Abstract:

This paper describes using passive Global Positioning Systems (GPS) data collection and Geographic Information System (GIS) with participant prompted recall to study the travel habits of rural older drivers. It is based upon the research of a convenience sample of 60 rural drivers (29 men, 31 women, average age 69.6 years) in New Brunswick, Canada. The transportation needs of a growing population of older rural residents, many who face the risk of not being able to meet their needs if they can no longer drive, are not well understood and represent an immediate and future policy need. GPS-based travel diaries are a useful method to obtain origin/destination and other contextual information in support of rural transportation planning. A total of 1,649 “stops” (periods of non-movement lasting 1 minute or more) by participant vehicles were recorded with the GPS units. Approximately 8% of all “stops” were due to stoplights or traffic delay. The remaining “stops” were organized into 1,494 trips (one origin with one destination), with participants supplying purposes, who was driving, and passenger details for 99.1% of recorded trips. Travel data were collected on average for 5.3 days per participant. An external battery for the GPS unit minimized the typical satellite acquisition but was exhausted in 10% of cases. Only 2.2% of recorded trip ends were due to lost reception or acquisition delay and in each case the missing distance data were interpolated. Service clubs and snowball sampling were the most effective means of recruiting rural participants.
