2 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit VITAL Components

3 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit VITAL Components Victorian Activity & Travel Survey (VATS) Land-Use Information Transport Network Information System Monitoring Special Surveys Demand & Supply Modelling Geographic Information System Data Support Centre

4 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Victorian Activity & Travel Survey (VATS) household travel & activity survey using self-completion questionnaire – 4 reminders, validation & non-response surveys all travel by all people by all modes 365 days per year, for five years 5,000 responding households per year – primarily Metropolitan Melbourne area residents

5 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Land -Use Information origin and destination activity sites household information – ABS CDATA-91 demographic data – VATS demographic data landmark data – geocoded locations of commonly visited sites destination land-use activities – using several data sources to create an employment datafile – Telecom Business Finder, ABS Register of Businesses, Census – 12 ASIC industry types – at the level of the Census Collectors District (each CCD contains about 300 households) Finely-grained, updatable land-use data

6 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Landmarks File 50,000 geocoded activity sites – shops – schools – train stations (bus & tram stops) – parks, beaches etc – medical facilities – government offices – banks – restaurants – sporting facilities – community facilities – churches – pubs, clubs etc

7 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Employment File employment numbers by ASIC (industry) class by CCD (Census Collectors District - the smallest Census areas) derived from – Telecom Business Finder (electronic Yellow Pages) – ABS Register of Businesses – ABS Journey to Work data

8 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit From this... to this

9 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Transport Network Information across all modes of transport traditional road capacity parameters – plus extra details of traffic control devices public transport network layouts – plus details of all stops and scheduled timetables bicycle network information derived from GIS streetfiles All compatible with GIS framework

10 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Public Transport Networks

11 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit System Monitoring ongoing performance monitoring traffic flows – using traffic signal control data public transport patronage – using outputs from automatic ticketing observational surveys – travel time surveys, on-time running etc. bus & taxi industry performance measures Aggregate control data for VATS

12 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Special Surveys in addition to the VATS data attitudinal surveys in-depth surveys (e.g. HATS surveys) stated preference surveys choice-based surveys (e.g. on-board surveys) geographically-biased surveys “rare groups” surveys Linked to the VATS sampling frame

13 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Demand & Supply Modelling prediction of consequences of change how people react to system changes how the system reacts to changes in usage economic, social & environmental impacts new public transport modelling methods use of activity-based approaches in the modelling of demand integration with TransCAD package Uses the various integrated databases

14 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Geographic Information System an electronic, multi-layered desktop map used for VATS geocoding of destinations contains multiple layers of network data holds information on land-use activities useful as an input and output medium can link to other data (e.g. accidents) MapInfo ® adopted for VITAL base data transferable to other platforms Ties the different data together

15 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Data Support Centre unlimited support to subscribers documentation covering VITAL activities installation support and training query systems for VITAL data a quarterly newsletter, “Vital Signs” people to help subscribers use VITAL people to make sure that subscribers become repeat subscribers to VITAL

16 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit History of Travel Surveys in Melbourne 1964 - Melbourne Transport Study – Wilbur Smith & Associates – 28,000 households, personal interview 1972 - MTS Update – 3,500 households in 10 LGAs 1978-79 - MoT Survey – Kinhill / Roy Morgan – 11,500 households, personal interview 1993  98 - VATS as a part of VITAL – Transport Research Centre – 5,000 households p.a., mailback questionnaire

17 VITAL The Victorian Integrated Travel, Activities & Land-Use Toolkit Victorian Activity & Travel Survey (VATS) household travel & activity survey using self-completion questionnaire – 4 reminders, validation & non-response surveys all travel by all people by all modes 365 days per year, for five years 5,000 responding households per year – primarily Metropolitan Melbourne area residents

18 VATS Sample Design Sample frame based on Melbourne Water list of residential water connections Stratified by Local Government Area Variable sampling fraction - higher sampling rate in LGAs with higher public transport usage Final sample sizes in each LGA based on balance between equal sample rate and equal sample size Sample in each LGA spread over entire period of survey Balance of days-of-week in each LGA VATS The Victorian Activity and Travel Survey

19 VATS Survey Design Initial contact letter 1st mailing – confirmation letter – household and person form – 6 trip forms – example form – postage-paid reply envelope 1st reminder/thank you - postcard 2nd reminder - letter 3rd reminder - everything again! 4th reminder - postcard The Victorian Activity and Travel Survey VATS The Victorian Activity and Travel Survey

20 Validation Exercises telephone interviews to check suspected errors or missing data validation interviews personal interviews with a random sample of respondents to check completeness and accuracy of reported travel and activities non-response interviews personal interviews with a random sample of non-respondents and refusals to * check reasons for refusals or non-response * obtain some travel data, if possible VATS The Victorian Activity and Travel Survey

21 Data Entry & Editing interactive computer-based entry screens reflect layout of survey forms in-built range and logic checking numerous “pop-ups” for pre-coded values geo-coding of all locations – household addresses – start-of-day locations – all stop destinations average trip speed checks for each mode – using geocoded locations and reported times VATS The Victorian Activity and Travel Survey

22 Data Weighting expansion of survey results to population totals using ABS CDATA-91 Census data » dwelling type x household size x SSD (18 areas) » age x sex x SSD application of non-reported trip weights derived from validation interviews application of non-response weights derived from trip rates in successive response waves VATS The Victorian Activity and Travel Survey
