Abstract:

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.
