Safety informations on GPS

GPS is more and more used today, and is available on smart phones, as portable GPS, or even integrated into vehicles. These browsers take into account the so-called Points Of Interests (POI). They are also used by drivers for avoiding routes or highways or difficult passages (such as bridges for example for vehicles exceeding height). GPS devices also offer the option to indicate if a road at a coming distance is blocked during a certain defined length.

The algorithm used today to provide route guidance is build such to always trying to come to the initial route calculated whatever blocking portions of a route is indicated. Moreover, the todays systems cannot be managed in an automatic and online way by emergency units or police in order to react automatically to the information proveded to avoid traffic jam in case of fire or accident for example.

The present system provides with a general and generic solution to the aforementioned drawbacks.

System and method description:

The proposed system intends to receive in an automatic and online way information from selected sources, such as emergency units (police, firemen's...), the areas to be avoided during a journey. The information is retrieved from the network (GPS, Internet, GPRS ...) and managed by the proposed system to perform a new calculation of the route guidance. If the GPS is already active and guiding the driver, the system may or may not recalculate the route, depending on the driver choice (automatic recalculation or not of the guidance route), recalculate the position of the area signalled as "to be excluded" by the system relatively of the guidance route.

When the exclusion is ended by authorities, the GPS is also receiving the information of end of the exclusion, and if needed, the route guidance may be recalculated. Figure 1 below is a schematic representation of the guidance route recalculation in case of the area to be excluded is contained into the guidance route previously defined.
