An approach is described to the functional design and analysis of a typical access facility of a dual-mode system concept being researched at General Motors Research Laboratories. The procedure uses a discrete-event simulation model to analyze the performance capability of the facility during the peak demand period and to establish the design values of the critical elements of the access facility. After several design iterations and analyses, a typical access module was adopted. The most critical element was found to be the preinspection queuing area. The analysis revealed that the queuing area would require a storage capacity for 38 vehicles, given a maximum waiting time of 6 min and the requirement that all vehicles be stored off the feeder arterial street. The entrance module would have three vehicular inspection and automation bays, measure 29.6 x 310.9 m (97 x 1020 ft), require 9308 sq m (2.3 acres) of land, and have a processing capacity of 360 vehicles/hour. The performance and design characteristics of the entrance module would then be fed into a land requirement model, along with peak-hour loadings, to estimate land consumption effects of the access facilities on the affected communities in a case study area.
