Measuring road traffic volume through passenger mobility surveys Vasilis Nikolaou AGILIS SA Task Force on statistics on the volume of road traffic (vehicle-kilometres), 21-22/09, 2006

Background information –Agilis’ aim as contractor of Eurostat: To assist in the further development of the Community statistics on passenger mobility Emphasis is given on car passenger mobility –Specific contract tasks: Updating the non-harmonised database of national surveys on passenger mobility Updating the methodological analysis of the existing surveys on passenger mobility Proposing a set of indicators for measuring passenger mobility and particularly car passenger mobility –This presentation describes proposed indicators relevant to measuring road traffic volume

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Passenger mobility surveys –Passenger mobility surveys are: Mainly household surveys, but also Surveys of companies whose main activity is passenger transport –Their aim is to describe travel behaviour –They are running regularly in at least one third of the EU25 member states, candidate and EFTA countries –Mobility surveys are car-specific in three of them (Bulgaria, Estonia, Romania). ‘Car’ means private car, coach, bus, etc. In Bulgaria and Romania such surveys are surveys of companies

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Information collected in passenger mobility surveys –Travel undertaken during the reporting period Specific type of travel, e.g. professional trips – Travel-related information involves: Origin and destination Total distance Purpose Travel time Modes of travel Sequence of modes Duration of stay at destination Status of respondent (driver or co-passenger) Car owned by respondent or not Number of co-passengers

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Information collected in passenger mobility surveys –Socio-economic characteristics Age Gender Place of residence Employment status Occupation Education Marital status Number of adult persons within the households Level of urbanization Income Car ownership Number of cars within the household Driving license

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Passenger mobility indicators compiled –Average number of trips/person/day by Mode of transport Purpose of travel Distance class Age of respondent –Average travel distance (km)/person/day by Age of respondent –Average total travel time(min)/person/day by Mode of transport Purpose of travel –Passenger-kilometres (Bulgaria) by type of passenger traffic (Urban, Coach, International) –Vehicle-kilometres (Germany)

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Proposed car passenger mobility indicators –Car VKMs –Car PKMs by Type of fuel (diesel, gasoline) Distance travelled Purpose of travel Distance travelled by purpose Age by gender of passenger Purpose of travel by age by gender (optional) Car passenger status (driver, co-passenger) –Objective: To describe daily car mobility and fuel consumption

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Proposed car passenger mobility indicators –Average total travel time/person/day(minutes) by Purpose of travel Distance travelled Distance travelled by purpose Age by gender of passenger Car passenger status (driver, co-passenger) –Average travel distance / person / day (km) by Purpose of travel Type of fuel Age by gender of passenger Car passenger status (driver, co-passenger) –Objective: To describe daily car mobility and assess congestion

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Proposed car passenger mobility indicators –Number of trips/person/day by Purpose of travel Age by gender of passenger Car passenger status  Objective: To describe daily car mobility –Number of cars in the household by Number of adult members of household  Objective: To understand factors affecting car ownership –Car occupancy rate (PKM/seat-kilometre) by Distance travelled  Objective: To assess rational use of cars

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Concepts & proposed classifications –Main mode of transport: The mode used for the longest part of a trip or journey Non-motorised private transport –Walking –cycling, –other non-motorised Motorised private transport –passenger car (driver or passenger) –other motorised private transport Public transport –Bus&coach –Rail –Air –Water –Other public transport

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Concepts & proposed classifications –Purpose of travel: The main purpose of a journey or a trip without which the journey or a trip would not have occurred Work (travel to/from regular working place) Education (travel to/from school, conference, seminars etc) Shopping Business (meeting clients, other professional activities) Leisure (all other personal purposes, like culture, sports, going to restaurants)

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Concepts & proposed classifications –Distance travelled: The distance traveled in direct line (kms) < < < < –Age of traveller (years): < – – – –

Task Force on statistics on the volume of road traffic (vehicle- kilometres), 21-22/09, 2006 Concepts & proposed classifications –Household size: The number of all members in the household
