Part of: Microcomputer Applications in Transportation II


A new computerized microscopic traffic simulation model ROADTEST is described. The model a general purpose one, permits simulation of any vehicles including trains and fixed route transit vehicles such as buses and light rail vehicles in addition to cars, high occupancy vehicles, trucks and pedestrians. It can be used to model almost any urban road and rail network from a single intersection to an area of a city, including freeways, railroads, transit routes, and pedestrian facilities. There are no restrictions on the size, shape, or composition of the network. Any number of vehicle paths such as a traffic lane, rail line, or pedestrian crosswalk can be placed in any configuration. Paths are made up of any number of circular arcs and straight lines. Almost any traffic control situation can be modeled including signal preemption, railroad gates, lane control, lane blockages, on-line or off-line transit vehicle stops, variable speed signs, stop signs, and yield control.
