Traffic Engineering Projects

Auburn Traffic Signals System
Improvement Project

Auburn, New York


Fisher developed a systematic approach to upgrade all 20 city-owned traffic signals to current standards with an eye toward a future desire of installing a wireless GPS Traffic Signal Pre-emption System including outfitting the emergency response vehicles with wireless transmitters. An equipment inventory and condition evaluation, coupled with intersection accident analysis and identified operational issues was performed and all traffic signals were ranked. Six (6) intersections were selected as priorities for immediate upgrades, and we provided the design in accordance with all of the current standards. Multiple intersections received pedestrian facility improvements in the form of: sidewalks, sidewalk ramps, marked crossings, pedestrian push button detection, and pedestrian crossing indications.

Center City Two-Way Conversion

Rochester, New York


Given the character change of downtown Rochester over the past few decades and the increasing need to provide better pedestrian and bicycle safety and accommodations, provide better access to commercial properties, improve wayfinding and reduce driver confusion, the City desired to convert St. Paul Street and North Clinton Avenue between Main Street and the Inner Loop to two-way traffic. This project consisted of milling and resurfacing the roadway, signal system modifications at thirteen intersections, spot watermain and hydrant relocations, spot curb and sidewalk replacement, modification of curb bumpouts, new pavement marking installation, and new signage..



APWA Project of the Year Award

Diverging Diamond - I-590/ Winton Road Interchange

Rochester, NY


Fisher Associates was sole sourced by NYSDOT and worked closely with the Region 4 Planning and Programming Group to provide traffic volume forecasts and capacity analyses for the Winton Road/ 590 Interchange. We evaluated the potential impacts and benefits associated with several design alternatives by creating complex simulations. Fisher provided several simulation alternatives that included a triple left exit ramp and variations of partial cloverleaf interchanges.


The final alternative involved an innovative Diverging Diamond Interchange, one of the first applications in the United States and the first in New York State. The project was recognized by Institute of Transportation Engineers (ITE) and the American Council of Civil Engineers (ACEC) for transportation project achievement along with innovative 4D virtual modeling technology for design optimization and public involvement.

Elmira Signal Upgrades
Corridors 1 & 2

City of Elmira, New York


Fisher Associates was responsible for Highway Safety Investigations for 33 signalized intersections in the Central Business District to improve traffic flow
and pedestrian safety within the City. Additionally, an extensive Road Safety Audit was conducted to identify high accident locations and patterns and identify specific deficiencies that safety improvements would alleviate.


Work included the design of upgraded controllers and cabinets; a closed loop hardwire interconnect system; intersection safety upgrades to improve pedestrian safety including the addition of signal backplates for the east/west streets; and recommended signal timing modifications. Signal timings (cycle length, offsets, phasings, pedestrian timings, split lengths and time-space diagrams) were developed and implemented for the City.  Upgrades to the study intersections included signal timing treatments, signal backplates, new pedestrian signals, and updated road markings. Fisher also provided building oversight and design support during construction.
