STUDY UPDATE as of May 2015

As most of you know, we are completing Year 6 data collection and will be beginning Year 7 assessments this summer. Analysis of our complete set of Year 4 and Year 5 data is underway and we will be working on further analysis for our risk stratification tool this summer. This fall we plan to hold another site investigator meeting where we will be discussing further plans for our risk stratification tool as well as making deicisons about future directions. Candrive site investigators continue to work with our data and have been publishing in transportation and aging journals.


Overall, we continue to progress as planned and hope to be coming to the close of data collection at the end of this year, December 2015.

We want to thank you for your continued support of our important driving study. Your involvement provides the science-based data needed to help influence driving policies and change driving practice that will help to save lives.

These pages are designed to keep you informed of the study progress and provide other information we think might be of interest. We also would like to hear from you; your views, concerns, and experiences as a participant.

Candrive Knowledge Translation

  • Knowledge translation is defined as a dynamic and iterative process that includes synthesis, dissemination (broadcasting), exchange and ethically-sound application of knowledge to improve the health of Canadians, provide more effective health services and products and strengthen the health care system.*
  • The table below displays the number and types of knowledge translation activities Candrive investigators have been involved with to date (June 2015).

Candrive Researchers Participate in

National and International



July 5 - 6 2012

Candrive investigators, researchers and students from all sites have begun to present some of our initial findings at local, national and international conferences. Investigators attended the Canadian Association on Gerontology (CAG) 40th Annual Scientific and Educational Meeting, celebrating "New Directions for Aging," in Ottawa, Ontario from October 21-23, 2011. Various topics were discussed in a symposium about Candrive research, including findings on the influence of psychological and social factors on driving decision-making and behaviour, a comparison of our study participants to the general older driving population and the use of driving simulators.

In addition, Candrive researchers attended the 22nd Canadian Multi- disciplinary Road Safety Conference in Banff, Alberta on June 10-13, 2012. This conference is aimed at everyone who works in driver safety including health professionals, government officials, researchers and more. Candrive investigators and researchers also presented at the International Conference on Aging, Mobility and Quality of Life at the University of Michigan, USA on June 24-26, 2012. This conference focused on the particular requirements of elderly people for transport/ mobility that give them access to the various activities and services that maintain their health and well-being and enhance their quality of life.

Dr. Shawn Marshall, along with our Australian partners, attended the Australasian Road Safety Research, Policing and Education Conference in Wellington New Zealand, October 4-6th, 2012. Researchers were fortunate enough to have the opportunity to collaborate and present 12 abstracts as part of a Candrive/Ozcandrive Symposium on Older Drivers

Summer Students!


This year candrive has hired 5 summer students to help with Candrive and its subprojects. The students will be working on new publications & data management, among other things.Our goal is to provide skills that these students can take with them to prepare them for future careers.

With all this help we expect to have an exceptionally productive summer!
