Traffic Signal Study

County: Fairfax

Intersection: Fox Mill Road & Pinecrest Road

Date: March 2, 2017

Origin and nature of request: Citizen request

An engineering study is required to determine the need for a new traffic signal. The Manual on Uniform Traffic Control Devices (MUTCD), published by the Federal Highway Administration, is nationally recognized as the standard for conducting these engineering studies. Traffic volumes, crash history, operating conditions and physical characteristics are collected and compared to the conditions or “warrants” found in the MUTCD. If one or more of the MUTCD warrants are met, an operational analysis should be performed to evaluate the intersection function, both signalized and unsignalized. Traffic signal control should not be installed unless the study shows that a signal will improve the safety or operations of the intersection. This document provides a summary of the findings of this intersection’s traffic signal study. Study Results and Recommendation:

• Warrants 2 & 3B met • (6) angle collisions w/in 1 year period • Maximum delay 1.74 hrs • Skewed EB side street approach • Recommend installing main line LT lanes • Consider roundabout

A signal is recommended for this location. A signal is not recommended for this location.

List of Attachments:

• Signal warrant analysis • Turning movement count • Crash data for past 3 year period • Aerial and ground photographs • Delay data
