MAR 7 1984 BOX PACE vehicles), but dropped to a low rate (0.55 accidents/MEV) during 1982. The accident rate again increased during the first six months of 1983 at 3.41/ MEV. However, after installation of an aerial flashing beacon in June, the rate dropped,to 1.06 accidents/MEV for the period July 1 December 31, 1983. 4. Traffic Control: Existing traffic control consists of two-way stop signs for the northbound and southbound (43rd Avenue) approaches supplemented by an aerial flashing beacon installed during June, 1983. Crosswalks with appropriate signage in conformance with FDOT standards are provided across the westbound and northbound approaches. Critical movement analysis during the peak hour (1500-1600) reveals that the intersection operates at level -of -service "B" with short delays to side street (43rd Avenue) traffic. Signalization warrant analysis based on provisions in the Manual On Uniform Traffic Control Devices (USDOT, 1978) do not justify signalization according to the "Minimum Traffic Volume" warrant - minor street volume (43rd Avenue) exceeds the threshold level but the major street volume (41st Street) is only 37% of the minimum. This means that the volume on South Gifford Road is in- sufficient to cause significant delays to 43rd Avenue traffic. The "Accident Experience" warrant cannot be adequately evaluated due to the short time that the aerial flashing beacon has been operating (eight months). At least one year, preferably more, is needed for -meaningful evaluation of inter- section safety. Accident experience since operation of the beacon has been two collisions in eight months. ALTERNATIVES AND ANALYSIS A. Maintain existing traffic control (2 -way stop with aerial flashing beacon). B. Install a traffic signal due to potential hazard traffic volume). RECOMMENDATION (as recommended by the Transportation Planning Committee involving the quantity of school buses and increasing Alternative A is recommended since traffic volumes do not warrant signalization and since insufficient time has elapsed with which to evaluate the effectiveness of the aerial flashing beacon. Specific recomendations are: - 1. Evaluate the effectiveness of the beacon after its one-year anniversary in June, 1984. 2. Proceed to obtain additional right-of-way on the north side of South Gifford Road to (1) provide better sight -distance by removing citrus trees, and to (2) begin implementation of widening South Gifford. Road as approved in the Gifford Area Traffic Improvement Plan The Transportation Planning Committee, at the request of Mr. Judd Barker (School Board representative), unanimously recommends that the intersection be signalized due to the number of school buses using the intersection. Signalization will cost approximately $10,500 for a four-phase signal using in-house personnel to install. Contracted cost is estimated at $25,000. If approved, it is recommended that the cost be included in the proposed FY84-85 Traffic Engineering Department Budget. 84
