Description
Summary:Data was collected on the marine traffic and VHF-FM marine communications channel usage at Detroit and Port Huron, Michigan, during the period of 6-24 July 1978. The marine traffic data was recorded by means of time lapse photography of a radar display. Recordings were made of the communications on VHF-FM maritime mobile Channel 16 as received at each site. The daily average of marine traffic, including large and medium vessels, and tugs-in-tow on the Detroit River is 60, with the daily average of small vessels being 598. The daily average of marine traffic, including large and medium vessels on the St. Clair River is 34, with the daily average of small vessels being 797. Approximately 300 hours of communications on VHF-FM Channel 16 were recorded and monitored to determine channel efficiency (i.e., percentage of valid messages) and utilization. At Detroit, the efficiency is 55.85%, utilization 19.49%. At Port Huron, the efficiency is 59.50%, utilization 17.88%. (Author)
