Traffic Signal Synchronization Project Timeline

Spring 2005 - Fillmore Avenue Traffic Signal Project – City manages Federal Aid project to replace traffic signals along Fillmore Avenue between Best and Main.  Time of day signal coordination patterns developed and implemented for AM, mid-day and PM peak travel times.


Fall 2005 - Sycamore Street/Walden Avenue Traffic Signal Project – City manages Federal Aid project to replace traffic signals along Sycamore and Walden between Michigan Avenue and the city line.  Time of day signal coordination patterns developed and implemented for AM, mid-day and PM peak travel times.


Winter 2007 – Traffic Signal Energy Performance Contract - Incandescent traffic signal bulbs replaced with Light Emitting Diodes (LEDs) on traffic signals citywide.  Energy savings and low interest loans were used to upgrade 100 old traffic signal controller cabinets to modern technology and to install wireless communication between signals along three corridors.  Signals are connected to IQ Central signal software via fiber optic connection.  Basic two-way synchronized timing patterns installed along these three corridors:


South Park Avenue
William Street
Niagara Street


January 2008 – Traffic Signal Energy Performance Project - Michigan Avenue – Additional work added to the Energy Performance Contract to bridge connection between South Park Avenue and William Street.  Signals are connected to IQ Central signal software via fiber optic connection.  Basic two-way synchronized timing patterns installed on Michigan Avenue between South Park and William.


Summer 2008 – Genesee Street Traffic Signal Project – City manages Federal Aid project to replace traffic signals along Genesee Street between Michigan and Bailey.  Project includes wireless communication between traffic signals and a fiber optic connection to IQ Central.  Basic two-way signal coordination implemented.


Spring 2009 - Traffic Signal Energy Performance Project - Delaware Avenue – Additional work added to the Energy Performance Contract to convert old copper interconnect wire on Delaware between Forest and West Mohawk into Ethernet communication.  System is then connected to IQ Central signal software via fiber optic connection.  Basic two-way synchronized timing patterns are installed.


Fall 2009 - Bailey Avenue Traffic Signal Project – City manages Federal Aid project to replace traffic signals along Bailey Avenue between Broadway and the city line.  Project includes wireless communication between traffic signals and a fiber optic connection to IQ Central.  Basic two-way signal coordination implemented.

Spring/Fall 2011 - GBNRTC Signal Retiming and Optimization Project – City is a beneficiary of the GBNRTC managed Federal Aid project to study existing conditions and recommend new traffic signal timing patterns along three City of Buffalo corridors and three NYSDOT corridors.  Time of day signal coordination patterns developed by a consultant and implemented by the City for AM, mid-day and PM peak travel times along these three corridors:


Elmwood Avenue – completed March, 2011
Clinton Street – completed March, 2011
Main Street – anticipated completion November, 2011


Fall 2011 - Main Street Reconstruction Project – Reconstruction of Main Street includes traffic signal replacement and new fiber optic interconnection between traffic signals and back to IQ Central.  Time of day signal coordination patterns were developed for AM and PM peak travel times.  Anticipated completion of this project by the contractor is November, 2011


Spring 2012 - NYSDOT Delaware Avenue Project – NYSDOT manages traffic signal upgrade and interconnect project which includes signals along Delaware Avenue between Nottingham and the city line.  Fiber optic connection to IQ Central and final signal timing to be completed by Spring, 2012.


Spring 2012 - Seneca Street Signal Retiming and Optimization Project - Time of day signal coordination patterns are being finalized by a consultant to be implemented by the City for AM, mid-day and PM peak travel times along Seneca between Michigan and the city line.


Future Project Estimated completion:  Spring 2013 - Jefferson Avenue Signal Retiming and Optimization – Negotiating contract with consultant to study existing conditions and recommend new traffic signal timing patterns to be implemented by the City for AM, mid-day and PM peak travel times along Jefferson Avenue. 


Future Project Estimated completion:  Spring 2013 - Hertel Avenue Signal Retiming and Optimization – Negotiating contract with consultant to study existing conditions and recommend new traffic signal timing patterns to be implemented by the City for AM, mid-day and PM peak travel times along Hertel Avenue. 


The Department of Public Works continues to pursue grant opportunities to further improve our traffic signal system while strategically spending signal improvement funds.  Next step is to build on the existing systems in place by incorporating time of day patterns where we have existing communication to IQ Central. 


We are also testing new detection technology which, if it withstands the test, will be more cost effective and easier to deploy and maintain than the existing inductance loop technology which we currently use.  The addition of more detection to the system will help improve performance of these signal corridors and create a “closed loop” system.
