On-Call Traffic Signal Design


Location:  Various Counties, New York
Client:  New York State Department of Transportation, Region 10
Construction Cost: $625,000

This project included various signal designs for New York State roadways in Nassau County.

The designs included the preparation of base mapping including field edits, preliminary design of traffic signal layouts, preparation of estimates and table quantities, determining locations of underground and above ground utilities, and evaluating use of span wire versus mast arm signal designs. Final design plans were developed for new signal locations, full signal rebuilds, the conversion of existing firehouse flashing beacon to a full three-color control, new signal installation of moderate complexity, addition of pedestrian crossing signals, full upgrades to existing signalized intersections, addition of dual yellow warning beacons to existing overhead sign assemblies, etc.
