QUEUING AT DRIVE-UP WINDOWS

The development of drive-up windows may cause serious problems, where (a) additional fuel is consumed and pollutants are generated by vehicles, in queue, waiting to be served; (b) serious off-site operational problems may occur due to queued vehicles extending onto adjacent streets; and (c) queued vehicles often interfere with the use of on-site parking spaces. Queuing theory is used in the development of a procedure to identify and quantify the magnitude of the problems associated with drive-up windows. Estimated arrival rates and service rates are used to predict a failure rate, i.e., the percentage of time in which a queue length will exceed a selected length of queue. The average time of vehicles in the system, estimated from arrival and service rates, is used to calculate the amounts of air pollutants generated and the fuel consumed. An example problem is included. A brief description of applicable queuing theory is included. Some geometric design guidelines are suggested for the efficient on-site operation of drive-up windows.
