Variable Speed Limit (VSL) Signs

Description

This project represents the installation of Variable Speed Limit (VSL) signs by LFUCG. VSL signs will be operated from the LFUCG Traffic Management Center. Speed limits will either be updated from the TMC based on known traffic conditions or on an automated basis from roadside detection equipment. Legislative statute enabling variable speed limits will need to be further discussed and established prior to design and implementation.

Lead agency is LFUCG (Traffic).
