Embodiment 1

[0117] Step 1. The location service terminal obtains the location information of the current terminal in real time by receiving satellite navigation data, and obtains real-time traffic information at a certain time interval (for example, 5 minutes). Ways to obtain real-time traffic information include: receiving traffic information channel (TMC) information through FM fixed frequency band; receiving TMC information through China Mobile Multimedia Broadcasting (CMMB) receiving channel; obtaining TMC information through GPRS network.

[0118] Step 2. The location service terminal plans the navigation route according to the current location and the destination information input by the user. The newly acquired real-time traffic information is taken into consideration when planning the route. length, if the length of the congested road section exceeds a certain value (for example, 500m), the congested road section will be avoided when planning the route.

Embodiment 2

[0120] Step 1. The location service terminal obtains the location information of the current terminal in real time by receiving satellite navigation data, and obtains real-time traffic information at a certain time interval (such as 5 minutes), and at the same time, the location service terminal provides navigation services for the user according to the pre-planned route ( vehicle driving guidance);

[0121] Step 2. Each time the location service terminal obtains real-time traffic information, it checks whether there is a congested path ahead of the currently planned path;

[0122] Step 3. If it is found that there is a congested road section on the route ahead according to the latest real-time traffic information, and then obtain the length of the congested road section, if the length of the congested road section exceeds a certain value (for example, 500m), then ask the user whether to divert or Automatically plan new paths for users.

Embodiment 3

[0124] Step 1. The location service terminal obtains the location information of the current terminal in real time by receiving satellite navigation data, and obtains real-time traffic information at a certain time interval (such as 5 minutes), and at the same time, the location service terminal provides navigation services for the user according to the pre-planned route ( vehicle driving guidance);

[0125] Step 2, the location service terminal detects whether there is a congested road section within a certain distance (for example 5km) ahead of the path according to the latest acquired TMC information at a certain time interval (for example 2 minutes or 3 minutes);

[0126] Step 3. If it is found that there is a congested road section on the route ahead according to the latest real-time traffic information, and then obtain the length of the congested road section, if the length of the congested road section exceeds a certain value (for example, 500m), then ask the user whethe...

Abstract

The invention relates to a navigation method and navigation equipment. The navigation method comprises: obtaining road traffic information; selecting a route from at least one optional route between a starting place and a destination; judging whether a congestion section exceeding the scheduled length exists in the selected route based on the obtained road traffic information; if yes, selecting a route from other optional routes once again; and judging whether the congestion section exceeding the scheduled length exists in the selected route once again until the number of the rest optional route is zero, if not, determining the selected route as a navigation route. The navigation method also comprises: judging whether the congestion section which exceeds the scheduled length exists in the route at regular time in the process of travelling in accordance with the navigation route; and if yes, sending a congestion hint to users. By utilizing the method and equipment provided by the invention, whether congestion really exists can be determined more accurately so as to more accurately plan the navigation route and provide users with high-quality service.

Description

technical field [0001] The present invention relates to vehicle navigation, and more particularly, to a method and device for navigation based on the length of congested road sections. Background technique [0002] A location service terminal refers to a device with a location service function and related functions. A navigation device is an example of a location service terminal. Its working principle is: the navigation device determines the location coordinates of a specific location, and matches it with the location coordinates recorded in the electronic map stored by itself, so as to determine the navigation device equipped with the navigation device. The exact position of the object in the electronic map. The navigation device can be a vehicle terminal, a portable navigator, a mobile phone terminal, and the like. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation device will calculate the n...
