Export Transit Screenline Results

This tool is used to aggregate transit volumes for a specified line filter based on a given screenline aggregation file. For auto volumes, please see 'Export Screenline Results' tool.

A screenline is defined as a collection of count stations, while a count station is encoded in a link extra attribute. A count station can belong to one or more screenlines.

The screenline definition file structure assumes a header line followed by lines. For example,

Screenline GID	Station GID
T1001I	100002
T1001I	100012
T1001I	100022
T1001O	100004
T1001O	100014
T1001O	100024
