1. This information is obtained from the Scottish Household Survey Travel Diary questions about the (stages of) journeys which the respondent had said that he or she made as the driver of a car or van The table does not include those (stages of) journeys for which the questions about traffic congestion were not asked
2. Car drivers were asked "was this part of your trip delayed due to traffic congestion?". No definition of "traffic congestion" is given, so respondents can interpret the term as they wish.
3. Those drivers who said that they had been delayed by traffic congestion were asked "how much time do you think was lost due to traffic congestion?".
4. Data is not shown for sample sizes below 100.
