The current data release covers the period 03/06/2019 to 07/06/2021 over 1 hour time periods.
Please note that this sensor records counts across three 'count lines'- centre, left hand side (LHS) and right hand side (RHS). The reason for having multiple countlines is so that the sensor can provide more accurate counts at different points across the road, especially picking up pedestrian counts on LHS/LHS count lines.
The data that has been released is disaggregated across the individual countlines. For sensor level counts, it is possible to aggregate all countlines by hourly intervals.
