Please refer to Figure 3. Figure 3 is a flow diagram of a processing procedure 30 for transmitting a traffic event report to a server by a personal navigation device in accordance with a second embodiment of the present invention, wherein the traffic event report corresponds to a traffic event. The processing program 30 includes the following steps: Step 300: Receive a plurality of traffic event reports corresponding to a traffic event from the plurality of personal navigation devices; Step 302: Determine, according to the plurality of traffic event reports, that the traffic events are occurring; Step 304: Determine an affected area of the traffic event according to the location of each of the plurality of traffic incident reports; Step 306: Generate a traffic alert according to the plurality of traffic incident reports; Step 308: transmit the traffic Alert to a person's navigation device.

From a server perspective, the server can receive a plurality of traffic event reports (step 300). The traffic incident report may be a self-built notification of the user and/or a self-built notification of the navigation device, and may be transmitted by a plurality of personal navigation devices. For example, five different personal navigation devices used by five different users may transmit notifications to the server regarding the traffic event (which may be a collision, road construction, road congestion, etc.). Each notification can also contain different types of information, such as location, direction, time, street name, street address, etc. After a predetermined period of time (eg, five minutes, ten minutes, thirty minutes, etc.), the server can receive notifications from the personal navigation device. Using the plurality of notifications, the server can determine that the traffic event is occurring (step 302), and can also determine the area affected by the traffic event (step 304), such as a one-kilometer congestion on the northbound road on the interstate highway. The server may convert the information received by the plurality of traffic event reports into a traffic alert (step 306). Multiple traffic incident reports can correspond to an area but contain different information. The server can select the type of traffic event from the traffic incident report based on location and/or clarity. For example, a first user may submit a first traffic incident report including a road congestion at the first place, and a second user may submit a second accident at the second location. The second traffic incident report. If the second location is closer to the street where the road is blocked, and both the first and second traffic incident reports indicate the same heading, the second user may have more specific information about the traffic event than the first user. News. Since the first user may only see the road congestion, and the second user may already know the cause of the road congestion (such as road construction, car accident, road closure, etc.), since the second user is closer to the traffic event, The server can select "car accident" as the type of traffic event. Or, because the "car accident" is more clear than the "road congestion", the server can choose "car accident" as the type of traffic incident. Once the traffic alert has been generated, the server can transmit the traffic alert to the personal navigation device (step 308). Traffic incident reports can be transmitted in several different ways, such as broadcast, internet connection, short message service (SMS), wireless communication, text...etc. The traffic incident report can be made downloadable and transmitted to the requesting personal navigation device when the server receives the request from the one person navigation device. Information about the traffic event can be transmitted based on a geographic area. For example, information about the traffic event may be transmitted to a personal navigation device within a predetermined range of the traffic event, and/or to a personal navigation device within a predetermined time period in which the traffic event occurred. The server can delete the notification according to the predetermined overdue period (such as five minutes, fifteen minutes, thirty minutes, etc.).

When the personal navigation device receives information about the traffic event, the personal navigation device can display a representative image of the traffic event on one of the personal navigation devices. The personal navigation device can arrange a route or detour away from the traffic event. The personal navigation device can display the traffic event in a form. The personal navigation device can provide a voice notification of the traffic event to the driver.

When the traffic event is resolved, the server may receive a notification regarding the traffic event, and as if the overdue notification was deleted, the traffic event is deleted and the traffic event report is no longer transmitted to the personal navigation device. The server can receive a user self-built notification indicating that the traffic event is no longer valid, or that the traffic at the original occurrence of the traffic event has been smooth. At the same time, the server can also delete the traffic event and no longer transmit the traffic event report to the personal navigation device.

For the navigation device self-built notification, the server can receive the navigation device self-built notification from the personal navigation device. Compared with the user selecting the traffic event from a form or manually inputting the traffic event by other means, the personal navigation device can automatically determine the traffic event, such as position, direction, speed, according to the information collected by the user. Wait. For example, the personal navigation device can utilize the position and orientation of the navigation device to determine the street in which the navigation device is located, and the direction in which the navigation device is traveling. The map database contains not only the street name but also the usual speed of each street, so the navigation device can easily determine whether the speed of the navigation device is lower than the normal speed of the street on which the navigation device is traveling. Under such conditions, if the speed of the navigation device is lower than the normal speed by more than a predetermined threshold, the personal navigation device may generate a navigation device self-built notification and transmit it to the server. If the navigation device is stopped, the navigation device may also generate a navigation device self-built notification to the server. The personal navigation device may also require the driver or passenger to identify the traffic event when the personal navigation device generates a notification based on the collected information. In this way, although the personal navigation device may not be able to distinguish whether a traffic incident is road congestion or road closure, and the traffic incident can still be provided to the user to determine that the road is blocked or the road is closed, the notification transmitted to the server may include The traffic event selected by the user.

The present invention provides a method of transmitting a traffic event to a personal navigation device that can be user oriented, device oriented, or a prior art notification that the user of the personal navigation device cannot be notified based on traffic events entered by other personal navigation devices. It can be a mixture of the above two. The above method enables traffic events to be quickly and correctly detected and broadcast to other personal navigation devices.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
