Abstract
In a method for reducing risks in road traffic, using a motor vehicle an information signal is generated and transmitted to an analysis unit. The information signal contains a position of the corresponding motor vehicle and an associated hazard level. Using the analysis unit, the position is assigned to a route section and a risk characteristic value is determined as a function of the hazard level. Using the analysis unit, a risk signal is generated based on the risk characteristic value and provided to at least one traffic participant.
Claims20
A method for reducing risks in road traffic, wherein
- using each of two or more motor vehicles, generating and transmitting an information signal to an analysis unit;
- wherein each information signal contains an absolute position of the corresponding motor vehicle and an associated hazard level;
- using the analysis unit, assigning each absolute position to one of a plurality of route sections and determining a risk characteristic value for each of the route sections as a function of the hazard level;
- using the analysis unit, generating a risk signal based on at least one risk characteristic value and providing the risk signal to at least one traffic participant;
- wherein the hazard level is assigned to a corresponding route section depending on the associated position, and the risk characteristic value is determined for the corresponding route section as a function of the hazard level assigned thereto;
- and
- using the analysis unit, statistically evaluating the hazard level assigned to the corresponding route section in order to determine the risk characteristic value for the corresponding route section.
A system for reducing risks in road traffic, wherein
- the system comprises a communication interface, which is configured to receive at least one information signal from two or more motor vehicles and to transmit said at least one information signal to an analysis unit of the system;
- said at least one information signal comprises an absolute position of the corresponding motor vehicle and an associated hazard level;
- the analysis unit is configured:
- to assign the absolute position to one of a plurality of route sections and to determine a risk characteristic value for each of the route sections as a function of the hazard level;
- and
- to generate a risk signal based on the risk characteristic value;
- the communication interface is configured to transmit the risk signal to at least one traffic participant;
- and
- the analysis unit is configured:
- to assign the hazard level to a corresponding route section depending on the associated position;
- to determine the risk characteristic value for the corresponding route section as a function of the hazard level assigned thereto;
- and
- to statistically evaluate the hazard level assigned to the corresponding route section in order to determine the risk characteristic value for the corresponding route section.
