Re-Examining FDOT’s Field Study

On Wednesday, June 12, 2019, FDOT conducted a “Field Inventory” (or study) of the intersection of SR A1A & Red Cox Dr.

The field study states that the Annual Average Daily Traffic (AADT) on SR A1A is 21,500 vehicles per day. However the number of cars exiting Old Quarry Rd. and Red Cox Dr. onto SR A1A was less than the minimum number required to meet FDOT standards.

As a result, FDOT determined that there was insufficient vehicular and pedestrian traffic to warrant a traffic signal on SR A1A at the intersection of Old Quarry Rd. and Red Cox Dr.

Per “Table 3.4-1. Minimum Traffic Volumes” located in Section 3.4 (page 16) of the FDOT Traffic Engineering Manual, the Intersection of SR A1A and Red Cox Dr. more than qualifies to have an “Emergency Traffic Control Signal” installed to allow these emergency vehicles to safely egress onto SR A1A.

Although the driveway of the Island Fire Station (located on the corner of SR A1A and Red Cox Dr.) is located on Red Cox Dr., approximately 28.5 feet off SR A1A, Section 3.4.4 (b) (page 17) of the same Traffic Engineering Manual states “If the emergency service is located off the main roadway and emergency vehicles access the main roadway via a public access street, emergency signals may be erected at the intersection of these roadways.”

    This intersection is a danger to all drivers and something needs to be done to make it safer. Traffic has increased since 2019. FDOT needs to visit on a weekend . Thanks for the card, l was unaware you existed.
