About Identifying One-Way streets

Each segment in Trapeze4 map data is defined with a From (or start) point and a To (or end) point. One-way streets in the data are identified relative to the From point.

To indicate that a street is one-way from the From point to the To point, a greater than sign (>) is saved in a segment data field. To indicate that a street is one-way from the To point to the From point, a less than sign (<) is saved in a segment data field.

One-way street data is only required for street routing in Trapeze4 applications.
