Glossary
Accident
The term accident or crash, refers to an event where two or more vehicles collide or when a motorized vehicle impacts against one or more vulnerable road users (pedestrian, cyclist) or impacts against an object.
Accident fatalities
All people that have died because of a traffic accident. This includes people that have died in the place of the accident, during the accident or people that have died within 30 days after the accident because of the wounds/health problems caused by this event.
Accident victims
All people involved in an traffic accident. In the BMD, the term victim comprehends all of the types of victims defined by STATBEL (not injured victims, slightly injured victims, severely injured victims and fatalities).
Average time lost per working person due to congestion
Is the total excess travel time due to congestion divided by the working population. This value is calculated for different time spans (daily average, monthly average or YTD average).
Bicycle counters
Devices installed next to the main bicycle paths in Brussels region to count and register the number of cyclists that pass through that point of the bicycle network along the day.
Bicycle flows
The total number of bicycles that passed through a specific point of the bicycle network in a certain period of time (hour, day, week, month, year).
Car subtypes
For cars specifically, the following subtypes have been determined, based on the segmentation defined and used by FEBIAC: Micro cars (mini-compact and town cars), Small cars (medium compacts, small breaks, small jeeplike cars, small monospaces), Medium cars (medium estate cars, medium minivans/MPVs, medium jeeplike cars, medium superiors), Large cars (superior breaks, superior luxury, big monospaces, big jeeplike cars, exception limousines, combis) and Special cars (coupés, convertibles, roadsters, 4x4, sports cars).
Commercial speed of public transport
“The commercial speed is calculated by dividing the distance traveled in commercial trips( with customers) by the real total time of the commercial journey, including traffic time and commercial and non-commercial stops (stops in front of traffic lights, congestion, ...). ” (STIB)
Congestion (also road congestion)
A situation where there are excessive vehicles on a road (difference between optimal flow and non-optimal flow on the road), resulting in speed reduction and longer travel times. Therefore, congestion comprehends traffic jams but also speed reductions.
Congestion length
The total length of congested road segments. Congestion length is measured constantly throughout the day.
Cost of congestion
The economic cost due to congestion, expressed in millions of euro or as a percentage of GDP (%). The economic costs generated by congestion throughout the day include time losses, excess fuel consumption and the cost of excess emissions. They are converted into monetary values.
Delay at arrival
The average train delay on arrival at a specific station. The delay is expressed in minutes (‘) and seconds (‘’).
Delay per route
The average delay of all train arrivals on a specific train route. The delay is expressed in minutes (‘) and seconds (‘’). Every Origin-Destination pair is one route. For instance, the Liege Saint Lambert – Mons line is one route, while the Mons – Liege Saint Lambert line is another route.
Engine type
The BMD covers the following types of engine: Petrol, Diesel, Plug-in hybrid electric (PHEV), Hybrid (HEV), Full electric or battery electric (BEV), Compressed natural gas (CNG), Liquefied natural gas (LNG), Liquefied petroleum gas (LPG), Hydrogen and Fuel cell electric (FCEV).
Entries at STIB stations
The number of people passing through entry gates at the metro and tram stations of the public transport provider STIB. This number takes into account only the entries into the stations equipped with physical control access gates.
EV charging connector
A physical connector or charging point where a full electric vehicle (BEV) or a plug-in hybrid vehicle (PHEV) can be connected to be charged.
EV charging station
A charging station where it is possible to charge a full electric vehicle (BEV) or a plug-in hybrid vehicle (PHEV). A charging station can be equipped with one or more connectors and from different types, therefore some EV charging stations can charge multiple electric vehicles and at different speeds.
EV fast charging
Some charging connectors that offer high charging power (kW) and/or equipped with special type of plugs (ex. CHADEMO), allow the charging of electric vehicles (BEV or PHEV) at considerable higher speeds than conventional charging connectors.
Excess travel time (or delay)
The difference in time between driving with or without congestion. Excess travel time can have absolute values (minutes, hours) or relative values (%).
Existing fleet
Fleet of vehicles with active license plates registered in Belgium and counted at a specific time or date.
Gross domestic product (GDP)
"The GDP is the total of all value added created in an economy. The value added means the value of goods and services that have been produced minus the value of the goods and services needed to produce them, the so-called intermediate consumption." (European Commission)
Maximum congestion length
The maximum congestion length registered in the most congested hour of a given period of time (day, week or month).
Multimodal point/node (MMP/MMN)
A multimodal point/node refers to a spot where two or more public transport (PT) modes are available and close enough to each other to facilitate a fast transfer of passengers between them. The public transport modes in question are: train, metro, tram, bus and public bicycle parking.
NEDC
The old NEDC, known as the ‘New European Driving Cycle’, was the EU offical standard for determining the levels of pollutants, CO2 emissions and fuel consumption of new types of car and van models until 2017. It has been replaced by the WLTP.
New vehicle registrations
Refers to the registration of new vehicles in a given year.
Ownership types
The BMD covers the following types of vehicle ownership: Corporate (vehicles registered by companies/institutions), Leased (vehicles registered by leasing companies), Private (vehicles privately registered by individuals) and Private VAT (vehicles registered by self-employed individuals).
Repartition of entries at STIB stations
Is the share or distribution percentage of entries at STIB stations along the day. In simple words, is the percentage of people entering the stations at every hour in comparison to the total number of people that entered the station on that day.
Road
The roads in the BMD cover all of Belgium and include the highways and the main roads used for travel in and between cities.
Road segment
A portion of a road in the road network.
Train punctuality (%)
“The general punctuality figure represents the percentage of trains that were less than six minutes late at their final destination” (INFRABEL).
Vehicle Types
Vehicle types were classified based on the Belgian technical regelation (RD dd 18.03.1968): Cars (vehicles for the transport of passengers with a maximum of eight seats, without taking into account the driver's seat), Vans (light commercial vehicles with a maximum permissible weight <= 3.5 tonnes), Trucks-lorry type (heavy commercial vehicle with maximum permissible weight exceeding 3.5 tonnes and where the cargo compartment is part of the vehicle), Trucks-tractor type (heavy commercial vehicle designed exclusively to haul other road vehicles which are not power-driven), Motorcycles-moped type (2-wheeled vehicles with a cylinder capacity <= 50cc and maximum speed <= 45km/h) and Motorcycles-regular type (2-wheeled vehicles with a cylinder capacity > 50cc).
WLTP
The Worldwide harmonised Light-duty vehicles Test Procedure (WLTP) is the new global official standard for determining the levels of pollutants, CO2 emissions and fuel consumption of new types of car and van models. It has replaced the old regional official NEDC standard since 2017-2018.
Working population
That part of the population of working age (15-64 years) who are actually working. This includes employees and the self-employed.
Year to date (YTD)
The period that runs from the start of the year (1 January) to the current date or to the last registered time (e.g. last updated month).
