Notes

Figures are daily averages calculated from all traffic counts over the course of the year.

Values are rounded to the nearest whole number.

A value of zero for any entry means that there were either no recorded vehicles of that type or too few to register after rounding.

A blank value means that there were no counts made in that year.

Click or tap on the column headings to see a pie chart of the data.
