Daily Travel Index
The Daily Travel Index uses a panel of GPS signals representing road trips taken specifically in cars (excludes travel by air). A trip is measured as one where the user has traveled a minimum of 50 miles and spent a minimum of 2 hours at the destination. Commuter travel or other frequently repeated trips (ie cargo deliveries or other reoccurring activities) are excluded from the Daily Travel Index. The Daily Travel Index includes all dates from January 1, 2019, to the current day.
What is an Index: An index is a measure of an average value by which relative change is measured over time.
Daily Travel Index: An index depicting the day’s trip volume to the average trip volume in 2019. A given day’s value of 0.34 means that the volume of trips on that date was 34% of the average trip volume in 2019.
Year-over-Year Change: Measures relative change in index value for the same time period prior to year. Expressed in percentage format, a value of -72.2% means that the index for 2022 was 72.2% lower than the index for the previous year for the same time period, adjusted by day of the week.
Daily Index YoY: Measures the year-over-year change in the index value for the most recent data available compared to the same day last year. In order to ensure accuracy, all year-over-year changes reflect the day of the week so that a Friday this year is compared to the same Friday in the previous year.
Weekly View: This allows you to aggregate the index into a weekly format, which follows a Sunday to Saturday format.
Monthly View: This allows you to aggregate the index into a monthly format.
