Description:

In May of 2008, MoDOT installed a “Variable Speed Limit” (VSL) system along the I-270/I-255 corridor in

St. Louis. This project evaluated the VSL system and its potential impacts and benefits to the

transportation users. The technical system evaluation focused on three areas - mobility, safety, and public

and police perceptions. The VSL is not performing as desired in terms of improvements to overall mobility

along the corridor, but is providing limited benefits to some segments. Noticeable benefits have been

seen with respect to reduction in the number of crashes during the evaluation period. The driving public

and law enforcement are widely dissatisfied with the VSL system based on their perceptions of benefits to

congestion relief, compliance with posted speed limits, and overall visibility of the current sign

configuration.
