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


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


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


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


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)


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


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


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


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



– 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)


Concepts & proposed classifications– Distance travelled: The distance traveled in direct line

(kms)• < 50• 50 - < 100• 100 - < 200• 200 - < 500• 500+

– Age of traveller (years):• < 15• 15 – 24• 25 – 44• 45 – 54• 55 – 64• 65 +



– Household size: The number of all members in the

household• 1• 2• 3• 4• 5+
