A key task in traffic control systems is performed by local traffic controllers. Currently used controllers are microprocessor-based devices that implement advanced local and area traffic control algorithms. The article presents the argument for using hardware solutions and reprogrammable circuits in such devices, as well as the advantages and disadvantages of this type of implementation. A proposed method for the implementation and synthesis of local traffic controllers in the form of specialized single-chip hardware devices is presented. Thanks to this, in addition to device reliability, their processing speed increases significantly. This allows for the implementation of additional functionalities previously available in classic controllers only as separate modules.The control device that performs control at the lowest level of the traffic control system is the local controller. These devices are directly responsible for traffic control at an intersection. (…)
