The article outlines the development of a 4- to 16-group user-friendly personal computer (PC) chipset-based traffic controller for local intersections, which was developed by Pacific Traffic Technology. The research and development team aimed to develop a cost-effective traffic controller with: (1) reliability; (2) user-friendly operation; (3) an ability to evolve with user requirements; and (4) considerably different new technology. The controller should be easily configurable to control between four and 16 vehicle and pedestrian groups, through adaptive modelling of real-time traffic conditions and a stored historical record of traffic conditions. A comprehensive performance measurement facility should be included, for continual monitoring of vehicle volume and actual vehicle throughput. The controller's removable flat panel LCD TOUCH VGA screen provides a user-friendly interface, for selecting real-time geometric displays and easily implemented operational modification functions. The distributed traffic signal switching display methodology uses the 'data highway' principle, through a local intersection communication network and distributed microprocessor control. The controller has undergone field trials, and simulation modelling of projected traffic, to evaluate its user interface and operational performance. For the covering abstract see IRRD 877920.
