investment Priority 4.4: Promoting low-carbon strategies for all types of territories, especially urban areas, including support for sustainable multimodal urban mobility and appropriate mitigation and adaptation measures, within the Specific Objective: Development of Urban Mobility to Improve Air Quality in Cities.
