Traffic regulations and restrictions :

The dataset provides an overview of the static permanent access regulations that apply to Luxembourg motorways. However, the access restriction definitions related to tunnels are not limited to motorways; they cover the entire national road network.

Access restrictions specify which types of vehicles are permitted to use specific road sections and under which conditions. These conditions include height limits, weight restrictions, speed regulations, overtaking bans for heavy-duty vehicles (HDV), and other parameters.

The digital restrictions in this dataset are derived from Luxembourg’s National Road Code “Code de la Route” and are aligned with relevant European standards. The digital dataset provides a structured overview of static restriction rules. The data feed provided does not replace the legally binding provisions defined in national official regulatory texts which can be found in the Journal officiel du Grand-Duché de Luxembourg - Legilux (https://legilux.public.lu/) .

The dataset consists of static definitions on:

· Access conditions for tunnels (entire national road network)

· Access conditions for bridges (motorways)

· Overtaking bans on heavy-duty vehicles (motorways)

· Permanent access restrictions (for vehicles on motorways)

The following restriction parameters are included:

· height of vehicle (in meters)

· width of vehicle (in meters)

· speed limits for heavy-duty vehicles and other vehicles (in kilometers per hour)

· overtaking ban of heavy-duty vehicles (HDV threshold, in tons)

· minimum distance of vehicles (in meters)

· gross weight of vehicle (in tons)

· axle weight of vehicle (in tons)

· tunnel category (dangerous goods class)

· length of vehicle (in meters)

Legal Basis (1/2) – EU level

The defined access restrictions correspond to several data categories listed in the European Commission Delegated Regulation (EU) 2022/670 of 2 February 2022, which supplements Directive 2010/40/EU concerning the provision of EU‑wide Realtime Traffic Information (RTTI) services. The relevant sections of Annex I included in this dataset are:

(2) Crucial types of data on regulations and restrictions:

· (a) static traffic regulations, where applicable:

· ---- (i) access conditions for tunnels

· ---- (ii) access conditions for bridges

· ---- (iii) permanent access restrictions

· ---- (vi) overtaking bans for heavy goods vehicles

Important: This feed is supplied to meet EU requirements for digital access restriction data. Although maintained with care and based on applicable permanent rules, the feed is not legally authoritative and may contain inaccuracies or omissions. This dataset is provided for informational purposes only and does not replace the legally binding texts or on‑site traffic signage and/or control devices.

Legal Basis (2/2) - National Level

The restriction definitions in this dataset are a non-binding, digital representation of the relevant provisions of the “Code de la route du Luxembourg”. Users are responsible for consulting the latest, officially published legal texts. The corresponding legal articles which form the regulatory basis for this interpretation are found in https://legilux.public.lu/, specifically concerned are:

« Arrêté modifié grand‑ducal du 23 novembre 1955 portant règlement de la circulation sur toutes les voies publiques — Art. 3, Art. 4, Art. 6, Art. 12, Art. 107, Art. 126, Art. 139, Art. 141. »

Important: The legal text of the “Code de la route du Luxembourg” constitutes the sole legally binding source for the applicable access restrictions and traffic regulations. Accordingly, traffic signs, road markings, and any on‑site regulatory measures remain fully applicable and must be observed by the driver at all times. Drivers retain full responsibility for complying with the “Code de la route” of Luxembourg and all legally established traffic control measures while driving.

File Format

The dataset is provided in DATEX II version 3.6. The corresponding DATEX II Model is included to ensure full compatibility with the underlying data model. The following example illustrates a condition set used to define tunnel access restrictions:

----- tro:condition (xsi:type="tro:ConditionSet")

----- tro:operator = "or"

----- tro:conditions (xsi:type="tro:VehicleCondition")

---------- tro:vehicleCharacteristics

-------------- com:grossWeightCharacteristic

------------------ com:comparisonOperator = "greaterThan"

------------------ com:grossVehicleWeight = 44.0

------------------ com:typeOfWeight = "maximumPermitted"

----- tro:conditions (xsi:type="tro:VehicleCondition")

---------- tro:vehicleCharacteristics

-------------- com:heightCharacteristic

------------------ com:comparisonOperator = "greaterThan"

------------------ com:vehicleHeight = 4.0

----- tro:conditions (xsi:type="tro:VehicleCondition")

---------- tro:vehicleCharacteristics

-------------- com:widthCharacteristic

------------------ com:comparisonOperator = "greaterThan"

------------------ com:vehicleWidth = 2.55

----- tro:conditions (xsi:type="tro:VehicleCondition")

---------- tro:vehicleCharacteristics

-------------- com:heaviestAxleWeightCharacteristic

------------------ com:comparisonOperator = "greaterThan"

------------------ com:heaviestAxleWeight = 12.0

----- tro:conditions (xsi:type="tro:TunnelCategoryCondition")

---------- tro:negate = true

---------- tro:tunnelCategoryType = "categoryA"

----- /tro:condition

Extensions “B-Level”

A B-Level extension is incorporated into ‘implementedLocation’ in accordance with DATEX II v3.6 extension principles. It contains two complementatry aspects:

· In addition to the primary location‑referencing method—encoded as a GML LineString based on the OGC‑compliant spatial reference EPSG:4937—the extension provides a second LineString definition within linearLocationExtension, encoded in EPSG:9895.

· The Level-B extension may – where applicable - include additional information relevant to the respective road item type, as illustrated in the example below:

--- tro:implementedLocation (xsi:type="loc:LinearLocation")

------ loc:supplementaryPositionalDescription

---------- loc:lengthAffected = 395.0

---------- loc:roadInformation

-------------- loc:roadDestination = A13 vers Pétange

Data Accuracy & Temporal Validity

The dataset provides an accurate representation of the legally established access restrictions at the time of verification. However, as updates take place only at defined intervals, minor deviations may occur between the verification date and the next update.

The dataset is manually validated and maintained with great care. Because updates are infrequent and the underlying parameters are stable, the likelihood of human error is considered very low. Any such occurrences are expected to be exceptional.

Revision Cycle

The dataset contains static, long‑term access restrictions that typically change only after structural modifications or revised regulatory decisions. As a result, updates are generally rare.

To ensure that any changes are captured within an appropriate timeframe, the dataset is subject to a minimum annual revision cycle. This guarantees that updates, even if infrequent, are incorporated regularly.

Temporal Coverage

The dataset represents permanent, infrastructure‑defined access restrictions that were legally established in accordance with the provisions described under “Legal Basis” chapter. Because these access restrictions are permanent in nature, no explicit start or end date of temporal coverage is defined. The dataset was verified on 31.12.2025 and reflects the manually validated legal situation as of that date.
