Transportation Tomorrow Survey

The Transportation Tomorrow Survey (TTS) is a comprehensive travel survey conducted in the Greater Toronto and Hamilton Area (GTHA) once every five years. The TTS is a joint undertaking by the agencies represented on the Transportation Information Steering Committee (TISC), formerly known as the Toronto Area Transportation Planning Data Collection Steering Committee (TATPDCSC). The Committee was established in 1977 for the purposes of setting common transportation data collection standards and for coordinating data collection and dissemination between the member agencies. Membership of the committee includes Cities of Toronto and Hamilton, the Regional Municipalities of Durham, Halton, Peel and York, GO Transit, the Toronto Transit Commission and the Ontario Ministry of Transportation.

The first TTS, conducted in 1986, obtained completed interviews for a 4.2% random sample of all households in the GTA. After completion of the 1986 survey, the Data Management Group was formed at the University of Toronto with one of its prime objectives being the management and distribution of the 1986 TTS data. The Data Management Group was also requested to manage the second TTS undertaken in 1991. The 1991 survey was a smaller update of the 1986 survey focusing primarily on those geographic areas that had experienced high growth since 1986. The survey area was expanded slightly to include a band approximately one municipality deep surrounding the outer boundary of the GTA for the purpose of obtaining more complete travel information in the fringe areas of the GTHA.

The 1996 TTS was a new survey, not an update. Agencies outside of the GTHA were invited to participate. The survey area was expanded to include the Regional Municipalities of Niagara and Waterloo, the counties of Peterborough, Simcoe, Vicoria and Wellington, the Cities of Barrie, Guelph, and Peterborough and the Town of Orangeville. Approximately 115,000 interviews were completed representing a 5% random selection of households throughout the survey area. To coordinate the survey a technical sub-committee of TATPDCSC was established that included representation from all the participating agencies. The Data Management Group was responsible for all aspects of the management of the survey.

The 2001 TTS was essentially a repeat of the 1996 survey with approximately 137,000 completed interviews. The survey area was the same as in 1996 except for the exclusion of the Regional Municipality of Waterloo and inclusion of City of Orillia and all of the County of Simcoe. The organizational structure and the role of the Data Management Group were also the same as for the 1996 survey.

In a manner similar to the 2001 TTS, the 2006 TTS was another repeat of the 1996 survey with approximately 150,000 completed interviews. The survey area was the same as in 2001 with the inclusion of the Regional Municipality of Waterloo, the City of Brantford and the County of Dufferin. The organizational structure and the role of the Data Management Group remains the same.

The 2011 TTS covers a similar survey area as in 2006, with the addition of the County of Brant. The survey was conducted in the fall of 2011 and 2012, and contains approximately 160,000 completed interviews.

The 2001, 2006 and 2011 surveys are three of the largest travel surveys ever undertaken anywhere. The 1986, 1991, 1996 and 2011 surveys each involved a major element of technology development. The use of automated geocoding was a key development in the 1986 survey. On-line Direct Data Entry (DDE) was introduced in the 1991 survey and networked computers in the 1996 survey. There was no comparable technological advance for the 2001 survey. The survey methods remained essentially unchanged from 1996 through 2001 to the 2006 survey. The computer software supporting these survey procedures received a major update for the 2006 TTS. In the 2011 TTS, a new web based component was introduced. Selected households were able to complete the survey online with their unique secure access codes. Analyses will be conducted to evaluate the results of this new component.
