Screenlines

Screenlines are imaginary lines typically drawn along features such as rivers or railways, which have a minimum number of crossing points, making it more manageable to count traffic going from one side to the other. Symbology is based on the COUNTYEAR_EN field (Both = Count Collection during All Years / Even = Count Collection during Even Years / Odd = Count Collection during Odd Years), which describes when the count takes place.

 A screenline (e.g. LN02, LN10) is made up of several stations placed to count east-west or north-south travel, which in total, capture all major travel routes across the imaginary screenline. The screenlines are located along geographical barriers, i.e. rivers, greenbelt – generally where several major transportation facilities are the main flow. To be truly representative of the flow, there is a station at each intersecting road, transit, and bike/walkway path on the screenline.
