On Monday the complaints are on the table; the analysis of the count data is not.
At the hotspot, cars are double-parked, the counting station records the peak, and nobody sees the two together. Whoever has to explain the situation afterwards opens the count data, timetable and map one at a time and does the sums by hand.
1overload dayOn a Sunday, cars are double-parked at the viewpoint and two complaints come in.
3departmentsPublic order, tourism and transport planning each go over that same Sunday separately.
3data sourcesEach department opens count data, timetable and map on its own and works out the peak hours by hand.
0figures in the reply to the councilThree weeks later the council asks about that Sunday, and the reply goes out without a single hourly figure to back it up.
One Sunday, three departments, the same three sources, and the reply to the council contains not one hourly figure backed by data. The 35% reduction in overload days from the data sheet assumes that the recurring pattern is analysed once, stored on the map and still retrievable there three weeks later.
This sequence describes a typical weekend at a hotspot. The percentage comes from the headline figure in the data sheet, not from this worked example.
