An active safety system for a workplace comprising: at least a first microwave activator, associated with a vehicle operating in the workplace and configured to activate a transceiver, TAG, (13, 21) at a first distance; at least a first lower frequency activator, associated with a vehicle operating in the workplace and configured to activate a transceiver, TAG, (13, 21) at a second shorter distance than said first distance; at least one transceiver, TAG, (13, 21), associated with operators or fixed structures inside the workplace and adapted to receive activation signals from said microwave activator and from said first low frequency activator and to transmit a response signal upon receiving the activation signal; at least one receiver (12, 18), associated with a vehicle operating in the workplace and adapted to receive the response signal of said at least one transceiver, TAG, (13, 21), upon receiving the activation signal; a processing, storage and control unit associated with said first and second activators (10, 11), said receiver (12, 18), and the vehicle traction control system, said processing, storage and control unit being adapted to act on the direction of travel and on the speed of the vehicle if an event related to a possible interference between said vehicle and said operators or fixed structures is detected based on the signals received by said receiver (12, 18) characterized in further comprising a geo-referenced position detector associated with said processing, storage and control unit; local storage means adapted to contain at least one map of the work area in which different safety rules correspond to sub-areas of the work area, said processing, storage and control unit being further adapted to determine the current position of the vehicle and to act on the direction of travel and on the speed of the vehicle based on said safety rules, if an event related to a possible interference between said vehicle and said operators or fixed structures is detected based on the signals received by said receiver (12, 18). at least a first microwave activator, associated with a vehicle operating in the workplace and configured to activate a transceiver, TAG, (13, 21) at a first distance; at least a first lower frequency activator, associated with a vehicle operating in the workplace and configured to activate a transceiver, TAG, (13, 21) at a second shorter distance than said first distance; at least one transceiver, TAG, (13, 21), associated with operators or fixed structures inside the workplace and adapted to receive activation signals from said microwave activator and from said first low frequency activator and to transmit a response signal upon receiving the activation signal; at least one receiver (12, 18), associated with a vehicle operating in the workplace and adapted to receive the response signal of said at least one transceiver, TAG, (13, 21), upon receiving the activation signal; a processing, storage and control unit associated with said first and second activators (10, 11), said receiver (12, 18), and the vehicle traction control system, said processing, storage and control unit being adapted to act on the direction of travel and on the speed of the vehicle if an event related to a possible interference between said vehicle and said operators or fixed structures is detected based on the signals received by said receiver (12, 18) characterized in further comprising a geo-referenced position detector associated with said processing, storage and control unit; local storage means adapted to contain at least one map of the work area in which different safety rules correspond to sub-areas of the work area, said processing, storage and control unit being further adapted to determine the current position of the vehicle and to act on the direction of travel and on the speed of the vehicle based on said safety rules, if an event related to a possible interference between said vehicle and said operators or fixed structures is detected based on the signals received by said receiver (12, 18).
