# Lane Position \[SIG]

To define wind loads for live loads, several parameters must be established, including lane positions. These lane positions will be utilized in the sections for **WL AASHTO** and **WL Custom**. This section allows users to specify the relevant lane positions.

## Geometry

Here, the user can specify the center line of the lane, which can then be utilized in the Wind on Live Load AASHTO or Wind on Live Load Custom sections.

**Bridge:** Select the bridge.

**Start Station:** Specify the start station along the PGL.

**End Station:** Specify the end station along the PGL.

**Transverse Offset:** Use this parameter to define the centerline of the lane, consider 0 as the PGL location.
