Dear Supervisor Feiner:
Thank you for your correspondence concerning the intersection of Route 100 (Central Avenue) with Underhill Road and Old Army Road in the town of Greenburgh, Westchester County. As youreference in your letter, the New York State Department of Transportation (NYSDOT) has a study underway to determine whether a left-turn signal phase for the side roads would improve the operation of the traffic signal at this intersection. As part of this study, NYSDOT is also evaluating whether the existing traffic signal equipment can physically support the signal equipment that would be needed should the decision be made to install left-turn signal indications for the side road approaches.
In your letter, you request an update on the status of our study. The analysis of the accident history and the signal equipment is ongoing. Our Traffic Safety & Mobility office was not able to do a field review of the intersection before the holidays. Now that school is back in session at Edgemont High School and the traffic volumes are returning to a normal state (not impacted by holiday traffic), NYSDOT will conduct fieldreviews to analyze the operation of the signalized intersection during morning and afternoon hours. It is anticipated that the study will be completed by the end of February 2018.
If you have any further questions concerning this review, please feel free to contact Adam Levine, our Regional Traffic Safety and Mobility Engineer, at (845) 437-3396.
