Other periods may be necessary if the nature of the use generates significant traffic outside of these periods or on weekends. Periods may be omitted if evidence is provided that the project generates an insignificant amount of traffic during the peak of the background traffic (e.g., school dismissal time typically precedes the afternoon peak hour).In addition, Corradino will collect the following key relevant data for the preparation of the traffic impact study: <br />• Intersection control and geometry, turn lane lengths• Signal timing data• Historical counts for trend estimation• Roadway classification, maintaining agency, number of lanes, speed limits• Video imagery of congestion hot spots and queue backups• Vehicle classification data• FDOT Peak Season Adjustment Factor report for the latest year available <br />Existing Conditions/Demand Volumes <br />Corradino will adjust the raw manual turning movement counts and road segment tube counts. The raw counts (segment or intersection) shall be adjusted to reflect peak-season conditions using FDOT’s most recently published Peak Season Conversion Factor (PSCF) for the week of the year in which the count was collected. Raw counts up to one year old may be inflated to existing conditions using the same growth rate assumed for future growth. <br />Segment volumes used for level of service analysis shall be based on a traffic volume count, not by summing volumes entering and exiting adjacent intersections. The peak-hour turning movement volumes to be analyzed should be the 60-minute interval within the two-hour count period with the highest entering-volume sum. <br />Future Background Conditions/Demand Volumes <br />A growth factor shall increase existing traffic counts to the project’s build-out year or other horizon year, depending on the nature of the entitlement being sought. The growth rates shall be from established count databases. The historical growth rate should be based on at least three years of historical counts, if available, unless
