1!H:l - _ Designated Local and Regional Transportation Facilities .. As previously defmed, both NE 192nd Street and Sunny Isles Boulevard are designated as evacuation route links to the mainland. These two major roadways provide connections to the north-south evacuation routes. .. - - .. Roadway Level of Service Standards .. The Level of Service (LOS) is a standard summary of roadway operating conditions. The concept of highway capacity is intended to define the maximum number of vehicles able to travel on a specific section of roadway during a given period of time, usually by the hour or the day. In rdationship to a road's actual capacity, LOS is a qualitative measurement of the maximum number of vehicles using a road without detracting from the road's operating condition. Intersections are often described and rated according to LOS designations. The standard transportation planning levels of service are explained below: .. .. - .. - - LOS A: The highest LOS describing primarily free flowing traffic at average traffic speeds. Vehicles are totally unimpeded and intersection delays are minimal - .. LOS B: Vehicles travel at reasonably unimpeded conditions at average speeds. Their ability to maneuver within the traffic stream is only slightly restricted and stopped delays are slight. - ... LOS C: Traffic flow is considered stable. A vehicle's ability to maneuver and change lanes is somewhat restricted and longer queues and/or adverse signal coordination may reduce the average speed. .. - .. LOS D: Borders on a range where even small increases in traffic could result in reductions in the speed and increased delays. Problems may result from poor signal coordination or traffic volumes. .. .. - LOS E: Traffic flow is characterized by low operating speeds and significant delays. The problems may be rdated to volumes, high signal density and timing, and substantial queuing at important intersections. - - LOS F: This designation represents delayed and congested roadways and intersections. Traffic flow generally moves at extremdy slow speeds and waits at intersections are lengthy. - - .. .. Service volumes refer to a roadway's capacity for various levds of service. They vary according to the type of road, the number of lanes, and the number of signals per mile. The LOS designations for existing roads were developed and refined by the FDaT. The two following tables provide information on the two-way peak hour service volumes for different roadway types and the relationship between the various levels of service and the average travel speeds along typical Florida arterial roadways during peak travd hol.1IS. .. - .. - - Sunny Isles Comprehensive Plan - Existing Conditions I Background Documents 39 - ..
