[0004] The above scheme is still based on data analysis and processing in the networked state, and the accumulated road network information is used to obtain the navigation distance of each road section, and finally obtain the path with the shortest road distance as the planned route, which still cannot be realized in the offline state Accurately obtain the congestion situation of the target line. Further, the obtained line congestion situation does not correspond to the congestion situation in the current time period, and there is a large error with the actual congestion situation; therefore, it is necessary to provide an offline state acquisition line Method and system for road conditions to solve the above problems

Embodiment 1
[0096] Please refer to figure 1 , figure 2 with Figure 7 , Embodiment 1 of the present invention is:
[0097] A method for obtaining road conditions of a line in an offline state, comprising:
[0098] The server divides a day into more than two time periods;
[0099] Specifically, a day can be divided into 6, 8, 10, 12 or 24 time periods, and the time corresponding to each divided time period can also be flexibly configured according to requirements, which can be equidistant or non-equidistant; For example, a day is divided into 24 time periods, that is, every hour is a time period; the more time periods are divided, the finer the division of the time of the day, and the road elements corresponding to each time period obtained accordingly The reflected road condition information is also more accurate.
[0100] The server divides the road segment in the map into more than two road elements;
[0101] Specifically, each road in the map can be divided according to a preset...
Embodiment 2
[0126] Please refer to Figure 3 to Figure 6 , the second embodiment of the present invention is:
[0127] A system for obtaining road conditions of a line in an offline state, including a server and a client; the client can be a smart phone, a tablet or a computer;
[0128] The server may include a preset module 1, a division module 2, a first acquisition module 3 and a second acquisition module 4; the second acquisition module 4 may also include a third acquisition unit 41 and a fourth acquisition unit 42;
[0129] The client can include a third acquisition module 5, a fourth acquisition module 6, a fifth acquisition module 7, a sixth acquisition module 8, a seventh acquisition module 9, an upload module 10, a storage module 11 and a statistical analysis module 12; The sixth module may also include a first acquisition unit 81, a second acquisition unit 82 and a selection unit 83;
[0130] Specifically, the preset module 1 is used for the server to preset more than two time...

Abstract
The invention provides a method and a system for acquiring the traffic condition of a route offline. The method comprises the following steps: the traffic condition information of each road element in each time period is acquired; the traffic condition weight of each road element in each time period is acquired according to the traffic condition information, and the traffic condition weights are stored into a client; the client acquires place-of-departure information, destination information and the current time period; a traffic route is acquired according to the place-of-departure information and the destination information; the road elements covered by the traffic route and the traffic condition weights of the road elements in the current time period are acquired; and the traffic condition weights of the road elements are accumulated to acquire the weight value of the traffic route. By using the method and the system, congestion of a route can be accurately acquired offline.
Description
technical field [0001] The invention relates to a method and system for acquiring road conditions of a line in an offline state. Background technique [0002] With the sharp increase in the number of cars owned by urban residents, road traffic has become unsatisfactory. For the convenience of driving, it is necessary to know the current road conditions in time. In the existing technology, the road congestion situation can be obtained after being connected to the Internet through third-party software, but in the case of offline, such as network connection failure, poor network signal and other reasons caused by network disconnection, the user cannot obtain timely At this time, it is very likely that people will waste a lot of unnecessary time on congested roads, and the time delay will also seriously affect people's mood. [0003] The application document with application number 201010122383.1 discloses a method and device for navigating according to road conditions. By obta...
