USING PRE-EMPTION FOR DEPENDABLE URBAN VEHICLE TRAFFIC

A new approach for design and implementation of urban vehicle control system is proposed. The vehicle streams on lanes are considered similar with the streams of instructions in multitask programs. Real-time scheduling algorithms are used to allocate the green lights to phases. An adaptive component is used to calculate new vehicle flow parameters when a failure appears as a consequence of an accident. The real-time schedulers use the parameters to obtain new feasible resource allocations.
