Traffic Signal Improvements

Project Summary:

In fall 2010, the City applied for and received a grant to improve traffic signals throughout the City.  Vehicular detection will be upgraded from magnetic induction loops to wireless sensors.  Wireless sensors will also be installed at various locations as permanent count stations.  Utilizing these and other counts, the traffic signals throughout the City will be re-optimized.  These permanent count stations will also assist the City in monitoring traffic flows in the future and further optimizing signals.  MoDOT and the City of Ladue are also taking part in this project and upgrading traffic signals at Ladue Road and I-170 and at Ladue Road and Hunter Avenue.  The total project cost is approximately $350,000, with the City contributing $60,000, MoDOT contributing $5,500, Ladue contributing $4,500, and the grant covering $280,000. 

Schedule:

Gerstner Electric has completed installing the equipment, with only punchlist items remaining.  Crawford, Bunte, Brammeier (CBB) has completed their re-optimization design, and changes will soon be implemented.  The changes won't be noticeable to most motorists, but they should help improve the flow of both pedestrian and vehicular traffic.
