The Hotels where large scale events are held, such as conferences and banquets, may often have periods where traffic flows substantially exceed the recommended planning figure. If a hotel’s owner or
developers require it, planning criteria should be amended to a higher value, to ensure the elevator system can cope with such demands. Ideally large suites should be located on lower levels. What is an acceptable service interval in a hotel can vary greatly according to its type and location. In smaller, older or provincial establishments longer intervals up to 60 seconds can be acceptable.
In modern, international hotels not more than 30 seconds will be acceptable. In addition to guest elevator systems, most hotels will require provision of separate elevator systems for staff movement, catering supplies, linen and other purposes.
affix flow in hotels is dependent on the type of hotel and its layout. Traffic peaks normally occur in the early morning and in the evenings, as guests leave and enter, or access the common facilities, such as restaurants and bars. At these peak times, traffic flow can be approximately 10 per cent (5 per cent in each direction) of the hotel guest population requiring elevator service in a five minute period. In the absence of other estimates, this value is used for planning.
